Abstract
The utility model discloses a kind of low discharge rock matter drainage tunnel structure, comprise the internal layer concrete lining (2) being arranged on drainage tunnel (1) end arch and abutment wall, and the outer concrete lining cutting (3) be arranged in internal layer concrete lining (4), underplate concrete lining cutting (4) one end of drainage tunnel (1) bottom is provided with gutter (5).The utility model is when underplate concrete lining cutting (4) of construction drainage hole (1) bottom, only need reserve a breach in underplate concrete lining cutting (4) one end, just Quick drainage ditch (5) can be formed, not only efficiency of construction improves greatly, use manpower and material resources sparingly, and avoid gutter explosion can not to cause constructing and need the problem of hand excavation, accelerate construction speed.<b/>
Description
Technical field
The utility model relates to a kind of low discharge rock matter drainage tunnel structure, belongs to construction of hydro project technical field.
Background technology
In hydraulic engineering construction, build the important measures that drainage tunnel is some important building drainage and step-downs.In traditional water conservancy engineering, after rock matter drainage tunnel base plate of being everlasting has excavated, then carrying out base plate gutter excavation, and carrying out concrete lining.But, during this section structure excavation gutter, because gutter size is less, can not blast working, can only hand excavation be adopted, for longer rock matter drainage tunnel, then need a large amount of personnel to excavate, wasting manpower and material resources, have a strong impact on the duration of engineering.
Utility model content
The purpose of this utility model is, provides that a kind of structure is simple, easy construction, effectively can improve the low discharge rock matter drainage tunnel structure of construction speed, to overcome prior art deficiency.
The technical solution of the utility model: a kind of low discharge rock matter drainage tunnel structure, comprise the internal layer concrete lining being arranged on arch and abutment wall at the bottom of drainage tunnel, and the outer concrete lining cutting be arranged in internal layer concrete lining, the underplate concrete lining cutting one end bottom drainage tunnel is provided with gutter.
Further, bottom gutter, sand finish is provided with.
Owing to adopting technique scheme, the utility model has the advantage of: during the underplate concrete lining cutting of the utility model bottom construction drainage hole, only need reserve a breach in underplate concrete lining cutting one end, just Quick drainage ditch can be formed, not only efficiency of construction improves greatly, use manpower and material resources sparingly, and avoid gutter explosion can not to cause constructing and need the problem of hand excavation, accelerate construction speed.Therefore, the utility model can form base plate gutter, cavern fast and efficiently, a large amount of saving manpower and duration, can extensive use in other Yan Zhi caverns.
Accompanying drawing explanation
Fig. 1 is section structure schematic diagram of the present utility model.
Description of reference numerals: 1-drainage tunnel, the concrete lining of 2-internal layer, 3-rotating shaft, the lining cutting of 4-underplate concrete, 5-gutter, 6-sand finish.
Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of low discharge rock matter drainage tunnel structure of the present utility model, comprise the internal layer concrete lining 2 being arranged on drainage tunnel 1 end arch and abutment wall, and the outer concrete lining cutting 3 be arranged in internal layer concrete lining 4, underplate concrete lining cutting 4 one end bottom drainage tunnel 1 is provided with gutter 5, and the size in described gutter 5 is arranged voluntarily according to drainage requirement.Further, bottom gutter 5, be provided with sand finish 6, make bottom gutter 5 more smooth, improve the drainage efficiency in gutter 5.
Claims (2)
1. a low discharge rock matter drainage tunnel structure, comprise the internal layer concrete lining (2) being arranged on drainage tunnel (1) end arch and abutment wall, and the outer concrete lining cutting (3) be arranged in internal layer concrete lining (4), it is characterized in that: underplate concrete lining cutting (4) one end of drainage tunnel (1) bottom is provided with gutter (5).
