Presoaking dynamic compaction treatment device and method capable of improving foundation bearing capacity

Abstract

The invention discloses a presoaking dynamic compaction treatment device and method capable of improving the bearing capacity of a foundation, belongs to the technical field of dynamic compaction treatment, and aims to solve the problems that a pounder has a balance debugging process at a high position and stays at the high position for a period of time, workers, unconscious people and the like in a construction site easily walk to the lower end of the pounder under the unconscious condition, and the pounder cannot be damaged. If an equipment operator does not notice the problem of people at the lower end of the rammer; the movement range of the rammer is limited through the contour limiting base ring and the supporting frame, so that a worker is prevented from walking to the lower end of the rammer under the unconscious condition; the guide insertion rod is stably clamped in the splicing lug ring, then the rammer and the clamping and locking assembly are fixed to complete follow-up construction, through clamping connection of the auxiliary reinforcing assembly and the plate body, the connecting column is indirectly clamped, the stressed position is kept balanced, and the acting force of the self weight of the rammer on a component is reduced.

Description

technical field [0001] The invention relates to the technical field of dynamic compaction treatment, in particular to a presoaked water dynamic compaction treatment device and method capable of improving the bearing capacity of foundations. Background technique [0002] The dynamic tamping method is the powerful tamping method, also known as the dynamic consolidation method. It uses a large crawler-type dynamic tamping machine to freely drop an 8-30-ton heavy hammer from a height of 6-30 meters to compact the soil and rapidly improve the foundation. Bearing capacity and compression modulus form a relatively uniform and dense foundation, which changes the pore distribution of the foundation soil within a certain depth of the foundation. The dynamic compaction method has been widely used in expressway railways, airports, nuclear power plants, large industrial areas, and ports. Foundation reinforcement projects such as sea reclamation have the advantages of short construction p...

Problems solved by technology

[0003] The dynamic tamping machine naturally drops the rammer from a height of tens of meters, and uses the high impact force generated by the high drop of the hammer to change the pore distribution of the foundation soil. However, the rammer will have a balance adjustment process at a high place, so it will Staying at a high place for a period of time, the staff on the construction site and other people tend to walk to the lower end of the rammer unconsciously. If the equipment operator does not notice the people at the lower end of the rammer, the consequences will be disastrous. After the machine has formed several pits, it needs to be flattened and a layer of material re-laid to strengthen the bearing capacity of the foundation. The construction period is long, and during the decoupling process of the rammer, the self-weight of the rammer gradually wears the hook After long-term use, there will be a gap in the hook, which will easily cause the shaking of the tamper, and the danger of the equipment will increase.
