Description

Technical Field

[0001] This utility model belongs to the field of foundation pit support technology, specifically, it relates to a foundation pit support device for building construction. Background Technology

[0002] In building construction projects, foundation pit support is a crucial step in ensuring construction safety and the stability of the surrounding environment. With the advancement of urbanization, the depth and scale of building foundation pits are constantly increasing, placing higher demands on the stability, reliability, and adaptability of support devices. However, in the process of operating existing technologies, the inventors have discovered the following problems:

[0003] The prior art discloses a composite retaining wall for foundation pit support in building construction (202411123713.7), which includes a first retaining wall base block. The surface of the first retaining wall base block has an elongated hole. A threaded collar is fixedly installed inside the elongated hole. A first threaded rod is installed in the internal thread of the threaded collar. A long pipe is fixedly installed on the back of the first retaining wall base block. The long pipe and the elongated hole are matched and located on the same straight line. The first threaded rod passes through the long pipe. A round block is rotatably connected to the end of the first threaded rod. A round ring is fixedly connected to the end of the long pipe.

[0004] Existing technology uses retaining walls to block earthen walls. However, this technology fixes the retaining wall by inserting long pipes or other structures into it. But when the earthen wall collapses on a large scale, the long pipes will move synchronously, causing the retaining wall to fail to block the earthen wall. Therefore, existing technology has certain drawbacks.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0033] like Figure 1 As shown, a foundation pit support device for building construction includes:

[0034] The blocking device includes a barrier wall 10. The top wall of the barrier wall 10 has multiple first connecting holes 11 spaced at equal intervals. Each of the multiple first connecting holes 11 has a pin 12 inside its cavity. A drive rod 17 is installed inside the cavity of the pin 12. An annular plate 22 is fixedly installed on the inner side wall of the cavity above the pin 12. The front side wall of the annular plate 22 is hollowed out. A reset plate 24 is installed inside the cavity of the annular plate 22. A pressure plate 21 is fixedly installed on the front side wall of the drive rod 17 at a position below the reset plate 24.

[0035] The connecting device includes four limiting cones 18, each of which is located on one of the four side walls below the drive rod 17. A rotating column 29 is fixedly installed on one side wall of each of the four limiting cones 18. A drive bar 34 is provided on the side wall of each of the multiple rotating columns 29. The side wall of each of the multiple drive bars 34 is fixedly connected to the side wall of the drive rod 17.

[0036] In practical use, by inserting multiple pins 12 into the first connecting hole 11, and then inserting the pins 12 into the ground, the retaining wall 10 is limited. The retaining wall 10 blocks the sand and soil. The multiple limiting cones 18 are unfolded by the connecting device and inserted into the soil to limit the retaining wall 10, thereby improving the stability of the retaining wall 10.

[0037] In summary, by setting up a blocking device and a connecting device, the retaining wall 10 can be fixed by the connecting device, thereby improving the stability of the retaining wall 10. The blocking device blocks the sand and soil through the retaining wall 10, preventing large-scale soil landslides that would render the retaining wall 10 unable to block the soil. It is convenient to use and has a simple structure.

[0038] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a second connecting hole 14 is provided on the side wall of the pin 12, a waterproof plate 13 is fixedly installed on the front side wall of the retaining wall 10, a handle 16 is provided in the cavity of the waterproof plate 13, and a first fixing plate 20 is fixedly installed on the rear side wall of the handle 16. The first fixing plate 20 passes through the retaining wall 10 and the second connecting hole 14, and is movably connected to the penetration of the retaining wall 10 and the second connecting hole 14.

[0039] A first spring 19 is fixedly installed on the rear side wall of the handle 16 at the left and right sides of the first fixing plate 20. The other end of the first spring 19 is fixedly connected to the front side wall of the retaining wall 10. The first fixing plate 20 is located below the reset plate 24.

[0040] A connecting block 25 is fixedly installed on both the left and right side walls of the reset plate 24. A fourth connecting hole 27 is opened on both corresponding side walls inside the cavity of the annular plate 22. A second spring 26 is fixedly connected to the side wall of the two connecting blocks 25 that are far apart from each other and the cavity of the corresponding fourth connecting hole 27. The connecting block 25 is movably installed inside the cavity of the fourth connecting hole 27.

