Description

Technical Field

[0001] The invention relates to the technical field of municipal pipeline engineering, and in particular to a recyclable vertical groove corrugated steel plate support structure and a support system using the same. Background Art

[0002] In some municipal pipeline projects, it is necessary to excavate urban roads for laying pipelines or updating pipelines. To ensure the safety of surrounding roads, it is necessary to support and protect the excavated trenches. Since municipal pipeline projects on urban roads often have long construction periods and there are densely intersecting pipelines under the roads, conventional support forms often have certain limitations when used in urban areas.

[0003] At present, the most commonly used trench support methods are soil nail wall and steel sheet pile. Soil nail wall support requires slope reduction along the entire length. After slope reduction, the excavation surface is large, and the area occupied by the road is too large. The construction machinery and materials used in the construction of soil nail walls also have a great impact on the surrounding environment. Steel sheet pile support also has great limitations in urban areas. For example, there is a lot of noise when driving in and out steel sheet piles, and it causes great vibration to the surrounding strata. If there are many intersecting pipelines, there is a risk of damaging the intersecting pipelines. The existing back-mounted steel plate support structure requires the steel plate to be pressed after the trench is completed. The support method has a slight lag in support time and has high requirements for the flatness of the trench wall.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The object of the present invention is to provide a recyclable vertical groove corrugated steel plate support structure and a support system using the same, so as to solve the technical problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a recyclable vertical groove corrugated steel plate support structure, comprising: a first corrugated steel plate and a second corrugated steel plate, wherein the first corrugated steel plate and the second corrugated steel plate are detachably connected via a plurality of support rods;

[0007] The plurality of support rods are symmetrically arranged along the length direction and the height direction of the first corrugated steel plate and the second corrugated steel plate.

[0008] In an optional embodiment, the first corrugated steel plate and the second corrugated steel plate are connected with a second connecting member along their length direction, and the length of the second connecting member is not greater than the length of the first corrugated steel plate and the second corrugated steel plate.

[0009] In an optional embodiment, the first connecting member and the second connecting member are connected by bolts; the first connecting member and the second connecting member are respectively provided with an oblong hole for the bolt to pass through.

[0010] In an optional embodiment, the second connecting member is two L-shaped connecting plates spliced ​​together or one L-shaped connecting plate; the first connecting member is a T-shaped connecting plate or an L-shaped connecting plate.

[0011] In an optional embodiment, the first connecting member and the support rod are welded; the first connecting member and the second connecting member are welded or bolted; the second connecting member and the first corrugated steel plate and the second corrugated steel plate are welded or bolted.

[0012] In an optional embodiment, the support rod is a fixed-length support rod or a threaded and adjustable-length support rod.

[0013] In an optional embodiment, the axis of the support rod passes through the first corrugated steel plate, the second corrugated steel plate and the corrugated portion at the connection therebetween, and the axis of the support rod is located in the plane where the symmetry plane of the corrugated portion is located.

[0014] In an optional embodiment, a force transmission plate is provided in the corrugated portion, and the force transmission plate is in contact with the corrugated portion.

[0015] On the other hand, the present invention further provides a support system, comprising the support structure as described above, including: the support structure is divided into multiple groups, and adjacent support structures are overlapped in the length direction through adjacent first corrugated steel plates and adjacent second corrugated steel plates.

[0016] In an optional embodiment, adjacent supporting mechanisms are overlapped in the height direction by adjacent first corrugated steel plates and adjacent second corrugated steel plates.

[0017] The beneficial effects of the present invention are:

[0018] (1) The present invention adopts corrugated steel plates that are dug and sunk in vertical trenches for trench support. Before construction, the corrugated steel is first assembled into a whole using struts, and then the road structure layer above the trench is removed and cleared until the soil is exposed. The corrugated steel box is hoisted into the trench as a whole and sunk as it is dug until the designed elevation is reached. The soil can be supported to the greatest extent during the excavation process, which is safe and reliable and has little impact on the surrounding environment.

[0019] (2) The corrugated steel plate in the present invention can be disassembled and reused after the support is completed, and the support structure in the present invention has a fast construction speed, no noise during the construction process, and the impact of the construction process on the surrounding environment can be reduced to a minimum, which is an environmentally friendly construction measure. It is particularly important to point out that the axis of the support rod passes through the first corrugated steel plate, the second corrugated steel plate and the corrugated part at the connection between them, and the axis of the support rod is located in the plane where the symmetry plane of the corrugated part is located. A force transmission plate is arranged in the corrugated part to ensure the stability of the corrugated steel plate structure and improve the support effect.

[0020] (3) In the present invention, the first connecting member and the second connecting member are connected by bolts, and the first connecting member and the second connecting member are respectively provided with an oblong hole for the bolt to pass through. The oblong hole allows the two connecting members to move relative to each other, so that the second connecting member can press against the first connecting member toward the top of the support rod. Most of the supporting force of the support rod is borne by the two connecting members, avoiding excessive force on the bolts. In addition, the corrugated steel plate in the present invention has a large plane rigidity and is light in weight. It is a prefabricated product, which can greatly save engineering costs.
