Description

Technical Field

[0001] This utility model relates to the field of foundation pit support, specifically to a foundation pit support device for preventing foundation pit collapse. Background Technology

[0002] Foundation pit support refers to the measures taken to support, reinforce, and protect the sidewalls and surrounding environment of the foundation pit to ensure the safety of underground structure construction and the surrounding environment. However, existing foundation pit support devices are relatively rudimentary. In most cases, support plates are used to hold the sidewalls of the foundation pit in place, and a diagonal brace is used to hold the support plates in place. When the foundation pit is deep, the length and size of the support plates are limited and cannot be adjusted, making it difficult to achieve the desired support effect.

[0003] Chinese patent discloses a foundation pit support device for preventing foundation pit collapse (authorization announcement number CN 220746944U). This patented technology can solve the problem that when the foundation pit is deep, the top and bottom of the first fixing rod have a good vertical support effect on the support plate and the side wall of the foundation pit in the height direction, but the middle part of the first fixing rod has a relatively weak support effect on the support plate. If the soil layer in the middle of the foundation pit side wall collapses and squeezes the support plate, it is very easy to cause the middle part of the first fixing rod to bend inward into the foundation pit, which may cause danger.

[0004] In this patent, if the dust in the foundation pit is too large, it can be easily inhaled by the human body and cause harm. Sprinkling water on the ground can easily spill onto the inner wall of the foundation pit, leading to the risk of collapse. Furthermore, it is difficult to detect whether there is a risk of collapse in the foundation pit from the ground. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a foundation pit support device for preventing foundation pit collapse, including a foundation pit and a positioning column. The positioning column is inserted into the bottom of the foundation pit through a first pin. A protective plate is installed on the outer wall of the positioning column through a connecting frame. The bottom of the protective plate is inserted into the bottom of the foundation pit through multiple second pins. A water tank is installed on the upper end face of the positioning column. A water pump is installed at the bottom of the water tank. A spring tube is installed at the bottom of the water pump. A nozzle is installed at the other end of the spring tube.

[0006] Preferably, the outer wall of the positioning column is fitted with a protective cavity, and a nozzle is installed inside the protective cavity by means of a snap-fit ​​connection.

[0007] Preferably, the protective plate has multiple fixing ears installed from top to bottom on the left side end face, with the fixing ears arranged symmetrically at the front and back.

[0008] Preferably, the upper end face of the positioning column is screwed to the bottom of the water tank by a fixing screw, a ring frame is installed on the outer end of the water tank, and fixing frames are symmetrically installed on the left and right sides of the outer wall of the ring frame. The fixing frames are installed on the ground by plugging in.

[0009] Preferably, an upper plate is symmetrically installed on the outer side wall of the positioning column, and a measuring plate is symmetrically installed on the ground. A pressure sensor is embedded in the inner end of the measuring plate, and a display screen is installed on the outer end of the measuring plate. The pressure sensor and the display screen are electrically connected.

[0010] Preferably, the bottom of the connecting frame is equipped with a support column, and the bottom of the support column is in close contact with the bottom of the pit.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model adopts a water tank, spring tube and nozzle structure, which can spray water at the bottom of the foundation pit to effectively reduce dust and prevent the human body from being harmed by inhaling dust when working inside the foundation pit when there is a lot of floating dust.

[0013] 2. This utility model uses a pressure sensor and display screen structure, which can be observed on the ground to determine whether there is a risk of collapse in the foundation pit. This avoids the situation where workers enter the bottom of the foundation pit and find that a sudden collapse has occurred, thus further improving the safety of the operation.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Please see Figures 1-5 This embodiment provides a foundation pit support device for preventing foundation pit collapse, including a foundation pit 1 and a positioning column 2. The positioning column 2 is inserted into the bottom of the foundation pit 1 by a first pin. A protective plate 11 is installed on the outer wall of the positioning column 2 by a connecting frame. The bottom of the protective plate 11 is inserted into the bottom of the foundation pit 1 by multiple second pins. A water tank 12 is installed on the upper surface of the positioning column 2. A water pump 13 is installed at the bottom of the water tank 12. A spring tube 14 is installed at the bottom of the water pump 13. A nozzle 15 is installed at the other end of the spring tube 14. The protective plate 11 supports the foundation pit 1. The side walls are protected against collapse. During operation, the water tank 12 is filled with clean water. When there is a lot of dust in the pit 1, it is easy for people to inhale it and cause harm to their bodies. The water pump 13 is turned on, and people in the pit 1 spray water with the handheld nozzle 15 to effectively reduce dust. The handheld operation can effectively avoid water spraying onto the side walls of the pit 1, which may cause the pit 1 to collapse. The positioning column 2 is arranged at the bottom center of the pit 1, which further improves the anti-collapse effect of the inner side walls of the pit 1.

[0022] The outer wall of the positioning column 2 is equipped with a protective cavity 16, and the nozzle 15 is installed in the protective cavity 16 by snap-fit. During operation, the protective cavity 16 protects the nozzle 15 to prevent dust from adhering to its surface and making it inconvenient to use.

[0023] Multiple fixing ears 17 are installed from top to bottom on the left side of the inner side of the protective plate 11. The fixing ears 17 are symmetrically arranged at the front and back bottoms. When the pit 1 is too deep during operation, workers can climb into the bottom of the pit 1 through the fixing ears 17, which improves the convenience and safety of the operation.

[0024] The upper end face of the positioning column 2 is screwed to the bottom of the water tank 12 by a fixing screw 18. A ring frame 19 is installed on the outer end of the water tank 12. Fixing frames 21 are symmetrically installed on the outer side of the ring frame 19. The fixing frames 21 are installed on the ground by plugging. During operation, the fixing screw 18 structure is used to facilitate the disassembly of the water tank 12. The ring frame 19 supports the outer side of the water tank 12 to prevent the water tank 12 from tipping over.

[0025] The positioning column 2 has upper plates 22 symmetrically installed on its outer side wall, and measuring plates 23 symmetrically installed on the ground. A pressure sensor 24 is embedded in the inner end of the measuring plate 23, and a display screen 25 is installed on the outer end of the measuring plate 23. The pressure sensor 24 and the display screen 25 are electrically connected. When the positioning column 2 shifts during operation, the upper plate 22 on one side presses against the inner end of the measuring plate 23. The pressure sensor 24 senses the value and displays it on the display screen 25. Workers can observe the display screen 25 on the ground to determine whether there is a risk of collapse in the foundation pit 1. This avoids the situation where workers enter the bottom of the foundation pit 1 and find that a sudden collapse has occurred, further improving the safety of the operation.

[0026] The bottom of the connecting frame is equipped with a support column 26. The bottom of the support column 26 is close to the bottom of the pit 1. When working, the support column 26 exerts pressure on the positioning column 2, thereby improving the anti-collapse effect of the positioning column 2.

[0027] During actual operation, the water tank 12 is filled with clean water. When there is a lot of dust in the pit 1, it is easy for people to inhale it and cause harm to their bodies. The water pump 13 is turned on, and people in the pit 1 spray water with the handheld nozzle 15 to effectively reduce dust. The handheld operation can effectively avoid water spraying onto the side wall of the pit 1, which may cause the pit 1 to collapse. The positioning column 2 is arranged at the center of the bottom of the pit 1, which further improves the anti-collapse effect on the inner side wall of the pit 1.

[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
