Description

Technical Field

[0001] This utility model relates to the field of foundation pit technology, and in particular to foundation pit protection devices. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings. 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 large excavation pits may use methods such as diaphragm walls and interlocking column-type bored piles to prevent the outer soil layer from collapsing. If there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and open excavation with slope protection can be adopted. In cold regions, natural cold air freezing methods can be used for excavation, etc.

[0003] Protective devices can effectively protect the area around the foundation pit and reduce safety hazards for pedestrians. However, the existing technical problems are: the connection points of existing municipal road foundation pit protective devices are mostly directly fixed, which cannot be effectively adjusted according to the size of the foundation pit. In addition, the road surface of the foundation pit is mostly muddy with varying slopes, and the bottom support of the protective device cannot be adjusted in height and has poor grip, which increases the difficulty of operation for construction workers and makes it inconvenient for them to use. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a foundation pit protection device.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] A foundation pit protection device includes a baffle with four slots. Grooves are formed on both the left and right sides near the top of the baffle. Bases are located on the bottom of the baffle near both the left and right sides. A first threaded rod is fixedly connected to the top of each base. First threaded holes are formed on the bottom of the baffle near both the left and right sides. The top of each threaded rod passes through an adjacent first threaded hole. Two horizontal plates are fixedly connected to the right side of the baffle, each with a through hole. A second threaded hole is formed on the top of the baffle near the left side. A second threaded rod passes through the inner cavity of the second threaded hole, and a knob is fixedly connected to the top of the second threaded rod.

[0007] Furthermore, the four slots are arranged symmetrically about the central axis of the baffle, and the grooves are interconnected with the adjacent slots.

[0008] Furthermore, a reflective warning sign is fixedly connected to the front side of the baffle.

[0009] Furthermore, the first screw hole and the adjacent slot are interconnected, and the first screw hole and the first threaded rod are connected by a thread.

[0010] Furthermore, the top end of the first threaded rod is provided with a fixing plate, which is fixedly connected to the adjacent slotted inner cavity. The top of the fixing plate is provided with a round hole, which matches the second threaded rod.

[0011] Furthermore, the second screw hole and the adjacent slot are interconnected, the second screw hole and the second threaded rod are threadedly connected, and the through hole and the second threaded rod are matched.

[0012] Furthermore, the bottom of the base is fixedly connected with a number of fixing nails, which are arranged in a circular array.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a pit protection device, including a baffle 1, a reflective warning sign 2 fixedly connected to the front side of the baffle 1, four slots 3 on the baffle 1, and grooves 4 on the left and right sides near the top of the baffle 1. The four slots 3 are symmetrically arranged about the central axis of the baffle 1. The grooves 4 are interconnected with the adjacent slots 3. The bottom of the baffle 1 is provided with a base 5 near the left and right sides. The bottom of the base 5 is fixedly connected with a number of fixing nails 6, which are arranged in a ring array. The top of the base 5 is fixedly connected with a first threaded rod 7. The bottom of the baffle 1 is provided with a first screw hole 8 near the left and right sides. The top of the first threaded rod 7 passes through the adjacent first screw hole 8. The first screw hole 8 is interconnected with the adjacent slot 3. The first screw hole 8 and the first threaded rod 7 are connected by a thread.

[0025] Two horizontal plates 9 are fixedly connected to the right side of the baffle 1. A through hole 10 is provided on the horizontal plate 9. A second screw hole 12 is provided on the top of the baffle 1 near the left side. A second threaded rod 11 is provided through the inner cavity of the second screw hole 12. A knob 13 is fixedly connected to the top of the second threaded rod 11. The second screw hole 12 is interconnected with the adjacent slot 3. The second screw hole 12 and the second threaded rod 11 are threaded together. The through hole 10 matches the second threaded rod 11. A fixing plate 14 is provided at the top of the first threaded rod 7. The fixing plate 14 is fixedly connected to the inner cavity of the adjacent slot 3. A round hole 15 is provided on the top of the fixing plate 14. The round hole 15 matches the second threaded rod 11.

[0026] Working principle: In the process of using this foundation pit protection device, the baffle 1 is moved to the vicinity of the foundation pit. Then, according to the different slopes of the ground, the height of the corresponding base 5 is adjusted. When adjusting the height of the base 5, the distance between the base 5 and the baffle 1 is adjusted. The base 5 is rotated, and the base 5 drives the first threaded rod 7 to rotate in the inner cavity of the first threaded hole 8. The first threaded rod 7 moves the adjacent first threaded hole 8, and the first threaded rod 7 drives the base 5 to move, thereby adjusting the distance between the base 5 and the baffle 1. After the adjustment is completed, the baffle 1 is pressed down so that the fixing nail 6 is inserted into the soil, thereby fixing the baffle 1. By adjusting the distance between the base 5 and the baffle 1, this device can be used on ground with different slopes, greatly improving the scope of application.

[0027] When it is necessary to enclose the foundation pit, first fix the first baffle 1 in the manner described above, then move the second baffle 1 and rotate the knob 13 on the second baffle 1. The knob 13 drives the second threaded rod 11 to rotate in the inner cavity of the second threaded hole 12. The second threaded rod 11 moves upward relative to the second threaded hole 12. Then move the second baffle 1 so that the two horizontal plates 9 on the right side of the first baffle 1 are inserted into the inner cavity of the groove 4 on the left side of the second baffle 1. Then rotate the knob 13 on the second baffle 1 so that the second threaded rod 11 moves downward relative to the second threaded hole 12. The second threaded rod 11 passes through the two through holes 10 and is inserted into the inner cavity of the round hole 15, thus completing the connection between the two baffles 1. Then flip the second baffle 1. The second baffle 1 flips around the second threaded rod 11 as the center, thereby adjusting the angle between the two baffles 1, so that the device can effectively adjust the angle within the foundation pit area.
