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 in particular, relates to a special steel integrated inner support construction method for a pipe rack. The construction method comprises the following steps: a steel integrated inner support is prefabricated; a horizontal gap of the inner support is adjusted by using a horizontal support screw; the inner support with the horizontalsupport screw is lifted to an appointed position of the pipe rack for placement; the horizontal support screw is adjusted to enable a steel template on the outer side of the inner support to be tightly bonded with a horizontal construction gap lower wall and to be fixed by a steel pin; a vertical support screw is mounted at the bottom of the inner support; the inner support is supported to a concrete driving line; the vertical support screw distributed at the bottom is adjusted; a lifting hook on the inner support is dismounted; a thin steel plate is paved; a wall and top plate concrete are cast; and after construction is finished, the horizontal support screw and the vertical support screw are dismounted, and the lifting hook is used for dragging the inner support to a next section of a base plate for lifting out. The construction method can effectively improve the construction quality, reduce the construction cost, shorten the construction period and prevent such problems as mold expansion caused by pulp leakage in horizontal construction gaps, and is simple in construction and convenient to disassemble.
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...
