Problems solved by technology
Just because they are located in the main lane, it has the following effects on road quality: 1. It directly affects the use function of urban roads and the beauty of the urban environment, which hinders the view of the city; 2. It directly affects the traffic safety of the city, causing Accelerate the damage of motor vehicles and non-motor vehicle parts, and even cause traffic accidents in serious cases, affecting the smooth flow of traffic
The main reason is that the construction managers or operators misoperate during the construction process, the design drawings are not perfect and other factors cause construction defects, resulting in subsidence around the inspection well and local subsidence

Embodiment Construction
[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0025] see figure 1 , figure 2 , image 3 with Figure 4 , a construction method for preventing surrounding and local subsidence of road surface inspection wells, comprising the following construction steps:
[0026] a, excavation trench:
[0027] The groove of the inspection well shall be excavated synchronously with the pipeline groove, and the excavation section shall meet the requirements of the approved construction plan. The undisturbed foundation soil at the bottom of the tank must not be disturbed. During mechanical excavation, a 20-30cm soil layer is reserved at the bottom of the tank to be manually excavated to the design elevation...

Abstract
The invention discloses a construction method for preventing peripheral and local sedimentation of a road surface inspection well, which comprises the following steps: a, excavating a groove; b, constructing a prefabricated reinforced concrete floor of an inspection well base; c, constructing a well chamber and a well cylinder of the inspection well, d, constructing a well periphery cast-in-place reinforced concrete unloading plate, excavating backfilled materials on the periphery of the inspection well, arranging a double-layer two-way reinforced mesh framework and casting concrete, e, well seat location installation: laying lower-layer asphalt, placing a steel plate between the well seat and the reinforced concrete unloading plate and installing the well seat and a well cover, and f, constructing an asphalt upper-layer. By means of the mode, the construction method for preventing peripheral and local sedimentation of the road surface inspection well is capable of avoiding peripheral and local sedimentation of most inspection wells, is simple in construction method and low in cost, avoids the problem of repeated construction in urban roads to the largest extent and meets requirements for national energy-saving, emission reduction and environment-friendly building.
Description
technical field [0001] The invention relates to the field of inspection well construction, in particular to a construction method for preventing peripheral and local subsidence of road surface inspection wells. Background technique [0002] Urban roads are the main artery of urban survival and development. In order to ensure the normal operation of the city and save land resources, various urban public pipelines are often laid under urban roads, such as water supply and drainage, heat, gas, communication, power supply pipe networks, etc. Therefore, there are many inspection wells for various types of pipe networks on urban roads. The existence of these inspection wells adds many unfavorable factors to the construction of road engineering. If they are not handled properly, road pavement will sink, crack, Damage, excessive height difference between the well frame and the road surface, subsidence, damage, and displacement and fall of the manhole cover around the inspection well...
