Abstract
The utility model belongs to the technical field of injection pipes, and discloses a high-strength injection pipe. The high-strength injection pipe is mainly technically characterized by comprising a metal framework layer located on the inner side of the injection pipe and a braided fabric layer located on the outer side of the injection pipe, and a filter screen layer is disposed between the metal framework layer and the braided fabric layer. As a further improvement, the filter screen layer is a braided nylon screen with 300 to 400 meshes or a metal screen, and the metal framework layer is a circular or square spiral metal framework. Grout easily passes through the injection pipe and can be squeezed out on conditions of low pressure during injection. In addition, the high-strength injection pipe is not easy to be broken during a uniform injection process, increases corrosion resistance, prolongs service life, increases strength and is easy in construction and installation.
Description
Technical field
The utility model belongs to the Grouting Pipe technical field, relates in particular to a kind of high strength Grouting Pipe.
Background technology
The Grouting Pipe of using roughly comprises two kinds at present, hard Grouting Pipe and soft Grouting Pipe, and hard Grouting Pipe grouting pressure is big, and construction inconvenience and slip casting are inhomogeneous; Though and soft Grouting Pipe easy construction is yielding, slip casting is inhomogeneous, grouting pressure greatly, cause fracture easily in the slip casting process.
The utility model content
Problem to be solved in the utility model just provide a kind of easy construction, not yielding, grouting pressure is little, slip casting is even, the high strength Grouting Pipe that is difficult for breaking in the slip casting process.
For addressing the above problem, the technical solution adopted in the utility model is: comprise being positioned at the braid layer that inboard metallic framework layer is positioned at the outside, be provided with the filtration stratum reticulare between described metallic framework layer and braid layer.
Its additional technical feature is:
Described filtration stratum reticulare is woven nylon net or wire lath;
Described woven nylon net or wire lath are 300-400 order net sheet;
Described metallic framework layer is circular or square spiral metal skeleton.
High strength Grouting Pipe provided by the utility model compared with prior art, have the following advantages: one, owing to comprise and be positioned at the braid layer that inboard metallic framework layer is positioned at the outside, between described metallic framework layer and braid layer, be provided with the filtration stratum reticulare, make slurries be easy to by, when slip casting, just slurries can be extruded under the little situation of required pressure, and slip casting evenly, be difficult for breaking in the slip casting process; Its two because described filtration stratum reticulare is woven nylon net or wire lath, not only slip casting is even, and has improved its decay resistance, has prolonged its application life; Its three because described metallic framework layer be circular or square spiral metal skeleton, improved its intensity, make Grouting Pipe not yielding, be easy to construction and installation.
Description of drawings
Fig. 1 is the structural representation of the utility model high strength Grouting Pipe;
Fig. 2 is a high strength Grouting Pipe cross-sectional view shown in Figure 1;
Fig. 3 is the structural representation of screen pack.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model high strength Grouting Pipe.
Shown in Figure 2 as Fig. 1, the utility model high strength Grouting Pipe comprises being positioned at the braid layer 3 that inboard metallic framework layer 1 is positioned at the outside, is provided with between metallic framework layer 1 and braid layer 3 and filters stratum reticulare 2.Make slurries be easy to by, when slip casting, just slurries can be extruded under the little situation of required pressure, and, in slip casting evenly, be difficult for breaking in the slip casting process; Its two because described filtration stratum reticulare is woven nylon net or wire lath, not only slip casting is even, and has improved its decay resistance, has prolonged its application life.
Filtration stratum reticulare 2 is preferably woven nylon net or wire lath as shown in Figure 3, and this filtration stratum reticulare 2 is formed by organizine 21 and tram 22 braidings, and not only slip casting is even, and has improved its decay resistance, has prolonged its application life.Certainly, except nylon wire or wire lath, filter stratum reticulare 2 and also can make by other material.
Woven nylon net or wire lath are preferably 300-400 order net sheet, like this, make slurries pass through easily.
In order to improve the intensity of Grouting Pipe, metallic framework layer 1 is designed to the round screw thread metallic framework, like this, improved its intensity, make Grouting Pipe not yielding, be easy to construction and installation.Certainly, metallic framework layer 1 also can be designed as the square spiral metallic framework.
Certainly, the utility model high strength Grouting Pipe not only is confined to above embodiment, as long as adopt the high strength Grouting Pipe of said structure, all falls into the scope of the utility model high strength Grouting Pipe protection.
Claims (4)
1. the high strength Grouting Pipe comprises being positioned at the braid layer that inboard metallic framework layer is positioned at the outside, it is characterized in that: be provided with the filtration stratum reticulare between described metallic framework layer and braid layer.
2. high strength Grouting Pipe according to claim 1 is characterized in that: described filtration stratum reticulare is woven nylon net or wire lath.
3. high strength Grouting Pipe according to claim 1 and 2 is characterized in that: described woven nylon net or wire lath are 300-400 order net sheet.
