Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit support, and in particular to a deep foundation pit pile anchor cable support structure. Background Technology

[0002] Deep foundation pit pile and anchor cable support is a common foundation pit support structure, widely used in large-scale underground engineering. Its main function is to prevent the foundation pit from collapsing or deforming during excavation and to ensure the stability of the surrounding environment. This support structure consists of piles, anchor cables and related supporting facilities.

[0003] Piles are constructed by driving reinforced concrete piles into the ground using mechanical equipment to form a retaining wall for the foundation pit, which serves to isolate groundwater and limit soil deformation. Anchor cables, on the other hand, are constructed by installing anchor rods around the foundation pit to connect the external soil to the piles, thereby effectively transmitting soil pressure and enhancing the stability of the support structure. Anchor cables are made of steel strands or reinforced concrete and have strong tensile strength.

[0004] The advantages of this support method are its short construction period and adaptability to complex geological conditions. The piles provide a reliable retaining wall, while the anchor cables provide additional support without taking up too much space. The anchor cables provide reaction tension through two I-beams. However, in traditional construction methods, when installing the I-beams, other support rods or manual support are required to keep the I-beams attached to the foundation pit wall to prevent them from falling off automatically. This wastes manpower and resources and is inefficient. Therefore, a deep foundation pit pile and anchor cable support structure is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a deep foundation pit pile anchor cable support structure, which aims to improve the problem of traditional construction methods where, during the installation of I-beams, other support rods or manual support are needed to keep the I-beams attached to the foundation pit wall to prevent them from falling off automatically, which wastes manpower and resources and is inefficient.

A spring is fixedly connected to the inner wall of the inner shell, and a sliding plate is fixedly connected to the rear end of the spring. A plug is fixedly connected to the rear side of the sliding plate, and a stop is slidably connected inside the inner shell.

[0010] As a further description of the above technical solution:

[0011] The anchor cable body and the I-beam abut against each other, and the cone is slidably connected to the inside of the casing.

[0012] As a further description of the above technical solution:

[0013] The rotating rod is externally rotatably connected to the inside of the pressure block, and the fixing bolt is externally slidably connected to the inside of the cone.

[0037] Working principle: When carrying out support construction in the foundation pit, first, piles 1 are placed around the foundation pit, then the anchor cable body 2 is fixed inside the piles 1, and simultaneously, baffles 3 are installed outside the anchor cable body 2. Next, I-beams 4 are installed outside the anchor cable body 2. By placing the I-beams 4 in the designated position and pushing the pressure block 6, the cone 7 is inserted into the soil under the limiting position of the sleeve 5. Then, an external hex wrench is inserted into the front end of the rotating rod 8 and rotated. The rotating rod 8 drives the turntable 9 to rotate, causing the connecting rod 10 to push the fixing bolt 11 outward, pushing the fixing bolt 11 out of the cone 7 and inserting it into the soil, thus fixing the I-beams 4 to the inner wall of the foundation pit without constant support. Similarly, fix the other I-beam 4 in place, then move the slide plate 16 to compress the spring 15, causing the insertion rod 17 to retract into the inner shell 14. At the same time, the stop block 18 automatically falls down to block the outlet of the insertion rod 17. Next, insert the gusset plate 13 between the two I-beams 4 and let the pin 12 pass through the space between the two I-beams 4 and the gusset plate 13. Finally, pull the stop block 18 upward to disengage the stop block 18 from the insertion rod 17. At this time, the spring 15 will immediately push the slide plate 16 to reset the insertion rod 17 and insert it into the pin 12, fixing the pin 12 in place without welding. This allows the two I-beams 4 to be connected to each other, with the same force, protecting the foundation pit and preventing collapse.
