Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers and bases, in particular to a quick-installation type municipal manhole cover and base. Background Technique

[0002] At present, during the installation of manhole covers and bases, a drainage channel is opened on the road surface, and then the base is prepared from the channel. After the base is prepared, the manhole cover is installed. In this way, on the one hand, due to the small space of the opened drainage channel, the construction difficulty in the drainage channel is large, and the overall quality of the prepared base is difficult to control. During later use, due to quality problems, it is easy to cause the sinking phenomenon at the position of the manhole cover and base, and maintenance operations need to be carried out after a period of time, and even re-production is required. On the other hand, the overall installation time of the manhole cover and base is long, and during the on-site production process, relatively large noise pollution will also be generated. The actual application effect of this preparation method is not good;

[0003] In addition, in the way of prefabricated bases, it is easy to occur that the bottom of the concrete layer is difficult to level, so that the finally formed manhole cover and base are prone to unevenness, and the later use effect is not good. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a quick-installation type municipal manhole cover and base.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A quick-installation type municipal manhole cover and base, including a base body, a manhole cover body, a concrete layer and a base installation groove. The base body, the manhole cover body and the concrete layer are prefabricated. The manhole cover body covers the base body, and the base body is inserted into the interior of the concrete layer;

[0007] Step-shaped grooves are symmetrically opened on both sides of the bottom of the concrete layer. The base installation groove is opened at the road surface position where the manhole cover needs to be installed. The whole composed of the base body and the concrete layer is arranged in the base installation groove. A first gap is left between the whole composed of the base body and the concrete layer and the bottom of the base installation groove, and a steel fiber layer is filled in the first gap;

[0008] The narrowest surface at the bottom of the concrete layer contacts the steel fiber layer, and the concrete layer moves horizontally to adjust the contact area between the concrete layer and the steel fiber layer, so as to adjust the horizontal plane at the top of the concrete layer.

[0009] Preferably, the concrete layer is arranged in a two-layer split structure, the concrete layer is separated near the bottom, and the height of the lower layer of the concrete layer is less than the height of the upper layer of the concrete layer.

[0010] Preferably, a plurality of bumps are evenly arranged on the top of the lower layer of the concrete layer, and notches for connecting the bumps are formed at the bottom of the lower layer of the concrete layer.

[0011] Preferably, a second gap is left between the integral formed by the well seat body and the concrete layer and the side of the well seat installation groove, and an asphalt layer is filled in the second gap.

[0012] Preferably, the thickness of the steel fiber layer is set to 4-6 cm.

[0013] Preferably, when the road surface is in an inclined state, the well seat body and the manhole cover body are in plane contact, the upper parts of the well seat body and the manhole cover body are both in an inclined state, and the manhole cover body and the road surface are in the same plane.

[0014] Preferably, when the road surface is in a flat state, the well seat body and the manhole cover body are in plane contact, the upper parts of the well seat body and the manhole cover body are both in a flat state, and the manhole cover body and the road surface are in the same plane.

[0015] Preferably, the bottom surface of the integral formed by the well seat body and the concrete layer is in horizontal contact with the top surface of the steel fiber layer.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By means of prefabricating the well seat and the manhole cover, on the one hand, the quality of the well seat and the manhole cover can be controlled, and the structural strength during the later use of the well seat and the manhole cover can be maintained. On the other hand, according to actual needs, well seats and manhole covers of appropriate sizes can be prepared, and no mismatching phenomenon will occur. At the same time, the preparation difficulty of the well seat, the manhole cover and the concrete layer is reduced, and they can be prepared in the factory, and no large noise will be generated during on-site assembly;

[0018] 2. A stepped groove is arranged at the bottom of the concrete layer. When installing the concrete layer, the concrete layer can be moved. The contact area between the bottom of the concrete layer and the steel fiber layer is small, and the steel fiber layer is not completely solidified. The moving concrete layer can better contact and limit with the steel fiber layer, which is convenient for leveling the well seat and the manhole cover. Finally, the position of the installed well seat and manhole cover is more stable, and the actual application effect is better. Description of the Drawings

[0027] It is easily understood that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various interchangeable structural ways and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0028] As Figure 1-2 shown, a quick - installation type municipal well seat cover includes a well seat body 10, a well cover body 20, a concrete layer 30 and a well seat installation groove 60. The well seat body 10, the well cover body 20 and the concrete layer 30 are pre - formed. The well cover body 20 covers the well seat body 10, and the well seat body 10 is inserted into the interior of the concrete layer 30;

[0029] Stepped grooves 32 are symmetrically opened on both sides of the bottom of the concrete layer 30. The well seat installation groove 60 is opened at the road surface position where the well cover needs to be installed. The whole composed of the well seat body 10 and the concrete layer 30 is arranged in the well seat installation groove 60. There is a first gap between the whole composed of the well seat body 10 and the concrete layer 30 and the bottom of the well seat installation groove 60, and a steel fiber layer 50 is filled in the first gap;

[0030] The narrowest surface at the bottom of the concrete layer 30 contacts the steel fiber layer 50. The concrete layer 30 moves horizontally to adjust the contact area between the concrete layer 30 and the steel fiber layer 50, and the horizontal plane at the top of the concrete layer 30 is adjusted;

[0031] There is a second gap between the integral formed by the manhole base body 10 and the concrete layer 30 and the side of the manhole base installation groove 60, and an asphalt layer 40 is filled in the second gap.

