Abstract
The invention discloses a kind of methods handling anchor cable using churning driven, include the following steps：A, during subway shield tunnel construction, when encountering existing anchor cable (2), the anchor cable (2) is cut off with churning driven (1), discharges the tension stress of the anchor cable (2)；Part in the anchor cable (2) is taken out of by churning driven (1), and other two sections of anchor cables after cutting off form free end and remain in the earth formation；B, after churning driven (1) construction, rock stratum (3) is backfilled using C20 concrete, soil layer (4) is backfilled using M5 cement mortar；C, carry out shield-tunneling construction again, shield driving by when, select suitable boring parameter, will be squeezed to the soil at both sides of shield as the anchor cable of free end, realize tunneling construction of the shield by anchor cable section.The method for handling anchor cable using churning driven of the present invention, will not have an impact surrounding building, and the duration is shorter, engineering cost is relatively low.
Description
Technical field
The present invention relates to technical field of tunnel construction, and in particular to a method of anchor cable is handled using churning driven.
Background technology
With the rapid development of cities in China rail traffic, in urban rail transit shield work progress often
Encounter various underground obstacles.Currently, most cities skyscraper is equipped with basement, urban construction basement encloses
Protection structure largely uses the form of cable bolting, this constructs to urban rail transit shield and generates large effect.
And for underground anchor rope processing it is current domestic occur similar in the case of be also it is more, processing method difference it is larger but
Substantially be to clear up in advance anchor cable, take method it is common there is pipe-following drilling set to follow the example of, artificial digging pile segmentation pull out
Method, chute forming machine crawl method, full-sleeve slewing drilling machine patterning method etc., and the interaction between shield driving and anchor cable is ground
Study carefully less；The good and bad index of evaluation anchor cable processing construction is construction period, the influence to surrounding enviroment and engineering cost；It is common
Pipe-following drilling set follow the example of the basement side wall that need to abolish existing building, be affected to existing building；Artificial digging pile point
Method that section is pulled out, chute forming machine crawl method, full-sleeve slewing drilling machine patterning method construction area area are big and long in time limit, engineering cost
It is high.
Since churning driven is directly constructed in subway shield tunnel construction range, and rotary drilling rig footprint is smaller, uses
Churning driven processing anchor cable will not have an impact surrounding building, and the duration is shorter, and engineering cost is relatively low, and applicability is wide, because
This, there is an urgent need for designing a kind of completely new processing scheme coordinated using churning driven and shield machine, to handle anchor cable.
Invention content
The object of the present invention is to provide a kind of methods handling anchor cable using churning driven, will not be generated to surrounding building
It influences, and the duration is shorter, engineering cost is relatively low.
To achieve the above object, a kind of method that anchor cable is handled using churning driven provided by the present invention, including walk as follows
Suddenly：
A, during subway shield tunnel construction, when encountering existing anchor cable (2), the anchor cable is cut off with churning driven (1)
(2), the tension stress of the anchor cable (2) is discharged；Part in the anchor cable (2) is taken out of by churning driven (1), and after cutting off other two
Section anchor cable forms free end and remains in the earth formation；
B, after churning driven (1) construction, rock stratum (3) are backfilled using C20 concrete, M5 is used to soil layer (4)
Cement mortar is backfilled；
C, carry out shield-tunneling construction again, shield driving by when, select suitable boring parameter, will be as the anchor of free end
Rope is squeezed to the soil at both sides of shield, realizes tunneling construction of the shield by anchor cable section.
In the above-mentioned method for handling anchor cable using churning driven, in the step (a), churning driven (1) is in ground construction.
The present invention has the advantages that compared with prior art：
Since churning driven is directly constructed in subway shield tunnel construction range, and rotary drilling rig footprint is smaller, uses
Churning driven processing anchor cable will not have an impact surrounding building, and the duration is shorter, and engineering cost is relatively low, and applicability is wide；This
Although part construction risk, by whole anchor cables in range, is transferred to shield machine pick by inventive method without fully erased shield
Into in the process, but it is flexible with rotary digging pile layout, and quantities is few, and cost is controllable, rotary drilling rig machine source is sufficient, speed of application
Soon, stake position positioning accuracy is high, anchor cable cut off situation it is controllable, using mud off, the advantages that construction safety risk is controllable, be suitble to anchor
The processing of rope is constructed.
Description of the drawings
Fig. 1 is a kind of construction schematic diagram of method handling anchor cable using churning driven of the embodiment of the present invention.
Wherein, 1, churning driven；2, anchor cable；3, rock stratum；4, soil layer.
Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
As shown in Figure 1, a kind of method handling anchor cable using churning driven provided by the present invention, includes the following steps：
A, during subway shield tunnel construction, when encountering existing anchor cable 2, the anchor cable 2 is cut off with churning driven 1, is discharged
The tension stress of the anchor cable 2；Part in the anchor cable 2 is taken out of by churning driven 1, and other two sections of anchor cables after cutting off form freedom
It holds and remains in the earth formation；
B, after churning driven 1 is constructed, rock stratum 3 is backfilled using C20 concrete, M5 cement bonded sands are used to soil layer 4
Slurry is backfilled；
C, carry out shield-tunneling construction again, shield driving by when, select suitable boring parameter, will be as the anchor of free end
Rope is squeezed to the soil at both sides of shield, realizes tunneling construction of the shield by anchor cable section.
Preferably, in the step (a), churning driven 1 is in ground construction.
To sum up, the present invention has the advantages that compared with prior art：
Since churning driven is directly constructed in subway shield tunnel construction range, and rotary drilling rig footprint is smaller, uses
Churning driven processing anchor cable will not have an impact surrounding building, and the duration is shorter, and engineering cost is relatively low, and applicability is wide；This
Although part construction risk, by whole anchor cables in range, is transferred to shield machine pick by inventive method without fully erased shield
Into in the process, but it is flexible with rotary digging pile layout, and quantities is few, and cost is controllable, rotary drilling rig machine source is sufficient, speed of application
Soon, stake position positioning accuracy is high, anchor cable cut off situation it is controllable, using mud off, the advantages that construction safety risk is controllable, be suitble to anchor
The processing of rope is constructed.
It the above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, without departing from the technical principles of the invention, several improvement and replacement can also be made, these improve and replace and also answer
It is considered as protection scope of the present invention.
