Description
Technical field
The invention belongs to technical field of construction, it is related to a kind of filling out to go along with sb. to guard him and synchronous carry out construction method for dredge fill.
Background technology
Traditional strand inhales ship dredging and reclamation construction method, is first to specify to need to form the region of land-based area in design, using throwing
Stone, sand filling bag, the method such as banket form a cofferdam for closing in its surrounding, then lay hydraulic reclamation pipeline and are inhaled ship and excavated by twisting
Dredging markets after moisture is drained, form land-based area using in waterpower hydraulic reclamation to the closing cofferdam by the native stone for leaving.But entering
During row offshore off-lying sea man-made island engineering construction, construction area periphery is all without enough or at all with regard to no soil sand building stones for closing
Cofferdam is filled, and such engineering is away from inland, if carry out cofferdam construction from inland transport soil sand building stones, not only serious shadow
Construction speed is rung, and the construction cost of engineering can be greatly improved.
The content of the invention
Deficiency it is an object of the invention to be directed to existing construction method, there is provided one kind is that sandstone etc. is difficult in face of dredging markets
During the soil property of loss, can effectively improve efficiency of construction and make full use of field resources and reduce engineering cost for hydraulic reclamation
The filling out of construction is gone along with sb. to guard him and synchronous carries out construction method.
To achieve these goals, present invention employs following technical scheme：
A kind of filling out to go along with sb. to guard him and synchronous carry out construction method for dredge fill, it is characterised in that：The method is comprised the following steps：
（1）Operating reserves：
Water-depth measurement is carried out to construction area, it is determined that twist inhaling ship stationary point position；
Scene carries out drill hole sampling to geology, determines soil property situation；
According to soil property situation, it is determined that the slope ratio for inhaling ship hydraulic reclamation into beach is twisted, with reference to hydraulic reclamation height and the bounds of formation land-based area, meter
The position that cofferdam should lay is calculated, quantity and the position of line layout is determined therefrom that；
（2）Twist and inhale ship hydraulic reclamation
After completing above-mentioned line layout, strand suction ship is marched into the arena and carries out dredge fill；
Height of beach to be formed exceedes mean high water level (M.H.W.L.) 1m, and beach toe exceedes design cofferdam outward flange 1m, you can opened
Open up the construction in cofferdam；
（3）Cofferdam construction
Mechanized construction is carried out using the section construction of Temporary Cofferdam；
The construction in cofferdam will be configured with reference to the axis trend of permanent shore protection to greatest extent, it is to avoid the trouble of Secondary Transport；
Simultaneously cofferdam construction progress all the time main points prior to cofferdam into beach progress；
（4）The protection in cofferdam
Should be in one layer of anti-aging geotextiles of cofferdam bedding after the completion of cofferdam, it is to avoid the common geotextiles for cofferdam construction receive illumination
Occur aging；Using concrete geotextile tube bag protection lateral surface, it is to avoid washed away by stormy waves by cofferdam.
Further, described step（2）Detection is carried out during suction ship hydraulic reclamation is twisted, the beach formed to hydraulic reclamation
The ground gradient is measured, and is then contrasted with former design value, to be corrected in good time in the case where there is gap；
According to design hydraulic reclamation absolute altitude and with reference to actual hydraulic reclamation settling amount, outlet spout beach face elevation control is adjusted, can be effective
Ensure the flatness of hydraulic reclamation and control earthwork balance.
Further, described step（3）Middle cofferdam construction progress all the time main points prior to cofferdam into beach progress, it is desirable to
Cofferdam length growth is faster than beach and forms 70-130m.The loss of hydraulic reclamation can so be reduced and the efficiency of synchronous construction is improved.
Beneficial effects of the present invention：
The present invention inhales ship dredge fill synchronization for the soil property that dredging markets are that sandstone etc. is not easily runed off using by cofferdam construction and strand
Carry out, can effectively solve the problems, such as that construction area cofferdam filler is deficient, and effectively improve efficiency of construction and fully profit
Engineering cost is reduced with field resources.
Brief description of the drawings
Fig. 1 is using the site operation figure of construction method of the present invention.
Identified in figure：1- is twisted and is inhaled ship, the cofferdam of 2- constructions, the beach of 3- formation, cofferdam, the 5- mouths of pipe of 4- designs.
Specific embodiment
It is described in further detail to specific embodiment of the invention below.
A kind of filling out to go along with sb. to guard him and synchronous carry out construction method for dredge fill, it is characterised in that：The method includes following step
Suddenly：
（1）Operating reserves：
Water-depth measurement is carried out to construction area, it is determined that twist inhaling ship stationary point position；
Scene carries out drill hole sampling to geology, determines soil property situation；
According to soil property situation, it is determined that the slope ratio for inhaling ship hydraulic reclamation into beach is twisted, with reference to hydraulic reclamation height and the bounds of formation land-based area, meter
The position that cofferdam should lay is calculated, quantity and the position of line layout is determined therefrom that；Hydraulic reclamation shaping is set according to different great soil groups
The ratio of slope on beach, such as following table：
| Great soil group | The ratio of slope |
| Mud, silt | 1:100~1:300 |
| Fine sand | 1:50~1:100 |
| Middle sand | 1:25~1:50 |
| Coarse sand | 1:10~1:25 |
| Gravel | 1:5-1:10 |
（2）Twist and inhale ship hydraulic reclamation
After completing above-mentioned line layout, strand suction ship is marched into the arena and carries out dredge fill；
Height of beach to be formed exceedes mean high water level (M.H.W.L.) 1m, and beach toe exceedes design cofferdam outward flange 1m, you can opened
Open up the construction in cofferdam；
（3）Cofferdam construction
Mechanized construction is carried out using the section construction of Temporary Cofferdam；
The construction in cofferdam will be configured with reference to the axis trend of permanent shore protection to greatest extent, it is to avoid the trouble of Secondary Transport；
