Larsen steel piles are widely used in municipal water conservancy projects and municipal sewage projects. However, this year, due to the irregular operation of many construction teams, there is no strict compliance with the construction of Larsen steel sheet piles during the construction of Larsen steel sheet piles. To the construction of the construction to bring a lot of trouble, then we come to the following Larsen steel sheet construction knowledge, especially in the construction of municipal water conservancy construction Larsen steel sheet pile tolerance range and municipal water conservancy construction steel sheet pile of attention Two big points.
First，the municipal water conservancy construction in the Larsen steel sheet pile to allow the scope of the deviation is:
1、on the axis position, land piling allowable deviation of 100 mm, water piling allowable deviation of 200 mm.
2、on the top elevation, land piling allowable deviation of the size of not more than 100 mm, water piling allowable deviation of the size of not more than 200 mm.
3、on the vertical stiffness of steel sheet, each 100 mm long steel sheet pile vertical deviation of not more than 100 mm.
Second, the municipal water conservancy construction steel sheet pile Note:
1、steel pile pile for sticky soil, sand, silt and other weak strata.
2、steel sheet pile for shallow depth of the support structure.
3、before the piling must be clear the removal of underground, ground and high-altitude obstacles, the need to retain the underground pipeline should be exposed and protected.
4、the foundation pit and structure during construction, the foundation pit and support system for dynamic observation. Find the problem, timely processing.
5、after the excavation of the steel sheet pile vertical and smooth, no serious distortion, tilt and splitting phenomenon, lock mouth tightly connected.
6、steel sheet pile laying construction, pile head in place must be correct, vertical, pile pile process, at any time detection, found the problem, timely processing.
The above is on the municipal water conservancy construction in the Larsen steel sheet pile allowable deviation range and municipal water conservancy construction steel sheet pile of the details of the details, if not strictly in accordance with the provisions of the construction, then the substandard steel sheet pile project, so also There will be a lot of security risks.
