Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit construction technology in civil engineering, specifically to a slope protection structure for deep foundation pit construction in civil engineering. Background Technology

[0002] In civil engineering construction, the construction of deep foundation pits is extremely common. During the construction of deep foundation pits, if the surrounding slopes lack effective protection, situations such as soil collapse and landslides are very likely to occur. This will not only seriously affect the construction progress, but may also pose a huge threat to the life safety of construction workers and the stability of surrounding buildings. At present, existing slope protection structures have many problems that urgently need to be solved. Some traditional protection structures, such as the simple method of stacking sandbags, have seriously insufficient protective strength and are difficult to withstand large soil pressure. In extreme situations such as heavy rainfall and earthquakes, the protective effect is greatly reduced, and it is impossible to effectively guarantee construction safety.

[0003] According to the patent application published on the Internet, the inclined protective structure for deep foundation pit construction includes "protective plate, second mounting base, second manual telescopic rod" to achieve the protective work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] The inclined slope protection structure for this deep foundation pit construction utilizes protective plates, a second mounting base, and a second manual telescopic rod to achieve protection. While this structure protects the inclined slope using the protective plates, it can only ensure the stability of the plates and cannot adjust their angle according to the slope's inclination. Furthermore, the protective plates must remain vertical, preventing proper contact between the plates and the slope and thus affecting the protective effect. Therefore, improvements to this structure are necessary. Utility Model Content

[0006] The purpose of this utility model is to provide a slope protection structure for deep foundation pit construction in civil engineering, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a slope protection structure for deep foundation pit construction in civil engineering, including a fixed foot, a base fixedly connected to the top of the fixed foot, a protective mechanism provided on the top of the base, and a counterweight mechanism provided inside the protective mechanism;

[0008] The protective mechanism includes a fixed frame, which is fixedly connected to the top of the base. A support frame is fixedly connected to the left side of the fixed frame, and the support frame is fixedly connected to the top of the base. A threaded rod is rotatably connected inside the fixed frame, and an adjusting disc is fixedly connected to the top of the threaded rod. A movable seat is threadedly connected to the outer periphery of the threaded rod, and the movable seat is slidably connected inside the fixed frame. A first connecting frame is fixedly connected to the left side of the movable seat, and a telescopic shaft is rotatably connected inside the first connecting frame. A second connecting frame is rotatably connected inside the telescopic shaft, and a protective plate is fixedly connected to the left side of the second connecting frame. The bottom of the protective plate is rotatably connected to the inside of the support frame.

[0009] Preferably, the first connecting frame, telescopic shaft, second connecting frame, protective plate and support frame are provided in two sets. The two sets of the first connecting frame, telescopic shaft, second connecting frame, protective plate and support frame are symmetrically distributed on the left and right sides of the movable seat, so that by setting two sets, the slopes on the left and right sides of the deep foundation pit can be protected at the same time.

[0010] Preferably, the fixed frame has a sliding groove inside, and the movable seat is slidably connected in the sliding groove, so as to ensure the stability of the movable seat movement under the action of the sliding groove.

[0011] Preferably, eight fixing feet are provided, and the eight fixing feet are symmetrically distributed at the bottom of the base, so as to facilitate the fixing of the base to the inside of the deep foundation pit.

[0012] Preferably, the counterweight mechanism includes a fixed base, which is fixedly connected to the right side of the protective plate. An installation block is slidably connected inside the fixed base. A counterweight block is fixedly connected to the right side of the installation block. Handles are fixedly connected to the front and rear sides of the counterweight block. A limit shaft is inserted inside the fixed base. A fixing ring is rotatably connected to the periphery of the limit shaft. The fixing ring is threaded inside the fixed base.

[0013] Preferably, the limiting shaft passes through the interior of the mounting block, and the fixing seat and the mounting block are provided with limiting grooves, with the two limiting grooves corresponding to each other. The limiting shaft is inserted into the limiting groove, which facilitates the stability between the fixing seat and the mounting block under the action of the limiting shaft, and at the same time facilitates the installation and disassembly of the counterweight.

