Abstract

The invention relates to a safety structure of an underground building, in particular to a safety structure of the underground building applied to the field of the underground buildings. The invention provides the safety structure, which is simple, is low in cost, is convenient for construction and can effectively guarantee the safety and the stability of an underground structural member, of the underground building. The safety structure of the underground building comprises a rock body, an anchor rod and a concrete lining, wherein one part of the anchor rod is anchored into the rock body; the concrete lining is arranged around the rock body; a steel bar net is arranged in the concrete lining; one part of the anchor body is exposed from the rock body; the safety structure of the underground building further comprises a safety structural member; one end of the safety structural member is fixedly connected with the anchor rod, and the other end of the safety structural member is connected with the steel bar net. One end of the safety structural member is fixedly connected with the anchor rod, and the other end of the safety structural member is connected with the steel bar net, so that the rock body and the concrete lining are effectively connected to form a whole; the rock body and the concrete lining bear pressure of external water jointly, and the horizontal seismic force of an earthquake on a tower body can be borne.

Description

Underground structure safeguard construction
Technical field
The present invention relates to a kind of underground structure safeguard construction, particularly a kind of underground structure safeguard construction applying field, underground building.
Background technology
Underground structure is large by external water pressure, and water inlet tower body, under horizontal earthquake action, in order to ensure the safety and stablization of works, needs configure a large amount of reinforcing bar or increase works build or increase Concrete label.In Hydraulic and Hydro-Power Engineering as underground power house, tunnel, the lining cutting of surge shaft etc., to side slope, abutment wall with rock contact, tower body, because underground structure is large by external water pressure, water inlet tower body is under horizontal earthquake action, in order to ensure the safety and stablization of works, traditionally, generally take to configure a large amount of reinforcing bar, increase works build, increase Concrete label, set up the modes such as drain hole and solve.When in above-mentioned several solution, unfavorable to construction investment, also there is impact to the duration of engineering simultaneously.Therefore also do not have a kind of structure simple in prior art, cost is low, easy construction, effectively can ensure the underground structure safeguard construction of underground structure safety and stablization.
Summary of the invention
A kind of structure to be solved by this invention is simple, and cost is low, easy construction, effectively can ensure the underground structure safeguard construction of underground structure safety and stablization.
For solving the problems of the technologies described above, the underground structure safeguard construction that the present invention adopts, comprise rock mass, anchor pole, concrete lining, a part for described anchor pole anchors in rock mass, and described concrete lining is arranged on around rock mass, is provided with steel mesh reinforcement in described concrete lining, a part for described anchor pole is exposed outside rock mass, also comprise safety member, described safety member one end is fixedly connected with anchor pole, and the other end is connected with steel mesh reinforcement.
Further, one end of described safety member is welded with anchor pole.
Further, described safety member and anchor pole single-sided welding, and weld length is more than or equal to 10 times of bolt diameter.
Further, described safety member and anchor pole two-sided welding, and weld length is more than or equal to 5 times of bolt diameter.
Further, described safety member is provided with hook formation away from one end of anchor pole, and described safety member is connected with steel mesh reinforcement by hook formation.
Further, the length that described anchor pole exposes outside rock mass is more than or equal to 0.5m.
The invention has the beneficial effects as follows: utilize safety member one end to be fixedly connected with anchor pole, the other end is connected with steel mesh reinforcement, rock mass and concrete lining are effectively connected to form entirety, rely on rock mass shared external water pressure, horizontal earthquake power seismic forces can also be born to tower body.Tradition ensures the mode of underground structure safety and stability relatively, and water inlet tower body is taken measures the mode that ensures that tower body is stable under horizontal earthquake action, all needs to increase very large input, also needs the duration.The basis that increase cost is few arranges component of the present invention, and operation is also extremely simple, can greatly improve underground structure safety and stablization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Component, position and numbering in figure: rock mass 1, anchor pole 2, concrete lining 3, safety member 4, hook formation 5, steel mesh reinforcement 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, underground structure of the present invention safeguard construction, comprise rock mass, anchor pole, concrete lining, a part for described anchor pole anchors in rock mass, and described concrete lining is arranged on around rock mass, is provided with steel mesh reinforcement in described concrete lining, a part for described anchor pole is exposed outside rock mass, also comprise safety member, described safety member one end is fixedly connected with anchor pole, and the other end is connected with steel mesh reinforcement.The good underground structure of wall rock condition, as underground power house, tunnel, the surge shaft of Hydraulic and Hydro-Power Engineering, side slope, and the underground mine having firm rock mass, when excavating country rock or side slope, all can carry out bolt support in time, to ensure the stable of country rock or side slope.Underground power house, tunnel, surge shaft need reinforced concrete lining layer, and side slope needs to paste slope steel concrete.Utilize safety member one end to be fixedly connected with anchor pole, the other end is connected with steel mesh reinforcement, and rock mass and concrete lining are effectively connected to form entirety, relies on rock mass shared external water pressure, can also bear horizontal earthquake power seismic forces to tower body.
One end of described safety member is welded with anchor pole.Adopt the connected mode of welding, simple and reliable, be connected firmly.
As the preferred scheme of one, described safety member and anchor pole single-sided welding, and weld length is more than or equal to 10 times of bolt diameter.Single-sided welding adopts aforesaid weld length to ensure, and anatomical connectivity is firm.
As the preferred scheme of one, described safety member and anchor pole two-sided welding, and weld length is more than or equal to 5 times of bolt diameter.Two-sided welding adopts aforesaid weld length to ensure, and anatomical connectivity is firm.
Described safety member is provided with hook formation away from one end of anchor pole, and described safety member is connected with steel mesh reinforcement by hook formation.Adopt hook formation, can easily and reliably by safety member and steel mesh reinforcement
The length that described anchor pole exposes outside rock mass is more than or equal to 0.5m.Conveniently be connected with safety member, anchor pole exposes outside mentioned length scope.
