Abstract

The present invention relates to a multifunctional pile driver for building construction. It is characterized by that it includes upper pile frame and lower pile frame, said upper pile frame and lower pile frame are oppositely rotatably-connected, the lower pile frame is equipped with a running mechanism, and the upper pile frame is equipped with supporting device, in the rear end of said upper pile frame a counterweight sand box is mounted, in the front end of said upper pile frame a guideway upright post is hinged, on the guideway upright post a pile-sinking device is connected, and said pile-sinking device can be upward and downward slided on the guideway upright post; the front end of said running mechanism is equipped with a front steering apparatus; the middle portion of said lower pile frame is equipped with an auxiliary supporting device; between the upper pile frame and guideway upright post a diagonal bracing device is mounted; the pile-sinking device includes a diesel hammer, said diesel hammer is connected with said guideway upright post and can be upward and downward slided on said guideway upright post, the lower end of said diesel hamper is connected with a pipe pile; said pipe pile is a hollow circular pipe body, its upper end is equipped with an air outlet and its bottom surface is equipped with an air inlet, the lower end of said pipe pile is movable connected with a mud guand.

Description

technical field [0001] The invention relates to a building construction machine, in particular to a multifunctional pile driver. Background technique [0002] At present, when carrying out foundation piling in small and medium-sized building construction, the commonly used methods are: 1. Excavation of foundation groove pouring pile method; 2. Winch pile driver perforated pile method; 4. Vibration hammering method to drive prefabricated piles; 5. Auger drill pile driver to drill cast-in-place piles. [0003] A brief introduction to each piling method is given below: [0004] 1. Excavation foundation groove pouring pile method [0005] This method needs to lay the foundation line first, then dig to the required depth according to the line, then fill it with Sanhua soil (a mixture of lime and soil with a volume ratio of 3:7), tamp it with an electric ram, and finally pour it. [0006] 2. Winch pile driver perforated pile method [0007] The hois...

AI Technical Summary

Problems solved by technology

[0014] Among the above various piling methods, the method of excavating foundation grooves and pouring piles is labor-intensive and time-consuming; the construction speed of the hoist pile driver perforated pile method is slow and the efficiency is low; , has high requirements on the construction site, and is not suitable for construction in narrow areas or areas with many buildings. Therefore, this pile driver is not suitable for piling in small and medium-sized buildings, and the scope of application is narrow; Both structure and prefabricated piles have certain requirements, and are suitable for construction in soft soil layers, but for dense sand layers and loosely structured fine sand layers or hard soil layers, construction is difficult and easy to damage prefabricated piles , so the scope of application is narrow; the auger pile driver bored pile method and other pile driving methods can only drive a certain type of pile, and the function is single
