Description

Technical Field

[0001] This utility model relates to the field of foundation pit technology, specifically to a foundation pit support structure. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plan dimensions. Before excavation, an excavation plan should be determined based on geological and hydrological data and the condition of nearby buildings, and waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope, and the slope should be determined according to relevant construction regulations. For deeper excavations or those near buildings, excavation pit wall support methods, shotcrete wall protection methods, and even methods such as diaphragm walls and interlocking column-type bored piles can be used to prevent the outer soil layer from collapsing. For excavations without the influence of nearby buildings, the wellpoint method can be used to lower the groundwater level, and open excavation with slope protection can be adopted. In cold regions, natural freezing methods can be used for excavation, etc.

[0003] Existing foundation pit excavation requires a support device to support the pit wall. However, when anchoring existing support devices, construction workers need to go into the water to work. However, working in the water can easily lead to drowning, and the silt and gravel at the bottom of the water can easily cause slips or falls. Based on the shortcomings of existing technology, this utility model designs a foundation pit support structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a foundation pit support structure that has the advantage of eliminating the need for construction workers to go into the water for anchoring.

[0005] This utility model provides the following technical solution: a foundation pit support structure, including a support plate, an operating platform fixedly installed on one side of the outer surface of the support plate, and two anchoring structures symmetrically installed on one side of the outer surface of the support plate; the two anchoring structures include limiting groove frames, threaded rods rotatably installed inside the two limiting groove frames, threaded blocks threadedly installed on the outer surface of the two threaded rods, hinge seats fixedly installed on one side of the two threaded blocks, anchoring rods hingedly installed inside the two hinge seats, and anchoring claws fixedly installed at one end of the two anchoring rods.

[0006] As a preferred embodiment of this utility model, the bottom of the support plate is fixedly equipped with multiple teeth, and the outer surfaces of the support plate are fixedly equipped with reinforcing rods.

[0007] As a preferred embodiment of this invention, one end of each of the two reinforcing rods is fixedly connected to the operating platform.

[0008] As a preferred embodiment of this utility model, the support plate has an internal cavity, and a water inlet mesh is provided between the multiple teeth.

[0009] As a preferred embodiment of this utility model, a first fastener is fixedly installed on one side of the outer surface of the support plate.

[0010] As a preferred technical solution of this utility model, a second fastener is fixedly installed on the other side of the outer surface of the support plate, and the second fastener and the first fastener can be tightly engaged.

[0011] As a preferred embodiment of this utility model, a connecting rod is fixedly installed at one end of the two threaded rods that pass through the limiting groove frame, and the two connecting rods are rotatably connected to the operating platform.

[0012] As a preferred embodiment of this utility model, a hexagonal slotted bolt is fixedly installed at one top end of each of the two connecting rods.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This foundation pit support structure, through the anchoring structure, allows construction workers to insert the support plate into the foundation pit during the support process. The construction workers then use a hexagonal wrench inserted into the hexagonal slot bolt to rotate it. This causes the connecting rod to rotate the threaded rod inside the limiting slot frame, thereby allowing the threaded block to move the hinge seat downwards horizontally on the outer surface of the threaded rod. Due to the hinge between the anchor rod and the hinge seat, as the hinge seat moves downwards, it can cause the anchor rod to continuously and obliquely insert into the bottom of the pit. The anchoring claws can then anchor it, thus achieving the goal of anchoring without requiring construction workers to go into the water, thereby improving the safety of the device construction.

[0015] 2. In this foundation pit support structure, water can enter the interior of the support plate through multiple water inlets during the insertion of the support plate into the foundation pit, thereby increasing the weight of the support plate and thus improving the stability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A foundation pit support structure includes a support plate 1. An operating platform 2 is fixedly installed on one side of the outer surface of the support plate 1. Two anchoring structures 3 are symmetrically installed on one side of the outer surface of the support plate 1. The two anchoring structures 3 include limiting groove frames 31. Threaded rods 32 are rotatably installed inside the two limiting groove frames 31. Threaded blocks 33 are threadedly installed on the outer surface of the two threaded rods 32. Hinged seats 34 are fixedly installed on one side of the two threaded blocks 33. Anchor rods 35 are hingedly installed inside the two hinged seats 34. Anchor claws 36 are fixedly installed at one end of the two anchor rods 35.

[0024] Please see Figure 1 and Figure 5 Multiple teeth 4 are fixedly installed on the bottom of the support plate 1, and reinforcing rods 5 are fixedly installed on both sides of the outer surface of the support plate 1. One end of each reinforcing rod 5 is fixedly connected to the operating platform 2. There is a cavity inside the support plate 1, and a water inlet screen 6 is provided between the multiple teeth 4. A first fastener 7 is fixedly installed on one side of the outer surface of the support plate 1. A second fastener 8 is fixedly installed on the other side of the outer surface of the support plate 1, and the second fastener 8 and the first fastener 7 can be tightly engaged.

[0025] During the insertion of the support plate 1 into the foundation pit via the water inlet net 6, water can enter the interior of the support plate 1 through multiple water inlet nets 6, thereby increasing the weight of the support plate 1 and improving the stability of the device. The first fastener 7 and the second fastener 8 ensure a tighter fit at the joints when anchoring multiple support plates 1.

[0026] Please see Figure 3-4 Two threaded rods 32 are fixedly installed with connecting rods 37 at one end through the limiting groove frame 31. The two connecting rods 37 are rotatably connected to the operating platform 2. Hexagonal slotted bolts 38 are fixedly installed at the top end of the two connecting rods 37.

[0027] By inserting a hexagonal wrench into the hexagonal slot bolt 38 and rotating it, the connecting rod 37 can drive the threaded rod 32 to rotate inside the limiting slot frame 31, thereby allowing the threaded block 33 to drive the hinge seat 34 to move horizontally downward on the outer surface of the threaded rod 32.

[0028] Working principle: When a foundation pit support structure is used, the support plate 1 is first placed in the water by a crane, so that the teeth 4 are inserted into the mud. At the same time, water can enter the interior of the support plate 1 through multiple water inlet nets 6, thereby increasing the weight of the support plate 1 and improving the stability of the device. Then, the construction workers insert a hexagonal wrench into the hexagonal slot bolt 38 and rotate it, which causes the connecting rod 37 to drive the threaded rod 32 to rotate inside the limiting slot frame 31. This allows the threaded block 33 to drive the hinge seat 34 to move horizontally downward on the outer surface of the threaded rod 32. Due to the hinge between the anchor rod 35 and the hinge seat 34, when the hinge seat 34 moves downward, it can drive the anchor rod 35 to continuously insert obliquely into the bottom of the pit. It can be anchored by the anchor claw 36. At the same time, the first fastener 7 and the second fastener 8 can make the connection of multiple support plates 1 fit better when anchoring them.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
