Abstract
The invention discloses an in-hole blocking method for chemically grouting a deep hole with epoxy resin. In the in-hole blocking method, a slurry inlet pipe, a hydraulic or pneumatic grouting plug, a connecting ring arranged on the upper part of the grouting plug, a traction steel wire rope, an auxiliary winch, a slurry returning soft pipe, and a slurry returning pipe inside a grouting segment are used. The in-hole blocking method is applicable to chemical grouting of the deep hole which is deeper than 100m; the in-hole blocking method comprises a segmental blocking step, and a blocking step similar to hole opening sealing. Through the in-hole blocking method, the plug burying probability can be reduced and the quality of a grouting project can be ensured.
Description
Technical field
The present invention relates to a kind of for epoxy grouting hole internal congestion method.Be adapted to the epoxy resin Deep hole chemical grouting hole internal congestion of hole depth more than 100m especially.
Background technology
Epoxy resin is a kind of conventional chemical grouting material, is mainly used in the permanent disposal of Geological Defects within the scope of water-control project dam dam site.This material is after repeatedly improveing, and function admirable, concrete castability is good, but expensive.Epoxy resin is adopted to carry out basement rock chemical grouting, the general construction method adopting " small diameter hole, from top to bottom segmentation block grouting ".Because epoxy resin grout material has higher permeability, in deep hole (hole depth is more than 100m), long-time, high pressure filling process, easily there is " around plug " phenomenon in slurry material, and is not easily found, and in causing hole, " burying plug " accident occurs.Not only the difficulty of accident settlement is comparatively large, also can have influence on construction speed and chemical grouting workmanship simultaneously.。
Summary of the invention
In order to overcome the deficiency adopting traditional simple " from top to bottom segmentation obstruction " construction method, technical problem to be solved by this invention is to provide a kind of chemical grouting hole internal congestion method, can reduce " burying plug " probability, guarantee grouting works quality.
The object of the present invention is achieved like this:
A kind of method for epoxy resin Deep hole chemical grouting hole internal congestion, comprise slurry recovering tube in inlet pipe, hydraulic pressure or air pressure packer, the connecting ring of packer top processing, haulage cable, auxiliary elevator, overfall flexible pipe and grout compartment, it is applicable to carry out the Deep hole chemical grouting of hole depth more than 100m, and it comprises segmentation blocking step and " similar aperture is closed " blocking step;
Described segmentation blocking step is: each grout compartment within hole depth 100m time, adopts φ 76mm borehole, φ 67mm hydraulic pressure or air pressure packer to carry out blocking, packer grouting from top to bottom, carries out time construction of next section after grout compartment grout cures again;
Described " similar aperture is closed " blocking step: hole depth is secondary more than grout compartment each after 100m, adopt φ 56mm-φ 60mm small diameter hole, repeated by packer to be blocked in hole depth 100m place, in following section of elongated hole, slurry recovering tube is in the milk, and slurry recovering tube is down to 20cm place at the bottom of hole;
In above-mentioned segmentation blocking step and " similar aperture is closed " blocking step, in order to strengthen promoting packer ability, after hole depth 60m, inlet pipe adopts rigid pipe to substitute packer flexible pipe, and at packer top processing connecting ring in above-mentioned " similar aperture is closed " blocking step, adopt wire rope traction elevator assisted Extraction to rise and pull out packer;
Epoxy grouting hole internal congestion construction task is completed by said method.
The present invention achieves following technique effect:
(1) adopt φ 67mm hydraulic pressure or the grouting of air pressure packer jam, can 3.5 ~ 4.0MPa grouting pressure be met, do not produce " sliding plug " accident simultaneously;
(2) following section of hole depth 100m employing " method is closed in similar aperture " grouting, and be equipped with elevator assisted Extraction rise pull out packer, decrease Deep hole chemical grouting and bury plug probability;
(3) construct with complete opening " method is closed in aperture " and compare, hole section accounts for slurry and relatively reduces, and has saved material cost;
(4) packer divides into degree of depth reduction, reduces non-cutting time, and efficiency of construction improves;
(5) hole depth 100m is with the secondary repeatedly re grouting of hypomere, and grouting quality is more reliable.

Described segmentation blocking step is: each grout compartment within hole depth 100m time, adopts φ 76mm borehole, φ 67mm hydraulic pressure or air pressure packer to carry out blocking, packer grouting from top to bottom, carries out time construction of next section after grout compartment grout cures again;
Described " similar aperture is closed " blocking step: hole depth is secondary more than grout compartment each after 100m, adopt φ 56mm-φ 60mm small diameter hole, repeated by packer to be blocked in hole depth 100m place, in following section of elongated hole, slurry recovering tube is in the milk, and slurry recovering tube is down to 20cm place at the bottom of hole;
In above-mentioned segmentation blocking step and " similar aperture is closed " blocking step, in order to strengthen promoting packer ability, after hole depth 60m, inlet pipe adopts rigid pipe to substitute packer flexible pipe, and at packer top processing connecting ring in above-mentioned " similar aperture is closed " blocking step, adopt wire rope traction elevator assisted Extraction to rise and pull out packer;
Epoxy grouting hole internal congestion construction task is completed by said method.
