Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the punching device for rectangular slide piles comprises a support frame, a lifting hammer 3, a winch 4 and a steel rope 41, wherein the winch 4 and the steel rope 41 are positioned on the support frame and can drive the lifting hammer 3 to lift, the support frame comprises a truss 1 and an inclined strut 2, the bottom of the truss 1 is fixedly connected with an underground foundation through a supporting leg 15, the inclined strut 2 is arranged at the end part of the truss 1, the winch 4 is arranged at the top of the truss 1, the steel rope 41 of the winch 4 bypasses a pulley 42 at the hanging end of the inclined strut 2 and is then connected with the lifting hammer 3, the cross section of the lifting hammer 3 is of a rectangular structure, a plurality of lifting lugs are uniformly arranged at the top of the lifting hammer 3 and are connected with the steel rope 41 through auxiliary ropes 43, and a plurality of conical teeth 31 are uniformly distributed at the bottom of the lifting hammer 3.

The support frame mainly plays the effect of fixed whole device and balanced sledge hammer 3, consequently truss 1 needs to have sufficient weight and the stability of installation, and accessible increases truss 1 length and realizes, and truss 1 passes through the bolt with the underground foundation and is connected, and the underground foundation can be pre-buried rag bolt. The inclined strut 2 is used for supporting the lifting hammer 3 outside the truss 1, so that interference with the truss 1 in the lifting process is avoided. The hanging hammer 3 can be made of cast iron, weight is increased, the conical teeth 31 can be in a conical structure or a triangular plate structure, preferably a conical structure, and the hanging hammer 3 can be detachably mounted by bolts so as to be replaced after being worn and damaged.

The application process of the utility model is as follows: firstly, the construction locking is carried out similarly to the traditional mode, the locking construction has the main functions of stabilizing the hole wall to prevent hole collapse, isolating surface water, protecting the hole opening ground, fixing the pile hole position and the like, then equipment is installed, the lifting hammer 3 is aligned with the anti-slide pile hole, finally, the lifting hammer 3 is repeatedly lifted by the winch 4 to carry out punching operation, after a period of impact, the lifting hammer 3 is lifted, mud is filled into the hole, the mud is pumped out, slag stone generated by the impact is discharged, and the operation is carried out repeatedly until the punching reaches the design elevation, and the anti-slide pile punching construction is completed.

The truss 1 has a concrete structure that the truss 1 comprises two bottom cross beams 11 and two top cross beams 12 which are arranged along the horizontal direction, a plurality of support vertical rods 13 and diagonal braces 14 which are connected between the bottom cross beams 11 and the top cross beams 12, the winch 4 is fixed on the top cross beams 12 through a frame 44, and the supporting legs 15 are arranged on the bottom cross beams 11.
