Abstract

A renewable crack one-way grouting device includes a connecting pipe, a hollow grouting body and an elastic soft layering. The connecting pipe is arranged on the two ends of the hollow grouting body, a plurality of grouting branching holes are arranged on the external surface of the hollow grouting body, the grouting branching hole is communicated with the inner hole of the hollow grouting body, the elastic soft layering is tightly covered around the hollow grouting body, and the elastic soft layering tightly press on all the grouting branching holes under normal pressure. The utility mode can ideally cover the concrete crack. Even if the crack comes out subsequently, the grouting device can be used for repeat grouting of the crack.

Description

Reusable unidirectional grout device

Technical field:

The utility model relates to a kind of concrete pouring thing device for fracturing that remedies, and relates 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 utility model provides a kind of reusable unidirectional grout device, and it can be fast, economically distress in concrete is carried out slip casting repairs, and reusable.

Reusable crack described in the utility model unidirectional grout device, comprise tube connector, hollow injecting cement paste, elastomeric flexible press strip, tube connector is arranged on the two ends of hollow injecting cement paste, on the external surface of hollow injecting cement paste, offer some slip castings and propped up the hole, the endoporus of slip casting Zhi Kongyu hollow injecting cement paste communicates, the elastomeric flexible press strip tightly is enclosed within on the hollow injecting cement paste, and the elastomeric flexible press strip is tightly pushed down all slip casting under normal conditions and propped up the hole, and is limited by the localizer rank.

The cross sectional shape of described hollow injecting cement paste is any in circle, regular polygon, petal, the side cut circle, and the diameter of bore of hollow injecting cement paste is 6～100 millimeters, preferred 10～50 millimeters.

Using method of the present utility model is as follows: offer a hole at the distress in concrete place, reusable crack described in the utility model unidirectional grout device is put into this hole, tightly 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 is through Grouting Pipe, tube connector flows into hollow injecting cement paste endoporus, the hole is propped up in 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 utility model even the age crack occurs after permanent again.

The specific embodiment:

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated:

Reusable crack described in the utility model unidirectional grout device, as accompanying drawing 1, shown in Figure 3, it is by sealing-plug 1, tube connector 2, hollow injecting cement paste 3, elastomeric flexible press strip 4 is formed, tube connector 2 is arranged on the two ends of hollow injecting cement paste 3, on the external surface of hollow injecting cement paste 3, offer 16 slip castings and propped up hole 32, on the end face of hollow injecting cement paste 3, be provided with four fabrication holes 34, to reduce the materials of hollow injecting cement paste 3, slip casting is propped up hole 32 and is communicated with the slip casting main aperture 31 of hollow injecting cement paste 3, elastomeric flexible press strip 4 tightly is enclosed within on the hollow injecting cement paste 3, elastomeric flexible press strip 4 presses all slip casting under normal conditions and props up hole 32, and limit by the positioning step 33 at two ends, the left and right sides, the cross sectional shape of described hollow injecting cement paste 3 is a square, and the diameter of the slip casting main aperture 31 of hollow injecting cement paste 3 is 50 millimeters, and the diameter that hole 32 is propped up in slip casting is 1.5 millimeters.

Embodiment of the present utility model is a lot, and the cross sectional shape of hollow injecting cement paste 3 can design arbitrarily, and accompanying drawing 2, Fig. 4 are two kinds of embodiment in addition wherein.
