Description

Technical Field

[0001] The utility model relates to a pipeline installation slope supporting device, belonging to the technical field of slope protection. Background Art

[0002] At present, most outdoor municipal drainage installations require slope excavation of earthwork to ensure the personal safety of construction workers at the bottom of the foundation pit. The foundation pit of municipal drainage is often small and slender. Traditional municipal drainage excavation mainly uses excavators to dig and then cooperate with manual cleaning to carry out construction. After the trench is excavated and formed, it is paved with crushed stones as a cushion layer, and commercial concrete is used for pouring. Then, the steel bars are tied, the formwork is installed, the concrete is poured, and the demolding is formed to form a drainage ditch structure. In this process, the earthwork slope excavation must be carried out first, then the slope is released, and then the drainage installation is carried out, so the construction process takes a long time.

[0003] CN202022809174.6 in the prior art is a construction pit retaining structure, which is directly connected to the pit retaining baffle through the left and right protective support rods, and can be embedded in the surface of the pit retaining baffle. The left and right protective support rods can be transported together with the pit retaining baffle to reduce the trips of back and forth transportation, and can be placed around the pit, and then the left and right protective support rods are propped up for support, which is conducive to the progress of the processing project. However, this kind of retaining structure is difficult to enclose according to the foundation pits of different specifications, and the stability of the retaining mechanism placed around the pit is not high, which may cause the slope to lose stability and lead to safety accidents on site.

[0017] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0019] A pipeline installation slope support device comprises two baffles 1, a threaded push rod device is arranged between the two baffles 1, the threaded push rod device comprises a screw 2 and a threaded sleeve 3, one end of the screw 2 is fixedly connected to the wall surface of one of the baffles 1, the screw 2 is threadedly connected to the threaded sleeve 3, the other end of the threaded sleeve 3 is rotatably connected to a connecting seat 4, and the connecting seat 4 is fixedly connected to the wall surface of the other baffle 1; a baffle shed assembly is arranged on the top of the two baffles 1, and a pull ring 7 is arranged on the side walls of the two baffles 1;

[0020] At present, the outdoor official website of the construction site first carries out earth excavation and then carries out slope reduction processing at the same time. After the excavation of the pipeline foundation pit is completed, the slope support device is lifted by an excavator and placed in the foundation pit. Then, the threaded push rod device inside the adjustment device is adjusted, that is, the threaded sleeve 3 is rotated. Since the threaded sleeve 3 is rotatably connected with the connecting seat 4, the threaded sleeve 3 is rotated to make the screw 2, so that the baffle 1 is stably pressed against the walls on both sides, eliminating the process of earth slope reduction, and dragging it through the pull ring 7 on the baffle 1 to form a relatively safe working environment inside the foundation pit.

[0021] The canopy assembly includes a detachable support rod 5, which is arranged on the top of the two baffles 1. The detachable support rod 5 and the top of the two baffles 1 are connected by embedded bolts. The top of the detachable support rod 5 is slidably connected to the ceiling 6, and a slide groove 61 is arranged at the bottom of the ceiling 6. The top of the detachable support rod 5 is slidably engaged with the slide groove 61, and the ceiling 6 has a certain curvature, which can effectively block the rain from falling on the top, etc.; the sliding connection between the slide groove 61 and the detachable support rod 5 can move synchronously while the threaded top rod device is adjusted to change the distance between the two baffles 1.

[0022] Material reduction grooves 8 are provided on the walls of the two baffles 1 to save materials.

[0023] The working principle of the above-mentioned pipeline installation slope support device is as follows:

[0024] After the excavation of the pipeline foundation pit is completed, the slope support device is lifted by an excavator and placed in the foundation pit. Then, the threaded push rod device inside the adjustment device is used to make the baffle 1 stably supported on the walls on both sides, eliminating the process of earthwork slope reduction. The baffle 1 is dragged by the pull ring 7 on the baffle 1 to form a relatively safe working environment inside the foundation pit.

[0025] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
