Abstract
The grouting pipe includes one pipe with grouting passage, one mortar discharging casing connected to the pipe, one non-return valve with valve clacks possessing mortar discharging ports and set inside the mortar discharging casing, and mortar inlet passage connected to the mortar inlet. After concrete enters to the inner cavity of the non-return valve clacks, the mortar discharging ports are opened with the extrusion of concrete for outflow of concrete while the back flowing concrete is blocked with the extruded and closed mortar discharging ports.
Description
Technical field
The present invention relates to a kind of grout pipe that is used for the concrete placing that constructing tunnel uses.
Background technology
Grout pipe is to precoat to be located in the concrete slab of arch.And in constructing tunnel, because it is gapped between the concrete slab of arch and the tunnel wall, therefore need fill up this gap with concrete, present grout pipe comprises body, the inner chamber of body is a slurry intake channel, and concrete is then discharged from the outlet of body and flow in the described gap when grouting in body.But existing grout pipe is in the grouting operation process, and concrete still can reflux in the outlet of body, causes trouble to construction, also easily causes construction quality to reduce.
Summary of the invention
The object of the invention provides a kind of grout pipe, and it can prevent that when grouting operation concrete from refluxing from its body.
Technical scheme of the present invention is: a kind of grout pipe, comprise body with slurry intake channel, the export department of described body is fixedly connected with the pulp conduit, is provided with one way valve in the described pulp conduit, and described one way valve comprises at least two involutory clappers.
Described one way valve has stock inlet, and described stock inlet is connected with described slurry intake channel, forms slot-shaped slurry spitting port between described each clapper.
Also have crackle on the described clapper, described crackle is positioned at the middle part of clapper.
Be fixed with the baffle plate that radially extends on the described pulp conduit or on the described body along body.
Has external screw thread on the external surface of described body.
Has axially extended reinforcing rib on the external surface of described body along body.
The inlet portion of described body is connected with inlet cover, has internal thread on the inner surface of described body, described inlet cover by with body on internal thread threaded engagement and being connected mutually with body.
Described pulp conduit flare.
The present invention compared with prior art, have following advantage: concrete flows in the inner chamber of one way valve from stock inlet after entering the slurry intake channel of body again, because concrete pressure effect, make the slurry spitting port on the clapper open, concrete promptly outwards flows out from open slurry spitting port, and concrete is when refluxing, be subjected to concrete reverse squeezing action to make slurry spitting port closure on the clapper again, thereby can prevent that concrete from refluxing from body, so that the work progress of tunnel construction grouting is convenient.
Description of drawings
Accompanying drawing 1 is a front view of the present invention;
Accompanying drawing 2 is the enlarged drawing of overlooking of the present invention;
Accompanying drawing 3 takes off main sectional view after the inlet cover for the present invention;
Wherein: wherein: 1, pulp conduit; 2, baffle plate; 3, body; 4, external screw thread; 5, reinforcing rib; 6, inlet cover; 7, clapper; 8, slurry spitting port; 9, crackle; 10, slurry intake channel; 11, internal thread; 12, stock inlet; 13, one way valve;
The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 3, a kind of grout pipe, comprise body 3 with slurry intake channel 10, the inlet portion of described body 3 is connected with inlet cover 6, have internal thread 11 on the inner surface of described body 3, described inlet cover 6 by with body 3 on internal thread 11 threaded engagement and being connected mutually with body 3.The export department of described body 3 is fixedly connected with pulp conduit 1, be provided with one way valve 13 in the described pulp conduit 1, described one way valve 13 comprises at least two involutory clappers 7, described one way valve 13 has stock inlet 12, described stock inlet 12 is connected with slurry intake channel 10, is combined to form the slurry spitting port 8 that is slot-shaped between the described clapper 7.
Referring to accompanying drawing 3, also have crackle 9 on the described clapper 7, described crackle 9 is positioned at the middle part of clapper 7, in accompanying drawing 2, described crackle 9 and slurry spitting port 8 formation " ten " font that intersects.
This grout pipe is in application process, the inlet cover 6 of outwarding winding, concrete enters in the slurry intake channel 10 from the inlet portion of body 3, enter in the inner chamber of one way valve 13 from stock inlet 12 then, because the concrete pressure effect of fluid, make the slurry spitting port 8 between the clapper 7 open, concrete just flows into the pulp conduit 1 from slurry spitting port 8.In the embodiment shown in accompanying drawing 1, the accompanying drawing 3, described pulp conduit 1 flare, when concrete flows out in pulp conduit 1, enter in the space between tunnel wall and the concrete slab building with promptly being divergent shape, and the concrete flow in flowing into slurry intake channel 10 is greatly the time, thereby the crackle 9 on the clapper 7 promptly splits automatically and strengthened the pulp flow of slurry spitting port 8.If concrete refluxes in pulp conduit 1, because concrete buffer brake effect, the slurry spitting port 8 of one way valve 13 is promptly closed, makes concrete oppositely to enter in the one way valve 13, thereby can prevent that concrete from refluxing from body 3.For prevent that this grout pipe from axially sliding in the concrete that solidifies, described pulp conduit 1 is provided with baffle plate 2, also has external screw thread 4 on the external surface of described body 3, on the external surface of body 3, has simultaneously reinforcing rib 5, both can strengthen the axial bearing capacity of external screw thread 4, can strengthen the rigidity of body 3 again, external screw thread 4 can also play the effect of the bonding strength that strengthens body 3 and arch sheet.
