Abstract
The present invention is one shoreside construction method. The construction process includes setting two rows of off shore pipe piles, setting one off shore dam before the sea bank in the sea bank direction, and setting one screen dike to connect the off shore dam and the available sea bank. The off shore dam has double row of pipe pile structure of single pile length 14-16 m, pile top elevation 0.8-1.2 m and pipe pile row interval 4.5-6 m. The outer screen dike outside the off shore dam is rubble filling structure. The present invention has high construction efficiency and high utility.
Description
One, technical field: the perforated pile offshore dike of pile tube engineering is reinforced a kind of foundation construction method of building field owned by France, relates generally to the job practices that the water surface, harbour and seashore etc. are located a kind of pile tube engineering.
Two, technical background: when carrying out basic engineering construction at the water surface, harbour or seashore, shallow sea place in the past, relate in particular to the construction of pile tube engineering, lack modern Work machine device, there is not advanced supporting corresponding plant equipment, often adopt in a large number and rely on artificial manual operations by the existing mechanical device that falls behind, its efficiency of construction benefit and safety are all lower, and the demand of incompatibility modernization construction fast development lags behind the development of whole building trade.
Three, summary of the invention: according to the defective of above existence, the perforated pile offshore dike reinforcing method that the purpose of this invention is to provide a kind of pile tube engineering, be double--rowed pipe pile to be set at original offshore dike place, mainly solve the new job practices of the transformation of the way, wherein change a social system new apparatus for work and adopt multinomial patented technology to advance a raising construction benefit.The present invention is 10 to 70 meters suitable one offshore dikes of sea wall direction setting in before existing sea wall levee toe, and separation levee is set one every 800 to 1200 meters, the offshore dike is connected with existing sea wall, the offshore dike adopts the double--rowed pipe pile structure, adopt diameter to be 450 to 550 millimeters and give the stress pile tube, its single pile length is 8 to 16 meters, stake top design height is 0.8 to 1.2 meter, the stake clear spacing is 25 to 35 centimetres, the double--rowed pipe pile center distance is 4.5 to 6 meters, and it is provided with separation levee three roads the offshore dike, and outer separation levee adopts the double--rowed pipe pile structure identical with the offshore embankment structure, interior separation levee adopts the jackstone dike to substitute the form of structure of double--rowed pipe pile dike, reduces the purpose of investing to reach.Key of the present invention is that the installation of pile tube is inserted and to be beaten, its construction technology is the pile tube system of giving, transport, carry out the seabed pipeline purging, the installation of pile tube is inserted and is beaten, to the pile tube outside jackstone is installed, at the inboard Nai Telong net of laying of pile tube, pile tube installed inside jackstone carries out articulated beam reinforcement construction and concrete construction then, carries out the jackstone construction of the interior outside of pile tube then and forms; It is that the stake top connects that pile tube wherein waterborne is inserted the installation step, the pile driving barge location, and concrete pile tube pile sinking to spud gantry is installed, staking out then, pile sinking is to the removal Pile feeder.
Main beneficial effect of the present invention is in constantly putting into practice, update making and settlement, the new civilized construction of initiative one cover, optimize operation, adopt new technology new material, the multinomial patent of new technology, cover sets the reinforcing method of the new pile tube engineering of system, improved construction and installation efficient and benefit, ensured safety construction, it is obvious to increase the wound economic benefit.
Four, embodiment: its detailed reinforcing method step of the present invention is a 1. construction lofting: according to given coordinate point, emit the center line control point of offshore dike double--rowed pipe pile and make sign at sea wall place sea wall platform, as jackstone Hu Tan position, offshore dike both sides.2. pipeline purging is felt the seabed along the pile tube axial location by professional diver, removes underwater obstacle, and 3. the stake top connects, and Pile feeder is connected on the bank with pile tube (patented product is all arranged), can adopt manually or mechanically screw connection.4. pile driving barge location: in the navigation system scope, bringing to, adjusting pile driving barge, the anchoring pile at four angles is fallen, a whole set of piling work program is implemented in the stable back of ship anchoring to job position; 5. locate concrete pile tube pile sinking; At oriented pile driving barge place, cooperate the vibrating hammer concrete pile tube location of slinging by crane, to locate the concrete pile tube at the place, both sides of pile tube axis slotting laying will be installed, the Height control of location concrete pile tube is exceeding 0.5 to 1.0 meter of pile tube design altitude, after the concrete pile tube is inserted and is got to the position, the cross-arm beam is installed on concrete pile tube top under the cooperation of crane again, the cross-arm beam adopts welding or screw connected mode with being connected of concrete pile tube, enter the construction of positioning framework location after the connection, 6. installing and locating framework (patented technology): at the pile driving barge place, positioning framework is sling, be installed in cross-arm Liang Chu with crane, positioning framework is fixedlyed connected with crossbeam, finish the installation of navigation system; 7. staking out: will connect Pile feeder (patented technology) pile tube one end and sling, break away from the deck after whole pile body is in vertical stable state, slowly install and insert in the hole, guide-localization frame (patented technology) stake position, pile tube slowly sinks under stake deadweight and tup effect, note correction at any time in the sinking process, guarantee pile tube axial location and verticality, when pile tube no longer sinks, finish the staking out process; 8. pile sinking: after the staking out, clamp Pile feeder with vibrating hammer pile tube is set upright, open vibrating hammer and implement the pile sinking operation.Rectify a deviation by the position of crane adjustment vibrating hammer in the pile driving process.When pile tube is sink to stable state, change the frequency conversion gear, full width is opened vibrating hammer and is implemented quick pile sinking operation.During end face, stop quick pile sinking operation on the nearly positioning framework of pile tube apical grafting, by the aftershock of vibrating hammer the pile tube pile sinking is put in place, vibration is carried out height of pile top after finishing, and detections such as axis reach standard, finish the pile sinking operation; 9. the removal Pile feeder is implemented the pile sinking operation of pushing ahead for the second time, but the pile tube that puts in place of pile sinking removal Pile feeder then carries out the lower whorl pile body and is connected with Pile feeder; The whole pile sinking of pile tube are finished in the guide-localization framework, on the direction of advance of construction, install again to insert and make a call to 2 location concrete pile tubes, the rear utilizes inserts two root canal piles of accomplishing fluently, the reach of slinging of guide-localization framework is fixing, the guide-localization pile frame is inserted the pile tube of accomplishing fluently and is adopted the sleeve connected mode with having installed, implement for the second time the whole pile tube pile sinking operation in the guide-localization framework, circulate with this and push ahead; 10. pile tube is connected and fixed: double--rowed pipe pile is that symmetrical construction is installed, and occurs the unexpected stake phenomenon of falling for preventing to insert the pile tube accomplished fluently because of wind wave action, after pile tube is inserted and beaten, must in time with reinforcing bar or angle steel pile tube be connected and fixed in length and breadth and form.Guarantee pile tube elevation unanimity, axis is straight, quality assurance.
