Description
Technical field
Hydraulic engineering field is the utility model is related to, more particularly to a kind of cofferdam.
Background technology
Cofferdam refers in hydraulic engineering construction, to build permanent water conservancy projects, the provisional building enclosure built.Its
Effect is to prevent water and soil from entering building and building position, in cofferdam internal drainage, to excavate foundation ditch, build building.One
As be mainly used in waterwork, except as formal building a part in addition to, cofferdam is typically removed after being finished.Build harbour
When, to create the dry construction condition of small range, that is, need to make above-mentioned cofferdam structure.But compared to the lake of land, Jiang Dao
Interior current are increasingly complex, and impact is larger, change its course when especially Jiang Dao makes dam, it is necessary to intercept on a large scale, and
Dykes and dams build that the cycle is longer, i.e., cofferdam must also have very high lasting impact resistance, it is therefore desirable to design a kind of resistance to punching
The cofferdam structure that hitting property is more preferable, intensity is higher.
Utility model content
The purpose of this utility model is to provide a kind of cofferdam, and having can the lasting shock proof advantage of high intensity.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of cofferdam, including both sides excavate shaping hillside soil layer, along hillside soil layer set pedestal and be arranged on two bases
Being blocked with horizontal made of gel sand gravel between seat；It is in that the jackstone being distributed up and down mixes that the pedestal, which includes being located at hillside soil layer surface,
Solidifying soil layer and toe gear shield, the part top layer of the hillside soil layer are excavated to form ladder, and the riprap concrete layer is matched somebody with somebody with ladder
Close, and the vertical anchor pole for being provided with while being fixedly connected with riprap concrete layer and hillside soil layer on the ladder；The jackstone
Native stone, which is provided with, between concrete layer and toe gear shield fills out slag blanket.
Using such scheme, hillside soil layer can be carried out to excavate operation with less with stair-stepping fit system, avoided
Stability that is excessive and destroying massif itself is destroyed to massif, and riprap concrete layer is connected to after upward slope soil layer, it is unlikely
It is excessive in the lower outer local pressure because of abutting portion, and cause tiltedly to be finally resulted in the landing of riprap concrete layer by crush-cutting；
And anchor pole is even more that both are connected as a single entity, to increase resistance moment of torsion；In addition, toe gear shield is due to stable in toe position
Property it is preferable, native stone fills out the Undertaking effect that slag blanket is kept off shield by toe, and reinforced undertaking to riprap concrete layer is abutted, equally
Riprap concrete layer also native stone is filled out slag blanket play a part of compacting, with hillside soil layer is embedding is integrated；So as on the hillside of both sides
Surface forms stable wear surface；On this basis, horizontal the blocking of cement sand and gravel formation is poured between two wear surfaces
With good stability, it is not easy to separate with massif, remains that high intensity carries.
More preferably：The toe gear shield includes the blocks that multiple superimposions form, and the blocks includes
Reinforced gabion and gelling sandy gravel stratum, the gelling sandy gravel stratum are filled and wrap up reinforced gabion.
Using such scheme, reinforced gabion provides tension bearing capacity, and gelling sand stone layer provides measuring body ability, Liang Zhejie
Conjunction can form fabulous water pressure resistance；, and can be with advance comprising and blocks can be with rapid shaping, and the wetting for reducing water is done
Disturb.
More preferably：It is described horizontal to block including multiple blocks being formed by stacking and the metamorphosis for being wrapped in blocks surrounding
Concrete layer.
Using such scheme, a kind of concrete between normality and between rolling, it is set to possess shaking for normal concrete
Smash performance, while but also with the advantage such as grinding concrete construction is fast, intensity is high, blocks that can be with fabulous reinforcement after compound
Between structural strength, to resist stiffness hydraulic pressure.
More preferably：The toe gear shield is provided with five on the vertical vertical section along the solum horizontal of hillside
Individual blocks, five blocks (361) are distributed as two, upper strata and lower floor three, and five blocks (361) shapes
Into breach towards hillside.
Using such scheme, slag blanket formation can be filled out when slag blanket is formed and abutted to native stone towards massif being filled out with native stone
Support holding power, keep force stability.
More preferably：The reinforced gabion includes lid and cage body, and the lid and cage body are included around composition
The framework of steel reinforcement of cuboid and in the distribution bar in the netted square face for being filled in framework of steel reinforcement and being divided into.
Using such scheme, framework of steel reinforcement is main load-carrying construction, and helical pitch is longer, it is necessary to from thicker reinforcing bar, and
The local load-carrying construction of distribution bar, is local pressure train of thought after the completion of pouring, and the stress of stiffener and gelling sandstone joins
System.
More preferably：Four top margins of the cage body are provided with suspension ring.
Using such scheme, suspension ring can carry out suspension hook and put in order to apparatus.
More preferably：The native stone fills out slag blanket surface and is provided with slope protection concrete layer.
Using such scheme, avoid filling out the situations such as slag blanket forms Rolling Stone or punching falls, and fill out slag blanket as after internal layer, due to it
Locally variable, but and can carries out fine motion, can be with fabulous formation anti-seismic structure so that filling out between slag blanket and each layer.
More preferably：The top of the riprap concrete layer, which is set, fills out slag formation roadbed, is provided with the roadbed
With cofferdam road made of normal concrete.
Using such scheme, passage of the cofferdam road as the conveying of blocks or other materials, filling out slag blanket can weaken
Caused vibrations in course of conveying.
In summary, the utility model has the advantages that：
The composition complementary structure that slag blanket and toe gear shield are filled out with riprap concrete layer, native stone is formed on the hillside surface of both sides
Stable wear surface；On this basis, horizontal the blocking of cement sand and gravel formation is poured between two wear surfaces, is had fine
Stability, be not easy to separate with massif, remain high intensity carry.
