Problems solved by technology
[0002] The currently widely used inspection wells built with solid clay bricks have low strength and high water permeability. After a period of use, the skin falls off and the inside becomes loose, resulting in the overall sinking of the well body and the settlement of the surrounding road surface, which has become a common problem in road engineering. The potential safety hazards caused by this, the accidents of inspecting wells to injure people and damage vehicles occur from time to time
[0003] In addition, cement pressed bricks are similar to clay bricks, which are not strong enough and have poor connection. However, the prefabricated inspection well has a relatively heavy weight and is difficult to assemble. It needs to be installed with a crane, which is troublesome.

Embodiment Construction
[0030] The present invention will be further described below in conjunction with accompanying drawing:
[0031] Such as Figure 1 to Figure 5
[0032] The construction process is as follows:
[0033] 1. Prefabricated reinforced concrete anti-settling concrete cover plate, with dimensions ranging from 1000×1000×200mm to 2000×2000×200mm, which can be manufactured according to the actual situation. The revision center reserves the size of the manhole cover according to the specifications of the manhole cover installed. Taking the straw hat type manhole cover of model DN650 as an example, the reinforced concrete anti-settling concrete cover plate is as follows: figure 1 shown.
[0034] 2. Cut the road surface, take the well chamber as the center, cut the road surface according to the size of the reinforced concrete anti-settling concrete cover plate, increase the length of each side by 200mm, pay attention to the neatness of the road surface cutting, remove the original well co...

An anti-sedimentation inspection well replacement process is characterized by including the following steps that firstly, an anti-sedimentation concrete cover plate (1) is prefabricated, wherein the anti-sedimentation concrete cover plate (1) is of a reinforced concrete structure; and secondly, road cutting is conducted, wherein road cutting is conducted with a well chamber as the center according to the rule that the length of each side of the anti-sedimentation concrete cover plate (1) is increased by 200 mm, an existing well lid frame is removed, and chiseling is conducted on the periphery. The anti-sedimentation inspection well replacement process is easy to construct, time is saved, operation is convenient, the influence on traffic flow is small, and the anti-sedimentation inspection well replacement process can be suitable for old well lid replacement of vast urban and rural areas.
Description
technical field [0001] The invention relates to the technical field of well cover construction, in particular to an anti-subsidence inspection well replacement process. Background technique [0002] The currently widely used inspection wells built with solid clay bricks have low strength and high water permeability. After a period of use, the skin falls off and the inside becomes loose, resulting in the overall sinking of the well body and the settlement of the surrounding road surface, which has become a common problem in road engineering. The potential safety hazard that this produces, the accident that inspection well injures people, damages vehicle happens from time to time. [0003] In addition, cement-pressed bricks are similar to clay bricks, which are not as strong as they are and have poor connectivity. Assembled inspection wells are heavy in weight and difficult to assemble. They need to be installed with a crane, which is troublesome. Contents of the invention ...
