Description
Technical field
The present invention relates to a kind of steel pipe concrete bracket slip casting mouth sealing devices.
Background technique
Steel pipe concrete bracket because have many advantages, such as that rigidity is big, intensity is high and can adapt to surrouding rock deformation be widely used in it is soft
The Deformation control in rock gangway road.In the use process of steel pipe concrete bracket, needs first to install steel-tube construction, then pass through steel again
The grouting port casting concrete reserved on pipe.The presence of grouting port brings two problems to steel pipe concrete bracket：First,
After core concrete pours end, need to be sealed grouting port；Second, the presence of grouting port is mixed steel pipe is weakened
The bearing capacity of solidifying soil bracket, is the weak link for easily causing bracket damage inactivation.Therefore it is badly in need of a kind of simple and easy slip casting
Mouth sealing device.
Summary of the invention
For above-mentioned there are problem, the purpose of the present invention is just to provide a kind of steel pipe concrete bracket grouting port sealing dress
It sets, the intensity for efficiently solving grouting port is low, and concrete is easy the sealing problem of leakage and grouting port.
The technical solution that the present invention solves is, including arc-shaped steel tube concrete support, arc-shaped steel tube concrete support
Steel pipe on have grouting port, arc-shaped casing is sleeved on the steel pipe periphery at grouting port, has on arc-shaped casing and grouting port
Size shape identical hole before slip casting, along the arc-shaped casing of steel pipe movement, is overlapped hole and grouting port, slip casting is complete
Bi Hou, along the arc-shaped casing of steel pipe movement, until grouting port by arc-shaped sleeve covers, has respectively at the both ends of arc-shaped casing
End puts in arc-shaped casing and the arc-shaped of steel pipe joint carves body, and arc-shaped body of carving ties arc-shaped casing and steel pipe closely
It is combined.
The configuration of the present invention is simple has the mechanical properties such as preferable intensity, rigidity and stability, it can be ensured that concrete filled steel tube
The airtightness of bracket and the total bearing capacity of structure are not influenced by grouting port.

Specific embodiment
It elaborates below in conjunction with attached drawing to a specific embodiment of the invention.
As shown in Fig. 1-Fig. 6, the present invention includes arc-shaped steel tube concrete support, the steel of arc-shaped steel tube concrete support
There is grouting port 1 on pipe 4, arc-shaped casing 2 is sleeved on 4 periphery of steel pipe at grouting port, has on arc-shaped casing and grouting port
Size shape identical hole 5 before slip casting, moves arc-shaped casing along steel pipe 4, is overlapped hole and grouting port, slip casting
After, arc-shaped casing is moved along steel pipe 4, until grouting port, by arc-shaped sleeve covers, the both ends of arc-shaped casing are punished
There is not end to put in arc-shaped casing and carve body 3 with the arc-shaped of 4 joint of steel pipe, arc-shaped body of carving makes arc-shaped casing and steel pipe
It is closely linked.
The arc-shaped steel tube concrete support is present technology, is by multiple arc-shaped equipped with concrete-core column
Steel pipe is successively cascaded the annular stent of composition through connector, and one kind such as Patent No. 2013200704602 is telescopic
Steel pipe concrete bracket.
The arc-shaped casing 2 is to bend to arc-shaped casing.
The grouting port 1 is placed in the middle part of any one steel pipe on arc-shaped steel tube concrete support.
The length of the arc-shaped casing 2 is less than the 1/2 of 4 length of steel pipe for having grouting port.
The arc-shaped body 3 of carving is to be bent arc-shaped body of carving, the arc-shaped work carved body and play fixed arc-shaped casing 2
With.
Service condition of the invention is, before the installation of arc-shaped steel tube concrete support, first in the circular arc for having grouting port
The outside of the steel pipe 4 of shape steel pipe concrete bracket puts on the arc-shaped casing of hole, installs arc-shaped steel tube concrete branch
Frame is overlapped the hole of arc-shaped casing and grouting port before slip casting, after slip casting, along arc-shaped steel tube concrete support
The arc-shaped casing of steel pipe movement, so that grouting port is not had hole on arc-shaped casing completely position covering sealing, then with justify
Arc carves body fixed sleeving.
When dismounting, arc-shaped body of carving is taken out, successively lays down and arc-shaped carves body, arc-shaped casing, arc-shaped steel tube coagulation
The steel pipe of native bracket realizes quick dismounting of the invention to reuse.
The present invention is equipped with the arc-shaped casing of hole in the steel pipe outer cover for being provided with grouting port, can not only play closed slip casting
Mouthful and reinforce grouting port week dimension steel pipe restraining force, can also improve arc-shaped steel tube concrete support have at grouting port position by
Power, the present invention are a kind of packaged type slip casting mouth sealing devices, can effectively prevent the leakage of concrete and supply the strong of grouting port
Degree, improves the overall stability of component, to ensure that steel pipe concrete bracket can obtain higher intensity and deformability.
The configuration of the present invention is simple is novel, reliable performance, and the supporting for mining engineering, underground engineering and the artificial engineering that digs a well mentions
The device for having supplied a kind of rapid sealing grouting port solves prior art deficiency, thoroughly to ensure the arc-shaped steel containing grouting port
Pipe concrete bracket has the mechanical properties such as preferable intensity, rigidity and stability.
