Description

Technical Field

[0001] The utility model belongs to the technical field of municipal construction, and in particular relates to a temporary supporting device for rapid construction of municipal pipelines. Background Art

[0002] In the construction of municipal pipeline projects, trench support is not carried out in time after trench excavation. When the external environment changes, trench collapse and casualties often occur. The existing trench protection devices generally require on-site buried Larsen steel sheet piles, which has complicated procedures and needs to be disassembled after use. After the construction area is changed, the support device needs to be constructed again, and free movement cannot be achieved. Therefore, it is necessary to design a temporary support device for rapid construction of municipal pipelines to solve the above problems. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a temporary support device for rapid construction of municipal pipelines, which solves the problems of poor mobility and complicated assembly and disassembly procedures of the trench support device in the prior art, and has the characteristics of being easy to construct, movable, and able to adjust its position at any time according to the construction area.

[0004] In order to realize the above-mentioned design, the technical solution adopted by the utility model is:

[0005] A temporary support device for rapid construction of a municipal pipeline comprises two sets of retaining mechanisms, between which multiple sets of supporting mechanisms are connected; the retaining mechanisms comprise a supporting ring of an annular structure, which contacts and cooperates with the inner wall of a groove.

[0006] Preferably, a steel mesh is connected inside the support ring.

[0007] Preferably, the supporting mechanism comprises an internally threaded sleeve, and the inner walls at both ends of the internally threaded sleeve are provided with reverse internal threads.

[0008] Preferably, both ends of the internally threaded sleeve are respectively threadedly connected to independent screw rods.

[0009] Preferably, both ends of the screw rod are rotatably connected to the support ring via bearings.

[0010] Furthermore, multiple groups of support mechanisms may be provided.

[0011] The beneficial effects of the above-mentioned temporary support device for rapid construction of municipal pipelines are as follows:

[0012] The support ring of the device adopts steel mesh to reduce the overall weight of the device; the width can be adjusted through the support mechanism to adapt to trenches of different widths; the circular support ring is convenient for workers to roll and push; the device can be placed according to soil conditions and trench support positions to effectively protect, resist initial small-area collapse, and quickly evacuate to ensure the safety of workers; the device can be rolled and moved as the construction progresses to achieve rapid support. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The reference numerals in the figure are: retaining mechanism 1, supporting ring 11, steel mesh 12, supporting mechanism 2, internal threaded sleeve 21, screw rod 22. DETAILED DESCRIPTION

[0015] like Figure 1 A temporary support device for rapid construction of a municipal pipeline includes two sets of retaining mechanisms 1, and multiple sets of supporting mechanisms 2 are connected between the two sets of retaining mechanisms 1; the retaining mechanism 1 includes a supporting ring 11 of an annular structure, and the supporting ring 11 is in contact with the inner wall of the groove.

[0016] Preferably, a steel mesh 12 is connected inside the support ring 11 .

[0017] Preferably, the supporting mechanism 2 comprises an internally threaded sleeve 21 , and the inner walls at both ends of the internally threaded sleeve 21 are provided with reverse internal threads.

[0018] Preferably, both ends of the internal threaded sleeve 21 are respectively threadedly connected to independent screw rods 22 .

[0019] Preferably, both ends of the screw rod 22 are rotatably connected to the support ring 11 via bearings.

[0020] Furthermore, the supporting mechanism 2 can be provided in multiple groups.

[0021] The working principle of the utility model is as follows:

[0022] When in use, the extension and retraction of the screw rods 22 at both ends are adjusted through the support mechanism 2, so that the support rings 11 on both sides are pressed against the inner wall of the groove to form support; when the construction is completed, the support mechanism 2 can be retracted slightly to release the support force on both sides, and then the device can be pushed to the next construction area to re-form support.