[0041] In practical use, the operator places the pin 12 above the first connecting hole 11 and inserts the pin 12 into the cavity of the first connecting hole 11. During the insertion process, the operator needs to pull the handle 16 forward and then insert the tapered part at the bottom of the pin 12 into the soil. At this time, the operator releases the handle 16, and the handle 16 returns to its original position due to the force of the first spring 19. The first fixing plate 20 is then inserted through the second connecting hole 14 and inserted below the reset plate 24. The operator then continues to press the pin 12 downward. The movement of the pin 12 can drive the annular plate 22 to move. The movement of the annular plate 22 can drive the reset plate 24 to move through the connection between the fourth connecting hole 27 and the connecting block 25. During the movement, the reset plate 24 will rotate due to the obstruction of the front end by the first fixing plate 20. The rotation of the reset plate 24 can drive the pressure plate 21 to move downward. The movement of the pressure plate 21 can drive the drive rod 17 to move downward.

[0042] In summary, by setting up a retaining wall 10, a first connecting hole 11, a pin 12, a waterproof plate 13, a second connecting hole 14, a handle 16, a drive rod 17, a first spring 19, a first fixing plate 20, a pressure plate 21, an annular plate 22, a reset plate 24, a connecting block 25, a second spring 26, and a fourth connecting hole 27, the drive rod 17 moves downwards when the worker inserts the first connecting hole 11 into the cavity of the pin 12, thereby facilitating the operation of the connecting device. By inserting the pin 12 into the soil and connecting it with the first connecting hole 11, the retaining wall 10 can be limited.

[0043] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, multiple second fixing plates 30 are fixedly installed on the inner side wall of the pin 12, and the two side walls of the multiple rotating columns 29 are respectively connected to the second fixing plates 30 in a rotatable manner. A telescopic plate 32 is movably installed in the cavity of each of the multiple fixing cylinders 31, and a connecting rod 33 is fixedly installed on the two side walls of each of the multiple telescopic plates 32.

[0044] Each of the drive bars 34 rotates on the side wall of two corresponding connecting rods 33 that are close to each other. A third spring 28 is fixedly connected between the bottom wall of the drive rod 17 and the bottom wall of the cavity of the pin 12.

[0045] The lower sidewall of the pin 12 has multiple third connecting holes 15 arranged in a ring array, and multiple limiting cones 18 are located in the cavity of the third connecting holes 15.

[0046] In practical use, when the drive rod 17 moves downward, it drives the drive bar 34 downward. The movement of the drive bar 34 drives the connecting rod 33 to move. The connecting rod 33, being larger, drives the telescopic plate 32 to move. The movement of the telescopic plate 32 drives the fixed cylinder 31 to move and rotate. The rotation of the fixed cylinder 31 drives the rotating column 29 to rotate. The rotation of the rotating column 29 drives the limiting cone 18 to rotate. The rotation of the limiting cone 18 allows it to unfold and insert into the soil. The rotatable connection between the strip 34 and the connecting rod 33, and the movable connection between the fixed cylinder 31 and the telescopic plate 32, enable the drive rod 17 to move up and down. When the connection is not needed, the operator pulls the handle 16 to move it forward. The reset plate 24 is reset by the force of the second spring 26, and the drive rod 17 can be reset by the force of the third spring 28. During the reset process, the drive rod 17 pulls the limiting cone block 18 to reset. The second fixed plate 30 limits the rotating column 29, and the third connecting hole 15 limits the limiting cone block 18.

[0047] In summary, by setting the third connecting hole 15, the fourth connecting hole 27, the third spring 28, the rotating column 29, the second fixing plate 30, the fixing cylinder 31, the telescopic plate 32, the connecting rod 33, and the driving bar 34, the limiting cone 18 can be unfolded during the process of the worker inserting the pin 12. The limiting cone 18 limits the pin 12, and the pin 12 limits the retaining wall 10 through the first connecting hole 11, thereby improving the stability of the retaining wall 10. It is convenient to use and has a simple structure.
