Description

Technical Field

[0001] The utility model belongs to the technical field of foundation engineering, and particularly relates to a slope retaining pile and a forming mould thereof. Background Art

[0002] Pile foundation is one of the oldest types of foundation. Piling is an important and indispensable part of all construction industries. The quality of piles determines whether the building is stable. The function of piles is to transfer the load of the upper building to the deep soil layer with strong bearing capacity, or to compact the weak soil layer to improve the bearing capacity and density of the foundation soil. The oldest piles are wooden piles made of wood. Wooden piles are inserted into the soil to support houses. With the development of the times, wooden piles are gradually replaced. A pile made of reinforced concrete is used on the construction site to determine the foundation. It is called pile foundation technology. It is the basic technology in the civil construction of construction projects. The application of this technology has greatly improved the stability of the building structure, brought into play the greatest functional benefits of the construction project, and made the construction project durable and earthquake-resistant. This type of pile is made directly on site, and before making it, it is first driven at a predetermined point. Next, dig a pit that is deep enough, build a steel frame, then surround the steel frame with wooden boards, and finally pour concrete. After a period of time, the wooden boards are removed after the concrete is completely set. This type of pile made on site can only be used on construction sites. It has low efficiency and poor air tightness, and is greatly affected by the climate. Nowadays, prefabricated piles that can be mass-produced are mostly used. The addition of prefabricated piles has significantly improved construction efficiency, but the height of prefabricated piles is limited. Inserting a prefabricated pile sometimes cannot reach the required height for construction, and multiple prefabricated piles need to be superimposed on each other. The existing splicing methods include welding and anchoring. The calibration of these two methods is relatively low, especially in harsh environments. The construction difficulty is increased and the construction efficiency is low. Moreover, the formed square piles are not easy to cut, which does not meet the construction requirements and also affects the appearance of the construction. Utility Model Content
