The stationary concrete batching plant foundation consists of mixing the host foundation, the cement warehouse foundation, the sandstone silo foundation, the gravel material retaining wall foundation, the concrete mixing station site foundation and the control room foundation. The construction of the concrete batching plant foundation is very important.
How to build the foundation of stationary concrete batching plant?
First, select the required base plan and site layout according to the terrain;
Then, according to the technical requirements of commercial concrete mixing plant line, find a good reference point, the size of the difference between the two basics should not be greater than 50mm, with lime to lay out the basis of the center and the size of the excavation of the base range;
When the foundation is excavated, the centerline position of the foundation is marked with steel or prong, and the position of the two embedded iron center lines on the same basis shall be on the same line, the deviation shall not be greater than 20mm;
Require the laying of reinforced concrete mesh in the foundation of the commercial concrete mixing plant, the rebar shall not be lower than the required size in the drawing, the depth and width of the excavation shall not be lower than the required size in the drawing;
Shall not arbitrarily change the size of the drawings marked, if any changes to be notified to the venue technical guidance staff, make a written proof;
According to the requirements of commercial concrete mixing plant drawings to prepare pre-embedded iron, the size of the embedded iron can not be arbitrarily changed, if necessary to change the venue must inform the technical staff to make a written proof;
Second, the basis of mining qualified concrete after pouring, the need for secondary pouring must be secondary pouring, the label can be C20-C30;
The pre-cast iron should be kept in place above the ground level ± 0.00 level and adjacent to the level of the buried iron, parallel, and shall not have a torsion angle, deviated from the center of the phenomenon, if the foundation is higher than the ground The highest aspect of the foundation is flush;
The level of the concrete batching plants must be detected by the level meter and the super leveling instrument, otherwise it will cause the foundation to be uneven and cause unnecessary loss.
