Abstract
The invention relates to a grouting port sealing device for a concrete-filled steel tube support and effectively solves the problem that concrete is prone to leakage due to low strength of the grouting port and the problem about sealing of a grouting port. The grouting port sealing device is characterized in that the grouting port is formed in any steel tube of the circular-arc-shaped concrete-filled steel tube support, the steel tube located at the grouting port is sleeved with a circular-arc-shaped casing, and a hole having the same size and the same shape with the grouting port is formed in the circular-arc-shaped casing; before grouting, the circular-arc-shaped casing is moved along the steel tube, and the hole coincides with the grouting port; after grouting, the circular-arc-shaped casing is moved along the steel tube until the grouting port is covered with the circular-arc-shaped casing, circular-arc-shaped wedge bodies with end parts extending into the position where the circular-arc-shaped casing and the steel tube are connected are arranged at two ends of the circular-arc-shaped casing respectively, and the circular-arc-shaped casing and the steel tub are tightly combined by the aid of the circular-arc-shaped wedge bodies. The grouting port sealing device for the concrete-filled steel tube support is simple in structure, has better mechanical properties such as strength, rigidity, stability and the like, and can guarantee that the leakproofness of the concrete-filled steel tube support and the overall bearing capacity of the structure are not influenced by the grouting port.
Description
Technical field
The present invention 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 present invention 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 present invention 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.
Structure of the present invention 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, the specific embodiment of the present invention is elaborated.
Shown in Fig. 1-Fig. 6, the present invention includes 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 invention 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 invention and remove.
The present invention 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 present invention 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.
Structure of the present invention 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.
