Abstract
The invention relates to an annular filling method between freezing pipes and surrounding rocks, comprising the preparation of cement slurry and the filling method. In the procedure of preparing cement slurry, the materials, that is, cement, water, clay or bentonite, retarder, alkali powder, amine powder, nitrile powder, are stirred evenly pro rata. The filling method comprises the following steps. The first step is to regulate the clay slurry inside the freezing hole after final hole and to stop when the specific gravity of the clay slurry from the freezing hole is 1.05-1.15g per cubic centimeter. The second step is to bring forward the drilling tool, remove the drill bit, place down the hollow drill rod, start the mud pump, and press the stirred cement slurry inside the slurry storage pool from the mud pump into the bottom of the freezing hole through the drill rod to be replaced by the clay slurry. The dosage of the cement slurry is 3-8m per cubic centimeter every freezing hole. The third step is to draw out the hollow drill rod, place down the freezing pipe, and extrude the cement slurry to fill the annular space between the freezing pipe and the surrounding rock. The annular filling method between freezing pipes and surrounding rocks has the advantage of solving the hidden danger of well submerging accident between the freezing pipes and the surrounding rocks due to transfixion between upper and lower sewage caused by bad filling.
Description
Technical field
The present invention relates to the method for annular filling between a kind of freezing pipe and country rock.
Background technology
At present, adopt in the construction freezing method at full pit shaft, freezing pipe must pass structure such as the ingate, sump, shaft station, connection roadway of construction in later period, and adopting freezing process is can safe driving and masonry construction under the frost wall protection that forms.Problem is after frost wall thaws naturally, and big water gaging in the stratum and silt particle must pour in the structure such as ingate of construction in later period by the annulus of freezing pipe and country rock, and the lighter destroys structure structure, and weight person causes major accidents such as flooding well.For this reason, in the mine pit shaft is built, at the geology and the hydrogeological conditions of bad ground, according to the moisture abundant characteristics of table soil and basement rock with along with the exploitation of deep layer mineral reserve, the continuous deepening of pit shaft is for guaranteeing the pit shaft smooth construction, normal employing table soil section is freezed, and the method for rock section slip casting is passed through, though freezing pipe does not penetrate the down-hole, there is not the water guide problem, increases claim for eot but its shortcoming is a construction technology, speed of shaft sinking is slow, input is many, the expense height, and the slip casting section can not realize beating dry-well fully.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides the method for annular filling between a kind of freezing pipe and country rock, it has solved between freezing pipe and the stratum country rock and to have caused because of filling is bad that underground water is ganged up up and down and cause the hidden danger of flooding the well accident.
The present invention solves the technical scheme that its technical problem takes: comprise the following steps:
1., raw material is cement, water, clay or swell soil, retarding agent, ground caustic, amine powder, nitrile powder (1), the preparation of cement grout:, water: cement is 1: 0.5～1: 1; Clay or bentonite consumption are the 5%-10% of cement consumption; Retarding agent is the 2.5%-3% of cement consumption, and ground caustic, amine powder, nitrile powder are 1% of cement consumption, more than are weight ratio; 2., described raw material poured in the stirring pool in described ratio stirred 2-10 minute, put into pulp storage tank after stirring;
(2), placement method: 1., behind the whole hole of freezing hole, inject the clay slurry rarer, treat that from the clay slurry proportion that freezes to flow out in the aperture be 1.05-1.15g/cm than virgin pulp liquid to freezing hole
3In time, stop, and the performance of former clay slurry is: proportion 1.1-1.2g/cm
3, sand content is no more than 4%, and fluid loss is no more than 25ml, and colloidity is not less than 95%; 2., drilling tool is proposed, lay down drill bit, the underlying hollow drill stops behind the 5-8m at the bottom of the freezing hole, the slush pump grout outlet is communicated with the upper end sealing of hollow drill with pressure duct, slurry pumping port is communicated with described pulp storage tank sealing, start slush pump, displace clay slurry at the bottom of the cement grout that stirs in the pulp storage tank is pressed into freezing hole by slush pump by hollow drill, the consumption of cement grout is each freezing hole 3-8m
33., extract hollow drill, the underlying freezing pipe makes the cement paste squeeze pack in freezing pipe and country rock annulus.
The present invention has following advantage: 1, solved between freezing pipe and the stratum country rock and to cause because of filling is bad that underground water is ganged up up and down and cause the hidden danger of flooding the well accident, filled up a domestic similar blank freezing well construction; 2, with clay slip in the cement paste displacement freezing borehole, technology is simple and can guarantee that freezing pipe transfers normally carrying out of operation; 3, duration weak point, cost is low, easily promotes the use of.
