Abstract
The utility model relates to a stop grouting plug for the orifice chemical grouting, which consists of inverted valve gland, a conical tube, an inverted valve, an orifice grouting and stopping plug body, a rubber bushing, a metal bushing and a ring nut. The retaining check valve and the check valve gland are arranged in the mortar outlet of the conical tube of the orifice grouting and stopping plug body; the rubber bushing, the metal bushing and the ring nut are arranged out of the plug body. The retaining check valve is arranged at the mortar outlet of the grouting and stopping plug so as to avoid slurry from leaking into the orifice. The mortar inlet of the stop grouting plug can be connected with the grouting pump through rapid joint so as to carry on grouting work, and the grouting flow can be reduced and the working efficiency can be largely improved. After the grouting is finished, the grouting tube can be directly dismounted, and the hole is unnecessary to bind, which reduces the complexity of the construction and saves the orifice pipe barring material. The utility model is of a low cost and a broad using range, which can be connected with the normal chemical grouting pump or manual pump and needs not to be fit with the special high pressure grouting pump.
Description
Technical field
The utility model relates to the distress in concrete treatment technology, and a kind of chemical grouting of using in distress in concrete processing procedures such as water conservancy and hydropower, traffic, coal, metallurgy, mine, historical relic and heritage buildings specifically is with the aperture stop grouting plug that is in the milk.
Background technology
The distress in concrete problem is a ubiquity and the engineering problem that is difficult to solve.The appearance of distress in concrete not only can reduce the impervious ability of building, influence the function of use of building, and can cause corrosion, the carbonization of concrete of reinforcing bar, reduce the durability of material, influence the supporting capacity of building, influence giving full play to of its application life and economic benefit, must attach great importance to, in time repair processing.
At present, engineerings such as most of water conservancy and hydropowers all adopt Chemical Grouting Treatment in handling distress in concrete infiltration construction.It is to utilize press device that chemical grouting material is pressed in the concrete crack, and chemical grouting material sclerosis back forms an integral body with concrete, thereby plays the purpose that shutoff is reinforced.
In the chemical grouting construction, adopt more method to have: pre-buried grout box method, pre-embedment grouting pipe method and high pressure Water slop injector method.Pre-buried grout box method and pre-embedment grouting pipe method all need to adopt epoxy mortar or material for quickly stopping leakage to carry out pre-buried to grout box or grout pipe, and after needing aperture pipe laying material solidification (generally needing the 1d left and right sides time) just can be in the milk, and after the grouting end, need grout hole to be sealed, flow backwards to prevent slurries with galvanized wire etc.
Though the high pressure Water slop injector is provided with unidirectional stop valve, can prevent that slurries from falling to spray under high pressure is pushed, but its unidirectional stop valve is located at the slurry inlet place, the grease nipple structures that adopt more, need higher pressure just can open (generally more than 4MPa), therefore need to be equipped with special-purpose high pressure grouting pump, and the grouting pressure of actual distress in concrete Chemical Grouting Treatment is less than 1MPa.Simultaneously, the high pressure Water slop injector is to utilize axial compression generation expanded radially to be out of shape to reach the purpose that slurry is ended in the aperture, needs to adopt the big gum sleeve of dilatancy.
Summary of the invention
Purpose of the present invention just provides a kind of chemical grouting with the aperture stop grouting plug that is in the milk, and this is a kind of simple in structure, easy to operate, low price, can improve the grouting stop grouting plug of construction quality and efficiency of construction.
The utility model is taked following design scheme: this utility model presses nut to form by non retern valve end socket, Taper Pipe, unidirectional non retern valve, aperture grouting stop grouting plug main body, gum sleeve, metallic gasket, metal sleeve, ring, and aperture grouting stop grouting plug main body has stock inlet and grout outlet.Aperture grouting stop grouting plug main body is made of plastic, cylindrical, and the one end is a Taper Pipe, is provided with unidirectional non retern valve in the Taper Pipe, is fixed by the non retern valve end socket that is connected in the Taper Pipe inner surface, and non retern valve end socket place establishes grout outlet.Aperture grouting stop grouting plug main body external surface suit gum sleeve and metal sleeve, the two is provided with metallic gasket.Grouting stop grouting plug main body stock inlet end outer surface thread connecting ring is pressed nut.
The stop grouting plug grout outlet end that can be in the milk in the aperture during construction directly inserts in the concrete grouting hole, presses nut by tightening ring, makes gum sleeve on the grouting stop grouting plug produce distortion by Taper Pipe and expands and be fixed in the grout hole.Unidirectional non retern valve is located at grouting stop grouting plug grout outlet, aperture spillage not in the time of can guaranteeing to be in the milk.Grouting stop grouting plug stock inlet end can by snap joint with carry out grouting construction after grout pump is connected rapidly, make the grouting procedure minimizing, greatly increase work efficiency.Grouting can directly shed grout pipe because of packer is provided with non retern valve after finishing, and the aperture need not colligation, reduces the construction complexity, saves aperture pipe laying material.This grouting stop grouting plug scope of application is wide, can link to each other with general chemistry grout pump or hand pump, need not to be equipped with special-purpose high pressure grouting pump.In addition, this packer low price, its unit price only are that the high pressure Water slop injector is about half.
Description of drawings
Fig. 1 is the utility model chemical grouting with aperture grouting stop grouting plug schematic diagram.
The specific embodiment
As shown in Figure 1: a kind of chemical grouting is with the aperture stop grouting plug that is in the milk, press nut (8), stock inlet (9) and grout outlet (10) to form by non retern valve end socket (1), Taper Pipe (2), unidirectional non retern valve (3), aperture grouting stop grouting plug main body (4), gum sleeve (5), metallic gasket (6), metal sleeve (7), ring, aperture grouting stop grouting plug main body (4) is cylindrical, the one end is Taper Pipe shape (2), be provided with unidirectional non retern valve (3) in the Taper Pipe (2), fixing by the non retern valve end socket (1) that is connected in Taper Pipe (2) inner surface; Aperture grouting stop grouting plug main body (4) external surface suit gum sleeve (5) and metal sleeve (7), the two is provided with metallic gasket (6); Grouting stop grouting plug main body (4) stock inlet (9) end outer surface thread connecting ring is pressed nut (8).
When tightening ring pressure nut, the gum sleeve (5) on the grouting stop grouting plug main body (4) produces distortion by Taper Pipe and expands.
Unidirectional non retern valve (3) is located at the grout outlet place (10) of grouting stop grouting plug main body (4).
Grouting stop grouting plug main body (4) stock inlet (9) end is connected with grout pump by snap joint.
In concrete, hole aperture 14mm, hole depth 12cm.The stop grouting plug grout outlet that will be in the milk inserts in the boring, tightens ring and presses nut.Stock inlet with after grout pump is connected, carries out packer permeability test by snap joint.Pressure reaches 2MPa, and the aperture does not have and leaks.Result of the test shows that the utility model has good aperture only to starch effect, can satisfy distress in concrete chemical grouting requirement.
