The utility model discloses an adopt multilayer steel reinforcement gabion to stack the combination and form holistic stairstepping dam body, its size is unanimous basically with the gravity dam formula size of conventional concrete, stone masonry block sediment dam etc., not only stable in structure, and self possesses certain "flexibility" characteristic moreover, can effectively adapt to the deformation feedback to the overburden soft foundation of general degree, and do not destroy the dam body, so it is low to building dam foundation requirement, can directly establish on the overburden soft foundation, the construction is simple, the cost is low.
Description
Technical field
The utility model relates to a kind of flexible blocking slag dam structure, belongs to water conservancy, water power, engineering construction technology field.
Background technology
The a large amount of native stone excavation waste produced in construction of hydropower plant process to need to be transported in selected Dumping Sites and abandons by certain requirement heap, dregs-blocking dam is one of important structure of Dumping Sites, play the effect of waste of blocking, simultaneously dregs-blocking dam also must possess the ponding can discharged behind dam in slag body, can the function such as maladjustment ground.At present, the hard material structure such as dregs-blocking dam multiselect concrete, stone masonry in hydroelectric project Dumping Sites, its Stability Analysis of Structures, intensity are high, survivable.But hard material dregs-blocking dam is high to dam foundation fundamental importance, dam foundation General Requirements is excavated to basement rock; As directly set up on the cover layer, then need further strengthening measures such as covering layer basis making cement consolidation groutings, after making covering layer basis reach some strength, as the dam foundation basis of hard material dregs-blocking dam, otherwise easily could there is gene basis sedimentation and cause dam body to destroy.In order to the ponding behind dam in slag body can be discharged, usually at concrete, stone masonry dregs-blocking dam dam body can pre-buried number row PVC drain pipe.
In sum, it is high to building dam fundamental importance for the hard material dregs-blocking dams such as the concrete in current hydroelectric project, stone masonry, cost is large, construction is complicated, the pre-buried gutter of dam body domestic demand, run into unfavorable foundation as soft base conditions such as deep covering layers, it can not adapt to distortion, the sedimentation of soft base, easily because the distortion of soft base, sedimentation cause dam body to destroy.
Utility model content
The purpose of this utility model is, the flexible blocking slag dam structure that a kind of structure is simple, quick construction, cost are low is provided, effectively can not only overcome covering layer basis and wait unfavorable geological condition, and can directly be based upon on covering layer basis, adapt to the distortion of soft base, sedimentation, possess drainage in dam body simultaneously, the functions such as waste of blocking, to overcome prior art deficiency.
The technical solution of the utility model: a kind of flexible blocking slag dam structure, comprise the dregs-blocking dam built on covering layer basis, described dregs-blocking dam moves back platform from bottom to top gradually by reinforced gabion to stack, the reinforced gabion Heterogeneous Permutation of every interlayer, and between adjacent reinforced gabion, adopt short muscle to be welded to connect the overall stairstepping dam body of formation one, in the bottom of stairstepping dam body, drainage culvert is set.
Aforesaid dregs-blocking dam is sandwich construction, to be stacked side by side for every layer and forms, the reinforced gabion Heterogeneous Permutation of every interlayer by multiple reinforced gabion.
Aforesaid reinforced gabion is made up of rectangle reinforcing cage and the reinforcing bar square being arranged on rectangle reinforcing cage top, in rectangle reinforcing cage, be filled with stone.
Aforesaid drainage culvert is concrete culvert pipe with great.
Owing to adopting technique scheme, the utility model has the advantage of: the utility model adopts multistory reinforced gabion to stack to be combined to form overall stairstepping dam body, its build is basically identical with the gravity dam formula build of conventional concrete, stone masonry dregs-blocking dam etc., not only Stability Analysis of Structures, and self possess certain " flexibility " feature, effectively can adapt to the feedback of the deformation to the soft base of covering layer of general degree, and do not destroy dam body, therefore it is low to building dam fundamental importance, can directly be based upon on the soft base of covering layer, construction is simple, and cost is low.Therefore, the utility model has the advantages such as structure is simple, quick construction, cost are low, can make full use of the Permeable characteristic of reinforced gabion combining structure and feed back the deformation of the soft base of covering layer simultaneously, playing waste effect of well blocking.

Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
As shown in Figures 1 and 2, a kind of flexible blocking slag dam structure of the present utility model, comprise the dregs-blocking dam 1 built on covering layer basis 4, described dregs-blocking dam 1 be by reinforced gabion 2 from bottom to top every layer move back platform 1.0m or 0.5m gradually and stack, reinforced gabion 2 Heterogeneous Permutation of every interlayer, and between adjacent reinforced gabion 2, adopt short muscle to be welded to connect the overall stairstepping dam body of formation one, in the bottom of stairstepping dam body, drainage culvert 3 is set.See Fig. 3, described reinforced gabion 2 is made up of rectangle reinforcing cage 2.1 and the reinforcing bar square 2.2 being arranged on rectangle reinforcing cage 2.1 top, the size of reinforced gabion 2 can make according to site operation, usually reinforced gabion 2 is of a size of 2m × 1.5m × 1m or 2m × 2m × 1m, the reinforcement welding that it is φ 16, φ 18 or φ 20 that reinforced gabion 2 can be selected by diameter makes, wherein array pitch 10 ~ 20cm between reinforcing bar, fill the crushed stone of particle diameter 30cm ~ 50cm in rectangle reinforcing cage 2.1 after, reinforcing bar square 2.2 is covered and is connected with rectangle reinforcing cage 2.1.
During construction, first in selected dregs-blocking dam position, remove the top layer foreign material etc. on upper caldding layer basis 4, carry out the flat construction in field, then pre-buried drainage culvert 3 in covering layer basis 4, reinforced gabion 2 now just can be adopted on covering layer basis 4 to move back platform from bottom to top gradually and to stack into stairstepping dam body, reinforced gabion 2 Heterogeneous Permutation of every interlayer, further, between each adjacent reinforced gabion 2, adopt short muscle to be welded to connect, make dregs-blocking dam 1 form an overall stairstepping dam body, increase its stability, and distortion, the sedimentation of soft base can be adapted to.In above-mentioned work progress, drainage culvert 3 can adopt concrete culvert pipe with great, and the quantity of drainage culvert 3 and diameter can design according to the draining size of Dumping Sites behind dam.If displacement is very little, even can not need drainage culvert 3, can directly utilize self water permeability of reinforced gabion 2 structure to discharge the ponding behind dam in waste body.Namely total floor height of reinforced gabion 2 constitutes the height of dregs-blocking dam 1, namely every layer of reinforced gabion 2 row constitute the thickness of the corresponding elevation of dregs-blocking dam 1, and the height of dregs-blocking dam 1 and thickness can calculate according to native stone pressure behind block height and the dam of stone waste body native behind dam to be determined.
