Abstract
The invention relates to mine contractible composite shaft lining sliding layer composite material and the preparing technology. Its material weight ratios are follows: asphalt 1, expanded perlite 0.25-0.52, and fly ash 0.7-1.5. The preparing technology includes the following steps: heating the asphalt to 130-160 degree centigrade; adding the expanded perlite and fly ash into stirrer to form aggregate; adding the heated asphalt into the stirrer to mix; discharging the mixture into cooling groove and cooing to 20-30 degree centigrade to process packing compact; pressing to 2.0 megapascal to do forming and mold casting; the size of the finished product is blocky with 400*300*70 centimeter. The invention has the advantages of high strength, good buffering effect, simple construction, uneasy water seepage and fracture, and low cost etc.
Description
Affiliated technical field
The present invention relates to a kind of mine contractible combined wall sliding layer composite material, especially a kind of is the borehole wall sliding layer matrix material of main raw material with the pitch prill.
Background technology
At present; the general freezing process that adopts of mine pit shaft design; double steel bar concrete structure; in order to guarantee pit shaft safety; between the inside and outside borehole wall, add sliding layer; and external wall section and intersegmental horizontal contractibility buffer layer is set; sliding layer between the pit shaft inside and outside wall mainly plays the slippage shock absorption, and when the native sedimentation of table, the unlikely drive inwall of outer wall wrecks; the main effect of contractibility buffer layer is between the pit shaft external wall section; when outer wall sinks, play shock absorption, displacement is concentrated on the layer that can contract, absorb with the protection borehole wall by the layer material that can contract and be not damaged; thereby the requirement layer material that can contract has certain intensity and can the amount of contracting, and this material will have certain water resistance.Usually pitshaft sliding layer design, adopt inside and outside two-layer reinforced concrete structure, two interlayers are done the sliding layer material with the PS plate, and cement and water glass mixing grouting and water-proof structure are because PS plate intensity is low, when the native sedimentation of table, outer wall sinks, and the PS plate is damaged, and does not have shock absorption, and serious phenomenon of rupture appearred in the borehole wall in pit shaft easily seeped water, causes, and the PS plate belongs to light material transportation difficulty.
Summary of the invention
In order to overcome the deficiency that prior art exists; the invention provides a kind of mine contractible combined wall sliding layer composite material and preparation technology; this matrix material and preparation technology can not only substitute prior art; and buffering the outer borehole wall sinks during because of the sedimentation of pit shaft table soil that the borehole wall sinks in the unlikely drive; the good buffer effect of the borehole wall in the protection is difficult for infiltration, fracture.
The technical solution adopted for the present invention to solve the technical problems is, it is made of than part starting material following weight, 1 part of pitch prill, pearlstone 0.25-0.52 part and flyash 0.7-1.5 part, its preparation technology is warming up to behind the 130-160 degree stand-by for the pitch prill heating tank that will fill pitch prill earlier, getting pearlstone 0.25-0.52 part and flyash 0.7-1.5 part enters stirrer and is stirred into aggregate, pitch after the heating is got 1 part of pitch prill through pitch prill pump and timing meter and is entered stirrer stirring formation compound, compound is discharged at and is cooled to 20-30 degree dress mould in the compound cooling groove, pressing machine is forced into 2.0 MPas and is shaped to take off and touches, finished product is 400 * 300 * 70 centimetres of bulks, every cubic metre of unit weight 1-1.3 ton, draught is greater than 50 percent, ultimate compression strength is greater than 2.0 MPas, and shearing resistance is greater than 0.552 MPa.
The invention has the beneficial effects as follows, can be when substituting prior art, also having the pitch prill of employing, pearlstone and flyash is starting material, glued contractibility is good, intensity is high, and good buffer effect, and construction is simple, be difficult for infiltration, fracture, fly ash material be easy to get and cost low.
