Embodiment 1

[0030] see Figure 1 to Figure 2 As shown, the present invention provides a self-waterproof support pile, which includes a support pile body 1, and vertical waterproof belts 2 made of water-swellable rubber are respectively provided on opposite sides of the support pile body 1.

[0031] It should be noted that water-swellable rubber is also called water-swellable rubber, which belongs to the prior art. For example, the utility model patent with application number 201820972727.X discloses a double U-shaped water-swellable rubber waterstop, and application number The patent application for 201510403848.3 discloses a water-swellable rubber waterstop end sealing device. Water-absorbing swellable rubber is a new type of functional polymer material that can double stop water through elastic sealing and water-absorbing expansion. The high elasticity and good mechanical strength of rubber make the rubber expand several to hundreds of times after absorbing water, which can overcome the...

Embodiment 2

[0041] see image 3 As shown, the present invention provides a self-waterproof support system, the self-waterproof support system includes N self-waterproof support piles as described in the first embodiment above, and the N self-waterproof support piles are arranged in sequence One column, N is an integer greater than or equal to 2; if there is the i-1th self-waterproofing support pile, a vertical waterproof zone 2 of the i-th self-waterproofing support pile and the i-1th self-waterproofing support pile A vertical waterproof belt 2 is set adjacent to each other. If there is an i+1th self-waterproof support pile, another vertical waterproof belt 2 of the i-th self-waterproof support pile and the i+1th self-waterproof support pile A vertical waterproof belt 2 adjacent to each other, wherein, i is an integer selected from 1-N.

[0042] Since the above-mentioned self-waterproof support system is provided with the above-mentioned self-waterproof support pile, the above-mentioned ...

Abstract

The invention provides a self-waterproof support pile. The self-waterproof support pile comprises a support pile body, vertical waterproof belts with materials being water swelling rubber are correspondingly arranged on the opposite two sides of the support pile body. According to the self-waterproof support pile, the vertical waterproof belts with the materials being the water swelling rubber arecorrespondingly arranged on the opposite two sides of the support pile body, the vertical waterproof belts are attached to the support pile body, before construction, the vertical waterproof belts are in the contraction state, construction of adjacent support piles cannot be influenced, after construction is completed, water swelling is conducted on the vertical waterproof belts, and gaps are sealed to achieve the effect of sealing up. Therefore, according to the self-waterproof support pile, construction of the adjacent support piles cannot be influenced, gap sealing and the sealing up effect can also be achieved after support pile construction is completed, waterproof curtains can be saved, and the engineering cost is lowered to a certain extent. The invention further provides a self-waterproof support system containing the self-waterproof support pile.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a self-waterproof support pile and a self-waterproof support system comprising the self-waterproof support pile. Background technique [0002] Supporting piles refer to piles that mainly bear lateral thrust. They are generally used for foundation pit support, slope support, and landslide control. They bear horizontal soil pressure or landslide thrust. Tendons are also often used together with anchor rods (cables) (pile-anchor structures). [0003] Supporting piles are widely used in water conservancy projects, river improvement and deep foundation pit projects. The general method is to separately make a water-stop curtain forming a closed circle in addition to the supporting piles, which is not only costly, but also labor-intensive and time-consuming, and the construction environment is not good. If the bottom of the foundation pit is below the groundwater table and the pr...
