    LEVELING DEVICE FOR REGISTRATION BOTTOM COVERS AND ASSOCIATED LEVELING PROCEDURE
    DESCRIPTION
    5
    OBJECT OF THE INVENTION
    The present invention falls within the technical field of registration wells and openings for registration in underground works, and refers in particular to a leveling device 10 for manhole covers, especially designed for those mouths located on surfaces with slope, as well as to the procedure of construction of registration mouths that makes use of said device.
    BACKGROUND OF THE INVENTION
    fifteen
    The development of urban areas entails the execution of infrastructure construction works, in order to provide these areas with the necessary services, mainly water, energy and telecommunications, as well as the evacuation of sewage and stormwater. The infrastructures for these services 20 are basically formed by conduits for the transport of wiring or fluids of various kinds, registration and / or distribution elements (cameras, boxes or wells), and auxiliary elements such as cabinets or spillways.
    These infrastructures, of a linear nature, usually involve the execution of a high number of kilometers of pipelines and their corresponding registration elements, which makes it necessary to optimize their execution and find durable construction solutions that require reduced maintenance, given the volume they represent and the cost they entail.
    30 The registration elements in urban service infrastructures, generically referred to as "wells", are usually constructed in the form of hollow cylindrical columns, executed as a general rule by joining a plurality of prefabricated concrete cylindrical rings, to thereby manage to reduce completion times and costs.
    The upper or mouth termination of said wells usually consists of a prefabricated frustoconical element, generally of concrete, on whose face of smaller diameter a closure element formed by a fence or frame and a cover, generally of cast iron, is placed. The lid can be attached to the fence by means of a hinge or 5 simply by resting on it.
    On the other hand, the concrete cone trunk can be symmetric or asymmetric; in both cases it is hollow, with respective lower and upper circular openings. The fence is supported on the upper opening, which is then adhered to the 10-cone trunk by mortar or concrete.
    Since the prefabricated elements are marketed in previously determined and standardized dimensions, in many cases the succession of hollow cylindrical rings that make up the well does not allow the fitting of the upper cover to the exact level 15 of the flush of a road, so it is necessary to raise the fence and the lid linked to said fence by adding a small concrete thickness.
    This circumstance is accentuated when the slope of the road has a certain slope since, as it is necessary that the axis of the well is always orthogonal to the horizontal of the land, the fence and the upper surface of the cone will not be parallel, a circumstance that makes it necessary solve it by concrete in situ.
    This constructive solution, very common in the execution of urban service registration wells, including those located on roadways, is not without problems, since there are numerous cases in which seats have been detected between fence and cover due to poor execution, as well as lack of resistance to high loads transmitted by road traffic to the surface.
    This phenomenon occurs not only in rainwater and sanitation registration wells, but also in electrical and telecommunications supply registration chambers, where in many cases the upper termination of access is also resolved with these truncated conical elements and their corresponding fence. and cover.
    DESCRIPTION OF THE INVENTION
    The object of the invention consists of a leveling device for covers of urban service registration mouths, which makes it possible to compensate for differences in inclination between the fence and the lid of said registration mouth and the plane defined by a road with a slope determined, road in which the manhole is located.
    For this, the device comprises an annular structure, intended to be linked to the upper opening of a manhole, a plurality of cylindrical bolts, 10 arranged orthogonally to an upper face of the annular structure, and a corresponding plurality of nuts of support and adjusting nuts linked to the plurality of bolts, preferably by threading. The annular structure in turn comprises a cylindrical ring, to one of whose longitudinal edges an annular crown is perpendicularly linked.
    fifteen
    The cylindrical ring comprises an inner opening of similar diameter to the inner diameter of the annular crown, both elements of the annular structure being linked together by welding. In turn, the cylindrical bolts are linked by welding to the annular crown, with its axis located orthogonally with respect to the surface 20 thereof.
    In a preferred embodiment, all these elements of the device are made of steel, and the annular structure is linked to the upper end of a frustoconical element located at the end of the manhole. Said preferred embodiment comprises eight 25 cylindrical bolts perpendicularly linked to the crown of the annular structure, and twenty-four nuts, three for each of the bolts, two being for support and one for adjustment.
    The leveling procedure at the site of registration mouths that uses the device 30 thus described comprises the following steps:
    - execution of a well in which a plurality of prefabricated rings are introduced successively, preferably in concrete, being crowned by a hollow conical structure, preferably also of concrete,
    - placement of the annular structure of the device, with welded bolts, on an upper face of hollow conical structure,
    - placing a pair of support nuts on each bolt,
    5
    - arrangement of a fence over the bolts, having previously made holes in the fence in accordance with the exact geometric arrangement of the bolts in the device. Said drill holes must have a diameter slightly larger than the diameter of the bolts, to facilitate fitting,
    10
    - placing an adjusting nut on each bolt, over the fence, leveling the fence with respect to the level of the final surface, and tightening the adjusting nuts,
    15 - solidifying the assembly with concrete,
    - execution of granular filling,
    - execution of the firm layers, and
    twenty
    - termination and placement of a closing cover of the manhole.
