[0002] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous wall underground as a water interception, anti-seepage, load-bearing and water retaining structure.

[0003] During the construction of underground continuous walls, it is necessary to build guide walls first. Traditional guide wall formwork supports are supported by temporary wooden supports and cross supports. The wooden supports and cross supports need to be fixed in relative positions and then fixed with nails. This method has a slow construction speed and low efficiency, which results in a prolonged construction period. Utility Model Content

DETAILED DESCRIPTION

[0023] See also Figures 1 to 3As shown, the utility model provides a continuous combined support device for ground-connected wall pouring construction, which is used in a deep groove, and includes two support plates 1, at least one pair of screw rods 4, at least two support plates 6 and a hydraulic support structure 7. The two support plates 1 are arranged vertically and parallelly in the deep groove, and the two opposite sides of the two support plates 1 are each provided with at least one sliding groove 101 and fixed with at least one fixed seat 2, and the fixed seat 2 is fixed directly below the sliding groove 101, and the fixed seat 2 is provided with a horizontally extending sliding groove 21, and a horizontal slider 3 is slidably connected in the sliding groove 21; each of the screw rods 4 groups includes a screw rod 4 and a vertical slider 5, and the screw rod 4 is rotatably arranged in the sliding groove 101, and the vertical slider 5 is spirally connected to the outside of the screw rod 4; the support plate 6 corresponds to the screw rod 4 group one by one, and the two ends of the support plate 6 are respectively hinged to the horizontal slider 3 and the vertical slider 5.

[0024] The hydraulic support structure 7 includes a hydraulic box 71, a first piston rod 72, two second piston rods 73 and a hydraulic drive cylinder 74. The hydraulic box 71 is filled with hydraulic oil. The left and right ends and the lower end of the hydraulic box 71 are both connected with a fixed pipe 75. The first piston rod 72 is slidably arranged in the fixed pipe 75 at the lower end. One end of the two second piston rods 73 is slidably arranged in the fixed pipe 75 at the left and right ends respectively, and the other end is fixed to the two support plates 1 respectively and arranged beside the sliding groove 101. The lower end of the first piston rod 72 is fixed to the hydraulic drive cylinder 74. Specifically, the first piston rod 72 and the second piston rod 73 are both provided with a piston at one end in the fixed pipe 75, and are sealed and connected to the fixed pipe 75 through the piston.

[0025] The two support plates 1 are arranged at intervals in the vertical direction. By arranging a horizontal fixing seat 2 on the opposite sides of the two support plates 1 and arranging an inclined support plate 6 between the fixing seat 2 and the support plate 1, the support plates 1 can be supported. The two second piston rods 73 in the hydraulic support structure 7 further support the two support plates 1. The height of the first piston rod 72 is controlled by the hydraulic drive cylinder 74, so that the distance of the two second piston rods 73 extending can be controlled, thereby controlling the distance between the two support plates 1, which is convenient for pouring cement between the outer sides of the two support plates 1 and the side walls of the deep groove to form a guide wall. In this device, the support plates 1 are provided with a dual support effect by the support plate 6 and the hydraulic support structure 7, and are easy to disassemble and convenient for construction. The distance between the two support plates 1 can also be controlled, thereby ensuring that the distance between the two guide walls is accurate, thereby ensuring that the thickness of the underground continuous wall is accurate and uniform.

[0026] Preferably, each of the supporting plates 1 is provided with two sliding grooves 101 and two fixing seats 2 , the two sliding grooves 101 are arranged at intervals, and the second piston rod 73 is fixed between the two sliding grooves 101 .

[0027] By setting two sliding grooves 101 and two fixing seats 2, the support plate 6 can support and fix the two sides of the support plate 1, and the second piston rod 73 supports and fixes the middle position of the support plate 1, thereby ensuring that the supporting force of the support plate 1 is evenly distributed, thereby preventing the support plate 1 from tipping over when pouring cement between the outer side of the support plate 1 and the inner wall of the deep groove.

