Abstract
The invention relates to a renewable unidirectional injector for crack, comprising connecting tube, hollow injecting body, and elastic soft layering. Connecting tube is set on two ends of hollow injecting body. Several injecting branch holes, which are connected with inner hole of hollow injecting body, are set on the outer surface of hollow injecting body. Elastic soft layering, which is pressedto all injecting branch holes in ordinary status, is mated round the hollow injecting body tightly. It can compensate concrete crack ideally and when the crack appears again it is compensated by injector again.
Description
Technical field:
The present invention relates to a kind of concrete pouring thing device for fracturing that remedies, relate in particular to the distress in concrete slurry casting machine.
Background technology:
In large-scale concrete engineerings such as dam, subway, tunnel, power plant, basement, between concrete and rock, be easy to produce the crack between concrete and the steel plate; Between concrete and concrete owing to be subjected to the influence of factors such as different geology, the concrete pouring thing in different locations can produce different sedimentations, also can produce the crack, this is the common deficiency in the concrete pouring thing, and it directly affects the quality and the service life of concrete pouring engineering, in order to remedy the crack, people will have crack section people usually for breaking, carry out concrete pouring then, the mode that remedies the crack so both required great effort, time-consuming, uneconomical again.
Summary of the invention:
The purpose of this invention is to provide a kind of reusable unidirectional grout device, it can be fast, economically distress in concrete is carried out slip casting repairs, and reusable.
Reusable unidirectional grout device of the present invention, comprise sealing-plug, tube connector, the hollow injecting cement paste, elastomeric flexible press strip and Grouting Pipe, tube connector is arranged on the two ends of hollow injecting cement paste, be connected to the Grouting Pipe that has sealing-plug in the outer end of arbitrary tube connector, outer end at the tube connector of the other end is connected to the Grouting Pipe that links to each other with grouting pump, on the external surface of hollow injecting cement paste, offer some slip castings and propped up the hole, the slip casting main aperture of slip casting Zhi Kongyu hollow injecting cement paste communicates, the elastomeric flexible press strip is enclosed within on the hollow injecting cement paste, and limit by the positioning step at two ends, the left and right sides, the elastomeric flexible press strip is pushed down all slip casting under normal conditions and is propped up the hole.
The cross sectional shape of described hollow injecting cement paste is circle or regular polygon, and the diameter of bore of hollow injecting cement paste is 6～100 millimeters, preferred 10～50 millimeters.
Using method of the present invention is as follows: offer a hole at the distress in concrete place, the present invention is put into this hole, be enclosed within Grouting Pipe on the tube connector at hollow injecting cement paste two ends, one end is blocked with sealing-plug, the other end links to each other with grouting pump, with grouting pump pressure injection injection slurry in the hollow injecting cement paste, injection slurry props up the hole through Grouting Pipe, tube connector inflow hollow injecting cement paste endoporus, slip casting, when grouting pressure reaches predetermined pressure, injection slurry is washed elastic layering open from slip casting Zhi Kongzhong ejection, fills the crack between two concrete.When injection slurry exposes when partly excessive from coagulating the soil cracking seam, remove grouting pump, use vacuum pump instead, the slip casting main aperture of Grouting Pipe and the sucking-off of slip casting Zhi Kongzhong injection slurry, open sealing-plug then, use high-pressure hydraulic pump water filling in Grouting Pipe again, the hole is propped up in slip casting main aperture and slip casting clean.Can not only remedy distress in concrete ideally like this,, also can carry out repetition slip casting to crack herein and remedy by the present invention even the age crack occurs after permanent again.
