Scope

Scope: This collection of drawings is applicable to bolt-lock type pre-stressed concrete solid-shaped special square piles (hereinafter referred to as bolt-lock solid-shaped special square piles), which are suitable for low-pile foundation applications in civil and industrial buildings and structures in areas with seismic fortification intensity of 8 degrees and below. They can also be referenced for use in railway, highway, bridge, port, municipal, and water conservancy projects, but they must still comply with the requirements of relevant specifications and regulations. The bolt-lock solid-shaped special square piles in this collection are primarily used to withstand vertical compressive loads and vertical uplift loads due to their concave and convex outer shapes and the use of bolt-lock mechanical connections. When subjected to horizontal loads, designers should consider factors such as geotechnical conditions, load magnitude, and construction conditions, and select or design accordingly through calculation and analysis. These piles are suitable for concrete structures with environmental classifications of Type I and Type II. When the concrete environmental classification is Type III to Type V, effective anti-corrosion measures should be taken on the pile body in accordance with relevant standards such as the *Standard for Corrosion Protection Design of Industrial Buildings* (GB/T 50046), and these measures should be specified in the design documents. Corrosion protection measures should also be implemented on the pile tips and joints. The design service life of these piles is 50 years.
