Abstract
The invention belongs to the field of talus protection and control and provides a talus unloading reinforcement structure for karst depression. The talus unloading reinforcement structure comprises a protective screen, supporting anchor rods and vertical breast boards. The supporting anchor rods are arranged vertically and fixed onto the vertical breast boards, the lower ends of the supporting anchor rods extend to the outer sides of the vertical breast boards, one side of the protective screen is fixed to the upper ends of the vertical breast boards, and anchor nails are fixed onto the protective screen. The problems that existing anchor rod reinforcement methods which can only reinforce talus peripheries are difficult to enable the taluses to form a whole so as to be limited in reinforcement effect while using anti-slide piles for reinforcement can evidently increase engineering investment and construction period input even though reinforcement effects are remarkable are solved.
Description
Technical field
The present invention relates to talus reinforced structure, belong to talus and administer field.
Background technology
Talus refers generally to the accumulation body comprising falling rocks landwaste not of uniform size being positioned at high steep toe place, avalanche slope.Its relevant governing problem is the difficult problem that geotechnical engineering circle faced and paid close attention to always.Owing to lacking relevant authority file and technical support so far both at home and abroad, this problem is still in partly grope, the semiempirical extensive stage.Grow area at karst, especially there is the carbonate rock area of great amount of soluble in Southwestern China portion, strong corrosion often forms large-area karst depression, and mound, surrounding karst peak, depression, sinkhole, cliff, spring are generally all comparatively grown; Lapies, fluid bowl and corrosion broad slit dense distribution; There are karst and underground river distribution in underground, and place periphery often spreads all over Dangerous Rock Body, block stone (talus) layer.And the talus of karst depression and the talus of general significance different, because of under gravity, due to the control of depression landform, it is subject to the effect of lateral restraint and has class granary phenomenon.And usually must carry out excavate and unload to the talus of this form to meet requirement of engineering in the karst depression engineering of reality, it certainly will cause talus stresses re-distribution and produce new geological disaster.Therefore, how by a kind of effective method and measure, while can ensureing the stability under the talus excavate and unload effect of depression, can also effectively prevent rock mass above the talus of depression from producing secondary disaster, be the engineering challenge needing in karst depression engineering to solve.
Summary of the invention
The object of the invention is to: a kind of karst depression talus off-load reinforced structure is provided, usually must carry out excavate and unload to karst depression talus to meet requirement of engineering to solve in actual karst depression engineering, it certainly will cause talus stresses re-distribution and produce the problem of new geological disaster.
The solution of the present invention is as follows: karst depression talus off-load reinforced structure, comprises antislide pile 1, is all fixedly installed breast boards 2 between any two adjacent antislide piles 1, and the pile body top of antislide pile 1 is provided with hat beam 3, and hat beam 3 is equipped with passive protection net 4;
Described hat beam 3 comprises pedestal 31 and column 32, and pedestal 31 is fixedly installed on the upper end of antislide pile 1 or breast boards 2, and the lower end of column 32 is fixedly installed on pedestal 31, and described passive protection net 4 is laid on column 32;
Described reinforcing device also includes anchor line 5 and location holdfast 6, one end of anchor line 5 is fixed on the upper end of column 32, the other end of anchor line 5 is fixed on holdfast 6, after stretching anchor line 5, holdfast 6 is embedded in the talus on the upside of antislide pile 1, for reinforcing for column 32, when preventing Rolling Stone, the upper end of column 32 is due to stressed excessive and collapse.
Described antislide pile 1 is square-section socketed pile.
Any two antislide piles 1 are parallel mutually, and any one antislide pile 1 all parallels with the breast boards 2 be fixed on this antislide pile 1.
Described antislide pile 1 and breast boards 2 are reinforced concrete structure.
The bottom of described breast boards 2 offers the spilled water hole 7 at through breast boards 2 two ends.
Compared with prior art, major advantage is as follows in the present invention:
When excavate and unload is carried out to karst depression talus, described karst depression talus off-load reinforced structure is installed in the upstream of off-load place before excavation, the sliding force of upstream talus is born by antislide pile and breast boards, prevent the upstream talus when off-load from occurring collapsing, avoid the excavation because of downstream talus to cause talus stresses re-distribution, thus produce the problem of new geological disaster;
Effectively can be stopped the landing of upstream Rolling Stone by the passive protection net of Guan Liang and upper laying thereof, when preventing downstream from constructing, upstream Rolling Stone landing causes security incident, eliminates potential safety hazard.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below the present invention is described in further detail,
See figures.1.and.2, the embodiment of the present invention provides karst depression talus off-load reinforced structure, comprising:
Antislide pile 1, antislide pile 1 is square-section socketed pile, breast boards 2 is all fixedly installed between any two adjacent antislide piles 1, breast boards 2 is mainly used in preventing Study on Rock from extruding from the space between antislide pile 1, the bottom of described breast boards 2 offers the spilled water hole 7 at through breast boards 2 two ends, spilled water hole 7 is for discharging talus internal water accumulation, prevent ponding from too much causing antislide pile 1 or breast boards 2 to collapse, described antislide pile 1 and breast boards 2 are reinforced concrete structure, the pile body top of antislide pile 1 is provided with hat beam 3, described hat beam 3 comprises pedestal 31 and column 32, pedestal 31 is fixedly installed on the upper end of antislide pile 1 or breast boards 2, the lower end of column 32 is fixedly installed on pedestal 31, described passive protection net 4(preferred flexible net) be laid on column 32 that (described hat beam 3 also can adopt other braced structuress, such as lower end embeds the bar construction of antislide pile 1 or breast boards 2, passive protection net 4 is laid on and stretches on the bar construction of antislide pile 1 or breast boards 2 outside, realize the passive protection that Rolling Stone tumbles),
Described reinforcing device also includes anchor line 5 and location holdfast 6, one end of anchor line 5 is fixed on the upper end of column 32, the other end of anchor line 5 is fixed on holdfast 6, after stretching anchor line 5, holdfast 6 is embedded in the talus on the upside of antislide pile 1, for reinforcing for column 32, when preventing Rolling Stone, the upper end of column 32 is due to stressed excessive and collapse.
