Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water supply and drainage, and in particular relates to an anti-collapse rainwater collection manhole cover reinforcement structure used in urban roads. Background Art
[0002] Rainwater collection wells are an important part of the municipal drainage system. They are usually set up on the side of roads and in low-lying areas. As a facility for collecting surface water in the pipeline drainage system, they are generally composed of rainwater covers, well bodies, and water collection branches. By collecting and guiding rainwater into underground pipes, the smooth discharge of rainwater is ensured to avoid urban waterlogging that affects traffic or damages the road surface.
[0003] In the existing urban drainage system, rainwater covers often collapse and fall due to factors such as material aging, vehicle crushing, and natural disasters. Among them, damage to the support of the rainwater cover is one of the main reasons for collapse and falling. The support is the key part where the rainwater cover contacts the well body, and needs to directly or indirectly bear the external stress of vehicle loads and rainwater erosion. Due to its small stress area, unreasonable design, and improper construction, the support is prone to damage, which in turn leads to the collapse and fall of the rainwater cover, causing damage to the road surface and posing a safety hazard. Utility Model Content
[0004] In order to improve the stability of the rainwater cover and prevent the rainwater cover from collapsing and falling, the utility model proposes an anti-collapse rainwater cover reinforcement structure.
[0005] A collapse-proof rainwater cover reinforcement structure is arranged on a rainwater collection well, and is characterized in that it includes a reinforcing plate, a corner reinforcing piece and a shock-absorbing gasket, wherein the reinforcing plate is arranged on the top of the collection well body, and the shape of the reinforcing plate matches the shape of the collection well, and the length and width of the reinforcing plate are both greater than the length and width of the top of the collection well; the corner reinforcing pieces are placed at the four corners of the reinforcing plate and correspond to the positions of the four corners of the collection well, and the reinforcing plate is clamped on the collection well by the corner reinforcing pieces; holes corresponding to the positions are arranged on the rainwater cover, the corner reinforcing piece and the reinforcing plate; the rainwater cover is arranged on the top surface of the reinforcing plate and is fixed by inserting rods through the holes; a number of shock-absorbing pad grooves are arranged on the top surface of the reinforcing plate, and shock-absorbing gaskets corresponding to the number and positions of the shock-absorbing pad grooves are arranged on the bottom surface of the rainwater cover, and the shock-absorbing gaskets are symmetrically arranged; a mortar layer is filled between the reinforcing plate and the rainwater cover.
[0006] Furthermore, the reinforcing plate is cast with C30 concrete, with a casting thickness of 10 cm, and its edge extends 20 cm outward from the top edge of the collection well.
[0007] Furthermore, the inserted rod is made of HRB400 grade steel bars, and the length of the inserted rod is sufficient to achieve a horizontal fixing effect on the rainwater cover.
[0008] Furthermore, the corner reinforcement piece is made of a Q235B high-strength steel plate with a thickness of 5 mm, holes are drilled at the corners, and a channel is reserved for the insertion rod to pass through. The corner reinforcement piece is cast together with the reinforcement plate.
[0009] Furthermore, the shock-absorbing gaskets are made of rubber material, and are arranged around the reinforcing plate, with four shock-absorbing gaskets arranged on each of the left and right sides, and one shock-absorbing gasket arranged on each of the upper and lower sides.
[0010] The utility model is effective in that: the rainwater cover provides a high-strength support to reduce the risk of damage to the support, the corner reinforcement further strengthens the strength of the support of the rainwater cover, and fixes the rainwater cover to prevent displacement and sliding, and the shock-absorbing gasket provides a shock-absorbing and buffering effect for the rainwater cover to avoid the rigid deformation of the rainwater cover causing the cover to break. By setting the reinforcement plate and the corner reinforcement, not only the stability of the rainwater cover is enhanced, but also the weak links of the support are strengthened; in addition, the shock-absorbing gasket reduces the damage to the edge of the rainwater outlet caused by the external stress of vehicle load and rainwater scouring directly or indirectly, which can effectively prevent the collapse of the base edge and the collapse of the rainwater cover caused by the displacement of the rainwater cover. The reinforced rainwater cover can meet the normal operation requirements of the urban drainage system. BRIEF DESCRIPTION OF THE DRAWINGS
