Detailed Description
The invention is described in detail below with reference to the drawings and examples.
Referring to fig. 1 and 2, a deep cup mouth template of a bearing platform foundation is composed of a cup mouth wood box 1, a wood square support piece 2, a polystyrene board 3 and an adhesive tape 4. The cross section of the cup opening wooden box 1 is the size of a concrete cup opening to be poured minus the thickness of the two polyphenyl plates 3, in the embodiment, the cup opening wooden box 1 is a box body with a square cross section, the upper end of the cup opening wooden box 1 is open, the cup opening wooden box 1 is composed of four vertical plates and a bottom plate, and the vertical plates and the bottom plate are made of multilayer plates.
The inside of rim of a cup wooden box 1 installs timber side support piece 2 all around, and timber side support piece 2 comprises four vertical timber sides 2-1 and a plurality of horizontal timber sides 2-2, and horizontal timber sides 2-2 layer number is confirmed according to rim of a cup degree of depth, installs horizontal timber side 2-2 between the adjacent vertical timber sides 2-1, and the up end of four vertical timber sides 2-1 is higher than the up end of rim of a cup wooden box 1.
The outer contour surface of the cup opening wood box 1 is coated with the polyphenyl board 3, the polyphenyl board 3 is coated on the outer surfaces of the bottom board of the cup opening wood box 1 and the four vertical boards, the upper end surface of the polyphenyl board 3 is guaranteed to be consistent with the surface of a concrete cup opening, the thickness of the polyphenyl board 3 is 50 mm, the periphery of the polyphenyl board 3 is fixed through transparent adhesive tapes 4 (shown in fig. 1), and the distance between two adjacent adhesive tapes 4 is 300-500 mm. The outer surface of the polystyrene board 3 is provided with a plurality of blind holes 3-1, the cross section of the blind holes 3-1 is in an irregular shape, the blind holes 3-1 are irregularly arranged, the depth of the blind holes 3-1 is 5-10 mm, and the diameter is about 15-20 mm.
A construction method of a deep cup mouth template of a bearing platform foundation comprises the following steps:
