Embodiment Construction
[0025] Such as figure 1 , figure 2 as well as image 3 Shown, construction method of the present invention comprises the following steps:
[0026] a. Binding the upper and lower steel bars of the bottom plate of the comprehensive pipe gallery. The upper steel bars include the upper distribution bars 2 at a certain angle to the horizontal plane and the upper horizontal bars 3 arranged along the upper distribution bars 2 and parallel to the horizontal plane. The upper horizontal bars 3 and the upper distribution bars Ribs 2 are perpendicular to each other. There are several upper distribution ribs 2 side by side, the upper horizontal ribs 3 are distributed along the upper distribution ribs 2, and the upper horizontal ribs 3 are bound on the upper distribution ribs 2 to form a grid surface with a certain angle to the horizontal ground.
[0027] b. Determine the installation position of the short steel bar 6, and determine the position of the full scaffolding pole 7 along the ...

The invention relates to a construction method for a scaffolding support system of a comprehensive pipe gallery with a slope, comprising the following steps: a. Binding steel bars on the bottom plate of the comprehensive pipe gallery, the upper steel bars include upper distribution bars at a certain angle to the horizontal plane and upper horizontal bars parallel to the horizontal plane ; b. Determine the installation position of the short steel bar; c. Pull a standard line parallel to the upper horizontal bar right above each upper horizontal bar, make the short steel bar perpendicular to the standard line and bind the short steel bar to the upper horizontal bar ; d. Check and accept the installed short steel bars; e. Pouring the bottom slab concrete; f. After the concrete is solidified, insert the vertical poles on the short steel bars exposed on the bottom slab to support the scaffolding support system; g. After the scaffolding is used, Remove the scaffolding, use a cutting machine to cut off the part of the short steel bar exposed to the concrete surface, and use cement mortar to smooth the surface of the base plate. The supporting system of the full house scaffold built by the construction method of the invention has good stability, is safe and reliable, and can withstand relatively large forces.
Description
technical field [0001] The invention relates to a scaffolding construction method, in particular to a construction method for a scaffolding support system of a comprehensive pipe gallery with a slope. Background technique [0002] The comprehensive pipe corridor is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports and hoisting ports And monitoring system, the implementation of unified planning, unified design, unified construction and management, is an important infrastructure and lifeline to ensure the operation of the city. [0003] However, the comprehensive pipe gallery often encounters slopes during the specific construction process. When the slope ratio is less than 1:0.4, since the vertical poles of the scaffolding support system are basically placed on th...
