The most common method is to use the side of the culvert construction method to support the small steel sheet pile. Before the construction of the first side of the drainage side of the culvert of the geological survey, with excavators by digging the location of the seepage layer and elevation measurement.
In the Larsen steel piles municipal sewage construction before the first side of the drainage side of the culvert of the geological survey, with excavators digging by digging the location of the seepage layer and elevation measurement.
Larsen steel sheet piles municipal sewage construction specific steps to determine the groundwater location, to determine the drainage side of the culvert, and then can dig earth, followed by playing Larsen steel sheet pile, excavation base, geotextile jamming flow sand, cushion, floor steel, Template installation, floor concrete, covered with steel, template reinforcement, culvert concrete backfill.
Specific construction should pay attention to: before the construction or to check the Larsen steel sheet pile, the use of single pile into the method, the first pile piles hanging piling points, plug in the lock when the lock, each insert a piece, then put the pile The cap is gently hammered. If there is a gap or the gap between the mouth part of the gap, with a width greater than or less than the standard width of the special plate pile can be corrected.
Larsen sheet pile piling precautions: stacking should pay attention to the order of stacking, location, direction and layout should take into account the subsequent construction convenience, steel piles according to the type, size, length were stacked, and set up in the stack sign The In addition, the Rikai basic engineering proposal steel sheet pile should be layered stacking, the number of stacking each layer is generally not more than 5, the layers to pillow sleepers, mat spacing is generally 3-4 meters, and the upper and lower pad wood should be in the same vertical Online, the total height of the stack should not exceed 2 meters.
Larsen steel sheet pile lifting Note: loading and unloading steel sheet pile should use two hanging. When lifting, the number of steel piles per lifting should not be too much, and should pay attention to protect the lock from damage. There are bundled lifting and single lifting. Bundle lifting is usually tied with steel, and a single crane commonly used special spreader.
