Rapid tamping device and construction method

Abstract

The invention discloses a rapid tamping device and a construction method. The rapid tamping device comprises a tamping plate, lifting plates, reinforcing plates, a positioning cylinder, connecting buckles, bolts, nuts, iron chains, a connecting hammer head and an impact drill. The device is characterized in that exhaust pressure relief holes are machined in the upper half part and the lower half part of the tamping plate, the positioning cylinder is welded to the middle position of the tamping plate, the two reinforcing plates are welded in the longitudinal direction of the tamping plate, thetwo lifting plates are welded in the middle transverse position of the tamping plate, a lifting hole is formed in the middle of each lifting plate, and the connecting buckles and the lifting plates are connected through the lifting holes, the bolts and the nuts; and the iron chains are arranged on the upper parts of the connecting buckles in a matched manner, the other ends of the iron chains aremounted on the impact drill, the connecting hammer head is inserted into the positioning cylinder for positioning, the tamping plate is hoisted through the iron chains on the two sides, and the otherend of the connecting hammer head is connected with a cantilever of an excavator. The rapid tamping device has the advantages of simple structure, convenient operation, strong applicability, no site limitation, high construction efficiency, short construction time, reduced working strength of operators and improved safety.

Description

technical field [0001] The invention relates to the field of building foundations, in particular to a rapid compaction device and a construction method. Background technique [0002] Building foundations are divided into natural foundations and artificial foundations. The foundation that can directly bear the load of the building without treatment is called the natural foundation, and conversely, the foundation that needs to be treated by the foundation treatment technology is called the artificial foundation. [0003] The artificial foundation is the foundation that can only be built after the soil quality of the natural soil layer is too weak or unfavorable geological conditions, and needs artificial reinforcement or treatment. In the case of poor geological conditions, such as slopes, sandy land or silt geology, or although the soil texture is good, but the upper load is too large, in order to make the foundation have sufficient bearing capacity, it is necessary to use a...

Problems solved by technology

[0005] The invention provides a rapid compaction device and a construction method. In order to solve a series of technical problems caused by the traditional compaction equipment in the working process, a combination of a compaction plate and a percussion drill is adopted to quickly compact the backfill. On the ground, the tamping device has a simple structure, flexible and convenient operation, and is not prone to mechanical failure. The combination of the tamping device and the excavator can move flexibly, facilitate rapid movement and switch angles, greatly speed up the construction speed of the tamped foundation, and improve the The compaction efficiency shortens the construction time, and this compaction device has lower technical requirements for the operator, which reduces the construction strength of the workers and improves the work efficiency of the workers
