Description
Technical field
The present invention relates to a kind of RCC dam, especially a kind of RCC dam gallery arrangement, construction method are main
It is used for Compacted Concrete Gravity Dam Section and the construction of arch dam foundation gallery.
Background technique
RCC dam is a kind of new concrete dam, is risen in late 1970s, dam material mainly uses
The concrete of dry poor-water mud.Relative to normality concrete dam, quickly put in storage, pave, rolling be RCC dam most
Big advantage only accomplishes that above three is quick, just can guarantee the quality of grinding coagulation soil pouring quality and Coating combination.But often
RCC dam is at foundation construction position, the case where there is vertical and horizontal gallery interlaced arrangements, by concrete pouring bin
Face segmentation rolled so that concrete is difficult to, it has to become normal concrete or abnormal concrete poured, and this two
Person's concrete calorific value is big, and temperature control difficulty is big, in fact it could happen that large-scale distress in concrete brings safety hidden to safety of dam body
Suffer from, how to solve dam foundation gallery arrangement, facilitating grinding concrete construction is a urgent problem to be solved.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of RCC dam gallery arrangements, construction method, can be with
The segmentation for reducing grinding coagulation soil lift surface, accelerates the speed of perfusion of concrete, ensure that construction quality.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: a kind of RCC dam gallery arrangement,
Construction method, comprising the following steps:
(1) the main grout curtain gallery of sunk type, sunk type collector drain and sunk type are excavated on excavating the dam foundation completed
Cross traffic collector drain；
(2) corridor is drained in the main grout curtain gallery side wall of sunk type, sunk type collector drain side wall, sunk type cross traffic
Road side wall distinguishes casting concrete, at the top of the main grout curtain gallery of sunk type, at the top of sunk type collector drain and sunk type is horizontal
Prefabricated arch ring is set at the top of to traffic collector drain；
(3) grout curtain is done in the main grout curtain gallery of sunk type, drainage hole is set, be arranged in sunk type collector drain and arrange
Water hole；
(4) levelling blinding concrete is poured in the dam foundation and prefabricated arch ring top, prefabricated arch ring overhead height control is pouring
Under levelling blinding concrete, after the completion of pouring levelling blinding concrete and pouring, interference-free carries out top grinding coagulation soil
Pouring construction.
The main grout curtain gallery side wall casting concrete thickness >=1.0m of sunk type, sunk type cross traffic collector drain side
Wall casting concrete thickness >=0.5m, sunk type collector drain side wall casting concrete thickness >=0.5m.
Levelling blinding concrete is poured in the dam foundation and prefabricated arch ring top, levelling blinding concrete is more than the dam foundation and Prefabricated arch
Enclose at least 0.3m.
The RCC dam is Compacted Concrete Gravity Dam Section or rolled concrete arch dam.
The beneficial effects of the present invention are: can glitch-free progress top grinding coagulation soil pour work, reduction rolls mixed
The segmentation of solidifying soil lift surface, accelerates the speed of perfusion and construction quality of concrete.Simultaneously can reduce abnormal concrete and often
The dosage of state concrete simplifies Concrete Temperature Control measure, reaches guarantee construction quality, the purpose of investment reduction.
Detailed description of the invention

Fig. 2 is gallery partial enlargement diagram of the invention.
Fig. 3 is gallery plan view of the invention.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1-3, RCC dam gallery of the invention is arranged, construction method, comprising the following steps:
(1) the main grout curtain gallery 2 of sunk type, sunk type collector drain 3 are excavated on excavating the dam foundation 1 completed and are sunk
Formula cross traffic collector drain 4；
(2) in main 2 side wall of grout curtain gallery of sunk type, 3 side wall of sunk type collector drain, the draining of sunk type cross traffic
4 side wall of gallery distinguishes casting concrete 5,2 top of the main grout curtain gallery of sunk type, 3 top of sunk type collector drain and under
Prefabricated arch ring 6 is set at the top of heavy formula cross traffic collector drain 4；
(3) grout curtain 7 is done in the main grout curtain gallery 2 of sunk type, drainage hole 8 is set, is set in sunk type collector drain 3
Set drainage hole 8；
(4) levelling blinding concrete 9 is poured in the dam foundation 1 and 6 top of prefabricated arch ring, prefabricated 6 overhead height of arch ring control exists
It pours under levelling blinding concrete 9, after the completion of pouring levelling blinding concrete 9 and pouring, interference-free carries out top and rolls
10 pouring construction of concrete.
Main 2 side wall casting concrete thickness of the grout curtain gallery >=1.0m of sunk type drains corridor in sunk type cross traffic
4 side wall casting concrete thickness of road >=0.5m and in 3 side wall casting concrete thickness of sunk type collector drain >=0.5m.
Pour levelling blinding concrete 9 in the dam foundation 1 and 6 top of prefabricated arch ring, levelling blinding concrete 9 be more than the dam foundation 1 and
The prefabricated at least 0.3m of arch ring 6.
The RCC dam is Compacted Concrete Gravity Dam Section or rolled concrete arch dam.
Below by taking gravity dam as an example, it is described in detail:
