Problems solved by technology

As the height difference between the well base and the road surface increases, the manhole cover is more and more impacted by the impact and vibration of the car, and the well base sinks at an accelerated rate, resulting in damage to the well cover and loose, cracked, and subsidence of the road around the well base, so that the well base must be replaced. Restoring sunken pavement
[0003] Problems such as manhole cover sinking and surrounding damage have become bottlenecks restricting the quality of urban road engineering, seriously affecting urban road traffic safety and service levels, and affecting the smoothness and beauty of roads

Embodiment 1

[0026] When the periphery of the old manhole cover is slightly damaged and the foundation is good, a method for replacing the anti-settling manhole cover includes the following steps:

[0027] a. Take out the old manhole cover;

[0028] b. Take the old manhole cover as the center, directly set out the line according to the 1.0m, cut and remove the periphery of the inspection well to the standard width, and control the depth at 12~15cm;

[0029] c. Clean the surface of the base of the manhole cover, calculate the volume to be filled, estimate the amount of epoxy asphalt mixture, and then use liquid epoxy asphalt: AC10 grade ingredients (material is limestone) as 1: (5~6) in the vertical Fully mix the two in a forced mixer for 1 to 3 minutes for use, and finally use part of the epoxy asphalt mixture to level the base of the manhole cover;

[0030] d. Place the manhole cover adjustment ring;

[0031] e. Install the leak-proof pot;

[0032] F. Fill the well-mixed epoxy asphalt ...

Embodiment 2

[0038] When there is serious damage around the old manhole cover and the base is not good, a method for replacing the anti-settling manhole cover includes the following steps:

[0039] a. Take out the old manhole cover;

[0040] b. Take the old manhole cover as the center, set out the line according to the actual damaged range, cut and remove the periphery of the inspection well to the standard width, and excavate the depth according to the actual situation. If the depth exceeds 15cm, cement brick masonry should be used to ensure that the depth is 12~15cm;

[0041] c. Clean the surface of the base of the manhole cover, calculate the volume to be filled, estimate the amount of epoxy asphalt mixture, and then use liquid epoxy asphalt: AC13 grade ingredients (basalt) as 1: (5~6) in the vertical Fully mix the two in a forced mixer for 1 to 3 minutes for use, and finally use part of the epoxy asphalt mixture to level the base of the manhole cover;

[0042] d. Place the manhole co...

Abstract

The invention discloses an installation method for an anti-sedimentation well cover, and belongs to the technical field of municipal engineering. The installation method comprises the following steps that a. an old well cover is taken out; b. setting out is carried out, and the periphery of an inspection well is cut and broken to a standard width and a standard depth; c. a base of the well cover is leveled; d. a well cover adjustment ring is placed; e. an anti-leakage pot is inserted; f. epoxy asphalt mixed materials are input and compacted layer by layer; g. epoxy asphalt mixed materials are input again to be higher than the original road surface by 1-2 cm, and the anti-leakage pot is pulled out; h. the anti-sedimentation well cover is inserted and pressed into the road surface to be flush with the road surface; i. water sealing is carried out on an overlay. The installation method for the anti-sedimentation well cover is easy to operate, is easy to implement, is low in equipment requirement, has the advantages of being high in strength, durable, practical, low in price and the like, and has popularization value in the daily maintenance of urban roads.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering and relates to a replacement method for an anti-settling manhole cover. Background technique [0002] With the rapid increase of urban traffic volume, settlement, cracking, jumping while driving, noise and other phenomena often occur around urban road inspection wells and manhole covers. At present, manhole cover sinking has become a common problem in many cities in my country. The main reason for the analysis is that the well base is pre-buried, and it is not easy to accurately determine the elevation. When adjusting the height difference between the well base elevation and the road surface by a few centimeters, the construction workers often fill it with stones, tiles and other materials at will. After the manhole cover is installed, these filling materials are easily crushed under the impact and vibration of the vehicle. With the infiltration of rainwater around the well base, t...
