Abstract
The utility model provides a bank protection structure for a caisson wharf, whcih comprises a caisson, a foundation bed, a breast wall and fillers. A caisson with an inclined bottom surface can be mounted on a horizontal foundation bed; or, a common caisson can be mounted on a foundation bed inclined backwards; or, the caisson with the inclined bottom surface can be mounted on a foundation bed inclined backwards, wherein the inclination of the caisson is higher than 4%, thus tilting the rear wall of the caisson backwards and forming the bank protection structure for the caisson wharf inclined backwards. The utility model can reduce the soil pressure, improve the stability of the caisson structure, ensure the reasonable stress of the foundation bed and reduce the risk of the accidental crash of ships; and the rear rails of the portal crane can be mounted on the caisson under the specific conditions, so as to reduce the deformation caused by the difference between the front rail and rear rail of the portal crane.
Description
Affiliated technical field
The utility model relates to a kind of caisson wharf bank protection structure.
Background technology
The caisson wharf bank protection structure, that mainly utilizes structure realizes antiskid, stability against over turning from gravity.Common caisson wharf or shore protection, caisson are on the bedding of the level that vertically is placed in.About 1～the 1.5m of toe length before the caisson antetheca leaving wharf frontal line 0.3～0.5m, caisson.For adapting to the harbour sedimentation and deformation, bedding is generally reserved adverse slope about 0.3～1%.
Common caisson wharf bank protection structure, soil pressure is bigger, and rail is seated in the caisson back sometimes behind the door machine, and bigger to the soil pressure of caisson sidewall, front and back differential rail sedimentation is big.Through research and analysis, find under these specified conditions, vertical caisson antetheca and rear wall to be set to the hypsokinesis certain angle, form the caisson wharf bank protection structure of hypsokinesis.
Realize the hypsokinesis of caisson, 3 kinds of approach are arranged.The one, the caisson that adopts the bottom surface to tilt is installed on the bedding of level and forms hypsokinesis; The 2nd, adopt common caisson, be installed on the bedding of hypsokinesis and form hypsokinesis; The 3rd, adopt above-mentioned 2 kinds of measures simultaneously, the caisson that promptly adopts the bottom surface to tilt is installed on the bedding of hypsokinesis, realizes bigger hypsokinesis angle.The hypsokinesis gradient of above-mentioned caisson is greater than 4%, and the gradient about 1% of reserving sedimentation and deformation with the harbour bedding is different.
The caisson wharf bank protection structure of hypsokinesis has the following advantages.
1 reduces soil pressure, and it is rationally stressed to increase structural stability and bedding.The caisson wharf structure of hypsokinesis, the one, the harbour wall inclines behind and helps reducing the horizontal earth pressure of the wall back of the body; The 2nd, the center of gravity of caisson and filler moves along with the hypsokinesis of caisson backward, helps increasing the reasonable distribution of the stability against overturning and the bedding stress of structure; The 3rd, caisson hypsokinesis breastwork and fender are outstanding, and caisson top antetheca leaving wharf frontal line is farther, helps reducing the risk of boats and ships accidental impact caisson.
2 help rail behind the door machine is arranged on and reduce relative settlement on the caisson.Under the situation of the about 1.5m of rail next-door neighbour's caisson rear wall behind the door machine of vertical caisson wharf, then needn't widen caisson, as long as the suitable angle of caisson hypsokinesis, just rail behind the door machine can be arranged on the caisson, help reducing the differential displacement of the forward and backward track of machine and a sedimentation, and avoid or reduce the soil pressure of back rail wheel load generation.
3 improve opposing wave suction.For being the shore protection of control with wave suction, the perhaps harbour that is dominant of the relative soil pressure of wave suction, in structure by block along under the situation of bedding end face antiskid control, adopt the hypsokinesis structure, can effectively improve the skid resistance of structure, thereby reduce the engineering quantity of structure.
Generally speaking, the weight of the filler on the caisson top that the harbour hypsokinesis increases, the weight of the part filler that reduces with the forward position is suitable substantially.The construction equipment and the technical strength of marine traffic engineering are very strong at present, and caisson or bedding hypsokinesis have exploitativeness.But in prefabricated, the transportation of inclination caisson with install, the aspect construction such as fill out, closely knit in the throwing of inclination bedding higher than the construction requirement of common caisset and bedding, needs to increase some costs in the construction.Under given conditions, the overall benefit of hypsokinesis caisson is good.
Summary of the invention
In order to reduce the soil pressure of caisson rear wall, help behind the machine rail be arranged on reduce on the caisson before and after the differential rail distortion, improve structural stability and improve bedding stressed, reduce caisson by the risk of boats and ships accidental impact, the utility model provides a kind of caisson wharf bank protection structure, to optimize common caisson wharf bank protection structure.
In order to achieve the above object, the technical solution used in the present invention is that the caisson that adopts the bottom surface to tilt is installed on the bedding of level, or adopt common caisson to be installed on the bedding of hypsokinesis, or the caisson that adopts the bottom surface to tilt is installed on the bedding of hypsokinesis, realize the hypsokinesis of caisson rear wall thus, form the caisson wharf bank protection structure of hypsokinesis.The hypsokinesis gradient of caisson is greater than 4%.
After adopting caisson wharf bank protection structure of the present invention, soil pressure reduces, and structural stability improves, and bedding is stressed rationally, reduce caisson by boats and ships accidental impact risk, rail can be installed on the caisson to reduce a differential deformation of machine front and back track behind the machine of specified conditions Xiamen.
The beneficial effects of the utility model, soil pressure reduces, and structure and bedding are stressed rationally, and track reduces caisson by the risk of boats and ships accidental impact to reduce relative settlement after helping a machine is installed, and comprehensive benefit is good on the whole.
