Description
Technical field
It the utility model is related to water conservancy construction technical field, and in particular to a kind of buttress structure.
Background technology
Gravity type buttress structure on the water be used widely by engineering.Gravity harf structure after wall body, bedding, wall by filling out
Material composition, wall body are made up of breastwork and wall body block.Gravity type quay have structural shape it is simple, it is easy for construction, using adaptation
Property it is strong, build the features such as low with maintenance cost, Gravity harf structure is widely used on preferable ground.Counterfort code
Header structure has simple in construction, and speed of application is fast, and the advantages that low cost, but buttressed quay wall globality is poor, construction stability compared with
Difference；Soil pressure is excessive after wall may result in the larger even more than allowable bearing capacity of foundation soil of front toe stress.Caisson wharf structure phase
Preferable than buttressed quay wall structure stress situation, geostatic shield is uniform after wall, and caisson wharf overall performance is good, but caisson needs
Precasting yard is carried out prefabricated by land, and by ship haul, it is necessary to which large-scale construction equipment, execution conditions are with requiring higher.With
Maximization, the development trend of deep water, the buttress type harbour soil huge by rear side is born just is being presented in economic fast development, harbour
Pressure, traditional buttress type structure are difficult to meet that the wharf apron depth of water increased dramatically caused rear side soil pressure requirement.
Utility model content
The utility model is poor for traditional buttress type structural integrity, it is difficult to meets that the wharf apron depth of water increased dramatically production
Raw rear side soil pressure requirement, the shortcomings that to overcome buttress structure antetheca structural strength weaker, there is provided one kind can improve gravity type
The arc buttress type structure of the seismic stability of buttressed quay wall.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：A kind of arc buttress type structure, it is special
Sign is：Include counterfort bottom plate, counterfort side wall and arc counterfort antetheca, counterfort side wall and arc counterfort antetheca are solid vertically together
Due on counterfort bottom plate, arc counterfort antetheca butts up against the front end of two counterfort side walls；The arc counterfort antetheca is arcuate structure,
Its arc evagination forward-facing protrudes；The intrados of arc counterfort antetheca is placed with vertical ribs, and each vertical ribs is from arc
The inner arc backward-facing protrusion of counterfort antetheca.
Further, some horizontal ribs are additionally provided between adjacent vertical ribs, horizontal ribs is connected to
The intrados of arc counterfort antetheca, its both ends and the side vertical connection of adjacent two vertical ribs are formed to arc counterfort antetheca
And the ruggedized construction of vertical ribs.Horizontal ribs and vertical ribs on counterfort antetheca can improve the intensity of antetheca, subtract
Small anterior wall thickness, reduce cost.
Further, concavo-convex alternate flange and recess are respectively arranged on the left side and the right side in counterfort bottom plate, be disposed adjacent
Two counterforts are mutually twisted to form integrated connection fixed structure by the flange of a counterfort bottom plate and the recess of another counterfort bottom plate, this
Sample can reach more firm connection, improve the resistance to overturning of adjacent buttress structure, and improve the anti-seismic performance of structure.Together
It can be set between Shi Xianglin buttress structures and fall to consider structure, prevent from returning packing leaking on rear side of buttress structure.
Further, the arc counterfort antetheca is semi-cylindrical shaped structure, and its preceding surface is smooth cylindrical surface, and arc
The rear end of shape counterfort antetheca connects as one structure with the front end of counterfort side wall.Semicylindrical counterfort antetheca make overall structure by
Power is more reasonable.
Further, whole buttress structure is precast construction (such as precast concrete), the arc counterfort antetheca it is straight
Footpath is 5~10m.
Further, the height of the vertical ribs and the arc counterfort antetheca is elongated, the section of vertical ribs
The length of side is 20~30cm, and the adjacent vertical angle for strengthening intercostal is 10~30 degree, and vertical ribs is with arc counterfort antetheca
Integrative-structure.
Further, horizontal ribs is arranged in the inner side of arc counterfort antetheca, and it is in the arcuate structure of 180 degree, section
The length of side is 20~30cm, and the distance that adjacent transverse strengthens intercostal is 1~5m, and horizontal ribs is helped with vertical ribs and arc
Wall antetheca is structure as a whole, and forms an entirety, greatly improves structural strength.
The utility model is by the use of the vertical and horizontal ribs of semi-cylindrical shaped respective outer side edges as counterfort antetheca, and the structure is based on the power of face
And bending stress is smaller, stress condition is good, more saves material usage；Simultaneously using the erose structure of bottom plate both sides so that
Adjacent buttress structure is mutually twisted, the globality of enhancing structure, improves seismic stability, reduces harbour horizontal displacement, and general
Logical counterfort is compared, and is more suitable for deepwater wharf, while can reduce size with structure, improves harbour using effect；In existing gravity
, can be more by improving buttress structure moulding gravity type buttressed quay wall structure in the case that formula buttressed quay wall construction is constant
Self structure characteristic is played to big degree, deepwater wharf structure is more suitable for, there is positive social benefit and huge economy
Benefit.
