Abstract
The utility model relates to a steel pipe concrete support slip casting mouth sealing device, the intensity of effectively having solved the slip casting mouth is low, the sealed problem of easy outer hourglass of concrete and slip casting mouth, there is the slip casting mouth on the steel pipe of circle arc -shaped steel pipe concrete support, convex sleeve pipe suit is in the steel pipe periphery that has slip casting mouth department, have on the convex sleeve pipe with the same hole of slip casting mouth size shape, before the slip casting, remove convex sleeve pipe along the steel pipe, it closes to make hole and slip casting be fond of salty food, after slip casting finishes, remove convex sleeve pipe along the steel pipe, covered by convex sleeve pipe until the slip casting mouth, the punishment of convex sheathed tube both ends do not has the tip to stretch into convex sleeve pipe to carve the body with the arc of steel pipe junction, arc is carved the body and is made convex sleeve pipe combine closely with the steel pipe to be in the same place, the utility model discloses simple structure has mechanical properties such as better intensity, rigidity and stability, and the whole bearing capacity that can ensure seal and the structure of steel pipe concrete support does not receive the influence of slip casting mouth.
Description
Technical field
The utility model relates to a kind of steel pipe concrete bracket grouting port sealing device.
Background technology
Steel pipe concrete bracket is because having that rigidity is large, intensity is high and the advantage such as suitable for surrounding rock distortion can being widely used in the Deformation control of soft-rock tunnel.In the use procedure of steel pipe concrete bracket, need first to install steel tubular structure, and then by grouting port concreting reserved on steel pipe.The existence of grouting port, brings two problems to steel pipe concrete bracket: one, after core concrete builds end, needs to seal grouting port; Its two, the existence of grouting port, by weakening the bearing capacity of steel pipe concrete bracket, is the weak link easily causing support damage inactivation.Therefore a kind of simple grouting port sealing device is badly in need of.
Summary of the invention
For above-mentioned existing problems, the object of the utility model is just to provide a kind of steel pipe concrete bracket grouting port sealing device, and the intensity efficiently solving grouting port is low, and concrete easily leaks outside and the sealing problem of grouting port.
The technical scheme that the utility model solves is, comprise arc-shaped steel tube concrete support, the steel pipe of arc-shaped steel tube concrete support there is grouting port, circular arc casing pipe sleeve is contained in the steel pipe periphery at grouting port place, circular arc sleeve pipe there is the hole identical with grouting port size shape, before slip casting, along steel pipe movement circular arc sleeve pipe, hole and grouting port are overlapped, after slip casting, along steel pipe movement circular arc sleeve pipe, until grouting port is by circular arc sleeve covers, the circular arc that the two ends place of circular arc sleeve pipe has end to put in circular arc sleeve pipe and steel pipe joint respectively carves body, circular arc carves body makes circular arc sleeve pipe and steel pipe be closely linked.
The utility model structure is simple, has the mechanical properties such as good intensity, rigidity and stability, can guarantee that the seal of steel pipe concrete bracket and the total bearing capacity of structure are not subject to the impact of grouting port.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Shown in Fig. 1-Fig. 6, the utility model comprises arc-shaped steel tube concrete support, the steel pipe 4 of arc-shaped steel tube concrete support there is grouting port 1, circular arc sleeve pipe 2 is sleeved on steel pipe 4 periphery at grouting port place, circular arc sleeve pipe there is the hole 5 identical with grouting port size shape, before slip casting, circular arc sleeve pipe is moved along steel pipe 4, hole and grouting port are overlapped, after slip casting, circular arc sleeve pipe is moved along steel pipe 4, until grouting port is by circular arc sleeve covers, the circular arc that the two ends place of circular arc sleeve pipe has end to put in circular arc sleeve pipe and steel pipe 4 joint respectively carves body 3, circular arc carves body makes circular arc sleeve pipe and steel pipe be closely linked.
Described arc-shaped steel tube concrete support is present technology, to be cascaded the annular stent formed, if the patent No. is a kind of retractable steel tube concrete support of 2013200704602 through joint successively by multiple steel pipe that the circular arc of concrete-core column is housed.
Described circular arc sleeve pipe 2 is for bending to curved sleeve pipe.
Described grouting port 1 is placed in the middle part of any one steel pipe on arc-shaped steel tube concrete support.
The length of described circular arc sleeve pipe 2 is less than 1/2 of steel pipe 4 length having grouting port.
Described circular arc is carved body 3 and curved is carved body for bending, and circular arc carves the effect that body plays fixing circular arc sleeve pipe 2.
Service condition of the present utility model is, before arc-shaped steel tube concrete support is installed, first pertusate circular arc sleeve pipe on the cover of the outside of the steel pipe 4 of the arc-shaped steel tube concrete support with grouting port, install arc-shaped steel tube concrete support, before slip casting, make the hole of circular arc sleeve pipe and grouting port overlap, after slip casting, along the steel pipe movement circular arc sleeve pipe of arc-shaped steel tube concrete support, make grouting port completely circular arc sleeve pipe not had pertusate position to cover sealing, then carve body fixed sleeving by circular arc.
During dismounting, circular arc is carved body and take out, lay down the steel pipe that circular arc carves body, circular arc sleeve pipe, arc-shaped steel tube concrete support successively, to reuse, achieve fast dismantling of the present utility model and remove.
The utility model fills pertusate circular arc sleeve pipe in the steel pipe outer cover having grouting port, not only can play airtight grouting port and strengthen the restraint forces that grouting port week ties up steel pipe, also can improve arc-shaped steel tube concrete support and have the stressed of grouting port position, the utility model is a kind of packaged type grouting port sealing device, effectively can stop the concrete intensity leaking outside and supply grouting port, improve the resistance to overturning of component, thus ensure that steel pipe concrete bracket can obtain higher Strength and Dformation ability.
The utility model structure is simply novel, dependable performance, supporting for mining engineering, underground construction and the engineering that manually digs a well provides a kind of device of rapid sealing grouting port, thoroughly solve prior art deficiency, to guarantee that the arc-shaped steel tube concrete support containing grouting port has the mechanical properties such as good intensity, rigidity and stability.
