Abstract
The utility model discloses a reinforced concrete prefabricated gallery structure of a roller compacted concrete dam. The reinforced concrete prefabricated gallery structure comprises dam body roller compacted concrete (7) and a prefabricated gallery body (1) which is arranged in the dam body roller compacted concrete (7) and is of a city door opening type concrete structure, and is characterized in that a distorted concrete layer (6) is arranged between the prefabricated gallery body (1) and the dam body roller compacted concrete (7), and the prefabricated gallery body (1) is formed by longitudinal load-bearing reinforcing steel bars (2), annularly-distributed reinforcing steel bars (3) and concrete in a poured mode, and provided with inserted reinforcing steel bars (4) going deep into the distorted concrete layer (6). Compared with a cast-in-place gallery, the reinforced concrete prefabricated gallery structure has the advantages that a whole fracture section bar concrete prefabricated gallery structure is adopted, the construction period of long-distance inner-dam gallery construction is effectively shorted, construction interference is reduced, and the rapid and continuous construction advantage of the roller compacted concrete dam is developed to the greatest degree. The reinforced concrete prefabricated gallery structure is an economical and practicable gallery structure.
Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering technical field, relates to the reinforced concrete prefabricated gallery structure of a kind of RCCD (Roller Compacted Concrete Dam).
Background technology
The features such as it is simple that RCCD (Roller Compacted Concrete Dam) has construction technology, and speed of application is fast, in Hydraulic and Hydro-Power Engineering, application is very extensive.In RCCD (Roller Compacted Concrete Dam) structural configuration, for meeting the functional requirements such as traffic, grouting, monitoring, the gallery of long distance need to be set.The work such as conventional cast-in-situ concrete gallery need carry out that reinforcing bar binding, masterplate frame are vertical, concrete transportation puts in storage and vibrates, construction is disturbed large, and after normality cast-in-situ concrete gallery is built, need to wait for the time age of concrete, treat that intensity reaches requirement and just can carry out top concrete construction, whole normal concrete gallery construction period is longer, can not bring into play the feature of RCCD (Roller Compacted Concrete Dam) rapid construction.
Summary of the invention
The purpose of this utility model is to provide a kind of RCCD (Roller Compacted Concrete Dam) reinforced concrete prefabricated gallery structure, to overcome the technical problem of gallery long construction period of prior art.
For realizing the purpose of this utility model, the utility model has adopted such technical scheme:
The reinforced concrete prefabricated gallery structure of RCCD (Roller Compacted Concrete Dam) of the present invention, comprise dam body roller compacted concrete and the Precast Gallery of establishing gateway opening steel bar concrete structure therein, between Precast Gallery and dam body roller compacted concrete, be provided with abnormal concrete layer, the abutment wall ranges of thicknesses of abnormal concrete layer is 50cm, crown thickness is 90cm, abnormal concrete layer is a transition zone between Precast Gallery and dam body roller compacted concrete, guarantees the stability of the two combination; Precast Gallery is formed by Reinforcement, hoop distribution reinforcement and concreting, by precasting yard is prefabricated complete after transporting and hoisting to installation position; Precast Gallery is provided with the joint bar going deep in abnormal concrete layer, and joint bar gos deep into 50cm in abnormal concrete layer, by joint bar, Precast Gallery is firmly fixed in abnormal concrete layer, guarantees the reliability that Precast Gallery is installed.
Further, Precast Gallery crown center of arc angle is less than 180 °.The wall thickness of Precast Gallery is 50cm.In addition, Precast Gallery is also provided with the suspension ring for its lifting, and suspension ring are located in Precast Gallery crown, and with Reinforcement inside reinforcing bar be weldingly connected.
Compared with cast-in-place gallery, the utility model adopts full section muscle coagulation Precast Gallery structure.Effectively reduce length apart from gallery construction construction period, reduce construction and disturb, bring into play to greatest extent the quick feature of construction continuously of RCCD (Roller Compacted Concrete Dam).It is a kind of economically viable gallery structure.
brief description of the drawings
Fig. 1 is section structure schematic diagram of the present utility model;
Description of reference numerals: 1-Precast Gallery, 2-Reinforcement, 3-hoop distribution reinforcement, 4-joint bar, 5-suspension ring, 6-abnormal concrete layer, 7-dam body roller compacted concrete.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the reinforced concrete prefabricated gallery structure of this RCCD (Roller Compacted Concrete Dam) of the present utility model, comprises reinforced concrete Precast Gallery 1, and Precast Gallery 1 is formed by Reinforcement 2, hoop distribution reinforcement 3 and concreting.Precast Gallery 1 section is gateway opening type, and crown center of arc angle is less than 180 °.Precast Gallery 1 thickness is 50cm.Joint bar 4 is cast in the abnormal coagulating layer soil of reinforced concrete prefabricated gallery 1 abutment wall 6 interior 50cm.Suspension ring 5 are cast in Precast Gallery 1 crown, and weld with Reinforcement 2 inner side reinforcing bars.Abnormal concrete layer 6 abutment wall ranges of thicknesses are 50cm, and crown thickness is three, and to roll bed thickness be 90cm.
When the utility model is implemented according to following step:
The utility model gallery adopts the prefabricated assembled construction again of full section, reinforced concrete prefabricated gallery 1 carries out prefabricated at precasting yard, scene is lifted by crane one by one Precast Gallery 1 and is carried out assembled by suspension ring 5 with crane along gallery axis direction, build afterwards upstream and downstream dam concrete, joint bar 4 welds with Precast Gallery 1 outside reinforcing bar and gos deep into the interior 50cm of abnormal concrete layer 6, Precast Gallery 1 is abutment wall 50cm in addition around, to roll bed thickness be that 90cm scope is built abnormal concrete layer 6 to above three of crown, carries out afterwards dam body roller compacted concrete 7 and construct.It is prefabricated in advance that Precast Gallery 1 adopts set shaped steel formwork to carry out at precasting yard, effectively reduces length apart from gallery construction construction period, reduces construction and disturb, and brings into play to greatest extent the quick feature of construction continuously of RCCD (Roller Compacted Concrete Dam).It is a kind of economically viable gallery structure.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
