Description
Technical field
The utility model relates to sealing material, and particularly a kind of Larssen steel-board magnetic stopping strip when the Larsen steel sheet-pile cofferdam draws water operation, utilizes this sealing rod to play sealing function, reduces outside water and infiltrates in the cofferdam.
Background technology
Steel sheet pile began in Europe to produce from 20 beginnings of the century, and steel sheet pile has the light-duty and hot rolling type of cold bending thin wall, because the former has bigger processing, use limitation, thereby the hot-rolled steel sheet pile becomes the main flow of steel sheet pile production development.Because it is be subjected to the influence of cheap land resources and manpower, domestic production is in space state substantially in addition,, very slow with development in the application of China as the steel sheet pile of metal building material.Along with China's rapid economy development, all kinds of building worker's methods quick, efficient, environmental protection are approved and are developed that in 20 end of the centurys, the steel sheet pile application project of China has certain development.Undoubtedly, 21 century the first half, the extensive use of steel sheet pile will be started new era of Chinese water conservancy project and foundation construction building field, the new revolution of achievement Chinese architecture worker method.
The basic structure of Larsen steel sheet pile is as shown in Figure 1: steel pile 4, both sides are snap closes 41, and each steel sheet pile 4 fastens mutually by snap close 41 and connects into wall construction, and a plurality of Larsen steel sheet piles in the ground or constitute wall in the water are realized the cofferdam operation.In the middle of the cofferdam construction process, the Larsen steel sheet pile utilizes the mutual padlock of the joint design on both sides, surrounds wall construction in water, then the water in the cofferdam is extracted out, conveniently carries out other constructing operation.
In the prior art, general way is with fillers such as cotton-wool and butter filling seam in Larsen steel sheet pile construction process in the cofferdam construction in Larsen steel sheet pile water; Perhaps all insert that beating finishing and begin to draw water installation when enclosing purlin at the Larsen steel sheet pile, adopting draws water on one side slips the carefully method of things such as more dried fine sand, thin cinder, wood chip, cavings under the seam of Larsen steel sheet pile, by in the fore shaft of water pressure suction Larsen steel sheet pile and reach the leak stopping purpose.For the big seam of some distortion, after enclosing the purlin installation,, reach the purpose of sealing again with cotton-wool filling or timber wedge wedging.
There is following defective in prior art:
1. stagnant water effect is undesirable.The Larsen steel sheet pile can occur rocking, and also can occur the slit between the cofferdam in the process of deep water cofferdam because the stormy waves in the water is big, cotton-wool, and fillers such as butter filling seam causes easily and comes off, and more can not have the effect of sealing because deep-water pressure is excessive.
2. can not use complicated operation repeatedly.No matter be that fillers such as cotton-wool and butter are clogged seam in advance, still while the thin things such as the more dried fine sand of slide, thin cinder, wood chip, cavings under the seam of Larsen steel sheet pile that draw water, the capital influences the progress of engineering, and often beginning can sealing, just can leak again again in very short time, cause very big influence to construction.
3. capacity of anti-storm is poor.As everyone knows, have stormy waves in the subaqueous work process cofferdam is impacted, this situation at deepwater work is especially obvious, and the external impact that the morning and evening tides of Jiang Haizhong, typhoon cause does a lot of damage for existing temporary transient filler, often breaks away from soon and leaks.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and Larssen steel-board magnetic stopping strip is provided, in order to solve the unfavorable problem of stagnant water effect that exists in the prior art.The utility model Larssen steel-board magnetic stopping strip is used in the middle of the Larsen steel sheet pile cofferdam construction, improve the effect of sealing, reduce the pump-out of water pump, energy conservation, accelerate the progress of construction, the purpose of this utility model also is the sealing rod repeated use, keeps the neat and tidy of cushion cap work plane, improves constructor's working environment.
The technical solution of the utility model:
Larssen steel-board magnetic stopping strip is characterized in that the strip shape body of described sealing rod for making with flexible material, is embedded with magnetic in this strip shape body along its length.
The boss in the middle of described strip shape body comprises and the flap of both sides, the one side of this strip shape body is recessed cambered surface, the centre of another side is a boss.
The outside of described boss cross section is circular arc or the drift angle shape with angle or square.
Described magnetic is continuous strip or magnetic aggregation.
Strip, bulk or the magnetic aggregation of described magnetic for being interrupted.
Described magnetic is continuous strip or magnetic aggregation, and magnetic is row, be embedded in the described boss, or magnetic is two row, is embedded at respectively in described two side flaps.
Strip or the magnetic aggregation of described magnetic for being interrupted, magnetic is row, be embedded in the described boss, or magnetic is two row, is embedded at respectively in described two side flaps.
Described magnetic is two row, and this two row magnetic is embedded at respectively in described two side flaps, also is provided with along the bar hole of sealing rod direction in the described boss.
Described flexible material is rubber or is organic polymer.
Technique effect of the present utility model:
1. stagnant water effect ideal.Larssen steel-board magnetic stopping strip of the present utility model utilizes magnet to be adsorbed in the place, snap close slit of Larsen steel sheet pile earlier, after in the cofferdam, drawing water, utilize inside and outside pressure differential, make sealing rod be adsorbed in firmly between the Larsen steel sheet pile, utilize the sealing of the flap realization of boss and its both sides to the snap close slit, and because be made with flexible material, the Larsen steel sheet pile that can not cause along with the influence of extraneous factors such as stormy waves is out of shape and leaks.
2. anti-external environment ability is strong.In the cofferdam construction process of sea, river, can run into various bad weathers, although the Larsen steel sheet pile that the cofferdam is used has snap close each other, but distortion still can occur and strengthen the slit and leak, sealing rod of the present utility model has reduced the possibility that the slit occurs and leak because of the flap of both sides, has strengthened the ability of resisting extraneous adverse circumstances greatly.
3. can use convenient construction repeatedly.The utility model Larssen steel-board magnetic stopping strip is after the Larsen steel sheet pile is all squeezed in the water, from bottom to top be installed to the place, slit of Larsen steel sheet pile by the diver, rectangular shape can place gap position easily, conveniently takes off again after construction is finished, and uses so that continue next time.
