For the deep foundation pit supporting steel purlin supporting scheme of a

Answer:

The steel sheet pile is inserted into the steel sheet pile: the first pile is inserted into the continuous steel sheet pile and is inserted into the design depth of the steel sheet pile supporting system of the foundation pit along the front pile buckle grooveSteel plate pile construction setting allow error: pile top elevation deviation + 100mm steel plate pile axis deviation + + 100mm steel plate pile verticality deviation 1%; should be monitored in the allowable error rangeSteel plate piles with steel sheet pile, pile deviation, making itself the error limitation of construction to ensure the actual degree of steel sheet pile curtain according to the standard width of the integer times of steel sheet pile curtain end closed up by the difficulty of adjustment phase do like profiled steel sheet pile closure or through adjusting curtain axis using standard pile to achieve closure due to the engineering precision of sheet pile wall the realization of high angle closure of the corner on both sides of the 10 sheet pile width adjustment axis to achieve closure is Department of steel sheet pile by welding of foot like fish plates for welding to avoid two adjacent pile connected with the depth of 1M and the appropriate position should be connected to the wrong place pile spacing

Construction sequenceThe pile axis positioning, U type steel sheet pile, steel sheet pile on both sides of steel purlin installed to dig to the bottom, soil structure construction, soil filling, U type steel sheet pile, the extraction of 5 operating baseline determination: Construction of foundation pit construction need to leave Longmen frame fixed axis working face to determine the position of steel sheet pile construction fixed pile position according to the order of the steel sheet pile concrete pile with marked gray line marked the plate pile driving by self vibration type steel sheet pile special mechanical plug