    The main advantages of this device, as well as the leveling procedure associated with it, lie first of all in that it allows you to place the fence and its cover
    25 at the desired height and the necessary inclination with high precision, in order to adapt to the level and slope of the surface flush, thanks to the use of nuts that move on threaded bolts, unlike what happens with prefabricated rings of concrete.
    30 Likewise, the union of the solid concrete with the steel bolts provides great resistance to the resulting assembly, and guarantees its durability against the loads to which the surface is subjected, especially in areas of road traffic, avoiding seats that can assume discomfort for traffic and added costs for repair.
    Another important advantage to note is that through the use of the device, the fence and the cover rest on the threaded bolts, which in turn rest on the annular structure that is placed on the conical concrete structure of the well. This means that the compression load received by the cover and its fence is transmitted directly to the concrete cone trunk 5 by means of the bolts, which have high compressive strength,
    This is a very structurally beneficial aspect, since the assembly formed by the concrete rings and the upper cone trunk have a high load resistance capacity. This reduces the risk of collapse of the fence and cover that exists in the usual construction solution of the log wells, in which the concrete poured in situ is responsible for holding the poured loads on the cover, which does not have a control of execution as rigorous as in the case of prefabricated elements, and therefore presents less resistance.
    15 Finally, it should be noted that it is a simple and efficient device, with a moderate cost and rapid commissioning, which therefore represents an advantageous solution since it guarantees long-term functionality.

    PREFERRED EMBODIMENT OF THE INVENTION
    Next, a detailed explanation of a preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.
    The leveling device for manhole covers described, shown in Figure 1, is formed by an annular structure (1), intended to be connected to an upper opening mouth (2) of a manhole, a plurality of cylindrical bolts (3), arranged perpendicularly to the annular structure (1), and a plurality of support nuts (4) linked to bolts (3) for leveling a fence (5) on which a cover is arranged (6) opening of the manhole.
    The annular structure (1) in turn comprises a cylindrical ring (7) and an annular crown (8) that perpendicularly part of the cylindrical ring (7), as seen in Figure 1. The cylindrical ring (7) has an opening inside with a diameter similar to the inner diameter of the annular crown (8).
    5
    The bolts (3), which in this preferred embodiment are eight in total, are perpendicularly linked to the annular crown (8), distributed evenly throughout the length of said crown, that is, every 45 °. The cylindrical ring (7), the annular crown (8) and the bolts (3) are made of steel and are linked together by welding.
    10
    Each of the bolts (3) also comprises a threaded side surface, to which the support nuts (4) are linked by threading. It is envisaged that two support nuts (4) are linked to each of the bolts (3).
    15 The arrangement of the support nuts (4) along the bolts (3) defines the inclination and height with which the fence (5) is to be positioned, since said fence (5) rests superiorly on the support nuts (4). For this, the fence (5) comprises a plurality of through holes defined in its longitudinal edge, through which the bolts (3) are introduced until they meet the support nuts (4). These holes
    20 fence passers (5) must have a slightly larger diameter than the bolts (3) to facilitate the fit between both elements. Finally, adjusting nuts (9) are threadedly linked to the upper end of each of the bolts (3) until they meet the fence (5), to fix the joint between the fence (5) and the device.
    25 The leveling procedure in the field of manhole covers using the device described above comprises a first stage, shown in Figure 2, in which a well is executed in the ground, a well in which a successively introduced plurality of prefabricated concrete rings (10) as a hollow column, said column being topped by a hollow conical structure
    30 (11), also of concrete, at whose upper end the opening mouth is defined
    upper (2) of the manhole.
    In a second stage, shown in Figure 3, the annular structure (1) of the device is arranged, with the bolts (3) attached thereto, on an upper structure face
    hollow conical trunk (11). The third stage, illustrated in Figure 4, comprises the threading of the support nuts (4) in the bolts (3), two support nuts (4) being arranged in each bolt (3) so that said nuts of support (4) define a plane with an inclination similar to that desired to be granted to the 5 fence (5) and the cover (6).
    The fourth stage, shown in Figure 5, comprises the arrangement of the fence (5) on the device, so that the bolts (3) pass through the plurality of through holes defined in the outer longitudinal edge of the fence (5) until it encounters 10 support nuts (4). In this way, the fence (5) is positioned with the necessary inclination. Once this inclination is obtained, the respective adjusting nuts (9) are introduced in each of the bolts (3), as can be seen in Figure 6, the leveling of the fence (5) is carried out with respect to the surface flush end, and tighten the adjusting nuts (9).
    fifteen
    Finally it remains to proceed to the solidification of the assembly formed by the fence (5) and the device with concrete, as illustrated in Figure 7, the execution of the granular filling, as seen in Figure 8, the execution of the layers of firm, shown in figure 9 and the termination and arrangement of the cover (6) for closing the manhole on the fence 20 (5).
