Abstract
The utility model discloses a mining steel pipe support filled with concrete, belonging to the mine support system. An arc support is comprised; the arc support is composed of an arc steel pipe and concrete filled within the arc steel pipe; fixed steel plates fixed with the arc support are arranged at two ends of the arc support; pedestals are also comprised; and the two ends of the arc support and the fixed steel plates fixed with the two ends of the arc support are together fixed in the pedestals. The beneficial effects are that the structure is simple; compression strength is large; installation and maintenance are convenient; and usage coat is relatively low.
Description
Technical field
The utility model relates to the mine support system, specifically is a kind of mining steel pipe support of fill concrete.
Background technology
In recent years, because coal resources reduce, exploitation develops into the deep by superficial part gradually.But along with the intensification of mining depth, the pressure that mine bore is increasing, and huge pressure not only may be thrown into the tunnel with the considerable damage coal petrography, destroys roadway support system and surrounding rock structure, and merit threatens to underground work personnel's life.Traditional steel structure support is along with its supporting intensity of increase of the degree of depth does not reach instructions for use.If make the steel structure support chap merely, not only weight is excessive, and cost also increases greatly.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of mining steel pipe support of fill concrete can well solve the problem of present existence.
The utility model is realized with following technical scheme: a kind of mining steel pipe support of fill concrete, comprise arch support, and described arch support is made up of arch steel pipe and the concrete that is filled in the arch steel pipe; At the arch support two ends fixation steel plate that is fixed together with arch support is arranged, also comprise base, the two ends of arch support reach and are fixed in the base with its fixation steel plate that is fixed together.
Add concrete in steel pipe, make concrete that restraint forces arranged, such structure makes outside pressure be born jointly by steel pipe concrete inner with it, and filling effect makes the anti-pressure ability of support be far longer than steel pipe or the independent action effect of coagulation support.
The beneficial effects of the utility model are: simple in structure, have high-strength supporting capacity, and bending rigidity is big, is difficult for torsional deformation, has not only improved bearing capacity but also unlikely cost and has improved.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Among the figure: 1, steel pipe, 2, fixation steel plate, 3, base, 4, concrete.
The specific embodiment
As shown in Figure 1, a kind of arch support of mining steel pipe support of fill concrete is made up of arch steel pipe 1 and the concrete 4 that is filled in the arch steel pipe; At the arch support two ends fixation steel plate 2 that is fixed together with arch support is arranged, also comprise base 3, the two ends of arch support reach and are fixed in the base 3 with its fixation steel plate that is fixed together 2.Have the through hole that cooperates with arch steel pipe 1 on fixation steel plate 2, through hole is passed at the two ends of arch support and fixation steel plate 2 welds together.Base 3 is a concrete bed, and the two ends of arch support are cast in the concrete bed together with fixation steel plate 2.Purpose with fixation steel plate is the stress surface that increases steel pipe and cement base, so that make support more firm.
Concrete preparation method is: the existing arch that tube bending is become to need, with cement pump concrete is injected in the steel pipe, and treat that concrete setting delivers to underworkings after solid.Prop up with temporary support device earlier and be filled with concrete steel pipe support, again fixation steel plate 2 is enclosed within the steel pipe lower end and welds.In with concrete fixation steel plate being cast in then, so complete concrete steel pipe support has just been finished.The steel pipe concrete bracket supporting should be reserved deformation space, and country rock can be out of shape in pressure release.
