Description

Improved watertight continuous foundation piles

The present invention relates to a foundation pile waterproof structure, in particular to an improved watertight continuous foundation pile.

The fully casing type excavation concrete foundation pile is a type of field-cast concrete foundation, referred to as the all-casing pile (All-casing Pile). It mainly uses steel casing to protect the pile hole wall, and uses a pipe shaker to twist and press the steel casing into the soil. In the layer, use a drill bit or a hanging grab bucket to excavate the earth and rock in the pipe, press in the casing and excavate the earth and rock alternately until the designed depth is reached, then hoist the steel cage, remove the sediment at the bottom of the pile, and pour concrete in the water with a special dense pipe , as the height of the concrete increases, the casing is removed at the same time to complete the construction of the foundation pile.

Based on the above, in the current full casing construction, due to the limitation of pile diameter, the distance between two piles during continuous construction is often prone to water seepage. Since water seepage will affect the strength of the overall structure, the water stop problem between foundation piles is now a problem. Waterproofing is an important issue that needs to be improved. Currently, there are still no proper, simple and effective waterproofing measures. In view of this, the inventor worked hard and devoted himself to research, and finally completed the improved watertight continuous foundation pile invented in this case to overcome the shortcomings of the conventional technology.

In view of the above, the main purpose of the present invention is to provide an improved watertight continuous foundation pile, which can effectively stop water between the foundation piles and prevent the weakening of the structural strength.

Another object of the present invention is to provide an improved watertight continuous foundation pile that can be applied to existing construction operations and does not require additional pile joint water-stopping construction, thereby improving the construction quality of foundation piles and having the advantage of saving construction costs. effect.

In order to achieve the above purpose, the present invention is an improved watertight continuous foundation pile, which includes a casing part and a water stop part. The casing part is a hollow cylindrical casing that can be sleeved on the steel foundation pile installed under the ground. Outside; the water-stop part is arranged inside the casing part. The water-stop part is a pair of structures, symmetrical to the longitudinal axis passing through the center of the casing part. The water-stop part further includes a steel curved plate and a water-stop belt. The steel curved part The panel is in the shape of an arc plate and is concave toward the center of the casing part; the water stop is made of waterproof material and is attached to the inside of the steel curved panel near the center of the casing part. The casing part and the water stop are shown in a top view The cross-section is slightly U-shaped; after grouting, the casing part is removed from the outside of the steel pile. The water-stop part is retained and attached to the outer wall of the steel pile. The water-stop part blocks water from penetrating into the steel bar. The outer wall of the foundation pile is waterproof; the left and right sides of the reinforced foundation pile have a left male unit full casing excavation pile and a right male unit full casing excavation pile, a left male unit full casing excavation pile and a right male unit full casing excavation pile. A left male unit full casing casing part and a right male unit full casing casing part can be respectively set outside the pipe excavation pile, and the left male unit full casing casing part and the right male unit full casing casing part can respectively have The water stop part, in other words, the present invention can be extended to the left and right into a plurality of casing parts as required.

In summary, the improved watertight continuous foundation piles of the present invention can be directly installed in existing construction operations, are highly flexible, and do not require additional pile joint water-stopping construction, which can save costs and improve economic benefits; and are waterproof It has good properties and will not weaken the overall structure.

Various embodiments are proposed for detailed description below with reference to the drawings. However, the embodiments are only used as examples and do not limit the scope of the present invention.

Figure 1 is a schematic diagram of the unit of the present invention. Figure 2 is a schematic top view of the unit of the present invention. Please refer to Figures 1 and 2 at the same time. As shown in the figures, the present invention is an improved watertight continuous foundation pile 1, including a casing part 10 And the water stop part 20, the casing part 10 is a hollow cylindrical casing, and the casing part 10 can be sleeved on the outside of the reinforced foundation pile installed under the ground. The casing part 10 can be, for example: a steel full casing ( steel all-casing), but is not limited to this; the water stop part 20 is arranged inside the casing part 10. The water stop part 20 is a pair of structures, with the longitudinal axis passing through the center of the casing part 10 being left and right symmetrical. ; The waterstop part 20 further includes a steel curved plate 202 and a waterstop belt 204. The steel curved plate 202 is in the shape of an arc plate and is concave toward the center of the casing part 10. The steel curved plate 202 is in the shape of two symmetrical pieces. Structure; the waterstop 204 is made of waterproof material. The waterstop 204 is set and attached to the inside of the steel curved panel 202 near the center of the casing part 10. As shown in Figure 2, the casing part 10 and the waterstop 20 are viewed from above. Its cross-section is slightly U-shaped.
