Embodiment 1

[0021] A prefabricated pipe gallery structure, such as figure 1 As shown, including the main body of the pipe gallery, one end of the main body of the pipe gallery is a double-step rebate 1, and the other end is a three-step rebate 8. Such as figure 2 and Figure 4 As shown, the bottom of the pipe gallery body is provided with a first step 2, the top of the pipe gallery body is provided with a second step 3, a groove 4 is provided between the two steps, and a rubber strip 5 with double airbags is provided in the groove 4. The rubber strip 5 is ring-shaped, two airbags are arranged in parallel in the middle of the rubber strip 5, and extend along the circumferential direction of the rubber strip 5, and one side of the rubber strip 5 is fixedly arranged in the groove 4 of the pipe gallery body, that is, in the prefabricated pipe gallery body During the process, it is embedded in the pipe gallery body, the first airbag 6 is filled in the groove 4, and the second airbag 7 facin...

Embodiment 2

[0024] On the basis of Example 1, in order to further enhance the joint sealing of the prefabricated pipe gallery, the inner walls of the double-step rebate 1 and the three-step rebate 8 are provided with grouting grooves 10 for pouring waterproof grout. The grouting tank 10 is arranged inside the main body of the pipe gallery, which is convenient for maintenance. A grouting groove with a funnel-shaped opening is preferred, so that the slurry can fully flow into the joint gap. The grouting tank preferably has a symmetrical structure, such as Figure 6 As shown, the edge chamfer of the second step 3 of the double-step rebate is inclined, and the edge chamfer of the corresponding step of the three-step rebate is inclined, which is prefabricated with the main body of the pipe gallery.

Abstract

The invention belongs to the technical field of construction engineering. In order to overcome the problem that the water stop bar of the pipe gallery expands when it encounters water and the construction is limited in rainy days, a prefabricated pipe gallery structure is provided, including the pipe gallery body. One end of the pipe gallery body is a double-step groove. A first step is set at the bottom, a second step is set at the top of the pipe gallery body, a groove is set between the two steps, and an annular rubber strip with double airbags is set in the groove, and the two airbags are arranged in parallel in the middle of the rubber strip, and Extending along the circumference of the rubber strip, one side of the rubber strip is preset in the groove of the pipe gallery body, the airbag is filled in the groove, and the outward airbag is placed outside the groove; the other side of the rubber strip is L The end of the L-shaped side rests on the first step; the other end of the pipe gallery body is a three-step groove, and the middle step corresponds to the groove. The invention adopts the built-in double-airbag rubber strip, which has good sealing performance and unlimited construction environment.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prefabricated pipe gallery structure. Background technique [0002] In the existing technology, the concrete prefabricated pipe gallery is referred to as "prefabricated pipe gallery" for short, and is mainly used for the centralized arrangement of various underground pipelines. The working environment is underground, and anti-leakage is an important measure for the safe operation of the pipe gallery. The current prefabricated pipe gallery is mainly divided into integral prefabricated pipe gallery and block prefabricated pipe gallery. The overall prefabricated pipe gallery is divided into short sections on the longitudinal axis for prefabrication, and then assembled at the construction site. The pipe gallery is perpendicular to the longitudinal axis. The horizontal stitching seams need to be treated with anti-leakage. At present, the anti-leakage of...
