1. Basic Regulations Dense Pile Groups: Construction should proceed from the center outward symmetrically. Pile Groups Adjacent to Buildings: Construction should move from the building side to the opposite side.…
1. Project Overview 1.1 General Project Description The Nanchang Metro Line 4 Phase I Project (Civil Construction Section 2, Zone 3) includes: Bayuehu Road Station → Dingjiazhou Station Section Dingjiazhou Station Dingjiazhou…
Abstract This innovative construction technique utilizes chainsaw-type cutters to horizontally excavate, trench, grout, and mix with in-situ soil to create cement-soil walls. By incorporating more economical GZH high-strength support pipe…
Introduction In recent years, trench collapse accidents in construction have become a major concern for industry regulators. Due to site constraints, trenches are often excavated vertically, increasing the risk of…
1. Scope of Application This guide applies to the construction of cement deep mixing piles (CDM) for soft soil ground improvement, ensuring stability and load-bearing capacity. 2. Pre-Construction Preparation 2.1 Site Preparation Ensure "Three…
Soil nailing is a widely used reinforcement technique in excavation projects. It involves stabilizing slopes by installing steel-reinforced soil nails, followed by the application of a wire mesh and sprayed concrete…
What Is Foundation Pit Dewatering? Foundation pit dewatering refers to the process of lowering the groundwater level when excavating a foundation pit. If the water table is higher than the…
Introduction PHC (Prestressed High-strength Concrete) pipe piles are widely used in high-rise building foundations due to their high strength, rapid construction, and excellent load-bearing capacity. These piles significantly improve bearing…
