Abstract
The invention discloses a mounting method of a conveying pipe for solid filling material. The conveying pipe for solid filling material is mounted in a borehole vertically drilled. Preparations such as borehole inclination measuring and borehole smoothing are done before the mounting of feed pipes; a bottom feed pipe is mounted, the bottom feed pipe is lifted to an upper opening of the borehole by using a crane, the bottom feed pipe is fastened with a hoop, a next feed pipe is then aligned and welded to the bottom feed pipe, inclination measuring is performed on the feed pipes mounted, and all feed pipes are cyclically lowered in succession; finally, feed pipe wall post-grouting and fixation are finished by using a drill pipe. Since the conveying pipe for solid filling material is long and heavy, the method enables the safe, quick mounting of the conveying pipe for solid filling material, thus giving a greatly shortened well completion period.

Background technology
Filling mining technology is domestic and international mine for controlling a kind of method that strata movement and subsidence adopt, solid filling exploitation is a kind of new method of development in recent years, namely ground spoil is utilized, loess, the solids such as flyash are filled in underground goaf, therefore, solid filling thing must be transported to down-hole, by playing vertical feeding boring from ground, solid filling thing is directly thrown in down-hole, in order to ensure the throughput of solid filling material, feed intake boring in solid filling material conveyance conduit has been installed, and adopt the high-strength abrasion-proof pipeline of special manufacture, larger owing to vertically throwing in distance, general from 200m ~ 800m not etc., cause solid filling material conveyance conduit weight huge, usually the weight of every 100m just reaches more than 70t, in solid filling material conveyance conduit installation process, huge weight drastically influence installation safety and the efficiency of pipeline.Installing safely and fast to realize solid filling material conveyance conduit, ensureing to feed intake one-tenth well duration of well, have employed this mounting method.
Summary of the invention
Technical problem: the object of the invention is the deficiency overcome in prior art, provides a kind of method simple, safe and reliable, efficiency guaranteed solid filling material conveyance conduit mounting method.
Technical scheme: solid filling material conveyance conduit mounting method of the present invention, comprises the boring of vertically digging to down-hole along rock stratum, carries out deviational survey to boring and along behind hole, in the boring of vertically digging along rock stratum, installs commissioning pipe;
First suspend coxopodite commissioning pipe in midair with crane to transfer in boring, when coxopodite commissioning pipe upper port is positioned at boring upper port position, has adopted clip to be fixed on operating platform by the upper port of coxopodite commissioning pipe, unclamp crane lifting rope; Having suspended next joint commissioning pipe again in midair transfers to lower port and coxopodite commissioning pipe upper port place, alignment is firm welding also, two commissioning pipes that butt welding connects carry out deviational survey, unclamp clip, transfer commissioning pipe, until when next joint commissioning pipe upper port is positioned at boring upper port position, clip is adopted to be fixed on operating platform by the commissioning pipe upper port of continued access, go round and begin again, continuous continued access one saves commissioning pipe, until the commissioning pipe completed in whole boring is installed;
After commissioning pipe installation, in commissioning pipe, transfer the kickboard be connected with slip casting drilling rod, utilize slip casting drilling rod to be injected in the space between boring and commissioning pipe by kickboard by slurries, after grout cures, remove slip casting drilling rod, complete commissioning pipe installation work.
The described length often saving commissioning pipe is 5m ~ 10m; Two commissioning pipes that described butt welding connects carry out deviational survey, and its gradient is not more than 1 ‰, should adjust immediately if be greater than this value.
Beneficial effect: the present invention, by boring deviational survey and suitable hole in advance, transfers commissioning pipe section by section by crane and clip, adopts and cut open weldering welding procedure, achieve solid filling material carrier pipe and install safely and fast.This not only ensures the Completed advance rate fed intake in well construction, also for the installing engineering of domestic and international conditions of similarity pipe fitting provides technological borrowing, its method is simple, and easily construct, successful, has practicality widely.
