Description

A kind of device and construction method setting filling bag based on enclosed waters location bank of tubes
Technical field
The invention belongs to position bank of tubes and set filling bag technique field, particularly relate to a kind of based on enclosed waters positioning pipe Row sets device and the construction method of filling bag.
Background technology
Along with the progress of national economy, reclamation engineering gradually rises in recent years, has huge society and warp Ji benefit.Such as in reclaiming land around sea is planned, often occur in enclosed waters and set every low bank between fields similar for convenience of later stage hydraulic reclamation etc. Situation.
In filling bag encloses low bank between fields project under construction, blast ship often has the function of station keeping ship concurrently, is used for positioning and expanding filling Bag.But under some water area conditions, blast ship cannot realize drawing location in levee body both sides due to a variety of causes, it is impossible to has assisted The location becoming filling bag expands operation, need to complete construction task by the location boats and ships of interim handling, increase and set accordingly Standby input, construction cost is higher than conventional construction mode.The present invention uses location bank of tubes to expand the construction method of filling bag, in nothing Complete filling bag under conditions of needing station keeping ship expands positioning operation, decreases the input of ship machine equipment, has saved correlative charges.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of construction convenient, workable, have Effect solve the equipment such as blast ship cannot enclosed waters have concurrently station keeping ship implement operation a difficult problem based on enclosed waters position Bank of tubes sets device and the construction method of filling bag.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
A kind of device setting filling bag based on enclosed waters location bank of tubes, it is characterised in that: include filling bag levee body two Two groups of location bank of tubes that side is parallel, the location anchor of fixing both sides bank of tubes, fixed pulley fixing on the bank of tubes of both sides, three pvc pipes are logical Crossing pipe collar and connect into bank of tubes, filling bag corner is connected with fixed pulley on bank of tubes by hawser, and hawser draws filling bag by fixed pulley Corner launch, sand ship carries out blast by Flat boat and sets filling bag.
The present invention also provides for a kind of construction method setting filling bag based on enclosed waters location bank of tubes,
(1) preparation of construction;
(2) measurement and positioning: measure construction area actual depth of water situation, measures the levee body axis of construction area and puts Sample.
(3) Flat boat location: handling Flat boat, location anchor are to waters of constructing;
(4) connect hydraulic reclamation pipeline: connection blast pipeline is in place and casts anchor fixing, puts the diverter valve of tube head in order, connect Blast ship and the marine interface of pipeline, and pipeline is blown water test.
(5) location bank of tubes is connected: bank of tubes is assembled side by side by blast plastic tube and forms, for ensureing the integral rigidity of bank of tubes Its width should be more than 2 rows, and bank of tubes length determines according to filling bag longitudinal size, are generally 80~120m, if passing through Increase bank of tubes connecting length increasing boundary of works area and can add throwing location anchor in bank of tubes centre position.
(6) fixed pulley is connected: fixed pulley is connected to the fixed position of anchor hawser on bank of tubes, it is to avoid bank of tubes is when stretched-filled bag Produce moment, both sides bank of tubes should be laid four fixed pulleys with stretched-filled bag corner.
(7) cast anchor fixing:
A, every bank of tubes at least want impelling two mouthfuls anchoring fixed, and anchor stern fast a length of 90~150m, bank of tubes end hawser is fixed on On the adpting flange of bank of tubes (usually first flange-interface), anchor hawser and dike axis angle control at 35 °~55 °, two pipes Registration anchor should be arranged symmetrically with, and bank of tubes spacing is more than maximum filling bag width 35~50m.
B, bank of tubes away from and the determination of pulley position finally should ensure that filling bag bag angle draw direction and dike axis angle exist 30 °~60 °.
(8) filling bag corner fixed by rope: during connection, (restrict without using during binding strap through the binding strap at bag angle in rope one end Rope colligation), setting fastening position is regained as far as possible, can untie smoothly after fixing to facilitate filling bag to sink.The other end of rope is fixed on On ship, filling bag corner and rope colligation successively are fixed.
(9) water under filling bag: manpower is pullled flat board and blown two bag angles of side, opposite, and two ropes additionally are put accordingly Pine, filling bag gradually descends water under the traction of rope and launches, and the position adjusting filling bag makes its sideline parallel with levee body axis, When two bag angles stop stretching to when exceeding construction sideline 1~2m, and rope ends on ship is fixed, can be when there being water outlet section Operate on water outlet filling bag.
(10) location adjusts: tighten up the rope at two other bag of angle with anchor capstan, and rope is distinguished with anchor capstan after tightening up again Filling bag corner is adjusted, makes filling bag transverse direction and longitudinal direction position meet it is expected that be fixed on by four ropes after completing On the position specified.
(11) filling bag cuff is laid: by manpower traction's flexible pipe to filling cuff position, flexible pipe stretches into cuff about 1; 5m, with tightrope knot that can be undone by a pull colligation, solution end of thread stays long and is cursory, it is ensured that filling bag can be untied knot that can be undone by a pull smoothly after sinking and extract flexible pipe.
(12) filling is sunk:
A, turn on pump fill sand, and slush pump should be opened one by one, and current gradually step up suction sand concentration after arriving diverter valve.During filling First corner location to bag should fill sand, sand flexible pipe, towards being directed at four angle points, makes filling bag corner uniform force, Ensure the state keeping launching when filling bag sinks, should progressively payout when filling bag sinks.
B, filling bag adjust filling cuff in time according to loading time after sinking, it is ensured that filling bag uniformly fill sand.
(13) stationary rope is untied: after filling bag is fixing, payout, follows to the slip-knot of bag angle along rope with little raft, connects Lower rope also draws to ship standby.
The present invention has the advantage that with good effect: construction technology of the present invention is easy, workable, efficiently solves The equipment such as blast ship cannot be greatly saved simultaneously be constructed in levee body both sides to the difficult problem drawing location to set filling bag operation This.This type of construction method setting filling bag fully demonstrates exploitativeness and economy by case history.
