Description
Technical field
The present invention is a kind of method for designing of harbour structure, belongs to port works and hydraulic engineering technical field.
Technical background
The caisson gravity type quay is a kind of of Gravity harf structure, and dock wall has adopted the caisset pattern.Traditional caisson type harbour is to rely on the own wt of caisson and the bearing capacity of caisson bottom surface ground to safeguard caisson and connect bank stability of structure and function of use.
The harbour caisson of China adopts steel or steel concrete to make thin-walled, on an empty stomach bottom structure is arranged more, after caisson is in place at the scene, fills the sand material that meets certain requirements in the caisson empty stomach, and the case back of the body bankets and adopts piece stone, rubble or hydraulic fill sand.In order to resist the horizontal loading that the case back of the body bankets and the effect of dynamic loading, the caisson bottom should have enough width that skid resistance and moment are provided.Therefore, it is big that traditional caisset has planar dimension, the characteristics that monomer weight is big.
General caisson gravity type quay ground all with the natural top layer bearing capacity of foundation soil below the structure bottom surface as bearing stratum.Do not reach bearing capacity of foundation soil for the moment and down hard formation for sleeping in is embedding when dark at structure bottom surface ground, can adopt cushion (jackstone displacement etc.) or be transformed into the composite foundation method and solve.If have deep soft soil under the absolute altitude at the bottom of the caisson, and down hard formation for sleeping in is embedding when dark, needs to adopt ground to handle, with bearing capacity and the settlement request that satisfies dock structure.And China's coastal port harbour is depositing deep weak soil layer mostly, so need carry out treatment of soft foundation usually at the bottom of the caisson.The typical caisson Gravity harf structure of China as shown in Figure 1.
From traditional caisson type harbour design worker method analysis as can be seen, there is following some limitation in the gravity caisson wharf:
(1) in order to resist the effect of dynamic loadings such as horizontal earth pressure that the case back of the body bankets and wave force, the caisson bottom should have enough width that skid resistance and moment are provided, therefore the width of caisson is often bigger, weight is heavier, it is also bigger that sink-box load influences the degree of depth, the soft basic scope (width and the degree of depth) that causes needing below the caisson bottom surface to handle also increases thereupon, thereby has increased the construction costs of treatment of soft foundation, and the increasing of the degree of depth of treatment of soft foundation has simultaneously also increased intractability;
(2) caisson fills behind needs a large amount of building stones, and this need solve by the massif around the exploitation, has both influenced the ecological environment of massif, and the severe of building stones has strengthened the difficulty that ground is handled greatly again;
(3) produce a large amount of dredging silts in the caisson gravity type quay construction process, the mud dredging needs certain expense, also can influence surrounding enviroment.If handle utilization again to abandoning mud, not only can save a large amount of sandstone material but also can protect environment.
Summary of the invention
Technical problem: the present invention proposes to adopt box-depositing dock light quantization, the dredging silt of engineering site is carried out lightweight handle, and has construction costs, advantages such as reduction of erection time and twice laid.
Technical scheme: the present invention is on the basis of analyzing existing caisson gravity type quay structure, makes improvements.So-called box-depositing dock light quantization, utilize a large amount of dredging silts that produce in the harbour build process exactly, generate light soil with cement and light weight agent (as bubble, foam beads, damaged tire fragment etc.), replace the stone material and the sand material that fill in caisson behind and the caisson empty stomach.Can turn waste into wealth on the one hand, to regenerations such as dredging silt, damaged tire fragments, the protection environment; On the other hand, utilize the less proportion 1.1～1.2g/cm of light soil
3, consider the influence of buoyancy in the water, the light soil severe of underwater placement must not be less than 1.0g/cm
3The minimizing caisson bankets behind to the weight of the horizontal force of caisson and the on an empty stomach interior filling material of caisson, reduce caisson size and weight, make things convenient for the operation such as transportation by driving, installation of caisson, reduce the influence basin of sink-box load simultaneously, thereby reduce treatment of soft foundation scope under the caisson accordingly, reduce engineering quantity, reduction of erection time, save construction costs.Therefore caisson type harbour light weight chemical industry method is a kind of effective harbour structure method for designing, has tangible economic benefit, environmental benefit and social benefit.
Concrete method is:
1). at the port berth place caisson and caisson rear are thrown the mud sucking-off of filling out the place;
2). with the mud of sucking-off by hydraulic suction dredge or refute and deliver to that cement is added in the place, rear and the foaming agent material stirs into the light soil material;
3). the basic unit of levelling caisson bottom, transportation by driving and installation caisson;
4). after caisson was installed, light soil was filled out in throwing at the caisson rear, and filled the light soil that stirs after forming in the caisson empty stomach, and carried out grinding compacting;
5). the miscellaneous part of fitting-out quay comprises mooring dolphin etc.
Beneficial effect: the advantage of caisson type harbour light weight chemical industry method be mainly reflected in following some:
(1) caisson type harbour light weight chemical industry method makes full use of the dredging silt of engineering site, turn waste into wealth, reduced the secondary environmental pollution that abandoning of dredging silt put and Transportation Engineering causes, the light soil that utilizes dredging silt, cement and light weight agent to prepare simultaneously fills caisson and bankets behind and in the caisson empty stomach, save a large amount of stone materials and sand material, walked the road of recycling economy;
(2) severe of light soil only is 1.1～1.2g/cm much smaller than stone material and sand material
3(consider the influence of buoyancy in the water, the light soil severe of underwater placement must not be less than 1.0g/cm
3), therefore, light soil acts on horizontal loading on the caisson and the caisson weight of banketing on an empty stomach will significantly be reduced, caisson size and weight can obviously reduce, and therefore, the soft basic scope that needs under the caisson to handle obviously reduces, reduced workload, shorten the construction period, saved the cost of caisson, made things convenient for the operations such as transportation by driving, installation of caisson simultaneously;
(3) caisson type harbour light weight chemical industry method has the certain economic effect.Reduce treatment of soft foundation scope under the caisson, reduced workload, can save construction costs; Save the processing and the freight thereof of dredging silt; Reduction of erection time, can bring into play the effect of harbour as early as possible; Need consume certain cement and light weight agent even consider the lightweight of dredging silt, compare the deep soft foundation of large-scale caisson bottom surface and handle, still can save construction costs, have environmental effect and social effect preferably simultaneously.
