Description

Technical Field

[0001] The utility model relates to the technical field of jacking pipes, in particular to a jacking pipe inlet and outlet hole reinforcement device. Background Art

[0002] Pipe jacking is a method of underground tunnel construction. Pipe jacking is a relatively simple construction method suitable for tunnels of shorter distances and smaller diameters. Its principle is to gradually advance the tunnel by excavating the tunnel head and pushing the earth out from the end of the tunnel. This method is suitable for situations where the soil is relatively stable and no special support measures are required. In pipe jacking construction, concrete or reinforced concrete lining is installed at the rear to support the tunnel structure. Pipe jacking is usually used in urban underground transportation tunnels, water conservancy projects, drainage pipes, etc. Compared with the traditional open-cut method, this construction method can reduce interference with surface traffic and urban life, so it is widely used in urban construction.

[0003] However, traditional hole reinforcement devices usually use concrete to prevent collapse, and a lot of time is needed to build and dismantle the concrete before and after construction. Concrete is a heavy material, and using too much concrete to reinforce the structure will increase the weight of the structure, leading to the risk of ground settlement or structural deformation. In underground environments, concrete is easily affected by temperature changes and groundwater, and may crack or deform, which is time-consuming and labor-intensive, reduces work efficiency and affects the reinforcement effect.