[0014] Preferably, the limiting shaft has a rotating groove inside, and the fixing ring is rotatably connected in the rotating groove, which facilitates the stability of the fixing ring under the action of the rotating groove.

[0015] Compared with the prior art, this utility model provides a slope protection structure for deep foundation pit construction in civil engineering, which has the following beneficial effects:

[0016] 1. The inclined slope protection structure for deep foundation pit construction utilizes a protective mechanism. When slope protection is required during deep foundation pit construction, eight symmetrically distributed fixed feet at the bottom of the base are inserted into the center of the area requiring protection within the foundation pit. Rotating the adjusting disc drives the threaded rod to rotate, causing the movable seat to slide up and down within the groove of the fixed frame. The linkage of the first connecting frame, the telescopic shaft, and the second connecting frame allows the protective plate to rotate around the support frame, flexibly adjusting the inclination angle of the protective plate. This allows for rapid adjustment of the protective plate angle according to the specific needs of deep foundation pit construction and the actual terrain, effectively covering the edges of foundation pits of different heights and slopes. This significantly improves adaptability and versatility, meeting diverse construction protection scenarios. The two symmetrically distributed sets of the first connecting frame, telescopic shaft, second connecting frame, protective plate, and support frame can simultaneously protect the symmetrical inclined slopes on both sides of the foundation pit, effectively resisting lateral pressure and soil collapse impacts that may occur during foundation pit construction.

[0017] 2. The inclined slope protection structure for deep foundation pit construction utilizes a counterweight mechanism. During the construction process, when the slope is protected by the protective plate, the counterweight is installed by sliding the mounting block inside the fixed base. Simultaneously, the limiting shaft is inserted into the fixed base and the mounting block. During insertion, rotating the fixing ring allows it to be threaded into the fixed base, ensuring the stability of the limiting shaft. This allows for the simultaneous installation and removal of the counterweight. In the deep foundation pit construction environment, due to complex geological conditions, there may be groundwater flow and disturbance of the surrounding soil, which can easily generate lateral thrust on the protective plate. With the addition of counterweights, the protective plate's ability to resist these external forces is greatly enhanced, making it less prone to overturning or sliding, effectively maintaining the stability of the protective structure.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-6 This utility model provides a technical solution: a slope protection structure for deep foundation pit construction in civil engineering, including a fixed foot 1, a base 2 fixedly connected to the top of the fixed foot 1, a protective mechanism 3 set on the top of the base 2, and a counterweight mechanism 4 set on the inner side of the protective mechanism 3.

[0031] The protective mechanism 3 includes a fixed frame 31, which is fixedly connected to the top of the base 2. A support frame 34 is fixedly connected to the left side of the fixed frame 31, and the support frame 34 is fixedly connected to the top of the base 2. A threaded rod 32 is rotatably connected inside the fixed frame 31. An adjusting plate 35 is fixedly connected to the top of the threaded rod 32. A movable seat 33 is threadedly connected to the outer periphery of the threaded rod 32. The movable seat 33 is slidably connected inside the fixed frame 31. A first connecting frame 36 is fixedly connected to the left side of the movable seat 33. A telescopic shaft 37 is rotatably connected inside the first connecting frame 36. A second connecting frame 38 is rotatably connected inside the telescopic shaft 37. A protective plate 39 is fixedly connected to the left side of the second connecting frame 38. The bottom of the protective plate 39 is rotatably connected to the inside of the support frame 34.

[0032] Two sets of the first connecting frame 36, telescopic shaft 37, second connecting frame 38, protective plate 39 and support frame 34 are provided. The two sets of the first connecting frame 36, telescopic shaft 37, second connecting frame 38, protective plate 39 and support frame 34 are symmetrically distributed on the left and right sides of the movable seat 33, so that by setting two sets, the slopes on the left and right sides of the deep foundation pit can be protected at the same time.

