Later drainage device for foundation pile and installation method
A later drainage device for a foundation pile and an installation method aim at solving the technical problems that a foundation pile in the prior art is not provided with a corresponding later drainage device, steel parts in the foundation pile are prone to rusting corrosion, and consequently the long-term service life of the foundation pile is influenced, or, when the water permeability of a soil layer where the foundation pile is located is high, a large amount of moisture deposits in the soil layer in contact with the lower end face of the foundation pile, the soil layer generates too large deformation after being disturbed, and consequently the stability of the foundation pile is influenced. The later drainage device comprises a water collecting layer with the water content being always lower than that of the soil layer near the foundation pile, the water collecting layer is arranged in a water collecting cavity, an installation chamber is arranged below the water collecting layer, squeezing components driving the water collecting layer to move close to the top wall of the water collecting cavity are installed in the installation chamber, liquid in the water collecting layer can flow into a water collecting well on the bottom face of the installation chamber through drainage holes in the squeezing components, liquid in the water collecting well is driven through a drainagecomponent to flow into a liquid storage box on the ground surface, and the water collecting layer and the soil layer outside the water collecting cavity can carry out liquid exchange through liquid exchange holes in the wall of the water collecting cavity.
一种基桩的后排水装置及安装方法，旨在解决现有技术中基桩没有相应的后排水装置，基桩中的钢制件容易产生锈蚀，进而影响基桩的长期使用寿命，或者，当基桩所在土层透水性较高时，大量水分沉积在与基桩下端面接触的土层中，该土层受扰动后产生过大变形，进而影响基桩的稳定性的技术问题。本发明包括含水量始终低于基桩附近土层的含水量的集水层，集水层设置在集水腔中，集水层下方设有安装室，安装室中装有驱动集水层贴近集水腔的顶壁运动的挤压构件，集水层中的液体可经挤压构件上的排水孔流入安装室底面上的集水井中，集水井中的液体经排水构件驱动流入地表上方的储液箱中，集水层与集水腔外的土层可通过集水腔腔壁上的换液孔进行液体交换。
