Technical Field
[0001] The utility model relates to the technical field of foundation pit row pile support piles, in particular to a foundation pit row pile support pile reinforcement device. Background Art
[0002] Piles in rows for foundation pit support are a common support form consisting of support piles, supports or anchors, and anti-seepage curtains. It can be divided into cantilever support structure, anchor support structure, internal support structure, and anchor support structure according to the construction situation, and can also be divided into steel pipe piles, precast concrete piles, bored piles, and cast-in-place piles according to the pile type. The advantages of pile row support include convenient construction, good safety, and low cost. Since this support form generally has no supporting structure in the foundation pit, it is convenient for on-site earthwork excavation operations. At the same time, this support form has the dual functions of retaining soil and stopping water, so it is also more economical; there is no vibration and noise during the construction process, there is relatively little pollution, and the soil squeezing effect is small.
[0003] During the use of foundation pit piles, additional supporting piles are usually required to increase the structural strength of the piles. However, the existing supporting piles are relatively simple in structure when in use, and only form a physical support barrier inside the piles. They cannot form a complete force inside the piles during pouring, and their firmness and tensile strength are insufficient. They cannot reinforce the piles, supporting piles and foundation pits, which causes certain inconveniences. Based on this, we propose a foundation pit pile supporting pile reinforcement device.
