Described main body of cross-beam is i iron, and i iron two ends are welded with the contiguous block consistent with i iron section, and contiguous block is provided with fixing hole, and described joint angle two ends are provided with ledge, and ledge is provided with the fixing hole corresponding with contiguous block.Adopt i iron, reduce the weight of whole support system, reduce the labour of workman, i iron bearing capacity is better simultaneously, ensures the safety of active well; Adopt bolt joint angle and contiguous block to be coupled together closely by fixing hole, ensure the stable of steel frame.
Described vertical steel is divided into three parts, is upper steel pipe, middle steel pipe, lower steel pipe respectively; Middle steel pipe is comparatively thick, and upper steel pipe is inserted in the lower steel pipe of neighboring vertical steel, is provided with the through hole corresponding with lower steel pipe in the middle part of described joint angle.Lower steel pipe, through the through hole of joint angle, is inserted in the upper steel pipe of neighboring vertical steel, connects successively, forms post.
Described support system four sides are all vertically provided with gear building plate, and gear building plate is strip; Many places, described crossbeam bottom are provided with supporting steel pipe.Gear building plate can prevent soil from entering into active well; Supporting steel pipe has higher flexural strength, and fixing steel frame is on the active well borehole wall, for convenience detach.
The utility model has the advantages that:
This system can realize resistance to compression shearing resistance and the requirement of sedimentation scheduling theory, and safety factor is higher, simultaneously short construction period, and invest little, recyclable recycling, space availability ratio is high, meets growth requirement.
