Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0026] A heating and consolidation construction method for a vertical drainage filter pipe with a built-in electric heating rod, comprising a vertical drainage filter pipe 1 and an electric heating rod 2 for being built into the vertical drainage filter pipe;

[0027] The vertical drainage filter pipe is composed of a permeable bellows 1-1 and a polyester spunbonded non-woven fabric 1-2 wrapped around the permeable bellows. The permeable bellows are formed of high-density polypropylene (PPR) and have a Corrugated new plastic drainage pipes, the grooves of the permeable corrugated pipes are evenly distributed with 1-3 permeable through holes, and the surroundings of the permeable corrugated pipes are covered with polyester spunbonded non-woven fabrics; the diameter of the vertical drainage filter pipe is preferably 30mm, and other technical indicato...

Abstract

The invention discloses a heating consolidation construction method for arranging a built-in electric heating rod in a vertical drainage filter tube. The vertical drainage filter tube is sleeved witha sleeve firstly, the bottom end of the vertical drainage filter tube is ironed level through a heat sealing machine, so that weak soil is prevented from entering the filter pipe; through a plate inserting machine or manual work, the sleeve is beaten to an appointed depth, the sleeve is then pulled out, the vertical drainage filter pipe is kept in a soil body, the vertical drainage filter pipe iscut off, and a sand cushion is exposed at the top end of the vertical drainage filter pipe; an electric heating rod is inserted into the vertical drainage filtering pipe, the electric heating rod is connected through a lead wire of an insulated waterproof rapid plug, the insulated waterproof rapid plug is connected with a rapid connector of a T cable, and the T cable is connected with a power supply system; a foundation is heated through the electric heating rod, through pile preloading or vacuum preloading or vacuum and pile combined preloading or other methods, preloading drainage consolidation is conducted on the foundation.

Description

technical field [0001] The invention belongs to the field of civil engineering foundation treatment, and in particular relates to a heating and consolidation construction method with built-in electric heating rods in vertical drainage filter pipes. Background technique [0002] Drainage consolidation method is widely used in soft clay foundation treatment. In order to shorten the drainage path and reduce the consolidation time, vertical plastic drainage boards need to be driven into the foundation. The plastic drainage board is a strip-shaped composite structure, with an extruded plastic core board in the middle, and the two sides of the core board are wrapped with non-woven geotextile as a filter layer. The plastic drainage board is generally inserted into the casing first, and the casing is driven into the specified depth through the plug-in machine, and then the casing is pulled out, and the plastic drainage board is left in the soil. The plane is generally arranged in a...
