Problems solved by technology

[0002] At present, the urban entrance and exit roads are mainly heavy-duty traffic roads. Most of the drainage inspection wells in the roads are constructed according to the national building standard atlas "Municipal Drainage Pipeline Engineering and Auxiliary Facilities" (06MS201). After the roads are put into use, some inspection wells have subsided cracks, uneven settlement and other diseases on the surrounding road surface, which have a negative impact on the appearance of the road and driving comfort, and even have a negative impact on the image of the city

Embodiment 1

[0039] An inspection well installation and construction process, comprising the following steps:

[0040] (1) Water stability of paved subbase

[0041] a. Before paving the water stability of the subbase, build a reinforcement layer 2 on the outer wall of the well circle 1, build the reinforcement layer to the top elevation of the water stability 3 of the subbase, and cover and close the inner wall opening of the well circle with a precast concrete temporary cover , to prevent the water from falling into the well when the paving water is stable;

[0042] b. Carry out water-stabilized paving of the subbase at the bottom of the pavement and around the well circle;

[0043] (2) Cutting and reverse excavation of the first well circle

[0044] When the water and water stability strength of the subbase reaches 50%, use the total station to stake out the center of the well circle, take the center of the well circle as the center, and draw a circle with the concrete pouring range of...

Abstract

The invention discloses an inspection well mounting construction technology. The inspection well mounting construction technology comprises the following steps: paving a subbase layer water stabilizer, cutting, backwards excavating a first well circle layer, paving the subbase layer water stabilizer, cutting, backwards excavating a second well circle layer, paving an asphalt bottom layer and an asphalt middle layer, cutting, backwards excavating a third well circle layer, mounting a well seat, and paving an asphalt top layer. The inspection well mounting construction technology disclosed by the invention has the advantages that reinforcing design is carried out from the subbase layer water stabilizer, a reinforced concrete structure fills outside a well wall, and a well wall structure of a roadbed layer is eliminated and is replaced by the reinforced concrete structure, so that a solid annular high-strength concrete holding power system ring is formed; and finally a direct stress layer, bonded with concrete, of the well seat is formed on a pavement layer, compaction is carried out with repeated load for three periods in the field by virtue of improvement of the scheme, and good reinforcement effect is obtained.

Description

technical field [0001] The invention relates to an inspection well installation and construction technology, which belongs to the field of building construction. Background technique [0002] At present, the urban entrance and exit roads are mainly heavy-duty traffic roads. Most of the drainage inspection wells in the roads are constructed according to the national building standard atlas "Municipal Drainage Pipeline Engineering and Auxiliary Facilities" (06MS201). After the roads are put into use, some inspection wells have subsided Cracks, uneven settlement and other diseases on the surrounding road surface have adverse effects on the appearance of the road and driving comfort, and even have a negative impact on the image of the city. Contents of the invention [0003] The object of the present invention is to provide an inspection well installation and construction process, which improves the existing construction method and reduces or avoids the defects of the inspecti...
