Description
Technical field
The invention belongs to technical field of civil engineering; Relate to the construction of ground foundation engineering and surrounding enviroment protection; Especially relating to steel sheet pile and go along with sb. to guard him the control construction of engineering and environmental hazard, specifically, is a kind of device and application process thereof that can suppress the foundation soil disturbance when pulling out steel sheet pile.
Background technology
The bracing of foundation pit body of underground engineering construction is to bear the soil pressure that pit earthwork excavation produced and the interim barricade of water pressure.The kind of bracing of foundation pit body is a lot, mainly contains steel sheet pile, reinforced concrete sheet pile, cement mixing method, cast-in-place concrete pile and diaphragm wall etc.Base pit engineering design consideration varying environment condition and construction characteristic are selected various envelope structures for use.In recent years, cement mixing method, cast-in-place concrete pile and diaphragm wall are as " disposable " structure of bracing of foundation pit, although its construction costs is higher, owing to engineering safety better is widely used.But the steel sheet pile space enclosing structure that ancient, traditional on the contrary repeated multiple times is used then more and more " is treated coldly " more and more marginalisation.
Steel sheet pile has longer developing history as foundation pit enclosure structure, once is the extensive use of various countries institute, and in China, the application of various large-scale " channel-section steels ", " Larsen " formula steel sheet pile (its section structure is shown in accompanying drawing 1) is also more common.The steel sheet pile fender body has a series of advantage, cheaper, reusable, pollution-free like space enclosing structure dependable performance, cost, as not have other cement class fender bodies requirement in the length of time, and it is convenient to construct.Yet, when pulling out, can cause steel sheet pile the disturbance of ground, and to the influence of surrounding enviroment, be its deadly defect, therefore influenced its application and development.
When steel sheet pile is pulled out to the disturbance of ground; Mainly be since steel sheet pile in the soil body in the uphill process; Taken a part of soil body of steel sheet pile " intraperitoneal " (in steel sheet pile) out of, the soil body that soil body viscosity is taken out of more greatly is many more, thereby in foundation soil, forms certain gap; Near it then displacement thereupon, sedimentation of the soil body plugs the gap with this.Wriggling, displacement, sedimentation that this foundation soil body is inner then can influence near underground utilities, building, produce displacement, sedimentation, make harm such as underground utilities damage, building sedimentation, inclination.
How to overcome steel sheet pile and pull out ground disturbance that is caused and the surrounding environment safety problem of bringing thus, let the steel sheet pile construction advantage manifest more, walk out the predicament of application, development, become important topic anxious to be solved in the ground foundation engineering construction.

The technology principle that the present invention relates to is following:
After the soil body in the steel sheet pile 6 is replaced as yellow ground; Owing to almost do not have cementation between yellow ground S and the steel sheet pile 6; Can not move, can not occur that the soil body is taken out of and in ground, produce the situation in space, make foundation soil keep stablizing motionless with the effect of increasing of steel sheet pile 6.
After steel sheet pile 6 was extracted from foundation soil, after its original occupied " space " was vacated, yellow ground is " cover " promptly, had prevented that " space " produces, and also just can not cause the change of soil body position.
In brief, after the soil bodys in the steel sheet pile 6 were replaced as yellow ground, because the characteristic of yellow ground S, it can not brought out by steel sheet pile 6, can also timely and effectively adds among the space that is occurred, and foundation soil also just can not be by disturbance.
The soil body is implemented by the job practices of yellow ground S displacement in two steps in the steel sheet pile 6:
At first, adopt jetting to wash the soil body in the steel sheet pile 6 open, form the hole of the about 300mm of diameter towards rifle 4 inject high pressure water.Hole is because the water pressure and the native arching action soil body are metastable.
And then in second step, in hole, insert yellow ground S exactly, displacement has also just been accomplished.
The soil body of being replaced is discharged in steel sheet pile 6 along with constantly washing away of water under high pressure naturally.
The special-purpose jetting that the present invention relates to is following towards the structure design feature of rifle 4:
In order effectively the soil bodys in the steel sheet pile 6 to be washed open, control punching hole diameter well, guarantee that the soil bodys in the steel sheet pile 6 can in time and obtain replacing up hill and dale, the present invention has designed special-purpose jetting towards rifle 4.
As shown in Figure 2, jetting is that a jetting is towards rifle head 43 towards the end of gun barrel 42; Jetting comprises towards rifle head 43 and is positioned at least two pair reamings of jetting on towards the conial tube of gun barrel 42 lower ends 432 and the jetting that is welded on next-door neighbour's conial tube 432 tops towards gun barrel 42 outer walls with steel floor 431.
Its radial symmetric of tube wall upper edge, upper end of conial tube 432 is provided with at least two couples of downward-sloping jetting hole 432a; The bottom of conial tube 432 is provided with at least one vertical jetting hole 432b between two parties; Jetting is connected with two pairs of reamings that radially are symmetrically distributed with steel floor 431 on the outer wall of gun barrel 42 near conial tube 432.
Jetting is a U type bend pipe 41 towards the top of rifle 4, can make jetting towards gun barrel 42 and high-pressure hose 3 rounding ofves and be connected to the port of export of high-pressure hydraulic pump 2, and it can reduce head loss preferably.
Jetting is distributed with 5 jetting holes and two pairs on the rifle head 43 along its external diameter>=Ф 50mm, " guarantor aperture " steel floor 431 that the jetting of≤100mm is uniformly distributed with towards the outer wall radial symmetric of gun barrel 42.
Embodiment 1
As shown in Figure 3, the jetting hole is pressed 1+4 and is distributed, and wherein 1 aperture jetting hole 432b that is Ф 8mm is arranged on the bottom dead center position of conial tube 432, and water under high pressure sprays vertically downward; The jetting hole 432a that other 4 apertures are Ф 6mm is arranged on the upper end tube wall of conial tube 432, and its jetting direction and horizon or jetting are 45 ° angle between the axis of gun barrel 42 and conial tube 432, and water under high pressure is to tilting to spray all round.
Jetting is welded with two pairs like Fig. 2 or " guarantor aperture " steel floor 431 shown in Figure 3 on rifle head 43; Its specification is: 5mm * 112.5mm * 150mm; Steel floor 431 is welded on its external diameter>=50mm at the sustained height radial equipartition, and the jetting of≤100mm is on the outer wall of gun barrel 42.The clear distance H in the two steel floor that is oppositely arranged 431 its Outside Dimensions≤steel sheet pile abdominal cavities is about 300mm (this size can be carried out the matching adjustment according to the specification of different steel sheet piles), guarantees that promptly institute's punching hole dia is equivalent to the Intraabdominal clear distance H of steel sheet pile.
The present invention relates to pull out steel sheet pile the time can suppress the application process of the device of foundation soil disturbance, its constructing operation flow process is referring to Fig. 6.
