Assembled steel bracePreparation for construction:
1, site preparation
(1Determine the location of steel components and the entry and exit lines of construction machinery.
(2) Clear construction roads and travel routes.
2, construction site layout
The main basic materials and facilities in the construction stage of assembled steel composite support are: steel, supporting components and accessories, stacking site; Construction machinery and tools such as digging machine, crane, air compressor, electric welding machine, etc.; On-site office and living area. According to the different construction stages, dynamically optimize the layout of the site, according to the actual situation reasonable arrangement of the process, to ensure the smooth construction.
3Technical and site construction preparation before commencement
(1Before construction, self-review and co-review shall be carried out on drawings to clarify design requirements and deformation control standards, calculate the types and quantities of required standard parts and non-standard parts, and master the construction process.
(2) To make technical disclosure of design, the requirements are as follows: the invited designers shall come to the site to make technical disclosure of design intention, deformation control, prestressed construction, emergency plan, quality control issues and key technical issues to the technical and management personnel of the construction unit, and form technical disclosure documents for future reference.
(3) Measure and release the wire
According to the design drawings and positioning coordinates, determine the main coordinate values such as the position of retaining pile, column pile, enclosing purlin and connecting parts of the foundation pit, lay out the line to the points, and set the mark pile to protect the placed position points.
(4) excavate the working face
Slotted in preparation for construction face, bottom elevation controlled in design supportBottom elevation-0.5mPosition, and width is the width of enclosing purlin+Width of slope discharge. In the joint position and the position of the brace, the Angle brace should be slotted, the width of the size of these components+Width of slope discharge.
