Pile body pneumatic reinforcement method

Abstract

The invention discloses a pile body pneumatic reinforcement method. The pile body pneumatic reinforcement method includes the steps that holes with the specified quantity, angle and depth are drilledon an original pile body to form a bottom-up channel; in the channel, a water seepage pipe wound with a filter screen is put into the channel to collect infiltration water; water outlet pipes and an air inlet pipe are connected and tied together with elbows; the water outlet pipes and the air inlet pipe are inserted into the water seepage pipe; all water outlet pipes are connected in series with pipes to be connected with a waste water collecting tank outside the pile body; concrete pouring is used for the joint of a channel mouth and the pipes; a newly arranged impermeable layer is laid on the original pile body; and an installation machine room is connected with an air inlet system and the air inlet pipe. The pipe body is solidified by extracting the water from the original pile body, the intensity of the pile body is strengthened, the pile body pneumatic reinforcement method has the characteristics of high operational reliability, re-stockpiling on the original pipe body, resistanceto settlement deformation of the pipe body and corrosion resistance.

Description

technical field [0001] The invention belongs to a reinforcement method for stockpiling of mine tailings in industrial solid waste, stockpiling of chemical waste slag and stockpiling of domestic garbage in domestic solid waste, and specifically refers to a method for pneumatically reinforcing piles. Background technique [0002] At present, most mine tailings ponds have problems such as low initial dam body strength, impervious tailings ponds, and insufficient stockpiling capacity; chemical waste slag yards and domestic waste landfills that are surrounded by anti-seepage membranes also have varying degrees However, there are problems of low strength of the pile body and leakage at the bottom, which can easily cause safety accidents such as pile body collapse and environmental pollution. The existing treatment method is to drill holes on the pile body and lower the submersible pump to pump water outward. The disadvantage of this method is that 1. The water pump has poor corros...

Problems solved by technology

[0002] At present, most mine tailings ponds have problems such as low initial dam body strength, impervious tailings ponds, and insufficient stockpiling capacity; chemical waste slag yards and domestic waste landfills that are surrounded by anti-seepage membranes also have varying degrees However, there are problems of low strength of the pile body and leakage at the bottom, which can easily cause safety accidents such as pile body collapse and environmental pollution. The existing treatment method is to drill holes on the pile body and lower the submersible pump to pump water outward. The disadvantage of this method is that 1. The water pump has poor corrosion resistance, and the damage is not easy to repair

2. The drainage effect is not good or it is easy to fail after the pile body settles and deforms

3. The upper part of the pile cannot continue to pile up solid waste, causing the area of ​​the solid waste pile to become larger and larger, thereby causing environmental pollution
