Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to a joint box for a socket joint of underground continuous wall. Background Technology

[0002] With the rapid development of underground engineering construction in my country, shallow urban spaces are gradually becoming saturated, while deep space development is increasing, leading to deeper excavations and higher requirements for environmental protection. Diaphragm walls, as retaining structures, have minimal impact on surrounding buildings, exhibit low construction vibration and noise, and are increasingly being used in large-scale deep foundation pit projects such as subways, real estate developments, and bridge piers.

[0003] As a weak link in the diaphragm wall, the joint of the diaphragm wall directly affects the deformation and seepage prevention effect of the entire diaphragm wall, and thus affects the safety of the entire foundation pit and the surrounding environment. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a joint box for a socket joint of underground continuous wall, which has the advantage of more precise operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a joint box for a socket-type joint in a diaphragm wall, comprising: a box tube, side plates, and a back plate. The box tube is generally square-tube shaped, and two box tubes are arranged side by side. The back plate is a square plate, and two side plates are provided, which are respectively fixedly connected to the two sides of the back plate perpendicularly. The side plates and the back plate form a C-shaped structure. The box tube is arranged between the two side plates and is fixedly connected to the back plate. A male connector is provided at the top of the box tube, and a female connector is provided at the bottom of the box tube. Adjacent joint boxes are connected by interlocking the male and female connectors of the box tubes.

[0006] As a preferred embodiment of this utility model, a reinforcing plate is provided between the box tubes. The reinforcing plate is a strip plate and is located on the side of the box tube away from the back plate. The reinforcing plate and the back plate are parallel to each other.

[0007] As a preferred embodiment of this utility model, the male connector is a raised square tube with a fixing hole 1 provided on it, and the female connector has a groove that matches the male connector. The female connector and the side plate are provided with two fixing holes that are aligned with each other. After the fixing holes 1 and 2 are aligned with each other, they are connected to each other by steel pins.

[0008] As a preferred embodiment of this utility model, a partition is provided inside the box tube, and multiple partitions are evenly arranged. The partitions are perpendicular to the side plates and the back plate. A connecting plate aligned with the partitions is provided between two box tubes.

[0009] As a preferred embodiment of this utility model, a square tube is provided between the side plates, the square tube passes through the box tube between the two side plates, and a pull-out hole is provided in the square tube.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The joint box provided by this utility model realizes the mutual connection of different joint boxes by setting matching structures at both ends of the box tube, and increases the overall structural strength by adding a plate to the outside of the box tube; it has the advantages of good overall stress performance, high structural strength and rigidity, and prevention of pressurized water leakage, and has broad market application prospects.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4As shown, this utility model provides a connector box for a socket-type joint of a diaphragm wall, comprising: a box tube 1, side plates 2, and a back plate 3. The box tube 1 is generally square tube in shape, and two box tubes 1 are arranged side by side. The back plate 3 is a square plate. Two side plates 2 are provided, and the two side plates 2 are respectively fixedly connected to the two sides of the back plate 3 perpendicularly. The side plates 2 and the back plate 3 form a C-shaped structure. The box tube 1 is arranged between the two side plates 2 and is fixedly connected to the back plate 3. The top end of the box tube 1 is provided with a male connector 4, and the bottom end of the box tube 1 is provided with a female connector 10. Adjacent connector boxes are connected by interlocking the male connector 4 and the female connector 10 of the box tube 1.

[0018] Among them, a reinforcing plate 7 is provided between the tubes 1. The reinforcing plate 7 is a strip plate and is located on the side of the tube 1 away from the back plate 3. The reinforcing plate 7 is parallel to the back plate 3. The position of the reinforcing plate 7 is the protruding position of the water-stopping steel plate.

[0019] The reinforcing plate 7 increases the structural strength of the two casing pipes 1 during installation, maintaining their structural strength. During use, the reinforcing plate 7 abuts against the protruding waterstop steel plate, preventing mud or concrete blocks from getting trapped inside.

[0020] The male connector 4 is a raised square tube with a fixing hole 5. The female connector 10 has a groove that matches the male connector 4. The female connector 10 and the side plate 2 have fixing holes 8 that are aligned with each other. The fixing holes 5 and 8 are aligned with each other and then connected by steel pins.

[0021] The male connector 4 and the female connector 10 can be plugged into each other, and after plugging, the fixing holes 1 5 and 2 8 can be aligned with each other, which makes it easy to use steel pins to snap the fixing holes together, thereby realizing the connection of the male connector 4 and the female connector 10 and ensuring the stability of the two sets of box tubes 1 after connection.

[0022] The box tube 1 is provided with a partition 11, and multiple partitions 11 are evenly arranged. The partitions 11 are perpendicular to the side plate 2 and the back plate 3. A connecting plate 9 is provided between two box tubes 1, which is aligned with the partitions 11.

[0023] The installation of partition 11 and connecting plate 9 can increase the structural strength of the box tube 1 itself and the structural strength between them, thus extending the overall service life.

[0024] A square tube is provided between the side plates 2, and the square tube passes through the box tube 1 between the two side plates 2. A top-pull hole 6 is provided in the square tube.

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