Carrier pile construction equipment and carrier pile construction method

Abstract

The invention provides carrier pile construction equipment which comprises a chassis, a bracket, a support rod, an inner pipe and an outer pipe. The carrier pile construction equipment is characterized in that a hammering device, a vibrating device and a lifting device are arranged on the bracket; the hammering device comprises a pile hammer, the inner pipe and the outer pipe and is used for realizing the functions of sinking the inner pipe and the outer pipe synchronously and compacting filling materials; the vibrating device comprises a mesoporous vibratory hammer and a pair of hydraulic calipers and is used for realizing the functions of lifting out and sinking the outer pipe in a vibrating way; and the lifting device comprises a windlass, a rope and a pulley block and is used for realizing the function of moving the pile hammer and the mesoporous vibratory hammer up and down. The invention further provides a carrier pile construction method which comprises the following steps: 1) sinking the inner pipe and the outer pipe synchronously, and meanwhile vibrating the outer pipe to help to form a hole; 2) sinking the inner pipe and the outer pipe to a preset depth; 3) performing reinforcing treatment of a pile end by one of various methods; 4) repeating the operation in step 3), forming a carrier at the pile end by one of various control methods, and realizing equivalent calculation of the area Ae; and 5) constructing a pile shaft by one of various methods.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the construction of piles. Background technique [0002] The carrier pile is a pile foundation technology that has developed rapidly in recent years and has been widely used. It was first disclosed in the patent document No. ZL98101041.5. The pile type includes a composite carrier and a concrete pile body. Instead, focus on the maximum and optimal reinforcement and compaction of the soil under the pile tip, and effectively form a composite carrier through the three-strike penetration standard, so that the upper load can effectively pass through the pile and the composite carrier below the pile, It is transmitted to the better bearing layer, thereby greatly improving the bearing capacity of the pile, so it has the advantages of high bearing capacity of a single pile and economical cost. At the same time, in the patent document ZL98101331.5, a kind of construction equipment invent...

AI Technical Summary

Problems solved by technology

However, the above-mentioned construction methods and construction equipment often encounter some difficulties in construction, such as difficulty in forming holes or slow hole formation speed when encountering relatively hard soil layers, low work efficiency in the process of filling and tamping, and when encountering When the soil layer at the pile end is hard, it is difficult to carry out filling and tamping operations. Due to the limitations of construction methods and construction equipment, the pile body is short, etc., especially the construction methods and mechanical devices are relatively backward, and cannot be adjusted according to changes in geological conditions and design requirements. , so that the work efficiency is reduced and the cost is increased
