Abstract
The invention discloses a kind of cement sand and gravel buttress dams, including the dam foundation and the dam body being arranged on the dam foundation, the dam body include antiseepage watertight layer and be arranged after antiseepage watertight layer and with the vertically arranged one group of buttress of dam body axis, between buttress be filled with cement sand and gravel；The antiseepage watertight layer is by the dam foundation to dam crest gradually thinning trapezium structure；The antiseepage watertight layer is poured using armored concrete, and the gradient is between gravity dam and cemented gravel dam.The present invention shares upstream water pressure using multistage buttress, reduce the stress of dam body cement sand and gravel material, so as to reduce cement sand and gravel section, it not only can reach the purpose of optimization construction investment, and demand to sand gravel material reserves at dam site can be reduced, improve the adaptability of cemented gravel dam.
Description
Technical field
The present invention relates to a kind of cement sand and gravel buttress dams, belong to hydraulic and hydroelectric engineering technical field.
Background technique
Cemented gravel dam is a kind of novel dam developed in recent years, and sectional form is between cement sand and gravel between face
Between sheetpile masonry dam and concrete gravity dam.Cement sand and gravel dam construction technique is in grinding concrete dam technology and panel enrockment
A kind of novel dam construction technique to grow up on the basis of dam construction technique, using the sand gravel material for being added to a small amount of cementitious material
(including sand, ballast, gravel etc.) builds a dam, and is constructed using efficient cubic metre of earth and stone Transport Machinery and compacting machinary, makes sand gravel material
Become continuous rigid body from bulk solid.Cement sand and gravel dam construction technique is with safe and reliable, speed of application is fast, simple process, warp
Ji property is good, reduces the advantages that environmental disruption.
Cemented gravel dam is needed due to the characteristics of gathering materials on the spot using the riverbed sandy gravel near dam site, therefore for
Sandy gravel content less region in riverbed is not appropriate for using this kind of dam type (if optionally stock ground exploitation, loses economy
Advantage).Simultaneously as this kind of dam type figure heavy force dam body type is big, the riverbed sandy gravel needed is also more, therefore, very much
The less riverbed of natural grit granulation reserves, this kind of dam type popularization are restricted.
Summary of the invention
The purpose of the present invention is to provide a kind of cement sand and gravel buttress dam, which rationally utilizes buttress to bear lotus
It carries, the gradient of cement sand and gravel above and below the dam dam slope can be reduced, to reach optimization section, reduce cement sand and gravel material utilization amount
Purpose.
Technical solution of the present invention: a kind of cement sand and gravel buttress dam, including the dam foundation and the dam body being arranged on the dam foundation,
The dam body include antiseepage watertight layer and be arranged after antiseepage watertight layer and with the vertically arranged one group of branch of dam body axis
Pier is filled with cement sand and gravel between buttress.
Further, the antiseepage watertight layer is by the dam foundation to dam crest gradually thinning trapezium structure.
Further, the antiseepage watertight layer is poured using armored concrete, and the gradient is between gravity dam and gelling sand
Between gravel dam.
Further, the buttress is trapezoidal plate structure, and is poured using armored concrete.
By adopting the above-described technical solution, the present invention has the advantages that the present invention shares upper water using multistage buttress
Pressure, the stress for reducing dam body cement sand and gravel material not only can reach optimization work so as to reduce cement sand and gravel section
The purpose of journey investment, and the demand to sand gravel material reserves at dam site can be reduced, improve the adaptability of cemented gravel dam.
Detailed description of the invention
The main view that Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the perspective view of structural schematic diagram of the invention
Description of symbols: the 1- dam foundation, 2- buttress, 3- antiseepage watertight layer, 4- cement sand and gravel.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and examples to this hair
It is bright to be described in further detail.
The embodiment of the present invention: the structural schematic diagram of cement sand and gravel buttress dam is as shown in Figures 1 and 2, including the dam foundation 1 with
And the dam body on the dam foundation 1 is set, the dam body include antiseepage watertight layer 3 and be arranged after antiseepage watertight layer 3 and with
The vertically arranged one group of buttress 2 of dam body axis, the buttress 2 is trapezoidal plate structure, and armored concrete is used to pour,
Cement sand and gravel 4 is filled between buttress 2.The antiseepage watertight layer 3 is by the dam foundation to dam crest gradually thinning trapezium structure；
The antiseepage watertight layer 3 is poured using armored concrete, and the gradient is between gravity dam and cemented gravel dam.
The present invention shares upstream water pressure using multistage buttress 2, reduces the stress of dam body cement sand and gravel 4, so as to
The section for reducing cement sand and gravel 4, not only can reach the purpose of optimization construction investment, but also can reduce to the gravel that is gelled at dam site
The demand of 4 reserves of stone, improves the adaptability of cemented gravel dam.
