[0008] As a further embodiment of the present invention, the fixing base includes: a connecting slot A, which is T-shaped and located at the rear end of the fixing base; the connecting slot A matches the connecting block A; three connecting side frames are fixedly installed on one side of the fixing base; a drive shaft, which is circular and rotates at one end of the connecting side frame; an adjusting screw, which rotates in the middle of the connecting side frame; one end of the adjusting screw is connected to the drive shaft via a bevel gear; and an adjusting slide, which is rectangular and slides on one side of the fixing base.
[0009] As a further embodiment of the present invention, the fixing base further includes: an adjusting cylinder, wherein the number of adjusting cylinders is set to three, and the adjusting cylinders are fixedly installed on one side of the adjusting slide; the adjusting cylinders are threadedly connected to the adjusting screw; a connecting groove B, the connecting groove B is T-shaped and is located at the rear end of the adjusting slide; a fixing side block, the fixing side block is rectangular and is set to two sets, the fixing side blocks are symmetrically fixedly installed at the front end of the top of the fixing base; and a fixing groove, the fixing groove is T-shaped and is located at the bottom of the fixing side block.
[0010] As a further embodiment of the present invention, the fixing base further includes: a mounting bracket, the mounting bracket being L-shaped and engaging with the top of the fixing base and the top of the adjusting slide; a fixing block, the fixing block being T-shaped and having two fixing blocks, which are symmetrically and integrally disposed on both sides of the bottom of the mounting bracket; the fixing blocks engaging with fixing slots; and two limiting joints, which are symmetrically and integrally disposed on both sides of the other end of the mounting bracket.
[0011] As a further embodiment of the present invention, the fixing base further includes: a limiting slider, the limiting slider being rectangular in shape and sliding on one side of the mounting bracket; a contact block, the contact block being rectangular in shape and integrally disposed at the bottom of the limiting slider; and two connecting heads, the connecting heads being symmetrically and integrally disposed on both sides of the limiting slider.

[0013] The prefabricated mud box for slurry balance pipe jacking provided by the present invention has the following beneficial effects:
[0014] After the main structure of the mud tank is assembled, to further improve its sealing performance, the construction personnel will initiate a sealing enhancement operation. By rotating the drive shaft, the drive shaft uses the transmission action of bevel gears to drive the adjusting screw to rotate synchronously. Since the adjusting screw and the adjusting cylinder are connected by a thread, when the adjusting screw rotates, the adjusting cylinder will move along the axial direction of the adjusting screw, which in turn drives the adjusting slide to move. As the adjusting slide moves, the sealing strip originally installed between mud tank side plate A and mud tank side plate B will be compressed to a certain extent. This compression action can make the sealing strip fit more tightly between the components, thereby effectively improving the sealing performance between mud tank side plate A and mud tank side plate B, ensuring that the mud tank will not leak during use.
[0015] In addition, to further enhance the overall stability and sealing of the mud tank, the construction workers will perform additional reinforcement operations. They will insert multiple sets of mounting brackets between the fixed side blocks at different positions, and then push the mounting brackets upward. During the pushing process, the fixing blocks on both sides of the mounting bracket will smoothly insert into the fixing slots, achieving the initial positioning of the mounting bracket. Next, the construction workers will rotate the connecting screw. Since the connecting screw and the mounting bracket are threaded, the rotation of the connecting screw will drive the limiting slider to move downward. As the limiting slider moves downward, the contact block at its bottom will gradually contact the top of the connecting block A and the connecting block B of mud tank side plate A and side plate B. During the continuous downward movement, the contact block will apply downward pressure to mud tank side plate A and side plate B. This downward pressure can make the mud tank side plate fit more tightly with the assembly box base, further strengthening the sealing of mud tank side plate A and side plate B with the assembly box base, providing a reliable mud storage and treatment facility for mud-water balance pipe jacking construction.

Sealing strips 107 are installed between the sealing grooves A103 and B106 of mud box side plates A101 and B104 and the assembly box base 1. During the placement of mud box side plates A101 and B104, the connecting clip A102 of mud box side plate A101 is inserted into the connecting clip slot A201 and the connecting clip B105 of mud box side plate B104 is inserted into the connecting clip slot B207, so that mud box side plates A101 and B104 can be stably placed on the assembly box base 1, thereby completing the mud box assembly operation.
