[0078] Further, the said side box culvert 300 includes: a first side edge 301 and a second side edge 302 connected end to end, and an arc-shaped edge 303;

[0079] The first side edge 301 is provided with a threaded hole matched with the first bolt through hole 207c, and the two are fastened by bolts;

[0080] The second side edge 302 is provided with a threaded hole matched with the second bolt through hole 203a, and the two are fastened by bolts;

[0082] It should be noted that the side box culvert 300 is divided into a left side box culvert and a right side box culvert and is symmetrically arranged along the tunneling direction of the shield tunneling machine, and is installed on both sides of the middle box culvert. Generally, the transport vehicle transporting the side box culvert is arranged in the position of the side box culvert along the tunneling direction of the shield tunneling machine in sequence according to the left side box culvert and the right side box culvert; and the left side box culvert is placed at a rotation angle of 180 degrees relative to the right side box culvert, so that after the lifting assembly 103 is lifted, the left and right side box culverts only need to be turned over by 90 degrees to make the first side edge 301 upward, and then the left side box culvert and the right side box culvert can be respectively installed in the position corresponding to the middle box culvert.

[0083] Further, in order to prevent the grabbing mechanism 200 from damaging the whole side box culvert 300 when the grabbing mechanism 200 is connected to the side box culvert 300, a nylon pad is arranged on the contact surface of the two, so as to further protect the integrity of the side box culvert 300.

[0085] Further, when pipe segment hoisting is required, the principle of the pipe segment hoisting and the middle box culvert hoisting can adopt the principle of the side box culvert hoist 100 in the application; the specific steps are as follows: when pipe segment hoisting is required, the side box culvert assembling device and the middle box culvert hoist are stopped at a specified position behind the hoisting track at this time;

[0086] The pipe segment transport vehicle transports the pipe segment to the specified area, and starts the pipe segment hoist to unload and hoist the pipe segment;

[0087] To avoid the interference between the grabbing mechanism and the pipe piece transport vehicle, after the middle box culvert crane runs backward to the set position and stops, the transverse frame together with the lifting assembly needs to be moved to the middle part of the walking frame first, and then the walking frame is started to move backward to the set position and stop.

[0088] Further, when the middle box culvert needs to be lifted and assembled, the side box culvert assembly and the pipe piece crane need to be stopped together at the set position in front of the lifting track;

[0089] The middle box culvert transport vehicle transports the middle box culvert to the set area, and the middle box culvert crane is started to unload and lift the middle box culvert to the assembly area for assembly;

[0090] To avoid the interference between the side box culvert assembly and the shield trailer when the side box culvert assembly walks forward and backward, before the side box culvert assembly leaves the side box culvert assembly area, the transverse frame together with the lifting assembly needs to be moved to the middle part of the walking frame first, and then the walking frame is started to move forward to the set position and stop.

[0091] Further, the construction method of the side box culvert assembly in the above-mentioned case specifically includes the following steps:

[0092] Step one, when the side box culvert is lifted and assembled according to the lifting track of the shield machine along the tunneling direction, the pipe piece crane needs to be stopped at the set position in front of the lifting track, and the middle box culvert crane needs to be stopped at the set position behind the lifting track, and then the side box culvert assembly is started to run to the side box culvert assembly area;

[0093] Step two, the side box culvert transport vehicle transports several side box culverts to the set position and stops;

[0094] Step three, the side box culvert crane 100 is started in reverse, the lifting assembly 103 is controlled to slowly lower the grabbing mechanism 200 to the set position, and the lifting assembly 103 is fine-tuned to align the grabbing mechanism 200 with the side box culvert 300 that needs to be lifted;

[0095] Step four, after the grabbing mechanism 200 is aligned with the side box culvert 100, bolt connection is performed to ensure that the grabbing mechanism 200 is tightly connected with the side box culvert 300;

[0096] Step five, then the side box culvert crane is started to work in forward direction, and the lifting assembly 13 is controlled to slowly lift the grabbing mechanism to the set position (higher than the position of the side box culvert transport vehicle support plate) and stop;

[0097] Step six, according to the grabbed side box culvert 300 (if it is a right side box culvert, the moving frame moves to the right; if it is a left side box culvert, the moving frame moves to the left), the transverse frame 102 drives the lifting assembly 203 and the side box culvert 300 to move horizontally to the set position and stop;

[0098] Step seven, after the side box culvert 300 is transversely moved to the set position, the lifting assembly 103 (specifically, the middle lifting device 103c slowly descends, and the left and right lifting devices ascend or stop) is controlled to overturn the side box culvert 300 by 90°, the middle lifting device 103c moves on the moving frame to approach the left and right lifting devices until the upper end surface of the side box culvert is in a horizontal state, and then the overturning is stopped;

[0099] Step eight, the lifting assembly 103 is controlled to slowly descend, the side box culvert 300 is lowered to the set position, the walking frame 101 is started to be slightly adjusted backward, and it is ensured that the side box culvert 300 is assembled in place;

[0100] Step nine, after the side box culvert 300 is fixedly connected with the middle box culvert, the bolt assembly is sequentially removed, the walking frame 101 is started to move forward by a set distance, after the grabbing mechanism is completely separated from the side box culvert 300, the lifting assembly 103 is started to lift the grabbing mechanism to a horizontal state, and then the walking frame is started to drive the grabbing mechanism 200 to move to the initial position and stop;

[0101] Step ten, the steps one to nine are repeated until the side box culvert is transported, lifted and assembled.

[0102] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.

the set position is higher than the position of the side box culvert transport vehicle support plate; Step six, according to the grabbed side box culvert, the moving direction of the moving frame is consistent with the direction of the corresponding side box culvert, the horizontal moving frame drives the lifting assembly and the side box culvert to move horizontally to the set position and stop; Step seven, after the side box culvert is horizontally moved to the set position, the lifting assembly is controlled to flip it by 90° until the upper end surface of the side box culvert is in a horizontal state and the flipping stops; Step eight, the lifting assembly is controlled to slowly descend, the side box culvert falls to the set position, the walking frame is started to fine-tune backward, and the hoisted side box culvert is ensured to be assembled in place; Step nine, after the side box culvert hoisted this time is fixed with the assembled middle box culvert, the bolt assembly is removed in turn, the walking frame is started to move forward by a set distance, after the grabbing mechanism completely separates from the side box culvert, the lifting assembly is started to lift the grabbing mechanism to a horizontal state, then the horizontal moving frame drives the grabbing mechanism to run to the initial position and stop; Step ten, repeat steps one to nine until the hoisting and assembly of the transported side box culvert are completed.
