Problems solved by technology

[0004] During the overall pouring process of the power ditch, the traditional roof formwork support method is: build an earth girder on the bottom plate of the power ditch, the earth girder is about 10-20cm higher than the bottom plate of the power ditch, and then support the steel pipes used for support on the soil On the girder, after the bottom slab of the electric power ditch is poured, a steel bar head of about 10 to 20 cm is left on the bottom slab. The support method has the following disadvantages: 1. The concrete needs to be removed before cutting the steel bars, which wastes manpower and is not beautiful; 2. The exposed steel bars cause waste of materials and are unsafe

Embodiment Construction

[0011] The following are embodiments of the present invention:

[0012] Construction of side wall and roof formwork support

[0013] 1 side wall and roof formwork installation

[0014] The bottom plate, side wall and roof formwork of the cable trench are generally made of 12mm thick bamboo plywood, the side wall and roof brackets are made of full-height steel pipe brackets, and the top brackets are screw top brackets for easy height adjustment. Fix the wall formwork by pulling bolts and using scaffolding.

[0015] (1) template design

[0016] The side wall and roof formwork is made of bamboo plywood, 12mm thick, with 5×8cm square timber with a spacing of 60cm back ribs, assembled horizontally, Φ48 steel pipe support system, combined with "butterfly"-shaped buckles, pull screws and turnbuckle screws. Because the maximum lateral pressure is at the lower part during construction, it is planned to adopt @600×350mm two-way arrangement for pull screws below 1.2m of the wall, and ...

Abstract

The invention relates to the field of electric construction, in particular to a support method of a top plate template in an electric ditch whole pouring process. The support method comprises the following steps: a soil beam is embedded in a concrete baseplate of a cable ditch; the total height of the soil beam is lower than the upper plane of the concrete baseplate by 2-3 cm; a transverse rib of the soil beam is higher than the bottom surface of the concrete baseplate by 15 cm; then, the upper end of the soil beam is coated with a PVC pipe; the bottom end of the PVC pipe is joined on the transverse rib; a support steel pipe is inserted in the PVC pipe, and coats the soil beam; after the concrete baseplate is poured, the support steel pipe and the PVC pipe are pulled away; and a hole left by the PVC pipe is floated by expansion waterproof mortar. The support method has the following beneficial effects: the support method can save the reinforcement cutting process, saves the cost, is safe and beautiful, guarantees whole pouring of the baseplate with a thickness of 15 cm on the soil beam, and can guarantee water resistance.
