Abstract
Disclosed is a high cantilever long-span U-shaped groove composite construction. The high cantilever long-span U-shaped groove composite construction has the advantages of being good in structural integrity, simple in structure, convenient to construct and economical in engineering investment. The high cantilever long-span U-shaped groove composite construction comprises a U-shaped groove structure (1). Anti-pull reinforced piles (2) are arranged on the outer side of the U-shaped groove structure (1) along the longitudinal direction at intervals. A connecting beam (3) which is fixedly connected with the U-shaped groove structure (1) and the anti-pull reinforced piles (2) is arranged on the top portion of the U-shaped groove structure (1) and the top portion of the anti-pull reinforced pile (2).
Description
Technical field
The utility model relates to a kind of civil engineering retaining structure, particularly the U-shaped groove composite construction of a kind of high cantilever large span
Background technology
In recent years China's urban construction, railway construction fast development, a large amount of lower large span excavation paragraphs of wearing has appearred in city municipal administration, railway terminal and station, owing to be subjected to the requirements such as Effect of Underground Water Level and retaining structure outward appearance, need to arrange down and wear the U-shaped groove Structural Engineering of high cantilever large span.Because U-shaped groove cantilever is high, it is stressed large, if only resist external force by strengthening physical dimension and intensity, its construction investment is higher; Simultaneously because U-shaped groove structural span is large, traditional in U-shaped groove structural top stull be set and improve its method stressed and that save investment and do not have realization condition.Therefore, active demand is a kind of effectively to improve the neotectonics of U-shaped groove structure stress, simple in structure, easy construction and saving construction investment, and meets the requirement of environmental protection.
The utility model content
One of technical problem to be solved in the utility model provides the U-shaped groove composite construction of a kind of high cantilever large span, the characteristics of have that structural integrity is good, simple in structure, easy construction, construction investment economizing.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The U-shaped groove composite construction of high cantilever large span of the present utility model comprises U-shaped groove structure, and it is characterized in that: the outside of described U-shaped groove structure longitudinally interval arranges the tension reinforcing pile, at the top of U-shaped groove structure and tension reinforcing pile fixed with it tie-beam is set.
The beneficial effects of the utility model are, effectively solve U-shaped groove structure and improved the problems such as its structure stress and construction investment are large because stressed large, the span of high cantilever construction can't arrange stull in structural top greatly, its structural integrity is good, simple in structure, easy construction, construction investment economize, and meet environmental requirement, have wide popularizing application prospect.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the schematic cross-sectional view of the U-shaped groove composite construction of the high cantilever large span of the utility model;
Fig. 2 is the floor map of the U-shaped groove composite construction of the high cantilever large span of the utility model.
The title of member shown in the figure and corresponding mark: U-shaped groove structure 1, tension reinforcing pile 2, tie-beam 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, the U-shaped groove composite construction of high cantilever large span of the present utility model, comprise U-shaped groove structure 1, longitudinally tension reinforcing pile 2 is set the interval in the outside of this U-shaped groove structure 1, at the top of U-shaped groove structure 1 and tension reinforcing pile 2 fixed with it tie-beam 3 is set.The utility model utilizes tension reinforcing pile 2 for high cantilever U-shaped groove structure 1 provides stretching resistance, improves its structure stress, utilizes tie-beam 3 that tension reinforcing pile 2 stretching resistances are passed to U-shaped groove structure 1.This combining structure has effectively solved U-shaped groove structure and has improved the problems such as its structure stress and construction investment are large because stressed large, the span of high cantilever construction can't arrange stull in structural top greatly, its structural integrity is good, simple in structure, easy construction, construction investment economize, and meet environmental requirement, have wide popularizing application prospect.
Described tension reinforcing pile 2 vertical setting spaces are generally 5～10m, and are comprehensively more definite according to U-shaped groove structure 1 structure stress and economy.Described tension reinforcing pile 2 and U-shaped groove structure 1 lateral separation are generally greater than 1.5 times of U-shaped groove structure 1 cantilever height.
Some principles of the U-shaped groove composite construction of the high cantilever large span of the above the utility model that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
Claims (3)
1. the U-shaped groove composite construction of high cantilever large span, comprise U-shaped groove structure (1), it is characterized in that: the outside of described U-shaped groove structure (1) longitudinally interval arranges tension reinforcing pile (2), at the top of U-shaped groove structure (1) and tension reinforcing pile (2) fixed with it tie-beam (3) is set.
