Description

Technical Field

[0001] The utility model relates to a trench supporting device, in particular to a pipeline trench supporting unit. Background Art

[0002] With the rapid development of urban infrastructure construction, pipeline trench construction has become an indispensable part of municipal engineering. In the process of laying underground pipelines such as rainwater pipes, sewage pipes, power cables, etc., the excavation of pipeline trenches is a necessary construction link. However, after the trench is excavated, its side walls are often prone to collapse due to factors such as soil pressure and groundwater action, which not only threatens the safety of construction workers, but also causes damage to the surrounding environment and existing facilities. Therefore, trench support is an important measure to ensure construction safety and ensure the smooth progress of the project. Its technical level and construction quality directly affect the quality and progress of the entire project. Although traditional trench support methods such as steel sheet pile support can play a supporting role to a certain extent, there are problems such as large earth excavation and inconvenient disassembly. Utility Model Content

[0003] The utility model aims to provide a pipeline trench support unit to solve the problems of large earthwork excavation volume and inconvenient disassembly of the existing trench support.

[0004] The utility model is implemented as follows: a pipeline trench support unit, whose structure includes two relatively arranged guard plates and a supporting mechanism arranged between the two guard plates, the two guard plates are vertically and spaced apart, a ground anchor is arranged at the lower end of the guard plate, a fixing mechanism is arranged on the inner side of the guard plate, the fixing mechanism includes a rod sleeve arranged on the inner side of the guard plate and a fixing rod inserted in the rod sleeve, the lower end of the fixing rod is a tapered end, and a limiting rod is arranged on the upper part of the fixing rod.

[0005] Furthermore, the guard plate includes an outer vertical plate and a frame arranged on the inner side of the vertical plate, the fixing mechanism is arranged on the frame, the supporting mechanism is arranged on the vertical plate, and the ground anchor is vertically arranged at the lower end of the frame.

[0006] Furthermore, there are two supporting mechanisms, which are symmetrically arranged on the upper part of the guard plate.

[0007] Furthermore, the support mechanism includes two sleeves, a screw rod and two nuts arranged on the screw rod; the two sleeves are arranged on the two vertical plates opposite to each other, and the two ends of the screw rod are respectively inserted into one of the sleeves.

[0008] Furthermore, a ladder is provided on the inner side of the frame.

[0009] Furthermore, a hanging ring is provided at the upper end of the frame.

[0010] Furthermore, corresponding rod sleeves are provided on the upper and lower parts of the guard plate so that the fixing rod can remain vertical when inserted into the soil.

[0011] The utility model uses a fixing mechanism and a supporting mechanism to effectively resist external forces and pressures, increase the slope of the foundation pit slope protection, reduce the amount of earth excavation, and thus save construction costs. This economical and efficient construction method helps to reduce the overall cost of the project. The support unit provides a stable and safe operating space for workers during pipeline trench construction, effectively isolates the construction area from other potential dangerous areas, and ensures the safety of workers. The utility model allows for rapid installation and removal through modular support units, significantly reduces construction time and labor requirements, and further reduces project costs. The utility model sets a ground anchor at the lower end to avoid setting a support mechanism at the bottom of the guard plate, making it easier for the pipeline to pass through the lower space of the guard plate. The durability and detachability of the utility model allow it to be disassembled on site and reused at other construction sites, thereby improving the utilization rate and economy of materials. The use of lifting rings simplifies the handling and transfer process of the guard plate, and reduces the safety risks and labor intensity caused by manual handling.

[0015] like Figure 1 As shown, the utility model includes two oppositely arranged guard plates and a supporting mechanism arranged between the two guard plates. The two guard plates are arranged vertically and at intervals. The space at the lower part between the guard plates forms a channel for the passage of the pipeline. A fixing mechanism is arranged on the inner side of each guard plate, and a plurality of ground anchors 3 are arranged at the lower end of each guard plate. The ground anchors 3 are used to be inserted into the soil to fix the skeleton. The number and length of the ground anchors 3 can be reasonably selected according to the size of the guard plates and the soil quality to ensure the stability and safety of the entire structure.

