Problems solved by technology

To sum up, it is easy to cause different degrees of hole-forming deviation in the upper soil part of the artificially excavated anti-slide pile; The repair method takes a long time, and as time goes on, it may also cause the risk of secondary inclination of the pile hole and cause damage; affected by the tight construction schedule and bad weather, how to find a fast and cost-effective anti-slide pile The construction method of repairing damaged holes is particularly important

Embodiment 1

[0027] Embodiment 1: in step (1), as figure 2 As shown, before stripping the retaining wall 3 within the deformation depth range of the pile hole 5, first judge the vertical deformation offset of the pile hole 5, when the vertical deformation offset of the anti-sliding pile pile hole 5 is less than the When the thickness is high, the lock 6 at the top of the pile hole 5 is reserved, and the part of the retaining wall 3 within the range of the inclined deformation depth close to the slip layer 2 is grooved and repaired; Directly adopt the formwork 4 set on the retaining wall 3 to close the mold and keep the original retaining wall 3, so that the verticality of the corrected pile hole 5 is within the vertical deviation range specified by the design, so as to form the corrected pile hole 5; The shifting layer 2 refers to the side of the protective wall 3 directly impacted by the sliding layer 2 , and the distance away from the sliding layer 2 refers to the side of the protective...

Embodiment 2

[0033] Embodiment 2: in step (1), as image 3 As shown, before stripping the retaining wall 3 within the deformation depth range of the pile hole 5, the vertical deformation offset of the pile hole 5 is first judged. At the same time, first remove the deformed locking opening 6, and then excavate the slip layer near the anti-slide pile hole 5 according to the deformation depth of the anti-slide pile hole 5, and the excavation depth corresponds to the deformation depth of the retaining wall 3 to form On the working face, dismantle the retaining wall section of the deformation depth, and then build a lock 7 at the upper end of the retaining wall 3 left after the removal, and the part from the newly built lock 7 to the design top elevation constitutes the empty section 8; The formwork 4 matching the aperture of the hole 5 is used for support, and the lower part of the formwork 4 is fixed on the upper surface of the new lock 7. The top elevation of the formwork 4 is equal to the d...

Abstract

The invention discloses a construction method of emergency rescue engineering after damage of a pile hole of an anti-slide pile. The upper part of the pile hole of the anti-slide pile inclines to a certain direction when the hole is formed already or can be formed soon, and the hole is damaged, a locking opening is formed in the top of the pile hole, a concrete protection wall is paved on the inner wall of the pile hole, and the method comprises the following steps that the protection wall in the deformation depth range is correspondingly stripped according to the different deformation situation and is supported by being combined with a template to form a corrected pile hole; the perpendicularity of the corrected pile hole is measured by adopting perpendicularity measuring equipment, and thus the perpendicularity of the corrected pile hole is in the deviation range of design regulation; and pile body rebar cage binding is conducted on the pile hole in the deviation range of design regulation, and finally pile core concrete casting is conducted. According to the construction method of the emergency rescue engineering after damage of the pile hole of the anti-slide pile, under the situation that safe and civilized construction is guaranteed, and the work period of repairing the inclined pile hole can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of inclination treatment of building anti-sliding piles, in particular to a construction method of an anti-sliding pile in an emergency rescue project after the hole is damaged. Background technique [0002] Emergency rescue and geological disaster projects are often located in unstable areas or on slopes, where the geological conditions are harsh, and they are prone to geological slippage or deformation due to the influence of rainwater. During the implementation of anti-slide piles, affected by the site, manual excavation piles are generally used. . After the manual hole-digging piles have completed the work of locking and retaining walls, it is necessary to carry out manual hole cleaning construction and steel bar binding and other processes, and finally complete the pouring of concrete. Before concrete pouring, in case of heavy rain or other factors, the overall slope in the area is in an unfavorable st...