[0033] The fixed frame 31 has a sliding groove inside, and the movable seat 33 is slidably connected in the sliding groove, which makes it easy to ensure the stability of the movement of the movable seat 33 under the action of the sliding groove. There are eight fixed feet 1, which are symmetrically distributed at the bottom of the base 2, so that the base 2 can be fixedly connected to the inside of the deep foundation pit through the fixed feet 1.

[0034] Example 2

[0035] Please see Figure 1-6 Furthermore, based on Embodiment 1, the counterweight mechanism 4 includes a fixed base 41, which is fixedly connected to the right side of the protective plate 39. An installation block 42 is slidably connected inside the fixed base 41. A counterweight block 43 is fixedly connected to the right side of the installation block 42. Handles 44 are fixedly connected to the front and rear sides of the counterweight block 43. A limiting shaft 45 is inserted inside the fixed base 41. A fixing ring 46 is rotatably connected to the periphery of the limiting shaft 45. The fixing ring 46 is threaded inside the fixed base 41. The limiting shaft 45 passes through the interior of the installation block 42. Limiting grooves are opened inside the fixed base 41 and the installation block 42, and the two limiting grooves correspond to each other. The limiting shaft 45 is inserted into the limiting groove, which facilitates the stability between the fixed base 41 and the installation block 42 under the action of the limiting shaft 45, and at the same time facilitates the installation and disassembly of the counterweight block 43.

[0036] In actual operation, when this device is used, and when slope protection is required during the construction of a deep foundation pit, firstly, insert the eight fixed feet 1 symmetrically distributed at the bottom of the base 2 into the middle of the position in the deep foundation pit that needs protection, ensuring that the base 2 and the fixed frame 31 are in a stable state. By rotating the adjusting plate 35, the threaded rod 32 is rotated, causing the movable seat 33 to slide up and down in the groove of the fixed frame 31. The movable seat 33 drives the first connecting frame 36 to move, which causes the telescopic shaft 37 to change angle inside the first connecting frame 36 and the second connecting frame 38, and to move simultaneously. This allows the telescopic shaft 37 to drive the second connecting frame 38 and the protective plate 39 to move, enabling the protective plate 39 to rotate around the support frame 34. The tilt angle of the protective plate 39 can be flexibly adjusted, so that the angle of the protective plate 39 can be quickly adjusted according to the specific needs of the deep foundation pit construction and the actual terrain on site, effectively covering the edge of the foundation pit with different heights and slopes, so that the left side of the protective plate 39 contacts the slope, thus protecting the slope.

[0037] The system is equipped with two sets of symmetrically distributed first connecting frame 36, telescopic shaft 37, second connecting frame 38, protective plate 39 and support frame 34, which can protect the symmetrical slopes on both sides of the foundation pit at the same time, and can effectively resist the lateral pressure, soil collapse impact and other phenomena that may occur during the foundation pit construction process.

[0038] When the protection is completed, the counterweight 43 can be installed by sliding the mounting block 42 into the fixed base 41. At the same time, the limiting shaft 45 is inserted into the fixed base 41 and the mounting block 42. During the insertion process, the fixing ring 46 is rotated so that the fixing ring 46 is threaded into the fixed base 41, thereby ensuring the stability of the limiting shaft 45. This allows the counterweight 43 to be installed and removed simultaneously. In the deep foundation pit construction environment, due to complex geological conditions, there may be groundwater flow, disturbance of the surrounding soil, etc., which can easily generate lateral thrust on the protective plate 39. When the counterweight 43 is added to the protective plate 39, its ability to resist these external forces is greatly enhanced, making it less likely to overturn or slide, effectively maintaining the stability of the protective structure, and ensuring the stability of the base 2 and the fixed frame 31 during use.
