Description

TECHNICAL FIELD

[0001] The utility model relates to an anti -slip pile technical field, concretely relates to a double -row anti -slip pile retaining structure. BACKGROUND

[0002] At present, in landslide treatment engineering, anti -slip pile is widely used in landslide treatment engineering and high and steep slope support engineering because of its small masonry work quantity, flexible pile position arrangement, strong adaptability and the like. The anti -slip pile is the pile column that is inserted into landslide and is deep into stable stratum, and the anchoring effect of stable stratum is utilized to resist the thrust of landslide, and the effect of maintaining landslide stability is maintained. In the prior art, simple single row or double row anti -slip pile arrangement is mostly adopted to realize landslide treatment, and for the treatment engineering of large -scale landslide, due to the limitation of pile spacing and landslide width, only setting single row anti -slip pile and double row anti -slip pile cannot meet the requirement of anti -slip force, and other measures need to be increased on the basis of anti -slip pile to improve the anti -slip capacity of the whole structure.

[0003] The patent file with the publication number CN215211096U discloses a combined double-row anti-sliding pile retaining structure, and the construction process of the retaining structure includes the following steps:

[0004] Step one: according to the geological conditions and surrounding environmental conditions of landslide or slope, select the appropriate position, adopt mechanical rotary digging hole, lower the steel reinforcement cage with sleeve pipe, and pour concrete.

[0005] Step two: after the strength of the pile body of the front row of anti-sliding piles reaches 80% of the design strength of the concrete for 28 days, the construction of the rear row of anti-sliding piles is started, the drilling position of the rear row of anti-sliding piles forms a plum blossom shape with the front row of anti-sliding piles, and the construction steps are the same as step one.

[0006] Step three: after step two is completed, the main reinforcement of the connecting beam is bound with the main reinforcement of the anti-sliding pile, and overall pouring is carried out.

[0007] Step four: open the pre-buried sleeve pipe at the upper part of the concrete pile, and remove the internal clay.

[0008] Step five: pass the pre-stressed anchor cable through the sleeve pipe, fix the anchor head on the side opposite to the slide bed of the anti-sliding pile, along the inclined direction of the sleeve pipe, and drive the pre-stressed anchor cable into the slide bed, and grouting is carried out at the anchor segment of the anchor cable for fixation, after the strength of the grouting body reaches the design strength, the pre-stressed anchor cable is appropriately tensioned according to the design pre-stress requirement.

[0009] In the construction process of the retaining structure, the two rows of anti-sliding piles need to be constructed with a long time interval, and after pouring, the concrete needs to be solidified to the design strength, so the construction time is long. When installing the anchor cable, the pre-buried sleeve pipe at the upper part of the concrete pile needs to be opened first, the internal clay is removed, and then the installation of the anchor cable is carried out, which is troublesome and low in efficiency.
