Embodiment Construction

[0045] Such as Figure 1 to Figure 5 As shown, the double-row pile structure with water-stop function of the present invention includes the concrete pouring pile 1 in the front row, the concrete crown beam 2, the steel pipe pile 3 in the back row, and the steel pipe pile between the concrete pouring pile 1 and the steel pipe pile 3. The water-stop curtain 4 and the concrete pouring pile 1 are connected through crown beams.

[0046] The opposite positions on the outer wall of the top of the steel pipe pile 3 are respectively provided with L-shaped connecting buckles 5 that cooperate with each other. Vertical connecting plate 51 and buckle plate 52, the plate surface of connecting plate 51 is arranged along the diameter direction of steel pipe pile 3, two connecting plates 51 connecting buckle plate 5 are located in the same plane; the inner surface of buckle plate 52 and The inner surface of the corresponding buckle plate 52 on the adjacent steel pipe pile 3 is attached to for...

Abstract

The invention relates to the technical field of double-row pile supporting, and discloses a double-row pile structure with a water stopping function and a construction method thereof. The double-row pile structure comprises front-row cast-in-place concrete piles, a concrete top beam, rear-row steel pipe piles and a waterproof curtain located between the cast-in-place concrete piles and the steel pipe piles. The cast-in-place concrete piles are connected through the top beam. The steel pipe piles are detachably connected through L-shaped connecting buckle plates, locking opening assemblies arearranged on the side walls of the cast-in-place concrete piles in the pile axial direction, and grouting pipes are arranged between the locking opening assemblies and the cast-in-place concrete piles.Connecting short plates are arranged between the cast-in-place concrete piles and the steel pipe piles which are opposite front and back. The steel pipe piles cooperate with the concrete piles, excellent water stopping performance is achieved, construction is easy, convenient and efficient, and part of the structure can be detached and recycled.

Description

technical field [0001] The invention relates to the technical field of double-row pile support, in particular to a double-row pile structure with water-stop function and a construction method thereof. Background technique [0002] In the construction of foundation pits in densely built urban areas, it is necessary to ensure the stability of the foundation pit itself and the safety of surrounding buildings. This requires the use of appropriate support schemes to monitor the horizontal displacement and settlement of the soil around the foundation pit. Restrict, meanwhile, set up water-stop curtains or precipitation wells to control groundwater. The double-row pile support structure has high rigidity and high strength, which can effectively ensure the safety of the foundation pit itself and surrounding buildings, and is widely used in deep foundation pit engineering. [0003] At present, the traditional support method of double-row piles is to arrange two rows of reinforced co...
