Larsen steel sheet pile cofferdam support which construction requirements

Views:2    

Larsen steel sheet pile cofferdam construction of the support in the installation of a very critical role, one side of the pumping side of the installation of internal support, pumping every 1m should be paused for a period of time, so that the support within the steady support, and Timely plugging. Here we come to a detailed description of the Larsen steel sheet pile cofferdam support which construction requirements?


Construction of Lusen Steel Sheet Pile Cofferdam


On the Rosen steel sheet pile cofferdam reinforcement, is to ensure the safety of the premise, the steel sheet pile cofferdam construction and cofferdam water level or mud surface decline according to the "first support after precipitation or suction, layered support Stratified precipitation or suction "principle. It can be said that the reinforcement of the steel sheet pile cofferdam is carried out around the support of the steel sheet pile cofferdam, from the order of reinforcement support can be seen.


Reinforcement of the support sequence: pumping to the first layer of support → plus the first layer of purlin and within the support → suction to the second layer of support → plus the second layer of purlin and internal support → suction to Foundation pit bottom. Steel plate pile purlin support, including purlin and internal support, the use of two-tier layout, two layers were 0.0m, -4.8m.

    

Larsen steel sheet pile cofferdam installation within the support of a considerable introduction of the technical requirements:

1、the installation of internal support to strictly control the quality of the weld;

2、within the support with the pump in time to install the elevation;

3、in strict accordance with the number of design support within the installation.


The above is the Larsen steel sheet pile cofferdam construction of the installation of the support must be strictly adhere to the three requirements, hoping to attract everyone's attention, so that your Larsen steel sheet pile cofferdam installation can reach a full 10 points.
