Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit construction, and more specifically to a foundation pit retaining structure. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. However, the foundation pit retaining structure mainly bears the water pressure and soil pressure generated by the foundation pit excavation unloading, and transfers this pressure to the support. It is a temporary retaining wall structure for stabilizing the foundation pit and preventing the outer soil layer from collapsing.

[0003] After searching, a Chinese patent disclosed a foundation pit retaining structure (authorization announcement number CN 209040127U), which belongs to the technical field of "foundation pit construction" and the protected rights: "including a pile body, on which a diagonal bracing assembly is added: the diagonal bracing assembly includes a convex strip horizontally arranged on the pile body and a diagonal rod pressed against the bottom of the convex strip, and an acute angle is formed between the diagonal rod and the pile body. The utility model arranges the diagonal rod to support the column, thereby improving the structural strength of the pile body."

[0004] The shortcomings of the existing technology: In the existing equipment, although the diagonal bracing assembly can be used to support the pile body, it is adjusted by bolts and threaded holes. If the staff use too much force to tighten the bolts and threaded holes, it is easy to cause thread slippage, which further increases the disassembly time of the equipment, reduces the practicality of the equipment, and is not conducive to actual application and operation. For this reason, we propose a foundation pit retaining structure. Utility Model Content

The card blocks 10 are fixedly installed at the bottom of the first slide 8. The card grooves 11 are equidistantly opened inside the base 1. The bottom ends of the card blocks 10 pass through the inner wall of the slider 5 and extend to the inside of the card groove 11. The first slide grooves 12 are opened on one side of the inner wall of the first receiving groove 7. The interior of the first receiving groove 7 is connected to the interior of the first slide groove 12. The L-shaped blocks 13 are fixedly installed on one side of the first slide 8. The end of the L-shaped blocks 13 away from the first slide 8 is The first lever 14 is connected to the first end of the L-shaped block 13 and is located on the outside of the slider 5. The insertion holes 15 are all opened on one side of the inner wall of the first groove 7 and are located above the first lever 12. The insertion rods 14 cooperate with the insertion holes 15. One end of the screw 3 extends to the outside of the base 1. The turntable 4 is fixedly mounted on one end of the screw 3 and is located on the outside of the base 1. The connecting rod 6 is rotatably connected to the top of the slider 5. The end of the connecting rod 6 away from the slider 5 is rotatably connected to the inner side of the protective pile 2. By manually rotating the turntable 4, the screw 3 is driven to rotate inside the base 1, thereby driving the slider 5 to slide inside the base 1 and cooperating with the connecting rod 6. When it slides to a certain position, the protective pile 2 is perpendicular to the ground. The insertion rod 14 is manually pulled out from the inside of the insertion hole 15, and then the elastic force of the first spring 9 is used to drive the block 10 at the bottom of the first slide plate 8 to be inserted into the corresponding slot 11 to fix the slider 5 and further fix the angle of the protective pile 2.

[0026] Furthermore, the scale assembly includes a pointer 16 and a scale line 17. The scale line 17 is arranged on one side of the top of the base 1.

When the slider 5 slides inside the base 1, it drives the pointer 16 to slide on the scale line 17 on one side of the top of the base 1. When the scale value is larger, the flipping angle of the protective pile 2 is larger, so that the staff can clearly know that the pointer 16 stops after moving to a certain value, thereby accelerating the effect of flipping the protective pile 2.

[0027] Furthermore, the grip assembly includes a second groove 18, a second slide 19, a second slide 20, a pull plate 21, a connecting plate 22, a cone plate 23 and a second spring 24. The second groove 18 is opened inside the protective pile 2, the second slide 19 is opened on one side of the inner wall of the second groove 18, the second groove 18 is communicated with the second slide 19, the second slide 20 is slidably connected to the inside of the second groove 18, the connecting plate 22 is fixedly installed at the bottom of the second slide 20, the bottom of the connecting plate 22 passes through the notch opened at the bottom of the inner wall of the second groove 18 and extends to the bottom of the protective pile 2, the cone plate 23 is fixedly installed at the bottom of the connecting plate 22, the second spring The two ends of 24 are fixedly connected to the top of the inner wall of the second containing groove 18 and the top of the second slide 20 respectively. The pull plate 21 is fixedly installed at one end of the second slide 20. The end of the pull plate 21 away from the second slide 20 passes through the inside of the second slide groove 19 and extends to the outside of the protective pile 2. When the protective pile 2 is perpendicular to the ground, the staff releases the pull plate 21 and uses the elastic force of the second spring 24 to drive the connecting plate 22 at the bottom of the second slide 20 to slide downward inside the second containing groove 18, thereby driving the cone plate 23 to move downward, so that the cone plate 23 is inserted into the soil, thereby fixing the protective pile 2 and enhancing the stability of the protective pile 2.

[0028] Furthermore, the early warning component includes a second spring 24 and a controller 25. The second spring 24 is fixedly mounted on the top of the protective pile 2, and the controller 25 is fixedly mounted on the outside of the base 1 and is located on one side of the turntable 4. The controller 25 is electrically connected to the second spring 24. By driving the controller 25, the second spring 24 is driven to respond, thereby issuing an early warning to nearby non-staff members to prevent them from falling into the foundation pit.

[0029] Furthermore, pads 26 are fixedly installed at the four corners of the bottom of the base 1, and the elastic force of the second spring 24 is greater than the sum of the gravity of the second slide 20, the pull plate 21, the connecting plate 22 and the cone plate 23. By setting the pads 26, the bottom of the base 1 is stably supported, and the equipment is further stably supported. By setting the elastic force of the second spring 24 to be greater than the sum of the gravity of the second slide 20, the pull plate 21, the connecting plate 22 and the cone plate 23, the stability of the protective pile 2 is improved.

[0030] The working principle of the present invention is as follows: the staff first places the base 1 at the designated position of the foundation pit, and then manually rotates the turntable 4, thereby driving the screw 3 to rotate inside the base 1, and then driving the slider 5 to slide inside the base 1, and cooperates with the connecting rod 6 to drive the protective pile 2 to flip, and at the same time drives the pointer 16 to slide against the scale line 17 on the top side of the base 1. When it slides to a certain position, the protective pile 2 is perpendicular to the ground. Then the insertion rod 14 is manually pulled out from the inside of the insertion hole 15, and then the elastic force of the first spring 9 is used to drive the block 10 at the bottom of the first slide plate 8 to be inserted into the corresponding slot 11 to fix the slider 5 and further fix the angle of the protective pile 2. Then, the staff releases the pull plate 21 and uses the elastic force of the second spring 24 to drive the connecting plate 22 at the bottom of the second slide plate 20 to slide downward inside the second receiving groove 18, thereby driving the cone plate 23 to move downward, so that the cone plate 23 is inserted into the soil, thereby fixing the protective pile 2, enhancing the stability of the protective pile 2, and increasing the practicality of the equipment, and completing the foundation pit enclosure work.
