Description
Technical field:
The utility model relates to geotextiles laying apparatus under water, belongs to engineering machinery.
Background technology
Geotextiles can be isolated the material of different physical properties effectively, and two or more storerooms are not mixed mutually, keeps the overall structure and the function of material; With concentrated stress diffusion, transmission or decomposition, reduce uneven settlement of foundation effectively; Increase the tensile strength and the resistance ability of the soil body effectively, strengthen the anti-shearing destruction of ground, therefore, geotextiles is able to extensive use in the treatment of soft foundation engineering.In recent years, this technology was applied in the treatment of soft foundation under water.Profundal zone and even abysmal area geotextile laying can not adopt conventional artificial laying construction method, but want special-purpose ship construction, this just not only will solve the influence of deep-sea complex working condition to the safety work of construction hull, and will solve the influence of the complicated hydrologic condition of deep water to efficiency of construction and quality.
Will prevent not only that under water stormy waves is stable to hull, lay the adverse effect of precision, and will prevent the adverse effect of disorderly current to geotextiles, a series of adverse effects constitute sizable technical barrier.
Summary of the invention
In order to solve above-mentioned technical barrier, realize the smooth laying of geotextiles under water, the utility model purpose provides a kind of equipment of geotextile laying under water.
The utility model comprises buoyancy aid, navigation system, shift unit and laying mechanism.Adopt following technical scheme: four jiaos of buoyancy aid are provided with the location windlass, and the location windlass is controlled by coastal engineering ship's fix instrument; One side along buoyancy aid is provided with two cantilevers, and the pulley hoist cable on the cantilever connects the cylinder that volume is gone up geotextiles, and is controlled by hoist engine; The another side of buoyancy aid is provided with sandstone bag windrow cabin; The centre of buoyancy aid is provided with loop wheel machine and pulpit.
Described buoyancy aid is a working platform waterborne, require enough all equipment and personnel of carrying, have certain capacity of anti-storm, can ensure stable construction in the environment of the depth of water 2～20m, flow velocity 0～3m/s, tidal range≤9m, wind-force≤7 grade, wave≤2 grades, normal operation.Its design main points are: length of floating body is greater than the length of cylinder, and the length of cylinder is greater than the width of geotextiles.
Described location windlass is buoyancy aid location and mobile device, is made up of windlass, anchor hawser, anchor, cavil and electric control gear.
Described GPS positioning system using coastal engineering ship's fix instrument has 3 GPS receivers, industrial PC, two data radio stations and a cover working software.Positioning accuracy request≤20cm.
Described cantilever is the supporting mass that rises and falls of cylinder, the gross mass of the whole roller components of load-bearing.Cantilever is installed on an edge of buoyancy aid, and the cantilever lower end is fixed on the buoyancy aid, and the pulley hoist cable is equipped with in the upper end, in order to the lifting of index drum.The pulley hoist cable that cantilever links to each other connects is rolling up the cylinder of waiting to spread geotextiles, and is controlled by hoist engine.Hoist cable is the traction rigging of cylinder of rising and falling, owing to can produce big pulling force when laying, so hoist cable must have enough tensile strength and is not destroyed guaranteeing.
Cylinder places between two cantilevers, and two ends are connected by hoist cable.Cylinder is the critical piece of geotextiles when paving, and certain flexural strength, axiality requirement are arranged.Hoist cable is the traction rigging of cylinder of rising and falling.The length of cylinder is greater than the width of the geotextiles of once-paving.
Hoist engine is mainly the cylinder liter, puts device, and in order to regulate the degree of depth of cylinder, the undue mud that compresses is coated with face to prevent cylinder when laying, and makes the geotextiles cylinder difficult because of resistance rolls too greatly, causes geotextiles not open continuously.On the haulage gear of cylinder both sides, be provided with the hydraulic pressure self-locking device, prevent geotextiles, only when the laying ship moves, just understand release and rotate synchronously, make geotextile laying smooth-going and wrinkle resistant in the rotation of water movement bottom roll.
Described loop wheel machine is located at the middle part of buoyancy aid, and the radius of gyration of loop wheel machine is used to load and unload geotextiles and sandstone bag greater than half of buoyancy aid width.Pulpit is used for centralized Control loop wheel machine, hoist engine and windlass.
Characteristics of the present utility model are:
1. because the employing electric-controlled mechanical is finished the loading and unloading of lifting, displacement, laying and material goods, so mechanization and automaticity height.
2. owing to adopt the GPS navigation system, the precision height is laid in accurate positioning, and not wet dilation ebb, day and night and weather condition effect.Can all-weather construction, effective engineering time of every day can reach 24 hours.
3. owing to adopt cantilever, pulley to be connected cylinder with hoist cable and to be controlled by hoist engine.Geotextiles can be sunk to the bottom of rope capacity, solve the difficult problem that the deep water geotextiles can't be laid.
4. owing to adopt the design of buoyancy aid and four jiaos of location windlass of enough carryings, has higher wind and wave resistance stream ability, job stability.
