Further, the filler of described channel-section steel inside is plank or hardboard or plastics package filler.
A kind of П type assembling sheet pile supporting and protection structure of the present utility model has the following advantages:
1, pattern foundation pit supporting structure type can be enriched, expand pattern foundation pit supporting structure range of choice, shorten the construction period, realize energy-saving and cost-reducing, promote Sustainable Construction Industry;
Brief description is carried out to the economy of Π type assembling sheet pile supporting and protection structure and rigidity:
1) economy
Π type assembling sheet pile supporting and protection structure, effectively can reduce materials'use, and factory produces in batches, can manufacturing cost be reduced, component can be realized and recycle, assembled by piecemeal, reduce single lifting lifting capacity, reduce mechanical instructions for use, utilize baffle plate to play sealing antiseepage effect simultaneously.
2) rigidity
Rigidity increases, and be exactly that second moment of area increases, material concentrates on T connector end and baffle plate, utilizes web and cement-soil acting in conjunction to improve stock utilization, realizes rigidity and increase.
2, adopt fabricated construction, convenient and quick construction, doubles as the effect of retaining soil and water;
3, pattern foundation pit supporting structure form is expanded to spatial model from the plane mode of routine, the globality of strengthening supporting structure, effectively improve the rigidity of supporting and protection structure, realize the safety and stability of base pit engineering.
