Technical Field

[0001] The utility model relates to a building structure, in particular to a module well cover plate, specifically a module well prefabricated waterproof cover plate. Background Art

[0002] Inspection well module is also called modular inspection well, well wall brick, masonry inspection well, masonry well module, etc. It is the most common inspection well in the construction industry and infrastructure industry. The inspection well module is commonly used. It has many characteristics and advantages, such as high strength, strong pressure resistance, corrosion resistance, beautiful and practical, etc. It is also energy-saving and environmentally friendly, simple in construction, convenient and fast, labor-saving and material-saving, and easy to install. Inspection well module is widely used as a new type of masonry material in construction projects such as electricity, water conservancy, urban municipal administration, sponge city, etc. And the state department recommends actively promoting and recommending wide application.

[0003] The diameter of the inspection well module is usually relatively large, and conventional manhole covers cannot be used directly. Therefore, a cover plate with a through hole is set on the well chamber of the inspection well module, and the aperture of the through hole is equivalent to that of a conventional manhole cover. Then, a well shaft is built around the through hole on the cover plate, and a conventional manhole cover is used to cover the well shaft.

[0004] At present, the traditional cover plate is a concrete flat plate, which is easy to form a through seam at the connection with the module well, which is very likely to cause water leakage, seriously affecting the use function of the pipeline, and easily causing soil erosion around the well and ground subsidence.

[0005] Therefore, it is urgently needed to be improved in order to better meet the market demand. Utility Model Content

[0006] The purpose of the utility model is to provide a prefabricated waterproof cover plate for a modular well in view of the deficiencies in the prior art, which can effectively eliminate water leakage while meeting structural requirements and fully meet market demand.

[0007] The technical solution of the utility model is:

[0008] A prefabricated waterproof cover plate for a modular well, comprising a main body, which is disc-shaped and has a through hole thereon, and a downwardly protruding cover edge at its edge; a first annular groove is provided around the through hole; the first groove is concentric with the through hole; a second annular groove is provided on the inner side wall of the cover edge; a third annular groove is provided on the bottom surface of the main body; the third groove is concentric with the main body, and the distance between the third groove and the inner wall of the cover edge is 7-8 cm; water-swelling waterproofing strips are respectively provided in the first groove, the second groove and the third groove.

[0009] Furthermore, the through hole is eccentrically arranged relative to the body.

[0010] Furthermore, the height of the cover edge is 10 cm.

[0011] Furthermore, the distance between the first groove and the edge of the through hole is 7-8 cm.

[0012] Furthermore, the second groove is parallel to the body.

[0013] Furthermore, the second groove is located in the middle of the cover edge.

[0014] Beneficial effects of the utility model:

[0015] The utility model has reasonable design, simple structure and convenient use, and can not only meet the structural requirements of the module well, but also effectively eliminate water leakage, ensure the normal use of the module well, and fully meet the market demand.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 shown.

[0022] The utility model discloses a prefabricated waterproof cover plate for a module well, which comprises a main body 1.

[0023] The body 1 is disc-shaped, with a through hole 2, and a downwardly protruding cover edge 6 at its edge. The cover edge 6 is about 10 cm high and is convenient for clamping at the upper end of the well chamber 8. The body 1 and the cover edge 6 are concrete structures and can be cast in one piece.

[0024] The through hole 2 is eccentrically arranged relative to the body to meet the design requirements. At the same time, a first annular groove 3 is arranged around the through hole 2. The first groove 3 is concentric with the through hole 2 and is 7-8 cm away from the edge of the through hole 2.

[0025] An annular second groove 5 is provided on the inner side wall of the cover edge 6. The second groove 5 is parallel to the body 1 and is located in the middle of the cover edge 6.

[0026] The bottom surface of the body 1 is provided with an annular third groove 4. The third groove 4 is concentric with the body 1, and the distance between the third groove 4 and the inner wall of the cover edge 6 is 7-8 cm.

[0027] The first groove 3, the second groove 5 and the third groove 4 are respectively provided with water-swellable waterproofing strips 9. The water-swellable waterproofing strips are conventional commercial products and are adapted to the first groove, the second groove and the third groove so that they can be firmly installed.

[0028] During construction, first prefabricate the main body according to the design requirements. The main body 1 is installed on the upper end of the well chamber 8, and the cover edge 6 is clamped on the outer wall of the upper end of the well chamber 8, so that the water-swellable waterproofing strip 9 in the second groove 5 and the third groove 4 are tightly fitted with the outer wall of the upper end of the well chamber 8 and the end face of the upper end of the well chamber 8 respectively, which can eliminate the gap between the main body 1 and the well chamber 8 and prevent external water from leaking into the well chamber. Then, the well shaft 7 is built on the top surface of the main body 1 around the through hole 2. The wall thickness of the well shaft 7 is about 18 cm, so that the water-swellable waterproofing strip in the first groove 3 is located in the middle position of the lower end face of the well shaft 7 and is close to the lower end face of the well shaft 7, so that the gap between the well shaft 7 and the main body 1 can be eliminated, preventing external water from flowing into the through hole and falling into the well chamber.

[0029] Therefore, the utility model completely solves the problem of easy leakage of module wells in the past, ensures the normal use of the module wells, and fully meets market demand.

[0030] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
