Chinese Professional Trench Box Depth - Hydraulic Tunnel Linning Trolley – Lianggong Detail:
Product Details
Designed and developed by our own company, hydraulic tunnel lining trolley is an ideal system for formwork lining of railway and highway tunnels. Driven by electrical motors, it is able to move and walk by itself, with hydraulic cylinder and screw jack being used to position and retrieve the formwork. The trolley has many advantages in operation, such as low cost, reliable structure, convenient operation, fast lining speed and good tunnel surface.
The trolley is generally designed as a steel arch type, using a standard combined steel template, without automatic walking, using external power to drag, and the detachment template is all manually operated, which is labor-intensive. This type of lining trolley is generally used for short tunnel construction, especially for tunnel concrete lining construction with complex plane and space geometry, frequent process conversion, and strict process requirements. Its advantages are more obvious. The second tunnel reinforced concrete lining adopts a simple arch frame design, which solves these problems well, and at the same time, the engineering cost is low. Most of the simple trolleys use artificial concrete pouring, and the simple lining trolley is filled with concrete conveying pump trucks, so the rigidity of the trolley should be particularly strengthened. Some simple lining trolleys also use integral Steel Formwork, but they still use threaded rods and do not move automatically. This type of trolley is generally filled with concrete delivery pump trucks. Simple lining trolleys generally use combined steel formwork. Combined steel formwork is generally made of thin plates.
The rigidity of the steel formwork should be considered in the design process, so the spacing between steel arches should not be too large. If the length of the steel formwork is 1.5m, the average spacing between the steel arches should not be greater than 0.75m, and the longitudinal joint of the steel formwork should be set between the push and the push to facilitate the installation of formwork fasteners and formwork hooks. If the pump is used for infusion, the infusion speed should not be too fast, otherwise it will cause deformation of the composite steel formwork, especially when the lining thickness is greater than 500mm, the infusion speed should be slowed down. Be careful when capping and pouring. Pay attention to the pouring of concrete at all times to prevent the concrete pouring after filling, otherwise it will cause mold explosion or deformation of the trolley.
