Abstract
The invention discloses an internal-bracing well loop. The internal-bracing well loop comprises a well loop formed by splicing of multiple blocks of steel channel. Internal-bracing parts are arranged at the bottom of the well loop and comprise an internal-bracing disc, studs arranged among the internal-bracing disc and the steel channel and fasteners connected to the studs. The studs, four in number, are all distributed into the well loop. The fasteners are metal blocks with threaded holes in middles. The steel channel is spliced by means of keys. A gap is kept at the position where every two steel channel are connected. The internal-bracing well loop has following beneficial effects: the well loop is effectively utilized for top supporting of a well wall in order to prevent the well wall against collapse.
Description
Technical field
The present invention relates to the category of well hole ancillary service, specifically a kind of inner support walling crib.
Background technology
In Mine Production; all can set up pit shaft as the important channel contacting earth's surface and underground; in the process of construction of pit shaft; often meeting with water-bearing stratum, in order to prevent infiltration, need grouting behind shaft or drift lining be carried out; water shutoff material is injected in the gap of and rock stratum outer at the borehole wall; and also need after slip casting to adopt high pressure to enter borehole wall skin to make slurries, now need to utilize walling crib to carry out support to the borehole wall, avoid borehole wall avalanche.
Summary of the invention
The present invention aims to provide a kind of inner support walling crib, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of inner support walling crib, is characterized in that: comprise the walling crib be spliced by polylith channel-section steel, is provided with inner support parts in bottom walling crib; Described inner support parts comprise interior support plate, are arranged on the stud between interior support plate and channel-section steel, the securing member be connected on stud; Described stud is four, is distributed in walling crib; Described securing member is the metal derby that centre has screwed hole; Described channel-section steel is spliced by key, and channel-section steel between two junction leaves certain gap.
Further, described securing member is provided with arcwall face towards channel-section steel one end, and the radian that the radian of arcwall face and channel-section steel bend is adaptive.
Beneficial effect of the present invention is:
One, walling crib adopts polylith channel-section steel key to be spliced, and certain space is left in channel-section steel junction, can make walling crib in hyperbaric environment, bear higher pressure, avoids stress to concentrate.
Two, be provided with inner support parts in bottom walling crib, by being rotatably provided in fasteners tight on stud or screwing out the position controlling securing member, regulate the stressed degree of each channel-section steel, avoid channel-section steel to produce deformation and scrap.
Accompanying drawing explanation
Fig. 1 is inner support walling crib structural representation provided by the invention.
Mark in figure: 1 be channel-section steel, 2 be interior support plate, 3 be securing member, 4 be stud, 5 be key, 6 for arcwall face.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of inner support walling crib, comprises the walling crib be spliced by polylith channel-section steel 1, is provided with inner support parts in bottom walling crib; Described inner support parts comprise interior support plate 2, are arranged on the stud 4 between interior support plate 2 and channel-section steel 1, the securing member 3 be connected on stud 4; Described stud 4 is four, is distributed in walling crib; Described securing member 3 is the middle metal derby having screwed hole; Described channel-section steel 1 is spliced by key, and channel-section steel between two junction leaves certain gap.Described securing member 3 is provided with arcwall face 6 towards channel-section steel one end, and the radian that the radian of arcwall face 6 and channel-section steel bend is adaptive.
In use, can move between stud 4 by regulating securing member 3, when the intensity of pressure is little, securing member 3 can be loosened, but when the intensity of pressure is larger, walling crib is needed to support the borehole wall, now, can also according to demand, some or several securing member 3 be regulated to be adjacent to channel-section steel 1, and the effect avoiding stress to concentrate can be played in channel-section steel 1 gap that junction is left between two, avoid channel-section steel deformation.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
