Classification of steel sheet piles
Steel sheet pile cofferdam is a kind of commonly used sheet pile cofferdam. Steel sheet pile is a kind of section steel with lock mouth. Its section includes straight plate
Steel sheet pile is a kind of steel structure with linkage device at the edge, which can be freely combined to form a continuous and tight retaining wall or water retaining wall.
Classification of common steel sheet piles:
Larsen steel sheet pile

Larsen steel sheet pile is divided into cold bent steel sheet pile and hot rolled steel sheet pile.
Steel sheet pile cofferdam is a kind of commonly used sheet pile cofferdam. Steel sheet pile is a kind of section steel with lock mouth. Its section includes straight plate, groove and Z shape, and has various sizes and interlocking forms. The common ones are Larsen style, Lakvanna style, etc.
Its advantages are: high strength, easy to drive into hard soil; It can be constructed in deep water, and if necessary, diagonal bracing can be added to form an enclosure. Good waterproof performance; Cofferdams of various shapes can be formed as required and can be reused for many times. Therefore, they are widely used.
In bridge construction, it is often used as cofferdam at the top of open caisson, which is widely used. Cofferdams for pipe column foundation, pile foundation and open cut foundation.
These cofferdams are mostly of single wall closed type. There are longitudinal and transverse supports in the cofferdams. If necessary, diagonal supports are added to form a cofferdam. For example, the steel sheet pile circular cofferdam was used for the pipe column foundation of the Nanjing Yangtze River Bridge in China, with a diameter of 21.9m and a length of 36m. There are various sizes and interlocking forms. When the underwater concrete bottom sealing meets the strength requirements, pump water to build the cushion cap and pier shaft, and the design depth of pumping water is 20m.
In hydraulic buildings, the construction area is generally large, so it is often used to make structural cofferdams. It is composed of many interconnected monomer, each monomer is composed of many steel sheet piles, and the middle of the monomer is filled with soil. The cofferdam covers a large area and cannot support the weir wall with supports. Therefore, each individual can independently resist overturning, sliding and tension cracking at the interlock. Commonly used are round and partition shaped.
The following are the more effective geotechnical engineering and application environment for some common steel sheet piles:
*Flood diversion and control of river channel
*Water treatment system fence
*Tunnel incision and tunnel shelter
Advantages of using steel sheet pile fence:
*If necessary, the steel sheet pile can be pulled out after use
*Not affected by topography and deep groundwater
*Irregular excavation can be used
*You can work on the ship without arranging another siteTurn left | turn right
Steel sheet piles
On the evening of January 22, 2016, Tangshan Yunfeng held the 2016 year-end conference ceremoniously. The wine is full of fragrance, singing and dancing, and the atmosphere is lively.
After more than 10 years of hard exploration and more than 3 years of construction in our country, the celebration ceremony for the completion and operation of Shenhua Ningxia Coal Industry Group's coal to liquids demonstration project was held on the 28th in the coal to liquids project area of Ningdong Energy and Chemical Base in the suburb of Yinchuan, Ningxia
Warm congratulations on the grand opening of Tangshan Yunfeng Fengrun Branch
In 2016, Tangshan Yunfeng Industry and Trade Co., Ltd. joined hands with Tianjin Mingfa Municipal Government to create a one-stop service of steel sheet pile sales and piling. Tianjin Mingfa Municipal Engineering Co., Ltd. is a well-known pile driving engineering company in Tianjin
Thank the leaders of Jinxi Group for their warm hospitality and selfless help over the years, and congratulate the Ningxia Iron and Steel Association on its successful visit to Tangshan Yunfeng and Jinxi Group
Tangshan Yunfeng recently established a new welding H steel structure engineering department, which can undertake various steel structure projects and also provide various welding H steel for major steel structure projects
