[0025] The invention discloses a synchronous pouring device for underground continuous wall, comprising a first pouring pipe 1, a second pouring pipe 2, a connecting frame 3 and two measuring structures 4. The first pouring pipe 1 and the second pouring pipe 2 are arranged in a corresponding manner along a straight line at intervals. The two ends of the connecting frame 3 are respectively connected to the first pouring pipe 1 and the second pouring pipe 2. The connecting frame 3 is provided with a lifting ring 6 for lifting. The two measuring structures 4 are respectively installed on the connecting frame 3, and the two measuring structures 4 are respectively used to detect the pouring depths of the first pouring pipe 1 and the second pouring pipe 2. The measuring structure 4 comprises a measuring rope 41 and a floating plate 42. The lower part of the measuring rope 41 is connected to the floating plate 42. The floating plate 42 is placed in a continuous groove and is arranged corresponding to the first pouring pipe 1 or the second pouring pipe 2. The floating plate 42 is arranged to float upward due to the poured concrete.

[0026] When the underground continuous wall synchronous pouring device mentioned above is performing underground continuous wall pouring operations, under the action of the connecting frame 3, a single lifting device can realize the synchronous lifting and lowering of the first pouring pipe 1 and the second pouring pipe 2, which is convenient for construction operations and realizes the synchronous pouring of concrete by two pipes, thereby improving the pouring effect and the pouring quality. During the specific pouring process, the pouring depth of the concrete is monitored through the cooperation of the measuring rope 41 and the floating plate 42 to ensure that sufficient concrete is poured before lifting the first pouring pipe 1 and the second pouring pipe 2, thereby ensuring the pile quality and support strength.

[0027] The measuring structure 4 comprises a measuring sleeve 43 , the measuring sleeve 43 is sleeved with the connecting frame 3 , and the upper part of the measuring rope 41 is connected to the measuring sleeve 43 ; under the action of the measuring sleeve 43 , the setting of the measuring rope 41 is facilitated.

[0028] The connecting frame 3 has a plurality of pop-up frame columns, the measuring sleeve 43 has a pipe opening, the frame columns are embedded in the pipe opening, the frame columns are used to position the measuring sleeve 43, and the frame columns are pressed to separate from the pipe opening; in this way, through the cooperation between the frame columns and the pipe opening, the lateral position of the measuring sleeve 43 can be adjusted, and the position of the measuring rope 41 can be adjusted.

[0029] The measuring structure 4 includes an adjusting platform 44, which is arranged to be connected with the floating plate 42 in an upper and lower manner. The adjusting platform 44 is arranged in the middle of the floating plate 42, and the adjusting platform 44 is used to level the floating plate 42. Under the action of the adjusting platform 44, the overall center of gravity of the measuring structure 4 tends to the middle, avoiding horizontal deviation of the measuring structure 4, facilitating the horizontal arrangement of the floating plate 42, thereby facilitating the monitoring of the pouring depth of concrete.

[0030] The measuring structure 4 includes a plurality of adjusting columns 45 , which are arranged longitudinally, with the upper portion of the adjusting columns 45 butted against the floating plate 42 , and the lower portion of the adjusting columns 45 extending vertically away from the floating plate 42 ; when pouring concrete, the adjusting columns 45 are embedded in the concrete.

[0031] In this way, during the pouring process of concrete, the floating plate 42 is effectively kept level under the action of each adjusting column 45, so that the pouring depth of concrete can be monitored easily.

[0035] The measuring structure 4 includes a tension sensor 5, which is installed on the measuring rope 41 and is used to detect the tension data of the measuring rope 41. Under the action of the tension sensor 5, when the concrete pushes the floating plate 42 to float up, the tension of the measuring rope 41 will change. Once the tension change exceeds the preset value, it proves that the injection volume is sufficient, and the first injection pipe 1 and the second injection pipe 2 can be lifted.

The depth of the concrete surface can be accurately known through the measuring rope 41. The motor 47 is controlled by the control panel, which saves manpower and facilitates the measurement of the concrete surface, effectively guarantees the pouring quality of the pile, and can also effectively control material waste, and the measurement effect is good.

[0037] The first pouring pipe 1 includes a first tube body 11 and a first funnel 12. The first funnel 12 and the first tube body 11 are arranged correspondingly up and down. The first funnel 12 is arranged in a cone shape with a large top and a small bottom. The first tube body 11 and the first funnel 12 are respectively used for pouring concrete. Under the action of the first funnel 12, the pouring of concrete is guided, which facilitates the transportation of concrete to the first tube body 11, thereby facilitating the pouring of concrete into the underground continuous tank.

[0038] The underground continuous wall synchronous pouring device includes a first vibration plate 13, which is arranged in a flat and abutting relationship with the first funnel 12, and the first vibration plate 13 is arranged in a vibrating manner; under the action of the first vibration plate 13, vibration force is applied to facilitate the transfer of concrete to the first pipe body 11, thereby facilitating the pouring of concrete.

The second funnel is arranged in a cone shape with a larger top and a smaller bottom. The second tube body and the second funnel are used for pouring concrete respectively. Under the action of the second funnel, the pouring of concrete is guided, which facilitates the transportation of concrete to the second tube body, thereby facilitating the pouring of concrete into the underground continuous tank.

[0040] The underground continuous wall synchronous pouring device comprises a second vibration plate, which is arranged in a flat and abutting manner with the second funnel, and the second vibration plate is arranged in a vibrating manner.

[0041] Under the action of the second vibration plate, a vibration force is applied to facilitate the transfer of concrete to the second pipe body, thereby facilitating the pouring of concrete.

[0042] The first perfusion pipe 1 includes a first waterstop plate, which is used to block or conduct the first tube body 11 and the first funnel 12. The second perfusion pipe 2 includes a second waterstop plate, which is used to block or conduct the second tube body and the second funnel.

The two waterstop ropes converge to form a lifting part, and the lifting part and the lifting ring 6 are arranged in correspondence with each other up and down.

[0043] In this way, when concrete pouring is carried out, the first water stop plate and the second water stop plate respectively block the first tube body 11 and the second tube body. After the first funnel 12 and the second funnel are filled with a certain amount of concrete, the first water stop plate and the second water stop plate are lifted to make the first funnel 12 and the first tube body 11 conductive, and to make the second funnel and the second tube body conductive, thereby realizing the pouring of concrete.
