1) plate is along the axis of the slope used in comparing is to seize the elder brother, brother is only general gyro shape and amplitude or < standard width for sheet pile elder brother is processed according to the actual inclination and slope is relatively small; with the winch or hoist rope and the reverse drag the exercise.
2) pull the wind is to enter the ground elevation and burial depth must meet the "pull anything long more than 2 times the length is close to rectangular, roast pull the wind" file (body bending oath large 1 258 "degree is long) cannot be used.
3）钢板都受到石块等过程中侧向挤压作用力大小容易发生偏斜，措施的错误：发生的倾斜位置的钢板上拔去。0m ~ 2.0m再往下锤들어。这样上下往复振拔，而大的块石豪打破或文件位置发生偏移，钢板的市政减少钢板件。
3) the size of the lateral extrusion force in the process of the steel plate is inclined to be inclined, and the error of the measure: the inclination of the steel plate is pulled out. 0m ~ 2.0m to hammer. This up and down the uplift, and stone big ho break or file location shift, reduce the plate of steel city.
4) before dismantling the cofferdam, it is necessary to re - sand and flat the cofferdam to remove the cofferdam.
5) steel plate is the injection process, sometimes encounter a stone or other unknown obstacles to reduce the plate is to enter the depth of the problem, the use of curved angle is or obstacles.
6) where the foundation is soft, sometimes occurs. The construction of a neighbor is a temporary phenomenon to take measures to be adjacent to several kinds of welding together, and with the lock file connection point 588, butter and other lubricating economy to reduce resistance.
7) enclosure is a very "cool phone, check the" cool water. If the core is found, the openings of the steel sheet pile to reduce the leakage and the leakage of mud in the gap. Check the level of the purlin joint support, installation meets the design requirements. After all inspection and preparation of the dam body after a comprehensive examination of the rear can be carried out within the cofferdam dredging.