[0016] The fixing mechanism includes a sleeve rod 4 vertically arranged on the inner side of the guard plate and a fixing rod 5 inserted in the rod sleeve 4. The lower end of the fixing rod 5 is a tapered end, which facilitates the insertion of the fixing rod into the soil to achieve a firm fixation. A limit rod 6 is arranged on the upper part of the fixing rod 5. The limit rod 6 is a short rod perpendicular to the fixing rod 5. The limit rod 6 is used to limit the depth of the fixing rod 5 inserted into the soil. When the fixing rod 5 is inserted to a predetermined depth, the limit rod 6 will contact the upper rod sleeve 4, thereby preventing the fixing rod 5 from being further inserted. In addition, when the support unit is removed, the limit rod 6 facilitates the removal of the fixing rod 5 from the soil. Corresponding rod sleeves 4 are arranged on the upper and lower parts of the guard plate to ensure that the fixing rod 5 can maintain a vertical direction when inserted into the soil, so as to better resist the horizontal and vertical forces. The inner diameter of the rod sleeve 4 should be slightly larger than the outer diameter of the fixing rod 5 to facilitate smooth insertion and removal. The fixing rod 5 is made of Φ20-22 round steel. Each guard plate is provided with a plurality of fixing mechanisms to ensure the stability of the guard plate.

[0017] The guard plate includes an outer vertical plate 1 and a frame 2 arranged inside the vertical plate 1. The fixing mechanism is arranged on the frame 2, the supporting mechanism is arranged on the vertical plate 1, and the ground anchor 3 is arranged vertically at the lower end of the frame 2. The frame 2 provides additional support and strength for the entire structure. The frame 2 is closely combined with the vertical plate to form a solid frame so that the guard plate can better withstand external forces and pressures. The frame 2 in this embodiment adopts 100 100 The 3.5 square tubes are welded with a spacing of 1000mm. The welds are fully welded and firmly welded. A ground anchor 3 made of Φ20 round steel with a length of 100mm is provided at the lower part of the frame.

[0018] The supporting mechanism includes two sleeves 7, a screw rod 8 and two nuts 9 arranged on the screw rod 8. The two sleeves 7 are arranged on the two vertical plates 1 opposite to each other. The two ends of the screw rod 8 are respectively inserted into a sleeve 7. The nut 9 is used to clamp on the outer end of the sleeve 7 to prevent the guard plate from tilting inward. The size of the nut 9 is larger than the size of the sleeve 6. By adjusting the distance between the two nuts 9, the two vertical plates 1 can be kept vertical. There are two groups of supporting mechanisms, which are symmetrically arranged on the upper part of the guard plate, and the balanced distribution of force is achieved in the structure, thereby improving the stability and bearing capacity of the whole system. The supporting mechanism can also be a beam, a bracket, a pull rod or a fastener. These devices can also provide necessary support and fixation on the upper part of the guard plate to ensure the stability and bearing capacity of the overall structure.

[0019] like Figure 2As shown, a ladder 10 is also provided on the inner side of the frame to ensure that workers can safely and conveniently enter and exit the working area in narrow or deep trenches. The entire pipeline trench support system is composed of a plurality of support units arranged adjacent to each other in sequence. In the entire pipeline trench support system, support units with ladders 10 can be used at intervals, which not only optimizes the construction layout, but also reduces the occupation of trench space, improves construction efficiency and saves costs.

[0020] A lifting ring 11 is also provided on the frame 2, by which the staff can easily lift the guard plate from the groove, or lift the guard plate to a truck for transfer when necessary. This process not only greatly improves the construction efficiency, but also reduces the safety risks caused by manual handling.

[0021] During installation, place the guard plate at the predetermined position in the pipeline trench, and then use a sledgehammer or excavator to firmly insert the anchor 3 into the soil. The two guard plates are placed vertically opposite to each other so that the space between them forms a channel. The width of the channel should be greater than the diameter of the pipeline. Then insert the fixing rod 5 into the rod sleeve 4, and use the tapered end of the lower part of the fixing rod 5 to insert it into the soil until the limit rod 6 contacts the rod sleeve 4. Then insert the two ends of the screw rod 8 into the two sleeves 7 respectively, and adjust the position of the nut 9 to support the two guard plates, that is, after the installation of one support unit is completed, the support units are installed in sequence along the length direction of the pipeline trench. After the pipeline is installed, it can be removed in the opposite order to that during installation.
