Description

Technical Field

[0001] This utility model belongs to the field of highway technology, and in particular relates to a structure for preventing settlement of highway drainage wells. Background Technology

[0002] Highway drainage wells are mainly used to collect and drain rainwater and snowmelt from highway surfaces. When it rains or snow melts, water accumulates on the road surface. Through their openings and connected drainage pipes, the drainage wells allow the water to quickly converge and drain into the underground drainage network, preventing water accumulation from affecting normal vehicle driving, ensuring traffic safety, and also reducing the risk of long-term damage to the highway surface structure caused by water accumulation.

[0003] When roadside manholes settle, the manhole cover becomes lower than the road surface, forming a pit. The settlement of the manhole shaft alters the original drainage structure, such as the slope, making water flow and drainage less smooth and prone to water accumulation. To improve the anti-settlement effect of manholes, we designed an anti-settlement structure for roadside manholes. The bottom of the manhole is supported by multiple trapezoidal frames, increasing the support area at the bottom of the manhole and reducing the possibility of settlement. Utility Model Content

[0004] The purpose of this utility model is to provide a road manhole anti-settlement structure, which has the advantages of increasing the support area of ​​the manhole bottom by multiple trapezoidal frames, thereby reducing the possibility of manhole settlement and solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A road sewer anti-settlement structure includes a hoop installed at the bottom of the surface of the sewer body. Fastening components are provided at both ends of the hoop. The hoop is fixedly installed on the surface of the sewer body by the fastening components. Multiple hollow support seats are arranged in a ring array on the surface of the hoop. An installation component is provided between the hollow support seats and the hoop. The installation component includes a connecting plate welded to the surface of the hoop. Two symmetrical sleeve plates are fixedly connected to the top of the hollow support seats. The two sleeve plates are sleeved on the surface of the connecting plate. A sleeve shell is sleeved on the side of the connecting plate away from the hoop. Two symmetrical screws are provided through the sleeve shell. The screws pass through the sleeve shell and are threadedly connected to the connecting plate.

[0006] Preferably, positioning grooves are provided on both sides of the connecting plate, and positioning strips that are adapted to the positioning grooves are provided on the opposite side of the two sleeve plates.

[0007] Preferably, the hollow support base is hollow and trapezoidal in shape.

[0008] Preferably, the bottom of the casing is open, and the bottom of the casing is in contact with the hollow support base.

[0009] Preferably, the fastening assembly includes ear plates fixedly connected to both ends of the hoop, one side of the ear plate is provided with a notch, the inner cavity of the two notches is provided with a screw rod, and both ends of the surface of the screw rod are threadedly connected with nuts that abut against the side of the ear plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a fastening assembly to install the hoop on the bottom of the sewer body. Then, multiple hollow support seats are installed on the surface of the hoop using an installation assembly. The bottom of the hollow support seats is flush with the bottom of the sewer body. The cooperation of multiple hollow support seats increases the support area at the bottom of the sewer body. This achieves the purpose of increasing the support area at the bottom of the sewer body by using multiple trapezoidal frames to assist in the support of the sewer body, thereby reducing the possibility of sewer body settlement.

[0012] 2. By using the positioning groove and positioning strip in combination, when the sleeve plate is installed on the surface of the connecting plate, the positioning strip will enter the inner cavity of the positioning groove, which restricts the sleeve plate from moving downward and slipping off the connecting plate, thus ensuring the stability of the hollow support seat.

[0021] In the following description, embodiments of the anti-settlement structure for highway drainage wells of this utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates an embodiment of a road manhole anti-settlement structure, comprising a hoop 2 installed at the bottom of the surface of the manhole body 1. Fastening components 4 are provided at both ends of the hoop 2. Each fastening component 4 includes ear plates 41 fixedly connected to both ends of the hoop 2. A notch 42 is formed on one side of each ear plate 41, and a screw rod 43 is provided within the inner cavity of each notch 42. Nuts 44, which abut against the sides of the ear plates 41, are threaded to both ends of the screw rod 43. The hoop 2 is fixedly installed on the surface of the manhole body 1 via the fastening components 4. Multiple hollow support seats 3 are arranged in a circular array on the surface of the hoop 2. The hollow support seats 3 are hollow trapezoids. An installation component 5 is provided between the hollow support seats 3 and the hoop 2. The installation component 5 includes a connecting plate 51 welded to the surface of the hoop 2. The top of the hollow support seats 3 is fixed... The fixed connection has two symmetrical sleeve plates 52, which are fitted onto the surface of the connecting plate 51. A sleeve shell 53 is fitted onto the surface of the connecting plate 51 away from the hoop 2. Two symmetrical screws 54 are threaded through the sleeve shell 53 and connected to the connecting plate 51. Positioning grooves 55 are provided on both sides of the connecting plate 51. Positioning strips 56 that are adapted to the positioning grooves 55 are provided on the opposite side of the two sleeve plates 52. The bottom of the sleeve shell 53 is open and contacts the hollow support 3. Through the cooperation of the positioning grooves 55 and the positioning strips 56, when the sleeve plate 52 is installed on the surface of the connecting plate 51, the positioning strips 56 will enter the inner cavity of the positioning grooves 55, which restricts the downward movement of the sleeve plate 52 and prevents it from sliding off the connecting plate 51, thus ensuring the stability of the hollow support 3.

[0023] Working principle: When using this utility model, the hoop 2 is placed on the bottom of the surface of the drain body 1. The screw rod 43 is inserted into the inner cavity of the notch 42 on the two ear plates 41. Then, the nut 44 is tightened until the hoop 2 is firmly fixed on the surface of the drain body 1. The hollow support base 3 is lifted so that the two sleeve plates 52 on the hollow support base 3 are fitted onto the surface of the hoop 2 due to the cooperation of the positioning strip 56 and the positioning groove 55. Then, the sleeve shell 53 is lifted and fitted onto the end of the connecting plate 51 and the screw 54 is inserted to tighten it. Multiple hollow support bases 3 can be installed on the surface of the hoop 2. The bottom of the hollow support base 3 should be flush with the bottom of the drain body 1. The cooperation of multiple hollow support bases 3 increases the support area of ​​the bottom of the drain body 1, effectively increasing the anti-settlement effect of the drain body 1.

[0024] In summary, the anti-settlement structure for highway manholes uses a fastening assembly 4 to install the hoop 2 onto the bottom of the manhole body 1. Then, multiple hollow support seats 3 are installed onto the surface of the hoop 2 using an installation assembly 5. The bottom of the hollow support seats 3 should be flush with the bottom of the manhole body 1. The combination of multiple hollow support seats 3 increases the support area at the bottom of the manhole body 1, thus achieving the goal of increasing the support area at the bottom of the manhole and reducing the possibility of settlement.
