Description
Technical field
The present invention relates to a kind of Precast Gallery, especially a kind of Precast Gallery of RCC dam.
Background technique
RCC dam is that the commonly used dam type in China quickly rolls it is advantageous that thin layer leads to storehouse rapid construction,
But excessive gallery template erection process is various, can occupy storehouse surface for the storehouse time, cause the interlayer intermittent time too long, influence interlayer
In conjunction with especially severe cold area is even more unfavorable, and the advantage of RCC dam rapid construction is made to be difficult to bring into play, past
Toward causing plan time to delay, causes damages to unit in charge of construction, entire construction organization plan is adversely affected, is shifted to an earlier date to hinge
It plays benefit and brings difficulty.
Therefore, how in gallery work progress, simplify operational procedure, more simplify Corridor Design, shorten storehouse surface
The standby storehouse time, so that the advantage of RCC dam rapid construction is brought into play, it 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 Precast Galleries for RCC dam, are not necessarily to frame
If template, without maintenance, storehouse surface space is saved in live handling installation, and the later period without disassembly, saves construction cost, can sufficiently send out
Wave the advantage of RCC dam rapid construction.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that: it is a kind of for the prefabricated of RCC dam
Gallery, which is characterized in that the second half side Precast Gallery including having the first half side Precast Gallery of bellmouth and with socket, the
The socket of the bellmouth of one half side Precast Gallery and the second half side Precast Gallery assembles to form one section of complete gallery, and first is half side prefabricated
The bellmouth of gallery is located at the top of gallery arc, and bellmouth is provided with slot, water-stop glue band is equipped on slot groove face, second is half side prefabricated
The socket of gallery is located at the top of gallery arc, plug is provided on socket, in the first half side Precast Gallery and the second half side prefabricated corridor
The front and back end in road and base contact surface are equipped with sealant.
The structure of the first half side Precast Gallery and the second half side Precast Gallery is that arc gallery side wall is connected to bottom
The middle part of plate pedestal, the integral prefabricated reinforced concrete structure into from steady structure.
The thickness of the first half side Precast Gallery and the second half side Precast Gallery is equal.
The sealant is polysulfide sealant, polyurethane sealant or silicone sealant.
The first half side Precast Gallery and the second half side Precast Gallery with a thickness of 30~40cm, length is 2.5~3m.
Beneficial effects of the present invention: without setting up template, without maintenance, storehouse surface space, later period are saved in live handling installation
Without disassembly, construction cost is saved, the advantage of RCC dam rapid construction can be given full play to.
Detailed description of the invention
Fig. 1 is perspective view of the present invention for the Precast Gallery of RCC dam.
Fig. 2 is the field erected schematic diagram of Fig. 1.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, 2, the Precast Gallery for RCC dam of the invention, it is half side including first with bellmouth
Precast Gallery 2 and the second half side Precast Gallery 3 with socket, the bellmouth of the first half side Precast Gallery 2 and second half side prefabricated
The socket of gallery 3 assembles to form one section of complete gallery, and the bellmouth of the first half side Precast Gallery 2 is located at the top of gallery arc, and bellmouth is set
It is equipped with slot 4, water-stop glue band 5 is equipped on 4 groove face of slot, the socket of the second half side Precast Gallery 3 is located at the top of gallery arc, inserts
It is provided with plug 6 on mouthful, end and base contact surface before and after the first half side Precast Gallery 2 and the second half side Precast Gallery 3
It is equipped with sealant 7.
Specifically, the structure of the first half side Precast Gallery 2 and the second half side Precast Gallery 3 is arc gallery side
Wall is connected to the middle part of bottom plate pedestal 1, the integral prefabricated reinforced concrete structure into from steady structure.Described first is half side prefabricated
The thickness of gallery 2 and the second half side Precast Gallery 3 is equal.The sealant 7 is polysulfide sealant, polyurethane sealant or silicone
Sealant.
The first half side Precast Gallery 2 and the second half side Precast Gallery 3 with a thickness of 30~40cm, length is 2.5~
3m。
Live handling installation, is directed at the first half side 2 arc of Precast Gallery for the plug 6 at the top of the second half side 3 arc of Precast Gallery
The decentralization of slot 4 at top is blocked, and the water-stop glue band 5 on slot 4 plays sealing effect after being extruded.When gallery connects section installation,
The sealant 7 of gallery end can play the role of sealing water proof every slurry.
Precast Gallery of the present invention, size is tailor-made according to design requirement, and gallery uses prefabrication, conserves, and after finished product, is transported to
Live handling installation, twice end and stitching position are equipped with measures of preventing water, prevent gallery from seeping water, then in mounted gallery two
Side making concrete carries out rolling completion construction.The invention avoids tear open in RCC dam gallery template in construction process
That unloads is cumbersome, avoids and becomes smaller bring inconvenience because template erection to roll storehouse surface.The present invention, which has, facilitates installation, without supporting
Shield from steady, save storehouse surface and rolls space without fixing, and the advantages that without dismantling, and it is fast to give full play of RCC dam
The advantage of speed construction.
The above embodiments are merely to illustrate technical idea and feature of the invention, and its object is to make skill in the art
Art personnel only cannot limit the scope of the patents of the invention with the present embodiment it will be appreciated that the contents of the present invention and implement accordingly,
Same changes or modifications made by i.e. all disclosed spirit, still fall in the scope of the patents of the invention.
