Problems solved by technology

Among them, masonry wells have high technical requirements for labor and short service life; the construction process of cast-in-place reinforced concrete wells is cumbersome, requiring multiple processes such as erecting formwork and binding steel bars; prefabricated reinforced concrete wells are large in volume and quality, which is inconvenient transport and installation
The construction time of traditional wells is long, the labor demand is large, the construction is greatly affected by the environment, and the construction quality is difficult to guarantee, the maintenance cost is high, and the transportation is inconvenient
Due to the fixed size of the standard section of the prefabricated well, for projects that require multiple sizes, it is necessary to customize standard sections of different sizes, the cost is very high, and the transportation cost of the standard section is high

Embodiment 1

[0052] Such as figure 1 , 2 , 3, 4, 5 and 6, the assembled work well standard section includes an assembly and a connector 3, the assembly includes an inner plate 4 and an outer plate 5, and several The longitudinal rib 7 is provided with a transverse rib 6 on the top, and the inner and outer plates 4 and 5 are connected to the transverse rib 6 through the longitudinal rib 7. The protrusion forms a bump 61, and its bottom is provided with a groove 8 matching the bump 61. During assembly, the bump 61 is inserted into the groove 8 of the assembly of the adjacent well standard section 10 to realize connection. The bottom surface of the longitudinal rib 7 is slightly higher than the bottom surface of the inner plate 4 and the outer plate 5 and forms a groove 8 with the bottom surface of the inner plate 4 and the outer plate 5. The bottom surfaces of the plate 4 and the outer plate 5 are flush, and the above-mentioned groove 8 is opened on the bottom surface of the longitudinal r...

Embodiment 2

[0073] The difference between this embodiment and Embodiment 1 is that: Figure 17 with 18As shown, the cable pipe port 13 is located between the two working well standard joints, so the two working well standard joints are the opening standard joints, and the lower hole 101a mark is made on the two working well standard joints, and then the on-site opening The holes are either not removed and directly drilled on the hole standard joint, or the two standard joints of the well have been prefabricated in the factory in advance. All the connectors 3 on the standard section of the labor well are not located on the orifice 101a. Other structures, principles and installation methods are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides an assembled type working wheel standard joint and an installation method of the assembled type working well standard joint in a new project, belongs to the technical field of pipeline working wells, and solves the problems in the existing new project, the size of a working well is difficult to adjust, the construction efficiency is low, and the construction quality is poor. The installation method of the assembled type working well standard joint comprises the following steps: S1, digging a foundation pit; S2, installing a first working well standard joint; S3, installing a second working well standard joint; S4, continuing installing the working well standard joint to a cable pipe orifice; S5, trepanning the standard joints; S6, continuing installing the working well standard joint to the calculated elevation, and installing a temporary cover plate; and S7, backfilling a gap between the working well and the foundation pit, removing the temporary cover plate, and installing a well cover. The installation method of the assembled type working well standard joint has the advantages of high construction efficiency and quality and small labor force of the construction.

Description

technical field [0001] The invention belongs to the technical field of pipeline wells, and relates to an assembled standard well joint and its installation method in new construction. Background technique [0002] The wells are mainly for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, communication, cable TV, gas pipes, street lamp lines, etc., and are conveniently installed. It is generally located at pipeline intersections, turnings, pipe diameter or slope changes, and at certain distances on straight pipe sections. It is an auxiliary structure that is convenient for regular inspection. [0003] Traditional wells generally adopt reinforced concrete structure or masonry structure. Among them, masonry wells have high technical requirements for labor and short service life; the construction process of cast-in-place reinforced concrete wells is cumbersome, requiring multiple processes such as erecting formwork and binding ste...
