Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
In addition, term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance
Or implicitly indicate the quantity of indicated technical characteristic.Define " first " as a result, the feature of " second " can be expressed or
Implicitly include one or more of the features.In the description of the present invention, the meaning of " plurality " is two or more,
Unless otherwise specifically defined.
Referring to FIG. 1, Fig. 1 is the fast pore-creating technique provided in an embodiment of the present invention used for Soft Soil Layer anti-float anchor rod
The flow chart of method, the fast pore-creating process include the following steps:
S100, by casing in hollow structure along perpendicular to being inserted in Soft Soil Layer on the direction of weak soil layer surface；
Due to the characteristic that Soft Soil Layer natural moisture content is big, compressibility is high, low bearing capacity and shearing strength are low etc., in Soft Soil Layer
Easily there is the problem of hole wall collapse, difficult forming in direct pore-forming.Therefore, the tube wall of the casing of hollow structure is directlyed adopt as anchor
The molding hole wall of bar.
S200 forms negative pressure in casing to reduce the air pressure pressure of casing front end.
Since casing is during pre-buried, front end is contacted with Soft Soil Layer easily forms air cavity, and air cavity can hinder sleeve pipe pre-embedding
Process.Therefore, negative pressure is formed in casing, the air pressure pressure of air cavity is discharged by casing to outside, in this way, it is pre- to reduce casing
Resistance during burying improves construction efficiency.
The fast pore-creating process provided in an embodiment of the present invention used for Soft Soil Layer anti-float anchor rod, utilizes casing
Hole wall of the tube wall as forming anchor pole, when so as to avoid Soft Soil Layer, anchor pole is set the problem of occurred hole wall collapse, meanwhile,
Negative pressure is formed in casing with reduce casing front end it is pre-buried when resistance, improve construction efficiency.
Embodiment one
In the present embodiment, S100, by casing in hollow structure along perpendicular to being inserted on the direction of weak soil layer surface

Another flow chart of method further includes following steps, concrete cushion is arranged on Soft Soil Layer in the step s 100, passes through vibration
The front end of casing is successively vertically worn concrete cushion and Soft Soil Layer by dynamic hang down, also, is embedded in Soft Soil Layer in advance.
Due to the above-mentioned characteristic of Soft Soil Layer, directly carry out deforming at the pre-buried aperture for easily leading to Soft Soil Layer of casing,
It causes the gap between the rear end of casing and Soft Soil Layer to become larger, and then leads to the pre-buried position run-off the straight of casing, be unfavorable for
Subsequent anchor bolt construction.Therefore, a layer concrete bed course is added, on Soft Soil Layer to guarantee that casing is vertically embedded in Soft Soil Layer in advance
In.
