Abstract
Emergency flood fighting technical field is the utility model is related to, more particularly to a kind of dam bank ruggedized construction, IPC code is E02B 3/12.Bank ruggedized construction in dam of the present utility model, including increasing masonry, cement-grouting consolidation body, dirt induration, concrete cover, top GSZ, turf and Xin Ji soil, increase the top that masonry is located at original masonry, cement-grouting consolidation body is located at the joint portion of original masonry and original base soil；Dirt induration is located at the native stone joint portion for increasing masonry and new and old base soil, and top GSZ is arranged on the top of new base soil, and turf is arranged on the top of top GSZ, and concrete cover, which is arranged on, increases masonry and dirt induration top.Bank ruggedized construction in dam of the present utility model, without large scale equipment during construction, a line flood control worker can rapid construction.
Description
Technical field：
Emergency flood fighting technical field is the utility model is related to, more particularly to a kind of dam bank ruggedized construction, IPC international monopolies point
Class-mark is E02B 3/12.
Background technology：
Conduct, dangerous section and the bank-protection works in the northern river such as the Yellow River, the base soil as dam bank main body is typically all by locality
Loam compacting fill and form, only wrapped up in upstream face with placed rockfill, cost is relatively low.The loam that the north is built a dam, it is consolidated
Power and impact resistance are far smaller than southern clay, and under the long period of soaking, impact in middle long water level, the base soil of native stone joint portion can quilt
Current are washed in a pan away from placed rockfill gap；Rainy season continuous rainfall can also be let out from the top of dam bank under native stone joint portion, by soil
The base soil of stone joint portion washes away from placed rockfill gap.A large amount of losses of base soil, make dam bank main body that depression, deformation occur, lead
Cause dam shore pier to sting, the dangerous situations such as thorax of bursting, if trimming is reinforced not in time, whole dam bank can be caused to be squashed.
Utility model content：
The purpose of this utility model, which is to provide, a kind of to be used to rebuild the dam bank for base soil scour wastage occur
The structure of reinforcing, technical scheme is as follows used by the utility model：
A kind of dam bank ruggedized construction, including increase masonry, cement-grouting consolidation body, dirt induration, concrete cover, top soil
Work grid, turf and Xin Ji soil, wherein, the masonry of increasing is laid dry stone structure, described to increase block positioned at original masonry top
The vertical section of body is right-angled trapezium, and the bottom width for increasing masonry is bigger 0.5m than the top width of original masonry；Institute
State the joint portion that cement-grouting consolidation body is located at original masonry and original base soil；The new base soil is arranged on original base soil top；It is described
Dirt induration vertical section is " L " shape, positioned at the native stone joint portion for increasing masonry base soil native and new with original base, thickness 0.4
Rice；The top GSZ is arranged on the top of the new base soil, and the turf is arranged on the top GSZ top,
The concrete cover increases masonry and the dirt induration top described in being arranged on.
Bank ruggedized construction in dam of the present utility model, simple in construction, low cost, without large scale equipment, a line flood control during construction
Worker can rapid construction.Its innovative point is mainly reflected in following aspects：(1), between original masonry and original base soil
Cement injection mortar, consolidation is filled into the space of original soil stone binding site, effectively prevent scour of the middle long water level to base soil；(2)
Fill 1: 4 dirt between the new native stone binding site that masonry and Xin Ji soil formed is increased, when can effectively prevent great flood or
To the scour of new base soil during continuous rainfall；(3) GSZ is set at the top of new base soil, turf is laid on GSZ,
Both the impact resistance at the top of dam bank had been improved, the survival rate of turf has been improved again, has beautified environment.
Brief description of the drawings：
Fig. 1：Bank ruggedized construction schematic diagram in dam of the present utility model
In figure, 1 is original masonry, and 2 is increase masonry, and 3 be cement-grouting consolidation body, and 4 be dirt induration, and 5 be coagulation earth mulch
Plate, 6 be top GSZ, and 7 be turf, and 8 be original base soil, and 9 be new base soil, and 10 be root Shitai County, 11 for new base it is native with it is original
Base soil line of demarcation.
Embodiment：
Referring to Fig. 1, bank ruggedized construction in dam of the present utility model, including increase masonry 2, cement-grouting consolidation body 3, dirt induration
4th, concrete cover 5, top GSZ 6, turf 7 and Xin Ji soil 9, increase masonry 2 and be located at original top of masonry 1, it is and original
Masonry 1 is all same placed rockfill structure, and the masonry 2 and the vertical section of original masonry 1 increased all is right-angled trapezium, described
The bottom width for increasing masonry 2 is bigger 0.5m than the top width of original masonry 1.The cement-grouting consolidation body 3 is located at original block
The native stone joint portion of body 1 and original base soil 8, the mortar injection prepared by accelerated cement, consolidation are formed, and can effectively prevent native stone
The base soil scour of joint portion is lost in.
The new base soil 9 is arranged on native 8 tops of original base, and forming using local loam compaction in layers is filling new base soil 9
Before, should be native loose with the plane of original base soil 8 at original base soil line of demarcation 11 by new base, to improve the combination of the new and old soil body.
The vertical section of the dirt induration 4 is " L " shape, positioned at the soil for increasing masonry 2 and original base 8 and Xin Ji of soil soil 9
Stone joint portion, thickness are 0.4 meter, are filled and tamped and formed by 1: 4 dirt (i.e. the mass ratio of lime and soil is 1: 4).
The top GSZ 6 is arranged on the top of the new base soil 9, and the turf 7 is arranged on the top geotechnique
The top of grid 6, the concrete cover 5, which is arranged on, described increases masonry 2 and the top of dirt induration 4.
In the bottom of original masonry 1, side is provided with root Shitai County 10 near water, for erosion control mulch.
Bank ruggedized construction in dam of the present utility model, it can be carried out after scour destruction occurs in dam bank by a line flood control troop
Construction, without large-scale construction equipment, and required material is all the standing flood control material in flood control warehouse, and construction is quick, low cost, can be with
It is widely used in river, reservoir, Hu Bo dam bank to reinforce.
