Abstract
The present invention relates to a construction method for cofferdam dams, which belongs to the technical field of hydraulic engineering. The present invention comprises: chemical fiber weaved cloth and earth materials are used as materials; first, the chemical fiber weaved cloth is sewn into cloth bags, each of which is provided with a mud conveying pipe inlet; the cloth bags are laid in predetermined positions, slurry is filled into the cloth bags by a slurry conveying machine, the slurry in the cloth bags is precipitated, and after soil in the cloth bags is consolidated, a sand bag cofferdam dam is formed; the cloth bags can be made into various specifications of cloth bags, and beach land soil can be used, or a navigation channel can be dredged for getting soil from a near place. The present invention has the advantages of advanced technology, quick construction progress and low cost.
Description
The present invention relates to the job practices of piling up of earth dam engineerings such as sea wall, river enclose, dam, river, belong to the hydraulic engineering technical field.
Traditional cofferdam damming method; be to throw with piece stone, straw bag soil, woven bag soil, the soil that looses etc. to fill out, pile up, existing job practices is owing to use piece stone, earth material; often be subjected to the restriction of resource; way far away carrying, time-consuming, the cost height; construction speed is slow; stock utilization is low, and cofferdam, dykes and dams internal pore are bigger, piping and the native phenomenon of stream occur and causes that cofferdam, dyke (dam) are local to take place and cave in through regular meeting.There is the space in cofferdam, the dyke (dam), also increased certain degree of difficulty for the construction of holding one's breath after damming.
The objective of the invention is to provide a kind of and draw materials conveniently, speed of application is fast, the job practices of the measured confferdam and dyke-dam of confferdam and dyke-dam matter.
The object of the present invention is achieved like this, with chemical fibre woven cloth and earth material is material, earlier the chemical fibre woven cloth is sewn into the cloth bag of dredging tube inlet, behind cloth bag laying location, in cloth bag, charge mud by the bag gradation, be full of earth material in the cloth bag and be consolidated into the sand pocket confferdam and dyke-dam.For example build sea wall Jiang Xu on the ground, the cloth bag of making is laid on the bottom surface of sea wall Jiang Xu, adopt slurry transportation machinery in bag, to charge mud, when the bag internal pressure is born pressure near allowing of cloth bag, transfer to dredging tube, discharge from the woven cloth eye in part water body in the bag, bag continues to charge mud after internal pressure reduces again in bag, wait charge several times after, earth material is full of soil solidifying substantially in the bag.Cloth bag can be made all size as required, can be a cloth bag, also can be that many cloth bags layings are joined, can also be that one, two or many phases are laid side by side, after these cloth bags were full of sludge consolidating, earth material and bag were all very tight with the bag joint in the bag, just constitute the sea wall river and enclose.
Said cloth bag being laid the location, is successively to lay the location cloth bag, charges mud by a bag gradation in bag, treat down one deck cloth bag be full of earth material fixed after, repave the last layer cloth bag and in bag, charge mud, successively increase, the multilayer bond becomes cofferdam, dykes and dams.At 2 meters during, in confferdam and dyke-dam footing sideline fixedly cloth bag of a bar is set for the depth of water in advance with interior subaqueous construction.Gradation charges mud in bag, be meant when in bag, charging mud at every turn, when the bag internal pressure is born pressure near allowing of cloth bag, temporarily stop in bag, to charge mud, discharge from the woven cloth eye in part water body in the bag, the soil body is fixed gradually, after the bag internal pressure reduces, continues to charge mud again in bag.So-called multilayer bond is meant the cloth bag bond that is full of earth material more than 2 layers.With chemical fibre woven cloth and earth material is the job practices of material confferdam and dyke-dam, the cloth bag that the dredging tube inlet is arranged that also can be earlier be sewn into the chemical fibre woven cloth, on the water surface, lay and charge mud, throw when fixed and fill out under water Deng soil body part in the cloth bag, after waiting to throw confferdam and dyke-dam that the sand pocket filled out forms and surfacing, on sand pocket, lay cloth bag again, charge mud, successively increase the bond confferdam and dyke-dam.This deep water is thrown and is filled out job practices, and the general depth of water is utilized workboat or working platform during greater than 2 meters, after on workboat or the working platform cloth bag having been charged mud, throws and fills out estimating position.The way that throwing is filled out can be provided with chute on workboat, platform, allow sand pocket slide water and to go from ship, platform, also can use boom hoisting, after sand pocket is sling, puts down water and goes.
Technology advanced person of the present invention, the operation construction is simple, short construction period, small investment, reliable in quality reduces the dam body internal pore, improves the compactness in the dam body, saves piece stone, reduces freight volume.Can be widely used in reclaiming fields from the sea, deep water is enclosed and cultivated epeirogenetic, submerged structure excavation of foundation pit cofferdam, marine man-made island, river training works etc.Economic benefit and obvious social benefit have good popularization and application prospect.
The chemical fibre woven cloth of indication of the present invention is preferably the woven cloth of polypropylene material.This material has water permeability and certain tension, tearing toughness preferably, and antiseep and corrosion resistant performance satisfy the requirement of confferdam and dyke-dam construction.The specification of cloth bag can be made according to the needs of confferdam and dyke-dam design, and the length of large-scale cloth bag can reach 100 meters, and width can reach 40 meters.Used earth material is generally selected sandy soil for use, can light loam be the earth material that charges also.Its requirement is after earth material enters in the cloth bag, the soil body can be under the deadweight effect discharging consolidation rapidly.Building a dam in the sand pocket cofferdam that charges mud with the chemical fibre cloth bag, changes the traditional method of attacking and occupying construction into flat stifled upwards construction, takes to spread out completely to reserve to close to disturb mouth, improves the job practices of dam body in same level.
Claims (5)
1, a kind of job practices of confferdam and dyke-dam, it is characterized in that with chemical fibre woven cloth and earth material be material, earlier the chemical fibre woven cloth is sewn into the cloth bag of dredging tube inlet, cloth bag is laid the location after, charge in cloth bag by a bag gradation and to be full of earth material in the mud cloth bag and to be consolidated into the sand pocket confferdam and dyke-dam.
2, method according to claim 1, it is characterized in that said with cloth bag laying location, be successively to lay the location cloth bag, in bag, charge mud by the bag gradation, treat down one deck cloth bag be full of earth material fixed after, repave the last layer cloth bag and in bag, charge mud, successively increase, the multilayer bond becomes confferdam and dyke-dam.
3, method according to claim 1 and 2 when it is characterized in that said location cloth bag is meant for subaqueous construction, is provided with fixedly cloth bag of a bar in confferdam and dyke-dam footing sideline in advance.
