Supplementary: the board is a type of float, it is shaped like a straight plate, the shape of the container, and the shape of the Z shape, and each type is large and long.
For the main purpose of the construction, the water supply process, the course of the water, the way of carrying the road, and the control of the price. In front of the construction, it is a four vessel seal that is the end of the construction. I come in contact with you.
The separate driving method is to start from one corner of the slab wall and set it block by block (or two blocks as a group) until the end of the project. The utility model has the advantages of simple and rapid construction and no need for other auxiliary supports.
Its disadvantage is that the sheet pile is easy to tilt to one side, and it is not easy to correct after error accumulation. Therefore, play it alone λ The method is only applicable to the case where the requirements for sheet pile wall are not high and the length of sheet pile is small (e.g. less than 10m).
When driving, first drive the steel sheet piles at both ends of the screen wall to the design elevation or a certain depth to become positioning sheet piles, and then drive them in steps according to the height of Ⅳ 3 and 1 / 2 sheet piles in the middle.
The advantage of screen driving method is that it can reduce the accumulation of inclination error, prevent excessive inclination, and is easy to realize closed closure, which can ensure the construction quality of sheet pile wall.
The disadvantage is that the self-supporting height of the inserted pile is large, and attention should be paid to the stability and construction safety of the inserted pile
During piling, the driving position and direction of the first and second steel sheet piles to be driven shall ensure accuracy, which can play the role of template guidance. Generally, it shall be measured every 1m driven.
Special shaped sheet pile, connector method, lap joint method and axis adjustment method can be adopted for the corner and closed closure construction of steel sheet pile.
To ensure safe construction, pay attention to the observation and protection of important pipelines and high-voltage cables within the operation scope.
When backfilling the foundation pit, the steel sheet pile shall be pulled out for reuse after trimming. Before removal, the removal sequence, removal time and pile hole treatment method of steel sheet pile shall be studied.
In order to overcome the resistance of sheet pile, according to the pile pulling machinery used, the pile pulling methods include static pile pulling, vibration pile pulling and impact pile pulling. During the removal operation, pay attention to observe and protect the important pipelines and high-voltage cables within the operation range.
Steel sheet pile is in line with the above three points: the elements of its manufacturing components provide a simple and practical structure, meet all the requirements of structural safety and environmental protection, and the buildings completed by steel sheet pile are very attractive
The application of steel sheet pile runs through and extends to the whole construction industry, from the use of traditional hydraulic engineering and civil technology and through the application of railway and tram track to the application of environmental pollution control.
The practical value of steel sheet pile has been reflected in the innovative production of many new products, such as some special welded buildings;
Metal plate made by hydraulic vibratory pile driver; Seal bonded sluice and factory coating treatment.
Many factors ensure that the steel sheet pile maintains one of the most useful manufacturing component elements, that is, it is not only conducive to the excellence of steel quality,
It is also conducive to the investigation, research and development of steel sheet pile Market;
It is conducive to the optimal design of product characteristics to better meet the needs of users.
The development of special sealing and printing process is a good example in this regard. For example, Hoesch patent system, its emergence has created an important new field of steel sheet pile in pollution control.