[0032] Specifically, the manhole base body 10, the manhole cover body 20 and the concrete layer 30 are prefabricated. When installing the manhole cover and manhole base on the road surface, a manhole base installation groove 60 is opened on the road surface, and the diameter of the manhole base installation groove 60 is larger than the diameter of the integral formed by the manhole base body 10 and the concrete layer 30 combined;

[0033] After the manhole base installation groove 60 is opened, steel fiber concrete is filled at the bottom of the manhole base installation groove 60. When the steel fiber concrete is cured to 90%, the integral formed by the manhole base body 10 and the concrete layer 30 is placed inside the manhole base installation groove 60. The user shakes the integral formed by the manhole base body 10 and the concrete layer 30. Since the bottom of the concrete layer 30 is set as a stepped structure, the bottom of the concrete layer 30 can quickly push the steel fiber layer 50 until the fit between the steel fiber layer 50 and the concrete layer 30 reaches the best state, making the position of the concrete layer 30 on the steel fiber layer 50 more stable, and leveling the top of the manhole cover body 20 placed on the manhole base body 10;

[0034] After the manhole cover body 20 is leveled, hot asphalt is filled in the gap between the side of the concrete layer 30 and the manhole base installation groove 60, and the gap between the concrete layer 30 and the manhole base installation groove 60 is filled with hot asphalt. After cooling, an asphalt layer 40 is formed. Through the setting of the asphalt layer 40, on the one hand, the gap can be filled, and on the other hand, it can play an adhesive role, making the position of the installed manhole base and manhole cover more stable;

[0035] A mixed layer 31 formed by the asphalt layer 40 and the steel fiber layer 50 will be formed in the stepped groove 32 at the bottom of the concrete layer 30. Through the mixed layer 31, the space in the stepped groove 32 can be filled, so that the position of the finally placed concrete layer 30 is more stable;

[0036] Through the construction method, the installation speed of the manhole base and manhole cover is fast, the position of the concrete layer 30 after placement is stable, and finally the position of the manhole base and manhole cover is stable, and the actual application effect is good; the manhole base, manhole cover and concrete layer 30 are prefabricated, and their structural strength is convenient to be adjusted during manufacturing, with higher structural stability and longer service life.

[0037] Such as Figure 3As shown, the concrete layer 30 is arranged in a two-layer split structure. The concrete layer 30 is separated near the bottom. The height of the lower layer of the concrete layer 30 is less than that of the upper layer of the concrete layer 30. When the concrete layer 30 is installed, the lower layer of the concrete layer 30 can be installed first. Due to its small volume and light weight, it is convenient for users to finely adjust the position of the lower layer of the concrete layer 30, making the overall stability of the finally formed concrete layer 30 higher after installation and the actual application effect better.

[0038] As Figure 4 shown, a plurality of bumps 33 are evenly arranged on the top of the lower layer of the concrete layer 30, and notches connecting the bumps 33 are formed at the bottom of the lower layer of the concrete layer 30. Through this structural arrangement, the connection position between the upper layer and the lower layer of the concrete layer 30 can be made more stable, and no shaking phenomenon will occur during use, and the actual application effect is better.

[0039] The thickness of the steel fiber layer 50 is set to 4 - 6 cm. Through this thickness setting of the steel fiber layer 50, it is not necessary to fill a relatively thick steel fiber layer 50. While saving materials, the overall strength of the steel fiber layer 50 can be maintained, and the supporting effect on the well seat body 10 is better, maintaining the position stability of the well seat body 10.

[0040] As Figure 5-6 shown, when the road surface is in an inclined state, the well seat body 10 and the manhole cover body 20 are in plane contact. Through this structural arrangement, the well seat body 10 can be kept in a vertical state, and the downward pressure direction of the well seat body 10 is consistent with the gravity direction. During the installation process of the well seat body 10, no position deviation will occur;

[0041] Both the upper parts of the well seat body 10 and the manhole cover body 20 are in an inclined state, the manhole cover body 20 and the road surface are in the same plane, and the connection position between the well seat body 10 and the manhole cover body 20 is stable, and the later use effect of the well seat and the manhole cover is better.

[0042] As Figure 1-2 shown, when the road surface is in a flat state, the well seat body 10 and the manhole cover body 20 are in plane contact, both the upper parts of the well seat body 10 and the manhole cover body 20 are in a flat state, and the manhole cover body 20 and the road surface are in the same plane;

[0043] It can make the installation position of the well seat body 10 stable, and the pressure directions of the manhole cover body 20 and the well seat body 10 are always in the same vertical direction and consistent with the gravity direction, so that the well seat body 10 and the manhole cover body 20 will never have a position deviation.

[0044] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications shall fall within the protection scope of the present utility model.
