Abstract
The utility model discloses an underground factory building rock anchor beam reinforced structure belongs to hydraulic and hydroelectric engineering technical field, including rock mass and rock anchor beam, the rock anchor beam is located the tiltboard terrace of rock mass, is equipped with a plurality of mortar stocks between rock anchor beam and the rock mass, pre -buried in the rock anchor beam have a plurality of pre buried pipeline, pre buried pipeline runs through the rock anchor beam and meets with the rock mass. When the loss of anchor power appeared in the anchor stock of rock anchor beam, this technical scheme can keep under the unchangeable circumstances of rock anchor beam primary structure, punched to the rock mass that the pipeline connect through pre buried pipeline, and the new stock of increase is reinforced between rock mass and rock anchor beam, this reinforced structure construction degree of difficulty is less, consolidates effectually, and the hole shaping is convenient, and construction cost is lower, has ensured the safety and stability operation of rock anchor beam and the monolithic stability of rock anchor beam periphery rock mass.
Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering technical field, relates to a kind of reinforcement measure of underground power house rock anchorage beam advance reservation, specifically relates to a kind of underground power house rock anchorage beam ruggedized construction.
Background technology
In hydraulic structure, underground power house generally adopts rock anchorage beam as the operating structure of bridge machine.Rock anchorage beam is as its name suggests and adopts grouting rock bolt to be anchored at by beam on the rock mass with skew wall, makes beam keep stable by the anchoring between anchor pole and rock mass and the frictional force between rock anchorage beam and crag.
Existing rock anchorage beam is not reserved logistics measure generally, only adopts grouting rock bolt as anchoring beam, once loss appears in the anchored force of rock anchorage beam, repair the cost just needing cost very high, even be difficult to repair, this will cause extreme loss to engineering, bring very large potential safety hazard simultaneously.
Utility model content
In order to solve the problem, the utility model provides a kind of underground power house rock anchorage beam ruggedized construction, when rock anchorage beam occurs loss due to the anchored force of grouting rock bolt, by simple and construct comparatively efficiently, realize the reinforcing of rock anchorage beam and guarantee the resistance to overturning of rock anchorage beam periphery rock mass.
The utility model is achieved by following technical solution.
A kind of underground power house rock anchorage beam ruggedized construction, comprise rock mass and rock anchorage beam, described rock anchorage beam is positioned at the tilting table terrace of rock mass, is provided with some grouting rock bolts between rock anchorage beam and rock mass, be embedded with some pre-buried pipelines in described rock anchorage beam, described pre-buried pipeline runs through rock anchorage beam and connects with rock mass.
Further, described pre-buried pipeline is between two laterally adjacent grouting rock bolts.
Further, described pre-buried pipeline is the decorative pattern steel pipe of atresia.
Further, the caliber of described pre-buried pipeline is 60 ~ 80mm.
The beneficial effects of the utility model are:
A kind of underground power house rock anchorage beam ruggedized construction described in the utility model, the later stage is used at rock anchorage beam, when there is anchoring load losses in the anchoring rod of rock anchorage beam, when keeping rock anchorage beam original structure constant, by pre-buried pipeline, the rock mass that pipeline connects is punched, between rock mass and rock anchorage beam, increase new anchor pole reinforce; This ruggedized construction difficulty of construction is less, and consolidation effect is good, hole convenient formation, and construction cost is lower, ensure that the safe and stable operation of rock anchorage beam and the monolithic stability of rock anchorage beam periphery rock mass, has broad application prospects.
Accompanying drawing explanation
Fig. 1 is A cross section structure schematic diagram of the present utility model;
Fig. 2 is B cross section structure schematic diagram of the present utility model;
Fig. 3 is by structural representation that pre-buried pipeline is holed in the utility model.
In figure: 1-rock mass, 2-rock anchorage beam, the pre-buried pipeline of 3-, 4-grouting rock bolt, 5-reinforced hole.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, a kind of underground power house rock anchorage beam ruggedized construction described in the utility model, comprise rock mass 1 and rock anchorage beam 2, described rock anchorage beam 2 is positioned at the tilting table terrace of rock mass 1, some grouting rock bolts 4 are provided with between rock anchorage beam 2 and rock mass 1, be embedded with some pre-buried pipelines 3 in described rock anchorage beam 2, described pre-buried pipeline 3 runs through rock anchorage beam 2 and connects with rock mass 1; When anchoring load losses appears in the grouting rock bolt 4 of fixing rock anchorage beam 2, namely carry out drilling construction by 3 pairs, built-in pipe road rock mass 1, new anchor pole is set in this boring, realizes the reinforcing to rock anchorage beam 2.
Embodiment
Along with the increase of load-bearing time, may there is anchoring load losses and even lose anchored force in the mortar anchor pole 4 of rock anchorage beam 2 on rock mass 1.
Therefore need carry out in accordance with the following steps when rock anchorage beam 2 is built:
First, according to the layout pattern of rock anchorage beam 2 grouting rock bolt 4, determine position and the spacing of pre-buried pipeline 3; After completing the reinforcing bar binding of rock anchorage beam 2, in rock anchorage beam 2, pre-buried pipeline 3 is installed, pre-buried pipeline 3 is cast in the concrete of rock anchorage beam 2; Treat rock anchorage beam 2 concrete setting, remove assembling reinforcement.
As shown in Figure 3, when connecting the grouting rock bolt 4 of rock anchorage beam 2 with rock mass 1 and occurring anchoring load losses, by pre-buried pipeline 3 pairs of rock body drilled, when rock anchorage beam 2 does not bear crane load, in the reinforced hole 5 that rock mass 1 newly bores, new anchor pole is installed and slip casting.
Described embedded steel tube 3 is the decorative pattern steel pipe of atresia, caliber is 60 ~ 80mm, between two laterally adjacent grouting rock bolts 4, embedded steel tube 3 well can be combined with rock anchorage beam 2, and the anchor pole that the later stage increases newly after bored grouting on rock mass 1 also can be combined closely with rock anchorage beam 2.
Holed by pre-buried pipeline 3 pairs of rock mass 15 mode, rock anchorage beam 2 can be avoided to be subject to the destruction of rig, to ensure the monolithic stability of rock anchorage beam periphery rock mass.
