Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline trench support technology, specifically a trailer-type support device. Background Technology
[0002] Pipeline trench excavation typically employs ordinary steel sheet pile support. Traditional steel sheet piles require pile driving equipment or cranes, resulting in high overall transportation and storage costs, low turnover rates, short service life, and the generation of noise or vibration. Different geological and hydrological environments for pipeline trench installation necessitate varying requirements for trench excavation depth and width. Using traditional steel sheet pile support is therefore uneconomical and inappropriate; trench excavation and support methods must be tailored to local conditions. Utility Model Content
[0003] The purpose of this invention is to provide a trailer-type support device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a trailer-type support device, comprising support side plates, mounting components, supporting steel beams, and traction rings. Two support side plates are provided, and the two support side plates are arranged parallel and perpendicular to each other. A supporting steel beam connects the top two sides of the two support side plates. The supporting steel beam is fixedly connected to the surface of the support side plates via the mounting components. A first reinforcing plate is installed between the top surface of the mounting components and the surface of the support side plates. A second reinforcing plate is installed between the bottom surface of the mounting components and the surface of the support side plates. A traction ring is welded to the front of the mounting components.
[0005] Preferably, the bottom of the support side plate is provided with a cutting edge.
[0006] Preferably, a number of reinforcing ribs are evenly distributed on both sides of the support side plate.
[0007] Preferably, the supporting steel beam is fixedly connected to the mounting component by fixing bolts.
[0008] Preferably, the mounting components and supporting steel beams are made of H-beams.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model consists of two support side plates and corresponding support steel beams, making the entire support device a tow box design. The tow box design can be pulled as excavation progresses. The two support side plates have a range to ensure pipeline laying operations, thus ensuring the safety of workers during pipeline laying. The soil in front of the tow box needs to have a certain inclination angle to prevent collapse. Moreover, compared with traditional steel sheet piles, the overall transportation and storage size is smaller, saving storage and transportation costs. At the same time, the support steel beams are fixedly connected to the installation components by fixing bolts, which can be disassembled and assembled in a short time. Furthermore, the entire device does not require pile driving equipment, cranes, etc., which can save construction costs. Attached Figure Description
