Description
Technical field
This utility model relates to the prestressing force reinforcement structure after a kind of slight slope sash beam destroys, and is a kind of at original sash beam
The soil-slope of supporting deforms in the case of causing sash beam failure by shear, in order to control the continuation of side slope timely and effectively
Deformation, guarantee side slope and the stability of upper building, connected by former sash beam compartment fill concrete block and anchor cable concrete
Beam quickly process structure.
Technical background
Hydroelectric project is with large-scale slope project, and soil-slope is normally at the elevation of side slope, excavation off-load and slope
Surface frame lattice beam is the support form that soil-slope is conventional.Due to the impact of the factors such as heavy rain, the loading of Po Ding road surface, through top layer frame
The soil-slope that lattice beam processes still is likely to occur creep deformation.When slight slope creep deforms early period of origination, cut exit position at slight slope
Sash beam first failure by shear occur, if not taking treatment measures, may result in slight slope overall collapse.Conventional process side
Method is to excavate sash beam and part slight slope carries out excavating off-load, increases patch slope concrete support if desired, but said method exists
Operational procedure is more, it is relatively big to process quantities, the problems such as traffic requirement limit off-load amount are arranged at slight slope top.Therefore, in order to and
Time, quickly control slope deformation, it is ensured that side slope steady in a long-term, need to find and a kind of can destroy the slight slope sash beam of rapid construction
After supporting construction.
Summary of the invention
Technical problem to be solved in the utility model is: provide the prestressing force reinforcement structure of a kind of slight slope sash beam, energy
Enough when slight slope sash beam generation failure by shear, by cutting concrete backfill and coupling beam, prestress anchorage cable between near exit sash
The layout of structure, is uniformly applied to slight slope by the anchor force of prestress anchorage cable is cut near exit by coupling beam and fill concrete,
Convenient, fast construction, can control the continuation deformation of side slope, it is ensured that side slope steady in a long-term in time.
This utility model solves technical problem and be the technical scheme is that the prestressing force of a kind of slight slope sash beam strengthens knot
Structure, including be arranged on soil-slope domatic on concrete frame lattice beam, be provided with backfill in the sash of described concrete frame lattice beam mixed
Solidifying soil block, described fill concrete block surface pouring reinforcement concrete coupling beam, described reinforced concrete coupling beams is provided with and stretches into institute
State the prestress anchorage cable in soil-slope.By said structure, the slight slope generation creep deformation initial stage is carried out quick supporting, it is ensured that
Side slope and upper building steady in a long-term.
While using technique scheme, this utility model can also use or combine employing further below
Technical scheme:
The surface of described fill concrete block flushes with the surface of described concrete frame lattice beam.
Described fill concrete block be arranged on described concrete frame lattice beam a row or multi-row on.
Described reinforced concrete coupling beams is arranged on the middle part of described fill concrete block, and described prestress anchorage cable (6) is arranged
Centre at described fill concrete block.
Described fill concrete block and the concrete grade of reinforced concrete coupling beams, arrangement of reinforcement and size and prestressed anchor
The tonnage of rope and length, determine according to slight slope character, importance and deformation extent.
Described fill concrete block and reinforced concrete coupling beams are numbered C25, and surface transverse direction and longitudinal direction arrangement of reinforcement is Φ 16@
20cm；Reinforced concrete coupling beams width and height are respectively 60cm and 30cm；Described prestress anchorage cable parameter is 1500KN, L=
30m。
The beneficial effects of the utility model are: this utility model can slight slope is domatic detrusion occurs after, cut at slight slope
Near exit carries out quick prestressed reinforcement, convenient, fast construction, can in time, effectively control the continuation deformation of side slope, it is ensured that
Side slope and upper building steady in a long-term.
Accompanying drawing explanation
Fig. 1 is section layout drawing of the present utility model.
Fig. 2 is site plan of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the present embodiment be a kind of slight slope sash beam destroy after prestressing force reinforcement structure.Because road arrangement needs
Wanting, need to reserve the construction road 2 of one fixed width in soil-slope 1 Po Ding position, slight slope surface uses concrete frame lattice beam 3
Protect.
Being provided with fill concrete block 4 in the sash of described concrete frame lattice beam 3, described fill concrete block 4 surface pours
Reinforced concrete coupling beams 5, described reinforced concrete coupling beams 5 is provided with the prestress anchorage cable 6 stretched in described soil-slope 1.
The surface of described fill concrete block 4 flushes with the surface of described concrete frame lattice beam 3.
Described fill concrete block 4 be arranged on described concrete frame lattice beam 3 a row or multi-row on.
