Problems solved by technology

Although the working joint can expand the cross-sectional size of the working pipe joint, it is convenient for construction personnel and construction equipment to perform tensioning operations inside the working pipe joint; however, the pipe joint has the following deficiencies: 1. The pipe joint connection in the transverse bearing pipe curtain structure The connection between the mother and child buckles makes the installation of the pipe joints inconvenient, and the gap between the mother and child buckles is inconvenient and full, resulting in poor installation firmness; 2. The support between the upper pipe joint and the pipe joint in the horizontal bearing pipe curtain structure Insufficient force leads to the subsidence of the upper pipe curtain under the gravity of the soil after the excavation of the soil, which affects the support effect of the horizontal bearing pipe curtain structure and also affects the later structural construction

Embodiment 1

[0053] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 and Figure 8 , a pipe section member suitable for lateral bearing tube curtain structure, including four working tube sections 1 and several pipe jacking tube sections 2; the four working tube sections 1 are located at the four corners of the lateral bearing tube curtain structure; The two adjacent working joints are connected by a plurality of pipe jacking joints;

[0054] Two mutually perpendicular socket members 4 and tenon members 6 are fixedly provided on the outer side of the working joint, and socket members 4 and tenon members 6 are also fixedly provided on both sides of the outer side of the jacking pipe section 2; There are at least two mortise grooves 41 with an isosceles trapezoid cross-section, and at least two frame-shaped tenons 61 with a rectangular cross-section are provided on the tenon member 6; the frame-shaped tenons 61 are formed of deformed metal plates, and...

Embodiment 2

[0061] see figure 1 , figure 2 , image 3 , Figure 9 , this embodiment adds the following scheme on the basis of Embodiment 1: between the working pipe section 1 and the pipe jacking pipe section 2 on the top layer of the lateral bearing pipe curtain structure, and between the pipe jacking pipe section 2 and the pipe jacking pipe section 2 There are pipe section gaskets 3 between them.

[0062] The pipe section gasket 3 includes side wings 31 symmetrically arranged on both sides, and the upper ends of the two side wings 31 are fixedly connected; There is a reserved bolt hole 8 at the bottom left or below, and the working pipe section 1 and the jacking pipe section 2 are located inside the bolt reserved hole 8 with a pre-embedded threaded steel sleeve 5; 7 Connect to the pre-embedded threaded steel sleeve 5 through the reserved installation holes 32 and the reserved bolt holes 8, so that the pipe section gasket 3 is fixed between the working pipe section 1 and the pipe ja...

Abstract

The invention relates to the technical field of engineering construction, and provides a pipe joint component suitable for a transverse bearing pipe roofing structure, which is characterized in that a working pipe joint and a jacking pipe joint of an upper layer in the transverse bearing pipe roofing structure are connected through a mortise component and a tenon component, and the jacking pipe joints are connected through the mortise component and the tenon component; expansion concrete is poured into the expansion concrete pouring holes of the frame-shaped tenons, the frame-shaped tenons are driven by expansion of the expansion concrete to deform, the frame-shaped tenons are matched with the inner walls of the mortises in shape, a firm mortise and tenon structure is formed, and therefore the working pipe joint and the jacking pipe joint are connected to form a transverse bearing pipe curtain, and a firm supporting structure is achieved; and a good waterproof function is achieved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a pipe section member suitable for a transverse bearing pipe curtain structure. Background technique [0002] As a new type of underground excavation construction method, the pipe curtain method has been widely used in the development of underground space due to its unique technical advantages. The method is to use a small pipe jacking machine to push the steel pipe into the soil between the originating well and the receiving well, and each single pipe is connected to the side of the steel pipe by means of a lock to form a pipe row, and injected into the gap of the lock. The water-stop material cuts off the surrounding water and soil to form an advanced support system; then the soil excavation and structural construction are carried out under the support of the pipe curtain. [0003] According to Chinese Patent Application No. 202010557882.7, a working tube sect...
