Description
Technical field
The utility model is related to port and pier construction applications, and in particular to a kind of load retaining wall buttressed quay wall structure.
Background technology
Wharf structure must be adapted with geological conditions, otherwise can increase harbour cost, or even generate excessive position
It moves or settles, influence normal use.It is general more to rock, sand and harder cohesive soil ground (its internalfrictionangleφ is more than 25 °)
Using gravity-type structure, in shallow rock foundation, for big tonne of harbour according to traditional gravity-type structure, harbour bottom width is larger, builds
The cost for building object is larger；And the project that some rear plant areas are closer apart from wharf apron, to ensure construction period, harbour and land-based area
Facility is carried out at the same time, it is desirable that reducing when harbour foundation excavation influences the range of back-up land, also claims to harbour bottom width.
It can be seen that there is an urgent need to find a kind of structure, to meet bedding excavated volume as small as possible, and can pass through control structure
The mode of center of gravity controls bedding top surface stress distribution.

Specific implementation mode
In order to be better understood from the utility model, With reference to embodiment with attached drawing to the utility model into traveling
The description of one step.
As shown in Figure 1, a kind of load retaining wall buttressed quay wall structure of the utility model includes land-based area floor structure and is trapped among
Wharf apron outside land-based area floor structure.By Fig. 2 and Fig. 5 as it can be seen that wharf apron includes being connected by several transversely arranged counterforts
Made of buttress structure, the counterfort floor 2 that each counterfort is extended by counterfort riser 1, the self-support backboard towards extra large side towards land-based area
And the counterfort bottom plate 3 positioned at counterfort riser and counterfort floor bottom is constituted.In the middle part of floor or top flattened formation alar part backward
2.1, alar part forward downward is narrowed to counterfort bottom plate and is connect, and forms shape wide at the top and narrow at the bottom, and the horizontal top of alar part 2.1 is equipped with
The weight plate 4 being set up between adjacent counterfort floor.Counterfort weight plate 4 is located at 2 rear side top of counterfort floor, with counterfort floor 2
It is integral prefabricated.The effect of weight plate 4 is the reduction of soil pressure after wall, and is conducted oneself with dignity using filler more than weight plate, makes structure weight
It is moved after the heart, increases anti-square of going all out, so that foundation stress is evenly distributed, harbour bottom is minimized on the basis of ensureing structure safety
Width achievees the purpose that reduce and excavates range.
