The New Construction Project of Anji County Future Sci-Tech City Experimental School and the National Fitness Center Construction Project are key livelihood projects that the Future Sci-Tech City area focuses on building. Their coordinated layout will inject diverse vitality into regional development.

The new experimental school project centers on creating a modern educational environment, with a total construction area of 63,762㎡, of which 47,286㎡ above ground is planned into five functional zones: the middle school area, primary school area, shared axis central area, multi-functional lecture hall and specialized classrooms, administrative office building, and library.Each area is relatively independent yet organically connected, with a maximum building height of about 19.760m, showcasing a simple and grand campus style; the underground 16,476㎡ centrally houses equipment rooms and underground parking facilities, providing solid support for efficient campus operation. 

The National Fitness Center construction project focuses on the fitness needs of all citizens, with a total construction area of 15,722㎡, of which 13,562㎡ above ground covers functional spaces such as a swimming pool, indoor sports arena, and cafeteria, meeting the fitness and supporting needs of different groups. The highest point of the building reaches 20.20m, displaying a dynamic and modern sports architectural style; the underground 2,160㎡ integrates equipment rooms and underground parking areas, improving the logistics service system.

Rotary drilled piles: 1,036; retaining piles: 182; high-pressure jet grouting piles: 1,465; slope protection: 10,560 square meters; anti-floating anchors: 942.

Rock and soil are broken by rotation using a bucket drill with a bottom flap. The soil is loaded into the drilling bucket, lifted out of the hole by the rig's lifting device and telescopic drill pipe, and discharged. This cycle repeats until the design depth is reached.

Using rotary drilling rigs, the mechanization level is high, and hole formation is fast. It can adapt to various strata (such as clay, sand, rock, etc.), greatly shortening the construction period.

Compared with traditional mud slurry wall protection, rotary drilled piles use dry operation or environmentally friendly mud, resulting in less mud discharge and minimal impact on the surrounding environment.

The hole formation process causes little disturbance to the hole wall, making the lowering of reinforcement cages and concrete pouring smoother, ensuring the integrity and strength of the pile body and improving the bearing performance of the pile foundation.

When developing underground space, to ensure the stability of the foundation pit, the safety of operations within the pit, control the displacement of soil at the bottom and outside the pit, and ensure the normal use of adjacent buildings and municipal facilities, piles are installed around the foundation pit, including gravity-type mixing pile retaining walls, diaphragm walls, and pile-row retaining walls, etc., serving the functions of earth retention and water cutoff.

As a foundation pit support structure, it can effectively prevent soil collapse outside the pit. Combined with a water cutoff curtain (such as in conjunction with high-pressure jet grouting piles), it achieves water cutoff, creating a safe space for construction within the pit.

With various forms (such as bored cast-in-place piles, steel sheet piles, etc.), it can be flexibly selected according to pit depth, geological conditions, and surrounding environment to meet different engineering needs.

Through reasonable design and construction, it can control foundation pit deformation, reduce the impact on surrounding buildings, roads, and underground pipelines, and ensure the safety of the surrounding environment during construction.

The equipment is compact, small in size, highly mobile, and occupies little space, making it suitable for construction in narrow areas; it can be used adjacent to existing buildings with minimal disturbance to the surroundings.

It can mix with soil to form a cement-soil reinforced body, improving the shear strength of the foundation and the properties of the soil. It has both earth retention and water cutoff functions and is commonly used for foundation reinforcement and foundation pit seepage prevention.

It can be used in various soft soil layers (such as silt, silty soil, etc.) and can control the reinforcement range to specifically address foundation defects.

Rod-shaped elements used to reinforce or anchor in-situ soil on site. A soil nail wall system consists of a group of soil nails, the reinforced in-situ soil, steel wire mesh, and a concrete facing.

Soil nails extend deep into the slope soil and, through friction and bonding with the soil, actively enhance slope stability, keeping the slope surface stable after excavation and preventing landslides and collapses.

The construction equipment is simple (such as small drilling rigs), the process is few, no large support structures are required, and the cost is low; construction is fast, quickly completing slope reinforcement and shortening the construction period.
