Pile sinking device for precast pile construction

Abstract

The invention discloses a pile sinking device for precast pile construction, which comprises three vertical piles arranged in an equilateral triangle, each pile is provided with a vertical indicator, the upper ends of the three piles are provided with a common pile frame, the center of the pile frame is provided with a steel wire rope in a penetrating manner, the center of the lower end face of the pile frame is provided with a guide sleeve for the steel wire rope, and one side of each pile is provided with a support. The upper end of the steel wire rope is wound on the outer side of the upper portion of the pulley and then is connected to the winch in a winding mode, the lower end of the steel wire rope is connected with a pile hammer in a hanging mode, hollow guide rails with the inner ends facing the center lines of the three piles are arranged on the inner sides of the piles, and a plurality of evenly-parallel position lines are arranged on the outer side faces of the hollow guide rails in an up-down mode. The hollow guide rail is provided with a plurality of horizontal telescopic rods which can move up and down in parallel along the hollow guide rail, and the inner ends of the horizontal telescopic rods face the center line of the three piles. The inner ends of the horizontal telescopic rods are provided with clamping cambered surfaces. The device has the advantages of being simple in structure and convenient to use, and the precast pile can be assisted to vertically and rapidly sink into the ground.

Description

technical field [0001] The invention belongs to the technical field of equipment for sinking prefabricated piles into building foundations, and in particular relates to a pile sinking device for prefabricated pile construction. Background technique [0002] The prefabricated pile is sunk into the building foundation by the hammering method, which has the advantages of simple process and fast effect. Design requirements. [0003] However, most of the existing pile sinking devices lack a guiding mechanism for the sinking direction of the prefabricated piles, which cannot ensure the rapid and vertical sinking of the prefabricated piles into the ground. In order to solve the above problems, it is necessary to develop a pile sinking device for prefabricated pile construction. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a pile driving device for prefabricated pile construction with simpl...
