Step 2: according to the planning of piping lane, carrying out line setting on the ground, and the soil of piping lane foundation pit is carried out using excavator Side excavates, and carries out slope processing to foundation pit two sidewalls and forms side slope, and the earthwork is deposited on the ground of piping lane foundation pit two sides, repairs Then the bottom surface of homogeneous tube corridor foundation pit forms foundation pit bed course in piping lane foundation pit bottom surface upper concrete;

Step 3: after foundation pit bed course reaches design strength requirement, steel construction external mold is marked in the foundation pit bed course of construction section Then steel construction external mold is hung on foundation pit bed course by position with crane, in the steel construction external mold upper end etc. of steel construction internal model two sides Several crossbeams are arranged in distance, and the both ends of crossbeam and the upper end of two sides steel construction external mold are fixed;

Step 4: binding piping lane bottom plate and piping lane side plate skeleton reinforcing steel bar install the inner support of piping lane bottom plate, are poured concrete Piping lane bottom plate is formed, after piping lane bottom plate reaches design strength requirement, removes inner support;

Steel construction internal model: being hung on piping lane bottom plate by step 5 with crane, binds the skeleton reinforcing steel bar of piping lane top plate, then will The earthwork being deposited on the ground of piping lane foundation pit two sides is filled between steel construction external mold and side slope;

Step 6: reinforcing bar concealment acceptance and mold plate verticality, piece are checked and accepted, and after acceptance(check), casting concrete forms pipe After corridor side plate and piping lane top plate, piping lane side plate and piping lane top plate reach design strength requirement, by it of steel construction external mold and side slope Between the earthwork dig out;

Step 7: the adjustable screw thread of steel construction internal model is adjusted, until steel construction internal model height, width are respectively less than in piping lane storehouse Dead size is translated out steel construction internal model out of piping lane storehouse to remove steel construction external mold with hydraulic pulley;

Step 8: the surface of steel construction external mold and steel construction internal model being cleared up, is polished and brush interleaving agent, then with hanging Vehicle is hoisted to next construction section.

Preferably, the length of the steel construction external mold is 5-7m, width 0.7-0.8m;The outer wall of the steel construction external mold For steel plate, the inside of the steel construction external mold is steel truss structure.

Preferably, the length of the steel construction internal model is 5-7m;The outer wall of the steel construction internal model is steel plate, the steel knot The inside of structure internal model is steel truss structure.

The beneficial effects of the present invention are: steelframe combined steel template intensity is high, indeformable, concrete Forming Quality is good;Using machine Tool is turned into industry, reduces the demolition, installation time of formwork bracing system, reduces labor intensity, accelerate construction speed;Do not make With split bolt, construction consumptive material is saved, while having prevented the possibility of split bolt construction node leak;Piping lane top plate and piping lane side The molding of plate one-time-concreting, improves concrete impression quality, while reducing horizontal construction joint, waterproof performance is further promoted.

Specific embodiment