[0028] Furthermore, on the two opposite side walls of the support plate 1 , a splicing groove 102 is provided on one side wall, and a splicing block 103 is protruded on the other side wall, and the size of the splicing block 103 is adapted to the size of the splicing groove 102 .

[0029] Along the length direction of the deep groove, multiple support plates 1 can be spliced ​​together, and the splicing blocks 103 on two adjacent support plates 1 are inserted into the splicing grooves 102, so as to splice the multiple support plates 1 together, increase the length of the support plates 1, and thus improve the construction speed.

[0030] Furthermore, the splicing block 103 and the splicing slot 102 are both provided with a plurality of inserting holes 104 or threaded holes spaced apart from each other, and the inserting holes 104 or threaded holes on the splicing block 103 and the splicing slot 102 have the same spacing.

[0031] By simultaneously providing the same-spaced sockets 104 or threaded holes on the splicing block 103 and the splicing groove 102, after the support plates 1 are spliced, pins or bolts can be inserted into the sockets 104 to fix the two spliced ​​support plates 1, thereby preventing the splicing block 103 and the splicing groove 102 from separating due to excessive force. After the casting is completed, the pins and bolts are also easy to disassemble and convenient to use.

[0032] Specifically, in one embodiment, if Figure 1 As shown, the screw rod 4 is connected to the upper and lower side walls of the sliding groove 101 through bearings, and a telescopic driver 8 is provided in the sliding groove 21 , and the telescopic driver 8 is connected to the horizontal sliding block 3 .

[0033] When the telescopic driver 8 drives the horizontal slider 3 to move in the slide groove 21, it drives the support plate 6 to rotate, thereby driving the vertical slider 5 at the other end to move on the screw rod 4, thereby changing the inclination angle of the support plate 6. The screw rod 4 will only rotate when the vertical slider 5 moves, thereby ensuring the stability of the support plate 6. Specifically, the telescopic driver 8 can be an electric telescopic rod or a hydraulic telescopic cylinder.

[0034] In another embodiment, if Figure 2 As shown, a driving motor 11 is fixed to the upper end of the screw rod 4 , and a compression spring 9 is installed between the horizontal sliding block 3 and the sliding groove 21 .

[0035] The screw rod 4 is driven to rotate by the driving motor 11, thereby driving the vertical slider 5 to move on the screw rod 4, thereby changing the inclination angle of the support plate 6. At the other end of the support plate 6, the horizontal slider 3 applies a squeezing force to it through the compression spring 9, which also ensures the stability of the support plate 6.

[0036] In the above two embodiments, the position of the horizontal slider 3 or the vertical slider 5 is changed by the telescopic driver 8 or the driving motor 11, thereby changing the support angle of the support plate 6 to the support plate 1, which can be used to adapt to deep grooves of different depths. For example, when the height of the support plate 1 is higher than the height of the deep groove, the vertical slider 5 should move downward to reduce the support height of the support plate 6 to the support plate 1, and vice versa, the support height of the support plate 6 to the support plate 1 is increased. By adjusting the support angle of the support plate 6, the support plate 1 can be supported to make the support plate 1 more stable.

[0037] Furthermore, a pressure sensor is installed on the piston of the first piston rod 72, and the pressure sensor is electrically connected to an external terminal.

[0038] When the second piston rod 73 supports the support plate 1, the reaction force formed by the support plate 1 will be transmitted to the hydraulic oil through the first piston rod 72, and finally to the pressure sensor on the first piston rod 72. The cement pressure on the support plate 1 can be inferred from the reaction force received by the hydraulic oil.

[0039] Furthermore, a plurality of tapered rods 10 are fixedly connected to the lower side of the support plate 1 , and the tapered rods 10 can enable the support plate 1 to be inserted into the deep groove, thereby further fixing the position of the support plate 1 in the deep groove.

[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
