DETAILED DESCRIPTION

[0019] To make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application.

[0020] The embodiment includes several rectangular sliding frames 2, which are hollow inside. The support blocks 3 are arranged to slide in the rectangular sliding frames 2 and can slide forward and backward in the rectangular sliding frames 2. The width of the support blocks 3 is smaller than the distance between the adjacent vertical bars of the reinforcement cage 4 in the underground continuous wall slot, so the support blocks 3 can pass between the adjacent vertical bars of the reinforcement cage 4. The rear side of the support blocks 3 is uniformly provided with several adjusting holes 5, and the rear side of the rectangular sliding frames 2 is provided with through holes 7 corresponding to the adjusting holes 5. The horizontal pin column 8 can pass through the adjusting holes 5 and the through holes 7 to connect the support blocks 3 and the rectangular sliding frames 2 together. The two sides of the pin column 8 are both provided with vertical insertion holes 9, and the insertion pins 10 are inserted into the insertion holes 9. The insertion pins 10 are used to prevent the support blocks 3 from sliding forward and backward, and the U-shaped insertion pins are preferred in the embodiment. The front top surface of the support blocks 3 is provided with several threaded holes A6 on the left and right sides, which are used to fix the support plates 16.

[0021] The two sides of the rectangular sliding frames 2 are respectively provided with suction cups 11, which are used to be adsorbed on the top surface of the guide wall 1. Since the guide wall 1 is formed by pouring concrete, a special concrete suction cup can be selected, such as an electric suction cup, a pneumatic suction cup, a vacuum suction cup, etc. The specific selection can be made according to the needs, as long as the suction cup 11 can be tightly adsorbed on the top surface of the guide wall 1. The top surface of the suction cup 11 is fixed with a long screw rod 12 upward, and the upper side of the two suction cups 11 is provided with a pressing plate 13. The pressing plate 13 is provided with a strip-shaped hole 14, the long screw rod 12 passes through the strip-shaped hole 14 upward, and the long screw rod 12 is provided with a pressing nut 15. The pressing nut 15 fixes the long screw rod 12 and the pressing plate 13 together, and the downward tightening of the pressing nut 15 can make the pressing plate 13 tightly press the rectangular sliding frame 2 below.

[0022] The embodiment also includes a support plate 16, which is placed on two adjacent support blocks 3. The left and right sides of the support plate 16 are both provided with threaded holes B17 corresponding to the threaded holes A6, and the support plate 16 is fixed on the support blocks 3 through the fastening bolts 18 passing through the threaded holes A6 and the threaded holes B17. The support plate 16 is provided with a positioning hole 19 in the middle, which is used to pass through the guide pipe 25 for pouring concrete, so the diameter of the positioning hole 19 is equal to the outer diameter of the guide pipe 25. Two positioning blocks 20 are symmetrically fixed on both sides of the positioning hole 19. The positioning blocks 20 are provided with a circular hole, a horizontal moving screw rod 21 is arranged in the circular hole, the moving screw rod 21 is provided with a nut, the end of the moving screw rod 21 towards the positioning hole 19 is fixed with a half-circle clamp 22, and the two half-circle clamps 22 are fixed together through bolts. The two half-circle clamps 22 form a clamp for fixing the guide pipe 25.

[0023] As a further scheme, several inverted U-shaped rings 24 are welded on the top ends of the adjacent vertical bars of the reinforcement cage 4, and several notches 23 are provided on the left and right sides of the support plate 16. The inverted U-shaped rings 24 correspond to the notches 23 one by one, the notches 23 can make the inverted U-shaped rings 24 pass through, and the inverted U-shaped rings 24 are hung on the support blocks 3.

[0024] During construction, a plurality of inverted U-shaped rings 24 are welded to the top ends of the vertical reinforcement bars of the reinforcement cage 4 placed in the slot hole, and a rectangular sliding frame 2 is placed on the top surface of the guide wall 1 at every interval, and the position of the rectangular sliding frame 2 corresponds to the position of the inverted U-shaped ring 24, so that the inverted U-shaped ring 24 can be hung on the support block 3 in the rectangular sliding frame 2. The support block 3 is inserted into the rectangular sliding frame 2, and then the suction cup 11 is fixed on both sides of the rectangular sliding frame 2, so that the suction cup 11 is tightly attached to the top surface of the guide wall 1. The pressing plate 13 is sleeved on the long screw rod 12 of the suction cup 11, and the pressing plate 13 is perpendicular to the rectangular sliding frame 2. The pressing plate 13 is placed on the rectangular sliding frame 2, and then the pressing nut 15 is tightened downward, so that the pressing plate 13 tightly presses the rectangular sliding frame 2. Then the crane hoists the reinforcement cage 4 and places the reinforcement cage 4 in the slot hole. If the foundation pit is deep, the reinforcement cage 4 needs to be butt-jointed. At this time, the support block 3 can be slid forward so as to pass through the gap between the adjacent vertical reinforcement bars of the reinforcement cage 4, and the support block 3 abuts against the side wall of the guide wall 1 on the other side. The pin column 8 and the pin 10 are inserted so that the support block 3 cannot slide forward and backward. Then the reinforcement cage 4 is placed downward, and the inverted U-shaped ring 24 welded on the reinforcement cage 4 is hung on the support block 3. At this time, another reinforcement cage 4 is hoisted so as to butt-joint the two reinforcement cages 4. When the workers butt-joint the upper and lower reinforcement cages 4, the pin column 8 and the pin 10 are pulled out, the support block 3 is slid backward, and the support block 3 is withdrawn from the reinforcement cage 4. The reinforcement cage 4 is continuously placed downward. When the last reinforcement cage 4 is placed downward, the support block 3 is slid forward again so as to pass through the vertical reinforcement bars of the reinforcement cage 4 and abut against the side wall of the guide wall 1 on the other side. The pin column 8 and the pin 10 are inserted, and the reinforcement cage 4 is placed downward so that the inverted U-shaped ring 24 of the uppermost reinforcement cage 4 is hung on the support block 3. At this time, the support plate 16 is fixed on the adjacent support blocks 3, and two support blocks 3 and a support plate 16 are shown in the drawing. Then the guide pipe 25 is placed in the positioning hole 19, the moving screw rod 21 is moved toward the guide pipe 25, the two half circular clamps 22 clamp the guide pipe 25, the bolts are tightened so that the two half circular clamps 22 tightly clamp the guide pipe 25, the nut on the moving screw rod 21 is tightened, and the guide pipe 25 is fixed. Then the concrete is poured.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some technical features can be replaced by equivalents. Such modifications or replacements do not change the essence of the corresponding technical solutions beyond the spirit and scope of the technical solutions of the embodiments of the present application.
