Construction equipment for carrier pile

Abstract

The invention provides construction equipment for a carrier pile. The construction equipment comprises a pile support which is provided with a chassis and a support and a pounding system which is provided with a protection sleeve, a pounding hammer and a main winch, wherein the pounding hammer is hung and driven by the main winch to pound a bottom in a protection sleeve; and the construction equipment is characterized in that the equipment further comprises an automatic material filling device which can fill padding quantitatively into the protection sleeve for several times, an automatic pounding control device which controls the main winch to lift the pounding hammer automatically according to a preset height for pounding the padding and an automatic three-strike penetration detection device which can automatically detect and record a penetration value of the pounding hammer after each time of falling and pounding, so that during construction of the carrier pile, presetting, monitoring and recording of construction parameters and automatic constructing are realized. The construction equipment further comprises the automatic three-strike penetration detection device, one-strike penetration generated by the pounding hammer which falls freely at a certain height and strikes on soil or padding in a foundation can be automatically detected, and multi-strike penetration can be continuously detected, and data is recorded and output.

Description

technical field [0001] The present application relates to the field of civil engineering, in particular to construction equipment for carrier piles. Background technique [0002] The carrier pile is a new type of pile that has developed rapidly and is widely used in recent years. It has the advantages of high bearing capacity, wide application range, and low cost. Its core mechanism is that the soil at a certain depth and range under the pile tip is dense. After sinking the casing to the design elevation, put fillers into the casing in batches, tamp it repeatedly with a column hammer to form a carrier, fill in concrete for tamping after reaching the three-strike penetration requirement, and finally pour concrete into piles. Therefore, the main capabilities and control points of supporting equipment used for carrier pile construction are how to quickly and conveniently realize filling, compacting, and measuring three-strike penetration. [0003] At present, the supporting eq...

AI Technical Summary

Problems solved by technology

[0003] At present, the supporting equipment used for the construction of carrier piles is all manually controlled, especially in the aspects of filling, compaction, and measurement of three-strike penetration, etc., which require the cooperation of many skilled workers. This situation not only causes construction Cost increase, low efficiency and other negative effects, and it is easy to have many adverse effects on the construction quality of the carrier pile, such as: 1. The rammer is lifted by the manual operation winch, and the falling distance of the rammer cannot be accurately controlled. In the high soil layer, if the falling distance of the rammer is too large, it is easy to cause more casings to be hammered out, which will disturb the soil and affect the quality and efficiency of pile formation; The method makes the amount of filler and the falling distance of the rammer not be matched accurately, especially when there is often too much filler, too much filler enters the casing and cannot be rammed out of the casing, causing damage to the casing, or too little filler is hammered out of the casing. Excessive length of the barrel causes disturbance of the soil, etc., and the total amount of filler cannot be accurately measured

3. The measurement of the three-strike penetration is the main control index of the carrier pile carrier. However, the manual measurement of the three-strike penetration has problems such as poor measurement accuracy, long measurement time, and inconsistent measurement states. , which has the greatest influence on the bearing capacity of the pile

4. Manual operation will definitely have a period of fatigue, especially in the process of filling and compaction, which will easily cause work-related accidents or quality accidents
