Description

Technical Field

[0001] This utility model relates to the technical field of concrete pouring for linear deep foundation pits, and in particular to a device for rapid and continuous construction of concrete for linear deep foundation pits. Background Technology

[0002] In urban utility tunnel projects, the foundation pits are often deep and the volume of concrete is large. When using concrete pump trucks to pour concrete, concrete mixer trucks need to unload the concrete directly into the hopper of the concrete pump truck through the unloading chute. Using concrete pump trucks to transport concrete to the foundation pit is costly and time-consuming.

[0003] In order to reduce the number of times pump trucks are used, lower project costs, and shorten the construction period, this utility model provides a device for rapid and continuous construction of linear deep foundation pit concrete. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a device for rapid and continuous construction of linear deep foundation pit concrete.

[0005] This utility model provides a device for rapid and continuous construction of linear deep foundation pit concrete, which adopts the following technical solution: A device for rapid and continuous construction of concrete in linear deep foundation pits includes a hopper, a second frame that can move along the length of the foundation pit, and a first frame that can slide on the second frame along the width of the foundation pit. The first frame is located above the second frame, the hopper is fixed on the first frame, and a flexible hose is installed below the hopper.

[0006] Optionally, the first frame includes a frame and first legs, with four first legs fixed to the four corners of the bottom of the frame, and first pulleys installed at the bottom of the first legs; The second frame includes a frame plate and two legs. The four second legs are fixed to the four corners of the bottom of the frame plate. The bottom of the second legs is equipped with second pulleys. Two grooves are opened on the frame plate, and the first pulley can roll along the grooves.

[0007] Optionally, a fixed pipe is fixed to the bottom of the hopper, and a connecting pipe is rotatably connected below the fixed pipe, with a flexible hose fixed to the bottom of the connecting pipe.

[0008] Optionally, a connecting sleeve is provided on the outside of the connecting pipe. The connecting sleeve includes a side wall and a top wall. The side wall contacts the outer wall of the connecting pipe, and the top wall is located above the connecting ring, which supports the top wall. A locking bolt is provided on the side wall, which passes through the side wall and is threaded into the connecting pipe.

[0009] Compared with the prior art, the present invention has the following technical effects: The device is securely installed on both sides of the sheet pile. The second frame, in conjunction with the second pulley, can move smoothly along the direction of the linear foundation pit, while the first frame can move flexibly left and right via the first pulley. During construction, a concrete mixer truck unloads concrete into the hopper, and then a flexible hose is used for precise pouring, effectively completing the structural concrete construction task and significantly improving construction efficiency. The absence of a concrete pump truck during construction not only avoids unnecessary resource waste but also helps increase the overall profit of the project. This invention is simple and practical to operate, significantly improves work efficiency, reduces the number of concrete pumping operations, and increases profits. Attached Figure Description

[0012] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This utility model will be described in further detail.

[0013] Reference Figures 1-4 This utility model discloses a device for rapid and continuous construction of linear deep foundation pit concrete, including a hopper 1, a first frame 2 and a second frame 3. The hopper 1 is welded and fixed on the first frame 2, and the second frame 3 is located below the first frame 2.

[0014] The first frame 2 includes a frame 21 and first legs 22. The four first legs 22 are fixed to the four corners of the bottom of the frame 21 respectively. The bottom of the first legs 22 is equipped with first pulleys 23. The hopper 1 is welded to the inner wall of the first frame 2.

[0015] The second frame 3 includes a frame plate 31 and four second legs 32. The four second legs 32 are fixed to the four corners of the bottom of the frame plate 31, and second pulleys 33 are installed at the bottom of each second leg 32. Two grooves 34 are formed on the frame plate 31, allowing the first pulley 23 to roll along the grooves 34. Two sheet piles 4 are installed in the pit, located on opposite sides of the pit, with concrete poured between them. The second pulleys 33 are in contact with the ground 5, with two pulleys 33 located on one side of one sheet pile 4 and the other two on the other side of the other sheet pile 4. The second pulleys 33 can drive the second frame 3 to slide along the length of the pit.

[0016] The first frame 2 can slide left and right along the width of the foundation pit. When concrete from the concrete mixer truck is unloaded into the hopper 1, the first frame 2 needs to move to the edge of the second frame 3 so that the discharge port of the concrete mixer truck is aligned with the hopper 1 on the first frame 2. When pouring concrete for the foundation pit, after the left side of the foundation pit is poured, the first frame 2 can be moved to the upper right side of the foundation pit to pour the right side of the foundation pit, which is convenient and quick. A clearance groove 35 is provided on the frame 21 plate, and the connecting pipe 6 passes through the clearance groove 35.

[0017] A fixed pipe 11 is fixed below the hopper 1, and a connecting pipe 6 is provided below the fixed pipe 11. A connecting ring 12 is fixed on the outer wall of the bottom end of the fixed pipe 11, and a flexible hose 7 is fixedly connected to the bottom of the connecting pipe 6. The inner wall of the connecting pipe 6 is in contact with the outer wall of the connecting ring 12, and the connecting pipe 6 can rotate along the axis of the connecting ring 12.

[0018] A connecting sleeve 61 is provided on the outside of the connecting pipe 6. The connecting sleeve 61 includes a side wall 611 and a top wall 612. The side wall 611 contacts the outer wall of the connecting pipe 6, and the top wall 612 is located above the connecting ring 12, which supports the top wall 612. A locking bolt 613 is provided on the side wall 611. The locking bolt 613 passes through the side wall 611 and is threadedly connected to the connecting pipe 6, thereby fixing the side wall 611 to the connecting pipe 6.

[0019] The device is securely installed on both sides of the sheet pile 4. The second frame 3, in cooperation with the second pulley 33, can move smoothly along the direction of the linear foundation pit, while the first frame 2 can move flexibly in the left and right directions through the first pulley 23. During construction, the concrete mixer truck unloads the concrete material into the hopper 1, and then uses the hose 7 to carry out precise pouring operations, thereby effectively completing the construction task of structural concrete, significantly improving construction efficiency. The construction process does not require the use of a concrete pump truck, which not only avoids unnecessary waste of resources, but also helps to increase the overall profit of the project.

[0020] This invention is reasonable and simple to operate, significantly improving work efficiency. It can reduce the number of concrete pumping operations, increase efficiency, and boost profits.

[0021] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
