Founded in 2010, Lianggong Formwork is a reputable Chinese manufacturer specializing in the R&D, production and global supply of premium trench shoring, formwork and scaffolding products. Our core offerings, LG-T100 Standard Trench Box and LG Slide Rail Shoring, deliver reliable, cost-effective trench safety solutions for municipal pipeline construction, foundation excavation and all kinds of underground trenching projects worldwide. Engineered against international construction safety standards, our shoring systems effectively prevent trench collapse, eliminate burial hazards and optimize overall construction efficiency.
What Are Key Features of Lianggong Trench Shoring System?
1. LG-T100 Standard Trench Box
As our flagship trench safety product, the LG-T100 trench box is the preferred shoring option for excavation depths up to 4 meters, with a theoretical stacked installation depth cap of 6 meters. Available in mainstream sizes including 1.3m×4.5m and 2.6m×4.5m, it features a maximum working height of 1500mm and flexible adjustable working width to fit diverse trench dimensions.
Key Advantages:
● Superior onsite safety: Reinforced panel structure withstands lateral earth pressure, avoiding fatal cave-in risks for construction crews inside trenches;
● Flexible installation: Supports two mature construction techniques: Place & Adjust Method and Cut & Lower Method, adaptable to stable and unstable geological conditions respectively;
● Economical construction: Cuts excess earth excavation, backfilling and compaction workloads, greatly lowering total pipeline project expenditure (trench shoring normally accounts for around 33% of total pipe construction cost).
Application Scenarios:
Ideal for narrow, long ditch excavation and pipeline laying; replaces costly sheet pile shoring when ground sloping is impractical. Slope adaptability varies by soil: compatible with stable soil (53° slope) and unstable soil (34° slope) with enclosed shoring protection.
2. LG Slide Rail Shoring
Custom-designed for deep trenching over 4 meters, LG Slide Rail Shoring features built-in slide rails and overcomes the structural deformation shortcoming of stacked trench boxes. Unlike conventional trench boxes which deform into parallelograms and change width during lifting or extraction, each component slides independently while staying parallel, maintaining fixed shoring width throughout installation and removal. It drastically reduces pulling friction induced by increased earth pressure at greater depths, making it the optimal deep-trench shoring solution.
What Are Critical Selection Factors for Shoring Solutions?
We conduct customized shoring configuration based on comprehensive site survey covering: trench depth & terrain topography, soil texture, underground water level, extra loads from adjacent buildings/vehicular traffic, as well as pipeline diameter and laying clearance requirements. Earth pressure rises proportionally with trench depth, while longer shoring panels bear reduced allowable earth load in quadratic relation—our technical team performs professional stress analysis calculation to match product specification with actual site load conditions.
Why Choose Lianggong As Your Trench Shoring System Supplier?
