Abstract
The utility model relates to a well wall reinforcing device which is suitable for various mine vertical well shafts which need increasing the carrying capacity of well walls. A circular walling crib which is composed of arc steel plates and sectional steel is arranged in the well wall, and an integral anchor rod used for anchoring the circular walling crib is arranged between the circular walling crib and the well wall. The carrying capacity of the well wall can be increased via the common assembly function of the steel plates or the sectional steel and the anchor rod or the individual function of the steel plates, so the carrying capacity of the well wall is increased and the utility model can attain the purpose of preventing and governing well wall breaking accidents. The utility model has the advantages of simple structure, easy manufacture, easy construction, little shaft space occupying and good reinforcing effect.
Description
Technical field
The utility model relates to a kind of borehole wall bracing means, is particularly useful for the various forms of mine vertical shaft pit shafts that needs improve borehole wall supporting capacity.
Background technology
In recent years, the mining areas such as big village, Xuzhou, the Huaibei and Yanzhou of China East China have more than 90 shaft of vertical well that the shaft wall fracture accident takes place in succession.Trace it to its cause and be mostly that so cause shaft wall structure unreasonable, borehole wall supporting capacity is not enough because do not consider the vertical additional force that the borehole wall is produced because peripheral ground sinks when being limited to shaft building.For addressing this problem, at present, the mode that this type of pit shaft of having built is taked to reinforce is channel-section steel to be processed into arc structure connect into annular walling crib, be fixed on the borehole wall by the mode of hanging or pile up, by building or the sprayed mortar formation channel-section steel and the concrete assembly reinforcing borehole wall, improve the bearing capacity of the borehole wall at last with this.But because the annular walling crib rigidity that the channel-section steel segmental arc is connected to form is too little; the concrete strength that sprays or build is too low; cause in this way the borehole wall reinforced through regular meeting because to reinforce the back supporting capacity not enough, improve very little and take shaft section greatly and can not engineering demands.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model provide a kind of rational in infrastructure, take that the pit shaft useful area is little, the big borehole wall bracing means of borehole wall supporting capacity after the easy construction, reinforcing.
The technical scheme that its technical problem that solves the utility model adopts is: the annular walling crib that is surrounded by curved plate or shaped steel is set in the borehole wall, and being provided with its anchoring between the annular walling crib and the borehole wall is holistic anchor pole; Leave the gap of filling concrete or other solid material between the described annular walling crib and the borehole wall; The butt joint of the described annular walling crib that is surrounded by curved plate or shaped steel can be welding, also can be that bolt connects.
The beneficial effects of the utility model are: consolidation effect is good, reinforces back borehole wall supporting capacity height; It is little to take shaft section; Easy construction, workmanship are easy to control.
Description of drawings
Fig. 1 is the utility model borehole wall bracing means structure chart.
Among the figure: 1-annular walling crib, 2-anchor pole, 3-space, the 4-borehole wall.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
A kind of borehole wall bracing means of the utility model, it is formed by annular walling crib 1 with the anchor pole 2 that annular walling crib 1 is fixed on the borehole wall 4, annular walling crib 1 is processed into the arc structure that adapts with the borehole wall 4 internal diameters by steel plate or other shaped steel, with anchor pole 2 annular walling crib 1 is anchored on the borehole wall 4 inner surfaces, the butt joint of annular walling crib 1 can be that to weld also can be that bolt connects; Leave the space 3 of filling concrete or other solid material between walling crib 1 outside and the borehole wall 4 inner surfaces, according to on-site actual situations filling concrete or other solid material in space 3, fastening annular walling crib 1 is connected with the borehole wall 4, compound action by anchor pole 2 and steel plate or shaped steel walling crib 1 improves the supporting capacity of the borehole wall, strengthens consolidation effect.
