Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically a support device for emergency repair pits. Background Technology

[0002] Emergency repair pits are temporary pits dug during emergency repairs to repair damaged facilities or equipment. To ensure the safety of underground structure construction and the surrounding environment of the emergency repair pit, construction workers will set up support devices such as retaining walls to maintain the stability of the pit wall soil during the excavation process. This provides a safe working space for earthwork excavation and underground construction, and prevents the emergency repair pit from collapsing or landslideing.

[0003] When using existing emergency repair pit support devices, taking the common support baffle as an example, construction workers use the support baffle and bolts and other fasteners to support the pit walls. However, since most support baffles are one-piece structures, they occupy a large area and are cumbersome to handle and disassemble. They cannot be quickly assembled according to construction needs, which is not conducive to the excavation of emergency repair pits. Utility Model Content

[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 As shown, a support device for an emergency repair pit includes support baffles 1, with at least two support baffles 1 provided. It should be noted that there must be at least one pair of support baffles 1. In actual use, workers can extend the support baffles 1 laterally, longitudinally, and vertically according to the actual conditions of the emergency repair pit. Compared with common integrated support structures, this utility model uses a multi-piece splicing method for assembly, offering higher flexibility and facilitating transportation and manual handling. Side baffles 2 are vertically provided on all four sides of the support baffles 1, with one side of each side baffle 2 connected to the support baffle 1. Reinforcing components are also included. 3. Two channel steel seats 5 are symmetrically installed on one side of the support baffle 1, and the reinforcement component 3 is set on the outside of the support baffle 1. After the support baffle 1 is assembled, its splicing strength can be improved, thereby effectively enhancing the support performance of the support baffle 1. The channel steel seat 5 is equipped with a quick-release support component 6 that allows the support baffle 1 to fit against the wall of the emergency repair pit. By setting the support component 6, it can be supported from between the two opposing support baffles 1, so that the outer side of the support baffle 1 can fit tightly against the wall of the emergency repair pit, thus effectively reducing the probability of the emergency repair pit collapsing or landslide.

[0024] The reinforcement component 3 includes a reinforcing steel pipe 31 disposed on one side of the support baffle 1. The side baffle 2 has insertion holes 32 corresponding to the reinforcing steel pipe 31 inside. The reinforcing steel pipe 31 is connected to the insertion holes 32 at both ends, such as... Figure 1 , Figure 3 As shown, by setting the insertion round hole 32, the installation of the reinforcing steel pipe 31 can be made more convenient. Furthermore, by utilizing the reinforcing steel pipe 31, the bending resistance of the support baffle 1 can be effectively enhanced, and the overall splicing strength can be improved after the support baffle 1 is assembled.

[0025] A U-shaped channel steel plate 4 is provided between the channel steel seats 5. One side of the U-shaped channel steel plate 4 is connected to the support baffle 1. By setting the U-shaped channel steel plate 4 and cooperating with the reinforcement component 3, the overall splicing strength of the support baffle 1 can be further improved.

[0026] Support assembly 6 includes a support sleeve 61 disposed between the channel steel seats 5. An inner rod 62 is coaxially and slidably inserted inside the support sleeve 61. The channel steel seat 5 has at least two support plates 63 inside, each support plate 63 being connected to both sides of the inner wall of the channel steel seat 5. Figure 1 , Figure 4 and Figure 5 As shown, by setting the supporting sleeve 61 and the inner rod 62 of the sleeve, the two opposing support baffles 1 can be tightly fitted to the inner walls of the emergency repair pit. This can effectively reduce the probability of the emergency repair pit collapsing or landslide, and help improve the safety of construction personnel inside the emergency repair pit.

[0027] A locking pin 8 perpendicular to one end of the supporting sleeve 61 is provided on its outer side, and a fixing groove 7 corresponding to the locking pin 8 is provided on the outer surface of the inner rod 62 of the sleeve. Figure 3 , Figure 4 As shown, by setting locking pins 8 and fixing grooves 7, it is convenient for staff to adjust the extension length of the inner rod 62 of the inner sleeve of the supporting sleeve 61 according to the actual width of the emergency repair pit, thus improving applicability.

[0028] One end of the supporting sleeve 61 and one end of the inner rod 62 of the sleeve are both fixedly connected to a limiting seat 10. The limiting seat 10 is located above the support plate 63. The support plate 63 has a mounting hole 9 inside. The limiting seat 10 has a positioning bolt 11 inside. The bottom end of the positioning bolt 11 extends through to the outside of the mounting hole 9 and is screwed with a fastening nut 12. Figure 1 , Figure 2 and Figure 4 As shown, after the limiting seat 10 at one end of the supporting sleeve 61 and the inner rod 62 of the sleeve enters the channel steel seat 5, the supporting component 6 and the two end support plates 63 can be connected by the positioning bolt 11 and the fastening nut 12, which can enhance the assembly strength between the supporting component 6 and the support baffle 1, and make the splicing assembly of the support baffle 1 more stable.

[0029] Each side baffle 2 has a strip-shaped sealing gasket 13 fixedly connected to its outer wall. The strip-shaped sealing gasket 13 is made of rubber or silicone material. Figure 1 , Figure 3 As shown, after the support baffle 1 is assembled, the strip sealing gasket 13 between adjacent side baffles 2 can effectively block the intrusion of water vapor in the soil, thus improving the overall sealing performance of the support baffle 1.

[0030] Working principle: First, workers can expand the support baffle 1 horizontally, longitudinally, and vertically according to the actual situation of the repair pit. Compared with the common integrated support structure, this utility model adopts a multi-piece splicing method for assembly, which is more flexible and convenient for transportation and manual handling. Then, the supporting component 6 can make the two opposing support baffles 1 fit tightly against the inner walls of the repair pit, which can effectively reduce the probability of collapse or landslide in the repair pit and improve the safety of construction workers inside the repair pit. After the support baffle 1 is assembled, the reinforcing component 3 can effectively enhance the bending resistance of the support baffle 1 and improve the overall splicing strength after the support baffle 1 is assembled.
