Abstract
The invention discloses a drilling expansion method for a rock layer top pipe. The drilling expansion method comprises the following construction steps that a small off-axis water drilling machine is used for conducting drilling, digging and coring along the periphery of a pipeline planned to be dug, and the off-axis water mill drilling machine can make the included angle between a drill pipe and the wall of the pipeline to be decreased to be about 5 degrees; after drilling, digging and coring are carried out on the periphery of a pipeline planned to be jacked, a rock mass planned to be dug is made to form a barrel-shaped annular free face, and in other words, a rock core column is formed in the center of the pipeline planned to be dug. The drilling expansion method has small influences on surroundings and has safety, the economy of the rock layer top pipe in the drilling expansion method is better, the method is feasible, and the project time limit is greatly shortened.
Description
Technical field
The present invention relates to push pipe field, rock stratum, specifically belong to a kind of swollen method of brill for rock stratum push pipe, within being applicable to well segment distance 140m, the rock stratum push pipe of caliber 800mm ~ 1200 mm; Each rocks of below 60MPa.
Background technology
In prior art, in the work progress of rock stratum push pipe, there is following shortcoming:
1, method abolished by artificial pneumatic pick: rock strength is large, and unsuitable broken, construction speed is slow; 2, blasting procedure: pipeline is positioned at resident and goes or factory district, does not allow to adopt; 3, laccolite push-bench method: need after the cutterhead jacking certain distance of (1), laccolite push-bench front end to change, when being less than 1.2m diameter push pipe, cannot entering people and change, and its jacking distance is just restricted; (2), the cutterhead all more expensive (about 2,500 ten thousand yuan/cover) of laccolite push-bench equipment and replacing, uneconomical.
Summary of the invention
The object of this invention is to provide a kind of swollen method of brill for rock stratum push pipe, very little on surrounding enviroment impact, have safety, bore in the push pipe economy of swollen method rock stratum more excellent, method is feasible, the duration shortened greatly.
Technical scheme of the present invention is as follows:
A kind of swollen method of brill for rock stratum push pipe, include following construction sequence: utilize small-sized different axle water drilling machinery to bore along the periphery of intending excavation pipeline and take core, different axle water mill rig can make the angle of drilling rod and duct wall be contracted to about 5 degree, plan jacking pipeline periphery is bored after taking core, make plan excavate rock mass and form barrel-shaped ring-type free face, namely rock stem stem is defined in the central authorities intending excavation pipeline, then in the middle of stem stem, the swollen hole of wedge is bored, hammering iron wedge in hole, take out after utilizing wedge expansive force that swollen for stem stem solution is become some pieces, thus form push pipe duct.
Advantageous Effects of the present invention is as follows:
1, compared with drilling and blasting method push pipe, bore swollen method rock stratum push pipe noise and shake all very little, very little on surrounding enviroment impact, there is safety.
2, compared with laccolite push-bench push pipe, bore in the push pipe economy of swollen method rock stratum more excellent, method is feasible.
3, compared with pneumatic pick crush method, the duration shortened greatly.
Should after method of the present invention, Ming Chuan township Middle St 1#-7# well section about 400 meters of push pipes are positioned at harder quartz sand rock stratum, adopt brill swollen method rock stratum jacking construction to substantially reduce the duration, every complete equipment day jacking about 1.5 meters, and adopt pneumatic pick broken France and Japan jacking about 0.5 meter.
Accompanying drawing explanation
Fig. 1 is processing step block diagram of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of swollen method of brill for rock stratum push pipe, include following construction sequence: utilize small-sized different axle water drilling machinery to bore along the periphery of intending excavation pipeline and take core, different axle water mill rig can make the angle of drilling rod and duct wall be contracted to about 5 degree, plan jacking pipeline periphery is bored after taking core, make plan excavate rock mass and form barrel-shaped ring-type free face, namely rock stem stem is defined in the central authorities intending excavation pipeline, then in the middle of stem stem, the swollen hole of wedge is bored, hammering iron wedge in hole, take out after utilizing wedge expansive force that swollen for stem stem solution is become some pieces, thus form push pipe duct.
Claims (1)
1. the swollen method of the brill for rock stratum push pipe, it is characterized in that, include following construction sequence: utilize small-sized different axle water drilling machinery to bore along the periphery of intending excavation pipeline and take core, different axle water mill rig can make the angle of drilling rod and duct wall be contracted to about 5 degree, plan jacking pipeline periphery is bored after taking core, make plan excavate rock mass and form barrel-shaped ring-type free face, namely rock stem stem is defined in the central authorities intending excavation pipeline, then in the middle of stem stem, the swollen hole of wedge is bored, hammering iron wedge in hole, take out after utilizing wedge expansive force that swollen for stem stem solution is become some pieces, thus form push pipe duct.
