Description
Technical field
The utility model relates to the excavation reinforcement protection structure that bulk solid is piled up sloping cutting excavation ruggedized construction, particularly fine grained bulk solid such as sand-sliding slope cutting.
Background technology
Western China particularly Sichuan-Tibet highway be distributed with a large amount of bulk solid along the line and pile up the slope, as sand-sliding slope, when the highway construction of building railway engineering particularly, owing to be subjected to the control of conditions such as line style and longitudinal gradient, the bulk solid that some can occur is piled up sloping cutting engineering, owing to the bulk solid deposit that resembles the sand-sliding slope class has shot, domatic source is measured greatly, is difficult to excavation and propped up the characteristics such as protecting difficulty of keeping off, when the road engineering was passed through with the cutting form, a kind of bulk solid of active demand was piled up sloping cutting excavation reinforcement protection structure.
The utility model content
Technical problem to be solved in the utility model provides a kind of bulk solid and piles up sloping cutting excavation reinforcement protection structure, pile up the slope because of excavation and slope reinforcement protection difficult problem that cutting excavation causes to solve bulk solid, effectively guarantee to excavate the stable of cutting engineering.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Bulk solid of the present utility model is piled up sloping cutting excavation reinforcement protection structure, it is characterized in that it comprises: the steel bar concrete reinforcement stake is arranged at excavation cutting toe along circuit longitudinal separation; The steel concrete breast boards is arranged between the adjacent two steel bar concrete reinforcement stakes; Composite drainage network, be arranged at the steel concrete breast boards after; Slip casting spray of molten steel pipe is arranged at intervals between uphill side, descending side and the stake of steel bar concrete reinforcement stake, by slip casting and the grouting and reinforcing of bulk solid formation on every side body.
The beneficial effects of the utility model are, solve bulk solid effectively and piled up the slope reinforcement protection difficult problem that the slope causes because of cutting excavation, simple in structure, easy construction, can guarantee effectively that bulk solid piles up stable behind safety in the sloping digging process and the excavation, have wide popularizing application prospect.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the schematic cross-sectional view that the utility model bulk solid is piled up sloping cutting excavation reinforcement protection structure;
Fig. 2 is the floor map that the utility model bulk solid is piled up sloping cutting excavation reinforcement protection structure.
Member shown in the figure, toponym and corresponding mark: steel bar concrete reinforcement stake 10, steel concrete breast boards 20, composite drainage network 21, slip casting spray of molten steel pipe 30, stablize that rock-soil layer A, bulk solid pile up sloping body B, bulk solid is piled up sloping body direction C.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, bulk solid of the present utility model is piled up sloping cutting excavation reinforcement protection structure, it is characterized in that it comprises: steel bar concrete reinforcement stake 10 is arranged at excavation cutting toe along circuit longitudinal separation; Steel concrete breast boards 20 is arranged between the adjacent two steel bar concrete reinforcement stakes 10; Composite drainage network 21, be arranged at steel concrete breast boards 20 after; Slip casting spray of molten steel pipe 3 is arranged at intervals between uphill side, descending side and the stake of steel bar concrete reinforcement stake 10, by slip casting and the grouting and reinforcing of bulk solid formation on every side body.
The utility model utilizes steel bar concrete reinforcement stake 10 to bear soil pressure and sliding force that bulk solid is piled up sloping cutting top bulk solid, utilize block bulk solid between 10 of steel bar concrete reinforcement stakes of breast boards 20, utilize composite drainage network 21 rows, and prevent that breast boards 20 back bulk solids from being taken out of by underground infiltration and phenomenon occurs emptying, utilize 30 pairs of bulk solids of slip casting spray of molten steel pipe to carry out grouting and reinforcing and form the grouting and reinforcing body, guarantee stablizing in steel bar concrete reinforcement stake 10 digging processs, avoid occurring in the work progress hole that collapses.This structure has solved the slope reinforcement protection difficult problem that bulk solid is piled up sloping cutting excavation difficulty and therefore caused effectively, simple in structure, easy construction, can guarantee effectively that bulk solid piles up stable behind safety in the sloping digging process and the excavation, have wide popularizing application prospect.
The grouting and reinforcing body that described slip casting spray of molten steel pipe 30 slip castings form should be connected to form integral body, usually should be greater than 5m at the uphill side grouting and reinforcing body width of steel bar concrete reinforcement stake 10, and the descending side should be greater than 2m, and reinforcement depth is piled up the degree of depth greater than bulk solid.
Described steel bar concrete reinforcement stake 10 bottoms are embedded in stablizes under the bulk solid in the rock-soil layer, and pile spacing usually should be less than 6m.Steel concrete breast boards 20 should adopt reinforced concrete prefabricated construction, connects by the embedded bar that is arranged in the steel bar concrete reinforcement stake 10, and the lap width of its two ends and steel bar concrete reinforcement stake 10 is not less than 30cm.
Steel bar concrete reinforcement stake 10 should be adopted every 2 piles job-hopping excavation, excavation stake well arranges a joint fore shaft or retaining wall carries out a well protection and at steel concrete breast boards 20 the pre-buried connecting reinforcement in position is set every 1m, should strengthen the observation of bulk solid slope deforming in the digging process and carry out the emergent precautionary measures.Steel bar concrete reinforcement stake 10 construction finish reach design strength 80% after can excavate preceding a ground body, the each cutting depth of ground body should not be greater than 2m before the stake, the timely construction reinforced bar concrete breast boards 20 of palpus behind the excavation.
The above the utility model bulk solid that just explains through diagrams is piled up some principles of sloping cutting excavation reinforcement protection structure, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
