Abstract
The invention discloses a kind of steel pile casting formula deep-sea vibroflotation pile construction method, steps are as follows: (1) steel pile casting is squeezed into the following projected depth of sea bottom surface setting fixed pile position by the crane barge that is mounted on crane ship；(2) seawater inside steel pile casting is drained, and removes soil in steel pile casting；(3) vibrating impacter is put into steel pillar by crane barge, and drops to designated depth, sand, the close sand of later on vibrating impacter vibration are backfilled into steel pile casting；(4) steel pile casting and vibrating impacter are above mentioned simultaneously using crane barge, sand is constantly backfilled into steel pile casting, and it is close to shake paragraph by paragraph；(5) steel pillar and vibrating impacter aweigh face when stop backfill sand, and close vibrating impacter, complete stake process processed.Using the method, water-less environment can be created in profundal zone and constructed, prevented the fillers such as the sand of backfill from being washed away by water flow, substantially reduce the difficulty of construction for reinforcing profundal zone ground, increase construction stability.
Description
Technical field
The present invention relates to harbours and inshore engineering, hydraulic engineering and geotechnical engineering field more particularly to underwater to add
Gu field.
Background technique
Vibroflotation can be divided into vibrocompaction and vibroreplacement according to its difference for reinforcing object, and wherein the former mainly uses
The reinforcing of the coarse-grained soils such as Yu Zhong, coarse sand, and the latter is chiefly used in fine grain cohesive soil and reinforces.Sandy land is carried out using vibroflotation
Base processing, can not only improve foundation bearing capacity and deformation modulus, and can improve anti-seismic performance.Cohesive soil is carried out using vibroflotation
Basement process mainly forms the sand pile being relatively large in diameter in soil, and collectively constitutes composite foundation with the soil of surrounding.
The underwater on marine structure basis is reinforced usually relatively difficult.If carrying out dry operation using cofferdam method to apply
Work has the shortcomings that great in constructing amount, the construction time is long, deficiency in economic performance.If added using the ground that vibroflotation carries out cohesive soil
Gu being influenced by deep sea water, underwater borehole cleaning and sandy soil backfill washing away vulnerable to seawater, cause marine environmental pollution.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of steel pile casting formula deep-sea vibrosinking pile construction parties
Method greatly reduces the difficulty of construction for reinforcing profundal zone ground, reduces the investment of equipment and material, increases construction stability,
Improve construction efficiency.
The invention discloses a kind of steel pile casting formula deep-sea vibroflotation pile construction methods, the following steps are included:
(1) top of steel pile casting is connected with the first hawser, steel pile casting is setting fixed pile position insertion sea bottom surface to divide into
Depth is counted, steel pile casting installs spindle inclination and is not more than 1%, and crane barge is kept in the center after being detached from the first hawser；
(2) seawater inside steel pile casting is drained, and removes soil in steel pile casting；
(3) vibrating impacter is connected with the second hawser, and vibrating impacter is put into steel pillar by crane barge, and drops to specified deep
Degree backfills sand, the close sand of later on vibrating impacter vibration into steel pile casting；
(4) the first hawser is hung on crane barge again, above mentions steel pile casting and vibrating impacter simultaneously using crane barge, is constantly protected to steel
Sand is backfilled in cylinder, and it is close to shake paragraph by paragraph；
(5) steel pillar and vibrating impacter aweigh face when stop backfill sand, and close vibrating impacter, complete stake process processed.
Compared with prior art, present invention has the advantage that
Water-less environment is created in profundal zone using steel pile casting, and carries out underwater processing using vibroflotation.The technology can
Water-less environment is created in profundal zone by steel pile casting to construct, and is prevented the fillers such as the sand of backfill from being washed away by water flow, is dropped significantly
The low difficulty of construction for reinforcing profundal zone ground, reduces the investment of equipment and material, increases construction stability.Steel pile casting structure letter
It is single, it is easy to transport, weld, dismantle, may be reused.Meanwhile vibroflotation during simultaneously filled water mud, make itself and sand in cylinder
Soil is mixed to form rigid pile, can greatly improve foundation strength.In short, the technology reduces the difficulty of construction of deep water foundation stabilization,
Construction efficiency is improved, large-scale engineer application is easy to, there is very high engineering significance and application prospect.
Detailed description of the invention
Fig. 1 is steel pile casting deep-sea vibrosinking pile integral construction schematic diagram.
Fig. 2 is steel pile casting deep-sea vibrosinking pile work progress schematic diagram.
Specific embodiment
The present invention will be described in detail in the following with reference to the drawings and specific embodiments.
A kind of steel pile casting formula deep-sea vibroflotation pile construction method of the invention, comprising the following steps:
(1) top of steel pile casting 3 is connected with the first hawser 2, steel pile casting 3 is setting fixed pile position insertion sea bottom surface or less
(steel pile casting can sink to subsea level by self weight to projected depth, or can squeeze into sea by the piling machine being mounted on crane barge 1
Below bottom surface), steel pile casting installs spindle inclination and is not more than 1%, and crane barge 1 is kept in the center after being detached from the first hawser 2；See Fig. 2
In step 1. and 2.；Projected depth need to according to practical soil layer situation determine, and guarantee steel pile casting have enough stability and
Seawater cannot be flowed into inside casing by bottom；
(2) seawater inside steel pile casting is drained, and removes soil in steel pile casting, see step in Fig. 2 3.；
(3) vibrating impacter 4 is connected with the second hawser 5, vibrating impacter 4 is put into steel pillar 3 by crane barge 1, and drop to finger
Depthkeeping degree backfills sand into steel pile casting using forklift or other machines, and later on vibrating impacter 4 shakes close sand, sees in Fig. 2
Step is 4.；When backfilling sand, the fillers such as cement and water can be optionally added, form vibroflotation cement rigid pile.
(4) the first hawser 2 is hung over again on crane barge 1, above mentions steel pile casting 3 and vibrating impacter 4 simultaneously using crane barge 1, constantly
Sand is backfilled into steel pillar, and it is close to shake paragraph by paragraph.See that step is 5. in Fig. 2；
(5) steel pillar and vibrating impacter aweigh face when stop backfill sand, and close vibrating impacter, complete stake process processed,
As in Fig. 2 step 6. and 7. shown in.
Preferred steel pile casting should have lifting lug so as to connect with hawser carry out decentralization and on pull out, steel pile casting top surface is more than sea level
The above 0.5-1.0m is advisable.It can be convenient steel pile casting indentation in this way and extract, and guarantee not have after steel pile casting squeezes into sea bed
Seawater above steel pile casting by entering, to ensure the water-less environment in casing.
