Embodiment Construction
[0020] In order to further describe the construction method of a special steel integrated internal support for pipe gallery of the present invention, it will be further explained below in conjunction with the accompanying drawings.
[0021] Figure 1-2 Middle: A construction method of steel integrated internal support for pipe gallery, including the following steps:
[0022] Step 1. Construction preparation, prefabrication and processing of steel integrated inner support 1;
[0023] Step 2. Prefabricate and process the steel integrated inner support 1, which can adjust the horizontal distance, and use the horizontal support wire 2 to adjust the horizontal distance of the inner support. At this stage, the adjusted horizontal distance must be smaller than the net width of the pipe gallery;
[0024] Step 3. Hoist the inner support 1 equipped with horizontal support wire 2 to the designated position of the pipe gallery and not completely put it down, so that the inner support 1 i...

The invention belongs to the field of building construction, and specifically relates to a construction method for a special steel integrated inner support for a pipe gallery, comprising the following steps: prefabricating and processing a steel integrated inner support; using a horizontal support wire to adjust the horizontal spacing of the inner support; The inner support of the support wire is hoisted to the designated position of the pipe gallery and is not completely put down; adjust the horizontal support wire to make the outer steel formwork of the inner support closely fit with the lower wall of the horizontal construction joint, and fix it with steel pins; install the vertical support at the bottom of the inner support Support wire, lift the inner support to the concrete line and level the vertical support wire distributed at the bottom; remove the hook on the inner support and lay thin steel plate; pour concrete on the wall and roof; after the construction is completed, remove the horizontal support wire And the vertical support wire, use the hook to drag the inner support to the next section of the bottom plate and then lift it out. The invention can effectively improve the construction quality, reduce the construction cost, shorten the construction period and avoid the problems of grout leakage and mold expansion at the horizontal construction joints, and the construction is simple and convenient for dismantling.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for a special steel integrated inner support for a pipe gallery. Background technique [0002] Underground pipe gallery is the hot spot of urban infrastructure construction in my country in recent years. The cables and pipelines that were originally laid separately are gathered together and placed in the newly built underground pipe gallery, which can make the city bid farewell to "spider webs in the sky", The "road zipper" no longer needs to be "opened" frequently, and at the same time it can save land, which can be called an "artifact of storage". At present, as many cities gradually realize the importance of underground pipe corridors, more and more pipe corridor projects are under construction and will be built. In the past two years, the construction of comprehensive utility corridors in my country has exceeded 2,000 kilometers each year...
