Abstract
The utility model discloses a kind of high steep landform Arch Dam Abutments of cave type to excavate structure, it includes hanging body (2) by the feet positioned at the construction hole (1) of Arch Dam Abutment, the base surface (3) of the Arch Dam Abutment of construction hole (1) outlet lower section and hole (1) outlet top of constructing, and is equipped with comprehensive support (4) to the hole face of construction hole (1), the scar of top hung body (2) by the feet and excavate formation.The utility model is using cave-dwelling type rock cut instead of conventional fluting open cut; the excavation height and range of Arch Dam Abutment side slope can be reduced; it reduces excavation and support engineering amount is small; reduce side slope safety risk; it shortens the construction period, reduces investment outlay, energy effective protection slope ecological environment and raising dam shoulder stability; with preferable mixed economy and social benefit, it is more suitable for the steep geology orographic condition in the high slope in mountain.
Description
Technical field
The present invention relates to hydraulic and hydroelectric engineering technical fields, and in particular to a kind of high steep landform Arch Dam Abutment excavation of cave type
Structure.
Background technique
With the development of the social economy, water demand further increases, Facing Hydraulic Project complicated geology landform
Condition, engineering construction difficulty are big.For building induced joint in the steep river valley Shan Gaopo, the further investigation of abutment excavation mode and
Technological innovation, it appears be still important and urgent.Conventional Arch Dam Abutment excavation is all made of open cut, the ground more precipitous for two sides massif
Shape has following defects that slope excavating height and range are larger, and side slope safety risk is higher, excavates and support engineering amount is larger,
Duration is longer, invests larger etc..
Summary of the invention
The purpose of the present invention is to solve the Railway Projects mentioned in background technique, and a kind of cave type proposed is high steep
Landform Arch Dam Abutment excavates structure.
To achieve the goals above, present invention employs following technical solutions:
A kind of high steep landform Arch Dam Abutment of cave type of the utility model excavates structure, it includes applying positioned at Arch Dam Abutment
Work hole, construction hole outlet below Arch Dam Abutment base surface and construction hole outlet above hang body by the feet, to construction hole hole face,
Hanging body by the feet and excavating the scar formed for top is equipped with comprehensive support.
Wherein, above-mentioned combined support measures include anchor pole, shotcrete with mesh and anchor cable, can increase steel branch when necessary
Support.
By adopting the above-described technical solution, the utility model is compared with the prior art, the utility model uses cave type
It excavates instead of conventional fluting open cut, the excavation height and range of Arch Dam Abutment side slope can be reduced, reduce excavation and branch nurse
Journey amount is small, reduces side slope safety risk, shortens the construction period, reduce investment outlay, and energy effective protection slope ecological environment and raising dam abutment are steady
It is qualitative, there is preferable mixed economy and social benefit, be more suitable for the steep geology orographic condition in the high slope in mountain.
Detailed description of the invention
A kind of high steep landform Arch Dam Abutment of cave type Fig. 1 of the invention excavates cross-sectional view of the structure；
A kind of high steep landform Arch Dam Abutment of cave type Fig. 2 of the invention excavates structure front view.
Description of symbols: 1- construction hole, 2- hang body, 3- base surface, 4- comprehensive support by the feet.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, but not as any limitation of the invention.
Please refer to Fig. 1-Fig. 2:
The embodiments of the present invention: the structure of the utility model is as shown in Figure 1, it includes the construction positioned at Arch Dam Abutment
Hole 1, construction excavate downwards the base surface 3 for forming Arch Dam Abutment in hole 1, and the outlet of hole 1 top of constructing hangs body 2 by the feet, to hole 1 of constructing
Hole face, top hangs body 2 by the feet and excavates the scar formed using comprehensive support 4.
When the utility model is used: first implementing a construction hole 1 in the position of Arch Dam Abutment massif, crest elevation, applying
It is layered downwards and digs according to the design profile and side slope angle of dam abutment in work hole 1, the base surface 3 of Arch Dam Abutment is formed, for applying
The body 2 of hanging by the feet of 1 top of work hole reduces disturbance to the greatest extent, and only the rock mass more broken to outside is cleared up, and to construction hole 1, hangs body 2 by the feet
Comprehensive support 4 is used with the scar formed is excavated.
It is above specific application example of the invention, there are other embodiments of the invention, all to use equivalent replacement
Or the technical solution that equivalent transformation is formed, it all falls within protection scope of the presently claimed invention.
