Geotextile anti-blocking permeable pile construction device and method

Abstract

The invention discloses a geotextile anti-blocking permeable pile construction device and method. The problems in the prior art that a permeable pile is prone to being blocked and the water permeability is reduced in the construction process are solved, and the effects of ensuring the water permeability, reducing the entry of soil particles and avoiding the blockage of the permeable pile are achieved. According to the technical scheme, the geotextile anti-blocking permeable pile construction device comprises sleeves and pile tips which are connected detachably, protrusions matched with the sleeves are arranged on the top portions of the pile tips, and the protrusions are circumferentially provided with a plurality of first suspension parts which are arranged at intervals. The sleeves are connected with the pile tips through geotextile bags arranged at the bottom in a sleeving mode to prevent the blockage of the permeable pile in the construction process. Second suspension parts matchedwith the first suspension parts are arranged at the bottoms of the geotextile bags to ensure the geotextile bags to be closely connected with the pile tips.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a construction device and method for geotextile anti-clogging permeable piles. Background technique [0002] With the vigorous construction of infrastructure, composite foundation technology is developing rapidly in our country. A typical trend in the development of ground treatment in recent years is to continuously develop new ground treatment methods on the basis of existing ground treatment methods, especially the comprehensive use of various ground treatment methods, forming a very distinctive composite reinforcement technology . [0003] From the perspective of water permeability, the vertical reinforcement of composite foundation can be roughly divided into two types: water permeability and water impermeability. Permeable piles take into account both rapid drainage and high strength. Replacing other piles with permeable piles can improve the dynamic compressive and tensi...

Problems solved by technology

[0004] However, permeable piles will encounter clogging problems during the construction process, resulting in a decrease in their water permeability; during the consolidation process of the foundation, the mobile particles in the piping soil will also enter the pores of the pile material under the action of a sufficiently large seepage force , causing blockage; during an earthquake, the liquefaction of the foundation makes the soil flow or semi-flow state, and the flow of fine particles in the soil will also cause blockage of permeable piles
