[0003] Regarding the above-mentioned related technologies, the more common method at present is to install a jacking pipe outside the tunnel, that is, to open an opening at the top of the horizontal tunnel, install a corresponding structure at the opening, and then reinforce the surrounding area, and finally, open the vertical tunnel, so as to achieve rapid docking of the two tunnels and avoid the occurrence of messy docking problems of multiple tunnels.

[0041] A construction method of a cross-tube structure, referring to Figure 1 and Fig.10 , including the following steps: S1: confirming the installation position of the jacking pipe, that is, determining the installation position of the jacking pipe body 3 between the first tunnel 1 and the second tunnel 2 through measurement technology; S2: After the pipe jacking machine drills the hole and determines the installation position of the pipe jacking body 3, the pipe jacking machine is used to open the hole body accommodated by the pipe jacking body 3 in the first tunnel 1 and the second tunnel 2; S3: Pipe jacking and pipe forming. During the process of the pipe jacking machine rotating and opening a hole, the materials formed by the pipe jacking body 3 are pushed in sequence to form the pipe jacking body 3; S4: The interface end between the tunnel and the top pipe is reinforced. Before drilling, a steel connecting piece 6 is installed on the outside of the first tunnel 1 and the second tunnel 2, so that the steel connecting piece 6 and the top pipe body 3 are reinforced and connected through the first steel-mixed pipe 4 and the second steel-mixed pipe 5 installed on both sides, and an anti-leakage structure 7 is installed inside the top pipe body 3 to prevent leakage.

[0042] By adopting the above construction method, the installation of the jacking pipe body 3 can be quickly realized, and the tunnel connection efficiency can be accelerated without occupying too much land resources.

[0043] The implementation principle of the embodiment of the present application is: First, after the first tunnel 1 is connected with the second tunnel 2 and the top pipe body 3, and the first steel-mixed pipe 4, the second steel-mixed pipe 5 and the steel connecting piece 6 are connected to complete the installation and stabilization of the overall structure, the anti-leakage structure 7 can be installed in sequence at the lower end of the top pipe body 3, that is, when external sewage invades the top pipe body 3, it can flow along the curvature of the inner wall of the top pipe body 3 to the drainage port 73 opened on both sides of the upper end of the aisle plate 71, so that the sewage is collected into the water collection box 74 along the drainage ports 73 on both sides, so as to avoid the sewage from affecting the electronic components installed inside the top pipe body 3 and avoid the occurrence of the problem of flooding of the top pipe body 3; Second, when the liquid level sensors 75 provided on both sides of the lower end of the aisle plate 71 detect that the collected sewage exceeds the set water level, the pump body connected to the outside of the drainage pipe 772 can be driven, so that the sewage collected in the water collecting tank 74 will be filtered by the filter cartridge 776 and sucked into the suction pipe 775. The suction pipe 775, the water guide joint 774, the bellows 773 and the drainage pipe 772 are connected to each other, so that the sewage can be quickly discharged. In order to ensure that the filter cartridge 776 is not easily blocked during the drainage process, the cylinder 7716 can be driven to move the connecting plate 7715 connected to the upper end up and down. As the connecting plate 7715 moves up and down, the suction pipe 775 will push the filter cartridge 776 up and down to change the water absorption position and speed up the water absorption and discharge efficiency. At the same time, when the connecting plate 7715 moves up and down, the rack 7714 connected to the other side of the connecting plate 7715 will move up and down synchronously, and realize the positive and negative rotation of the gear 7713 accordingly, so that the second bevel gear 7712 arranged on one side of the gear 7713 will rotate synchronously to mesh with the first bevel gear 7711. In this way, the first bevel gear 7711 will realize the synchronous rotation of the sleeve 777, and cooperate with the limiting rings 778 on both sides of the outer end to realize the positive and negative rotation of the connecting cylinder 779 connected at the bottom. In this way, when the filter cartridge 776 is moved back into the connecting cylinder 779, it will be reciprocated by the brush strip 7710 installed inside the connecting cylinder 779 to realize the brushing and cleaning of the sludge attached to the outside of the filter cartridge 776, reduce the sludge adhesion, and speed up the water absorption and discharge efficiency. Third, when it is necessary to clean the sludge inside the water collecting tank 74, the servo motor 761 can be operated to realize the simultaneous rotation of the multi-segment screw 762. As the multi-segment screw 762 rotates, the first connecting block 763 connected to the outer end of the transmission is driven to enable the first connecting block 763 to realize the backward movement of the horizontal bar 764 connected to the bottom. In this way, the scraper bar 766 set at the lower end of the vertical bar 765 will be synchronously moved backward, so that the scraper bar 766 can push back the sludge attached to the lower end of the water collecting tank 74, and push the sludge to the position of the opening and closing door 72. In this way, the sludge can be manually cleaned by opening the opening and closing door 72. At the same time, the cooperation of the second connecting blocks 767 and the guide rods 768 at multiple locations can ensure the stability of the forward and backward movement of the scraper bar 766 and the efficiency of the sludge scraping and cleaning.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
