Abstract
The utility model discloses a kind of dam, including dam body, the downstream bulwark that is arranged at the upstream bulwark of dam body head upstream, is arranged at downstream at the top of dam body, the upstream bulwark connected with downstream bulwark it is integral, formed cross section be U-shaped monoblock type bulwark.The high barricade in upstream is connected by the utility model with downstream barricade, is formed overall progress antidetonation, can effectively be reduced its horizontal sliding and laterally topple.Meanwhile GSZ is laid in bulwark bottom, energy operative constraint soil body lateral displacement, dam body horizontal displacement and sedimentation are reduced, suitable for there are shockproof requirements and having the dam top structure of deep backfill body.
Description
Technical field
The utility model belongs to water power water conservancy project building technical field, more particularly to a kind of dam.
Background technology
Hydroenergy storage station realizes engineering " excavation and filling balance " to reduce to environmental destruction just as a kind of clean energy resource
It is increasingly becoming a kind of designer trends.To reduce caused a large amount of influences of the waste to surrounding enviroment, part in Process of Engineering Construction
Engineering combines itself lineament, and waste is backfilled into bottom storehouse.The CFRD later stage on deep backfill body
The rate of settling is big, the parting sealing of panel is produced stretcher strain, also has certain influence to the homeostasis of dam crest structure.
Important feature of the bulwark as dam crest, has the effect of wave resistance and barricade concurrently.Settlement and earthquake in dam
It is higher to the homeostasis and rigidity requirement of bulwark under power double action.The upstream bulwark of existing bulwark and downstream
Bulwark is independent, and cross section is generally L-shaped.
During earthquake operating mode, the big sedimentation of dam body itself, horizontal seismic inertial force, dam filing material dual thrust
Under, it is possible to create horizontal sliding and laterally topple, bulwark is more easily damaged.Existing wave wall structure pattern can not be well
Adapt to there are shockproof requirements in hydroenergy storage station and have the dam top structural requirement of deep backfill body.
Utility model content
There are shockproof requirements suitable for hydroenergy storage station in view of the above-mentioned problems, the utility model aims to provide one kind and have
Deep backfill body, it can effectively reduce bulwark horizontal sliding and laterally topple, and reduce the dam of dam body horizontal displacement and sedimentation
Structure.
The utility model solve problem technical scheme be：A kind of dam, including dam body, it is arranged at dam body head upstream
Upstream bulwark, the downstream bulwark for being arranged at downstream at the top of dam body, the upstream bulwark and downstream bulwark connect into whole
Body, form the monoblock type bulwark that cross section is U-shaped.
Further, it is provided with GSZ between monoblock type bulwark bottom at the top of the dam body.This is further improved
Scheme in, GSZ be used for constrain dam lateral displacement, reduce its horizontal displacement and sedimentation.
The hollow intracavitary of U-shaped of the monoblock type bulwark is equipped with bedding material, and road surface is equipped with bedding material.
Cable duct is provided with close to the side of upstream bulwark on road surface, is set in bedding material close to downstream bulwark side
There is drainpipe, for draining road top and bedding material internal water accumulation.
Further, it is close to upstream bulwark, is provided with inspection platform at its upstream, for dam maintenance repair.
The utility model wave wall uses structure of the cross section for " u "-shaped, and the high barricade in upstream and downstream barricade are connected
Connect, form overall progress antidetonation, can effectively reduce its horizontal sliding and laterally topple.Meanwhile geotechnological lattice are laid in bulwark bottom
Grid, energy operative constraint soil body lateral displacement, reduce dam body horizontal displacement and sedimentation, suitable for having shockproof requirements and having deep backfill
The dam top structure of body.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is bulwark plan of the present invention.
Fig. 2 is Fig. 1 drawing in side sectional elevation.
In figure：1st, monoblock type bulwark；2nd, cable duct；3rd, bedding material；4th, road surface；5th, drainpipe；6th, GSZ；7、
Dam body；9th, inspection platform；10th, upstream bulwark；11st, downstream bulwark.
Embodiment
As shown in Fig. 1~2, a kind of dam, including dam body 7, be arranged at the upstream bulwark 10 of the head upstream of dam body 7, set
It is placed in the downstream bulwark 11 in the top downstream of dam body 7.
The upstream bulwark 10 and downstream bulwark 11 connect it is integral, formed cross section be U-shaped monoblock type wave resistance
Wall 1.Overall progress antidetonation is formed, bulwark horizontal sliding can be effectively reduced and laterally topple.
The hollow intracavitary of U-shaped of the monoblock type bulwark 1 is equipped with bedding material 3.Road surface 4 is equipped with bedding material 3.On road
On face 4 cable duct 2 is provided with close to the side of upstream bulwark 10.In bedding material 3 row is provided with close to the side of downstream bulwark 11
Water pipe 5.
It is close to upstream bulwark 10, is provided with inspection platform 9 at its upstream.
GSZ 6 is provided between the top of dam body 7 and the bottom of monoblock type bulwark 1.GSZ 6 can operative constraint
Soil body lateral displacement, the horizontal displacement of dam body 7 and sedimentation are reduced, suitable for there are shockproof requirements and having the dam top of deep backfill body
Structure.
