[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 4 As shown, the present invention provides a joint box for an underground continuous wall socket joint, comprising: a box pipe 1, a side plate 2 and a back plate 3, wherein the box pipe 1 is in a square tube structure as a whole, and two box pipes 1 are arranged side by side; the back plate 3 is a square plate, and the side plates 2 are provided with two pieces, and the two side plates 2 are respectively vertically fixedly connected to the two side edges of the back plate 3; the side plates 2 and the back plate 3 form a C-shaped structure, the box pipe 1 is arranged between the two side plates 2, and the box pipe 1 is fixedly connected to the back plate 3; the top end of the box pipe 1 is provided with a connecting male head 4, and the bottom end of the box pipe 1 is provided with a connecting female head 10, and adjacent joint boxes are connected by plugging the connecting male heads 4 and the connecting female heads 10 of the box pipes 1 into each other.

[0018] Among them, a reinforcing plate 7 is arranged between the box tubes 1, and the reinforcing plate 7 is arranged as a strip plate, and the reinforcing plate 7 is arranged on the side of the box tube 1 away from the back plate 3, and the reinforcing plate 7 and the back plate 3 are parallel to each other; the reinforcing plate 7 is located at the protruding position of the water-stopping steel plate.

[0019] The arrangement of the reinforcing plate 7 can increase the structural strength of the two box pipes 1 when they are arranged, and maintain their own structural strength. When in use, the reinforcing plate 7 abuts against the protruding water-stopping steel plate, thereby preventing the water-stopping steel plate from being sandwiched by mud or concrete blocks.

[0020] Among them, the connecting male head 4 is a raised square tube, and a fixing hole 1 5 is arranged on the connecting male head 4, and a groove matching the connecting male head 4 is arranged in the connecting female head 10; and mutually aligned fixing holes 2 8 are arranged on the connecting female head 10 and the side plate 2, and the fixing holes 1 5 and the fixing holes 2 8 are aligned with each other and plugged into each other through steel pins.

[0021] The connecting male connector 4 and the connecting female connector 10 can be plugged into each other, and after the plugging, the fixing hole 1 5 and the fixing hole 2 8 can be aligned with each other, so that it is convenient to use a steel pin to clamp the fixing holes, thereby realizing the connection between the connecting male connector 4 and the connecting female connector 10, and ensuring the stability of the two sets of box pipes 1 after connection.

[0022] Partition plates 11 are arranged inside the box tube 1 , and a plurality of partition plates 11 are evenly arranged. The partition plates 11 are perpendicular to the side plates 2 and the back plate 3 . A connecting plate 9 aligned with the partition plates 11 is arranged between two box tubes 1 .

[0023] The provision of the partition plate 11 and the connecting plate 9 can increase the structural strength of the box tube 1 itself and the structural strength between each other, thereby extending the overall service life.

[0024] A square tube is arranged between the side plates 2 , and the square tube passes through the box tube 1 between the two side plates 2 . A jacking hole 6 is arranged in the square tube.

[0025] The top-pull hole 6 formed by the square tube can be connected to the steel bar of the plug when in use to achieve overall installation.
