Description

Technical Field

[0001] The present application relates to the technical field of bored pile support structures, and specifically to a bored pile support structure for underground engineering under complex geological conditions. Background Art

[0002] Underground bored pile construction is very common in building construction. An essential step in underground bored pile construction is pre-buried casing, which can support the bored hole.

[0003] Existing casings generally need to be butt-jointed by welding, which is rather troublesome and affects the efficiency of the casing butt-jointing installation operation. In addition, under some complex geological conditions, the stability of the casing will generally be threatened, affecting the safety of subsequent bored pile operations. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a bored pile support structure for underground engineering under complex geological conditions, which has the advantages of being able to reinforce the casing, improve the stability and safety of the casing, and facilitate the docking and installation of the casing. It solves the problem that the existing casing generally needs to be docked by welding, which is more troublesome and affects the efficiency of the docking and installation of the casing. In addition, under some complex geological conditions, the stability of the casing will be threatened, affecting the safety of subsequent bored pile operations.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: an underground engineering bored pile support structure under complex geological conditions, comprising a casing, wherein the inner wall of the casing is fixedly connected to two reinforcement plates, and a first reinforcement plate arranged equidistantly is fixedly connected between the two reinforcement plates, and each reinforcement plate is fixedly connected to a second reinforcement plate arranged equidistantly at a top end of the inner wall of the casing, and a slot is provided in the interior of each of the bases, and six equidistantly arranged plug plates are fixedly connected to the bottom of the inner wall of the casing, and the plug plates are slidably plugged into the base through adjacent slots, and each base is slidably connected to two positioning blocks, and each plug plate has two positioning slots inside, and the positioning blocks are slidably plugged into the plug plate through the positioning slots, and each positioning block is fixedly connected to a spring on the side away from the plug plate, and the other end of the spring is fixedly connected to the interior of the base.

[0006] Through the above scheme, since the existing casings generally need to be butted together by welding, which is rather troublesome and affects the efficiency of the butt-jointing installation of the casings, and under some complex geological conditions, the stability of the casings will generally be threatened, affecting the safety of subsequent bored pile operations, by arranging reinforcement sheets, a first reinforcement plate and a second reinforcement plate on the inner wall of the casing, the bearing capacity and stability of the casing are effectively improved, and the safety of subsequent bored pile operations is improved. By arranging a base, a slot, a plug plate, a positioning block, a positioning groove and a spring, adjacent casings can be automatically butted together, which facilitates the butt-jointing installation of the casings, reduces the workload of workers and improves work efficiency.

[0007] Furthermore, the bottom surface of each inserting plate is fixedly connected with a screw rod, the outer circumferential surface of the screw rod is slidably plugged into the interior of the base, and the outer circumferential surface of the screw rod is threadedly connected with a nut.

[0008] Through the above solution, the connection between the plug plate and the base is reinforced by the screw rod and the nut, thereby improving the stability of the connection between the casings.

[0009] Furthermore, each positioning block is fixedly connected to a plug rod on one side away from the plug plate, the outer circumference of the plug rod is slidably plugged into the interior of the base, the outer circumference of the plug rod is fixedly sleeved with a fixed plate, and an auxiliary plate is rotatably plugged into the interior of each base, and the auxiliary plates are respectively located between two adjacent fixed plates.

[0010] Through the above scheme, the auxiliary plate can be rotated to drive the fixed plates on both sides to move outward, prompting the fixed plates to drive the positioning blocks to move toward both sides through the insertion rods, so that the positioning blocks are moved out of the positioning grooves, eliminating the positioning restrictions on the insertion plates, and thus facilitating the disassembly of adjacent casings.

[0011] Furthermore, a limiting ring is fixedly sleeved on the outer circumference of each auxiliary plate, and the outer circumference of the limiting ring is rotatably connected to the interior of the base.

[0012] Through the above solution, the auxiliary plate is restricted to prevent the auxiliary plate from sliding and falling off.

[0013] Furthermore, a docking groove is provided on the upper surface of the casing, and a docking protrusion is fixedly connected to the bottom surface of the casing.

[0014] Through the above solution, the docking groove and the docking protrusion can facilitate the installation of the casing, and can also improve the stability of the connection between the casings.

[0015] Furthermore, a sealing sheet is provided between adjacent protective tubes, and the sealing sheet is located inside the docking groove.

[0016] Through the above solution, the sealing sheet can seal between adjacent protective tubes, thereby improving the sealing effect between adjacent protective tubes.

[0017] Furthermore, the top end of the inner wall of the casing is fixedly connected with six equally spaced butt joints, and the bottom end of the inner wall of the casing is fixedly connected with six equally spaced butt joints, and the butt joints are respectively slidably connected with adjacent butt joints.

[0018] Through the above solution, the butt joint tube and the butt joint rod can limit the relative rotation between the casings, thereby improving the stability of the connection between the casings.

[0019] Furthermore, each positioning block is provided with an inclined surface at the top end of one side close to the plugboard, and two adjacent positioning blocks are symmetrically arranged.

[0020] Through the above scheme, the inserting plate can push the positioning block to move to both sides under the action of the inclined surface at the top of the positioning block during the downward movement. Then the positioning block automatically moves back under the action of the spring and inserts into the positioning groove, automatically completing the connection and installation operation between the casings.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The bored pile support structure for underground engineering under complex geological conditions effectively improves the bearing capacity and stability of the casing and improves the safety of subsequent bored pile operations by arranging reinforcement sheets, a first reinforcement plate and a second reinforcement plate on the inner wall of the casing. By arranging a base, a slot, an insert plate, a positioning block, a positioning groove and a spring, adjacent casings can be automatically docked, which facilitates the docking and installation of the casings, reduces the workload of workers, improves work efficiency, and solves the problem that the existing casing docking and installation is relatively troublesome and, under some complex geological conditions, the stability of the general casing will be threatened, affecting the safety of subsequent bored pile operations.
