The utility model solves the technical scheme that its technical problem adopts:
A device for the pre-buried assembled steel case of diaphragm wall hole to be provided, is characterized in that, includes a reinforcing cage that diaphragm wall is carried out to pouring construction; Described reinforcing cage is rectangle body of wall shape, in the middle of reinforcing cage, in the position that needs reserved opening, the steel case of a cuboid is installed; Described steel case is embedded in reinforcing cage, and front and rear surfaces exposes, and steel case is put together side by side by the little steel case of multiple rectangles level, and the surface size of steel case is greater than the size 5-10mm of reserved opening, the thick 10-20mm of Thickness Ratio reinforcing cage of steel case.
In such scheme, described steel case includes the steel case skeleton that latticed reinforcing bar forms, and the little steel case wherein forming is the cuboid straight down, and the horizontal section of its each little steel case is square.
In such scheme, described steel case is welded in reinforcing cage, and is enclosed construction, and the top of a little steel case at steel case middle part is open architecture, for walking of concrete cast conduit.
In such scheme, on the outer surface plate up and down of described each little steel case, all symmetry is drilled with several duck eyes, ensures that mud can enter steel case, reduces the buoyancy of steel case, is convenient to reinforcing cage and sinks down into design elevation.
In such scheme, described steel case skeleton is formed by multiple cross bars and montant overlap joint, and montant adopts angle steel to make, and cross bar is reinforcing bar, and cross bar fastens on montant by U-shaped.
While adopting said apparatus to construct, adopt following steps:
Accurate Calculation, and find the position of reserved opening on diaphragm wall;
Press reserved opening size and make steel case, the thickness of steel case should be thicker than reinforcing cage, the every side in both sides is higher than reinforcing cage, ensure that steel case has topping, on the outer surface plate up and down of each little steel case, bore some duck eyes simultaneously, ensure that mud can enter steel case, reduce the buoyancy of steel case, be convenient to reinforcing cage and sink down into design elevation;
Then carry out the making of reinforcing cage, make when reinforcing cage the position reserved opening of pre-buried steel case;
The steel case of making is inlaid into reinforcing cage reserved opening place;
Then carry out consolidation process, steel case is welded on reinforcing cage, bond pad locations can only be on steel case side plate;
The reinforcing cage of pre-buried good steel case, by designing requirement position and the heavy groove inlet section of absolute altitude, is then penetrated to concrete cast conduit and carries out fluid concrete;
After pit earthwork completes, then take the U-shaped card on steel case apart, i.e. dismountable steel case, reserved opening is plastic.
The beneficial effect that the utility model produces is:
It is convenient that the utility model is made, installed and removes, and material can repeatedly use, and construction dimensional standard, has met workmanship, and labour intensity is low, and cost is low.
