A deep-water gravitation-type dock with drum-type base on soft foundation is composed of the base which is the drum without bottom plate and its inserted in the foundation, stinking caisson or cylinder on the top cover of said base, cover plate or unloading plate on the top of sinking caisson or cylinder, and breast wall on said cover plate or unloading plate. Its advantages are high durability and load bearing power.

Description

Bucket foundation gravitation-type deep-water dock structure on the soft foundation
Technical field
The present invention relates to the bucket foundation gravitation-type deep-water dock structure on a kind of soft foundation.Belong to the building structure in the port works field.
Background technology
Gravity type quay has good endurance, supporting capacity advantages of higher.At present, Gravity harf structure commonly used in the engineering has patterns such as caisson, counterfort, square, cylinder, and the gravity type quay of these structural shapes all needs good foundation and riprap foundation.Typical gravity caisson wharf such as Fig. 1 show, are made up of riprap foundation, caisson, relieving slab and breastwork.For the large-tonnage port berth on the soft foundation, build the gravity type quay of traditional structure pattern, then need to carry out foundation excavation, the foundation soil displacement of big section and build riprap foundation.Do like this, soil excavation and stemming operation amount are big on the one hand, particularly in the area that the sandstone material lacks, can increase construction costs significantly; On the other hand, under deep water, build the riprap foundation constructional difficulties, big as compacting, the leveling difficulty of riprap foundation, will inevitably cause the construction costs height; On the one hand, build gravitation-type deep-water dock on traditional riprap foundation again, also need satisfy antiskid and stability against overturning requirement, the width of structure must be big, and construction costs also can improve like this; The duration of building traditional gravity type quay in addition is also longer.Based on above-mentioned factor, on soft foundation, substantially all adopt the high pile pier structure pattern at present, show that as Fig. 2 typical long piled wharf is made up of the place ahead cushion cap and rear bearing platform, includes pile foundation, beam and plated construction in the cushion cap of front and back.Long piled wharf have poor durability, supporting capacity limited, to the very weakness such as sensitivity that overloads, and when on soft foundation, building the deepwater high pile harbour, because the requirement of stability of slope aspect, highrise pile cap will inevitably be more roomy, and the construction costs of deepwater high pile harbour also is quite high on the soft foundation like this.Therefore, in the time of on weak soil sea bed ground, building the deepwater wharf berth, need to adopt new dock structure pattern.
Summary of the invention
The object of the present invention is to provide a kind of bucket foundation Gravity harf structure that is applicable on the soft foundation, adopt the harbour of this structural shape to have the high superiority of good endurance, supporting capacity of traditional gravity type quay, have simultaneously easy construction, the characteristics that construction costs is relatively low again.
For achieving the above object, the present invention is realized by following technical proposals: the bucket foundation gravitation-type deep-water dock structure on the soft foundation is made up of basis, caisson or cylinder, cover plate or relieving slab, breastwork, it is characterized in that, the basis does not have the steel drum at the end for the top cover that has that is inserted in the sea bed foundation soil, but on its top cover or top barrel, be provided with the through hole of switch, drum diameter is 3.0m to 18.0m, the cylindrical shell height is 0.5 to 3.0 times of diameter, the thick 5mm to 30mm of lamina tecti and barrel is provided with deep floor at the lamina tecti downside; Caisson or cylinder are seated on the top cover of bucket foundation, and cover plate or relieving slab place the top of caisson or cylinder, and breastwork is positioned on cover plate or the relieving slab.
Superiority of the present invention is: the bucket foundation Gravity harf structure is suitable for building large-scale gravity type quay on weak soil sea bed ground, it has the high superiority of good endurance, supporting capacity of traditional gravity type quay, and easy construction, engineering cost is relatively low.
Description of drawings
Below in conjunction with accompanying drawing the present invention is illustrated.
Fig. 1 is a gravity caisson wharf structural representation.
Fig. 2 is the high pile pier structure schematic diagram.
Fig. 3 is a structure schematic cross-sectional view of the present invention.
1 is bucket foundation among the figure, 2 is caisson or cylinder, 3 is cover plate or relieving slab, and 4 is breastwork, and 5 is the harbour end face, 6 is waterline, 7 is former sea bottom surface, and 8 are the construction sea bottom surface behind the excavation, and 9 is sea bottom surface before the harbour, 10 are seabed weak soil layer and the line of demarcation that can hold the power soil layer, and 11 is the through hole on the cylinder-shaped foundation structure.
The specific embodiment
One embodiment of the invention is as follows: bucket foundation gravity type quay as shown in Figure 3, it is made up of bucket foundation, caisson, relieving slab, breastwork and other harbour ancillary facility.Caisson, relieving slab and breastwork are concrete structure, and for the ease of the installation of sinking, bucket foundation is a steel design.The harbour face top mark height that requires to build is+5.8m, seabed mud face absolute altitude before the harbour is-16.0m, require in view of the above and in conjunction with geological condition, the barrel diameter that can select the steel bucket foundation is 12.0m, high 12.0m, the thick 25mm of barrel, a bucket foundation top mark high position is in-10.0m place, and the barrel bottom is positioned at absolute altitude-22.0m place; Caisson bottom width 9.0m, high 11.0m, caisson are seated on the bucket foundation, and its top mark height is+1.0m; Off-load thickness of slab 1.0m, wide 12.0m; The high 3.8m of breastwork, bottom width 3.5m, top width 2.5m.
Adopt following process to build above-mentioned bucket foundation gravity type quay:
(1) prefabricated barrel basis, caisson and relieving slab member on land.
(2) the submarine surface weak soil is dug out the degree of depth, make the seabed of harbour construction place be horizontal plane to absolute altitude-10.0m.
(3) prefabricated cylinder-shaped foundation structure is transported to the location, installation place, employing vacuumizes and utilizes negative pressures that cylinder-shaped foundation structure is sunk, be inserted into to the barrel of cylinder-shaped foundation structure bottom and hold in the power soil layer, and the top cover of cylinder-shaped foundation structure and the interior native face of tube are contacted.After cylinder-shaped foundation structure sinks to putting in place,, make tight between the interior soil of cover and tube by the cementing mortar in tube of the through hole on cover and the barrel.After bucket foundation installs, just can excavate seafloor soil before the harbour to the degree of depth that requires (absolute altitude-16.0m).
(4) prefabricated caisson is installed on the top cover of bucket foundation, reinstalls earlier filler then in caisson, backfill and the consolidation process of carrying out the rear soft foundation are filled out in the back behind caisson.
(5) prefabricated relieving slab is installed on the caisson top.
(6) cast in situs breastwork.
(7) other harbour ancillary facility is installed and is built at backfill harbour rear.
The bucket foundation Gravity harf structure is suitable for building large-scale gravity type quay on weak soil sea bed ground.After adopting bucket foundation, do not need to carry out large cross section excavation and backfill, need not build riprap foundation, make the harbour easy construction.Bucket foundation is with soil body sealing in the tube, and its bottom reaches holds the power soil layer and certain buried depth is arranged, and makes that the vertical bearing capacity of dock structure and antiskid stability against overturning are satisfied.The bucket foundation Gravity harf structure has the high superiority of good endurance, supporting capacity of traditional gravity type quay, and its engineering cost is relatively low.
