Abstract
A grouting construction apparatus comprises a slurry inlet pipe, a slurry return pipe, an outer pipe, a slurry ejection pipe and a pressure gauge, wherein the slurry inlet pipe and the outer pipe are connected through electric welding, the tail end of the slurry inlet pipe is connected to the slurry ejection pipe, the slurry return pipe and the outer pipe or the slurry inlet pipe are connected through electric welding, the pressure gauge is installed on the slurry return pipe, and the diameter of a grouting hole matches with that of the outer pipe, and a slurry preventing ring is plugged between the outer pipe and the grouting hole. The grouting construction apparatus is simple, practical, safe, reliable and economical and is easy for realization, manufacture, installation and operation. Moreover, the grouting construction apparatus lowers the material consumption.
Description
Technical field
The utility model relates to a kind of engineering construction device, particularly a kind of grouting construction device.
Background technology
In various infrastructures, need owing to build, in engineering, be provided with various caverns, the hole wall of these caverns is taked concrete or reinforced concrete lining layer substantially, no matter take the lining cutting of which kind of type, all have condensing coming to nothing in various degree, backfill grouting mainly is to tamp these spaces of coming to nothing; Secondly, concrete defect and country rock surface split to fall into carry out reinforcement, thereby make hole inner concrete lining cutting or fill concrete connect into an integral body with country rock securely, to guarantee the safe operation of base fixed and cavern.
Building foundation rock mass and surrounding rock of chamber are the geology defective of basement rock and the rock mass defective that the construction blasting off-load causes in the purpose that certain depth carries out consolidation grouting, to recover and to improve globality, uniformity and the impervious ability of its basement rock, improve basic supporting capacity.
Backfill grouting and consolidation grouting are widely used in all kinds of caverns to be handled, consolidation grouting common use in handle the building foundation.The grouting construction apparatus structure is comparatively complicated at present, installs and use inconvenience.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easy to process, and is flexible for installation, uses simple grouting construction device.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: a kind of grouting construction device, comprise inlet pipe, inlet pipe is fixedlyed connected with outer tube, return pipe and outer tube or with inlet pipe welding, the inlet pipe afterbody connects Grout-jetting pipe.
Be provided with pressure meter at return pipe.
Between outer tube and grout hole, be provided with anti-slurry ring.
Described outer length of tube part in grout hole adapts with lining concrete, suitably exposes concrete; Outer tube exposes lining concrete and partly takes closing form.
Described outer tube is diameter 42.3 mm, and wall thickness is the common welded tube of 3.25mm.
Described inlet pipe and return pipe are diameter 26.8 mm, and wall thickness is the common welded tube of 2.75mm.
Described Grout-jetting pipe is diameter 32 mm, and wall thickness is the plastic conduit of 1.5mm.
The grouting construction device that the utility model provides, making, installation, easy to operation, safe and reliable, reduced material consumption simultaneously, economic and practical.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of grouting construction device comprises inlet pipe 3, and inlet pipe 3 is fixedlyed connected with outer tube 2, and return pipe 4 welds with outer tube 2 or with inlet pipe 3, if namely take hole internal-circulation type grouting, return pipe 4 is from outer tube 2 otch and welding with it; If take aperture circulation inserted grouting, return pipe 4 is taked 8 shutoff of anti-slurry ring from inlet pipe 3 otch and welding with it between outer tube 2 and the grout hole 7, outer tube 2 length grout hole 7 in partly substantially and lining concrete 1 adapt, suitably expose concrete 1; Outer tube 2 exposes lining concrete 1 part and takes closing form.Grout hole 7 diameters and outer tube 2 diameters are complementary.Inlet pipe 3 afterbodys connect Grout-jetting pipe 6.Be provided with pressure meter 5 at return pipe 4.
An example of making of the present utility model: outer tube 2 is diameter 42.3 mm, and wall thickness is the common welded tube of 3.25mm; Inlet pipe 3 and return pipe 4 are diameter 26.8 mm, and wall thickness is the common welded tube of 2.75mm; Grout-jetting pipe 6 is diameter 32 mm, and wall thickness is the plastic conduit of 1.5mm.
The course of work of the present utility model is as follows: slurries enter from inlet pipe 3, flow into grout hole 7 through Grout-jetting pipe 6, by annular gap between outer tube 2 and the inlet pipe 3, flow out from return pipe 4 at last.
