Diaphragm wall STOP END ELEMENT MAIN FEATURES
Why use a diaphragm wall stop end ?
During production of cast in situ concrete diaphragm walls, the most important factor, especially to achieve a watertight joint, will be the use of the right stop end elements. They contain the concrete on the lateral side meanwhile they create a particular casting profile that offers a high seal against water infiltration.
Diaphragm wall stop end  have two type , one is diaphragm wall flat stop end , another is diaphragm wall round stop end pipe
Diaphragm wall Stop End Elements are coupled together through special steel shafts even better special o-ring ensure a perfect seal between the areas of the diaphragm.
Diaphragm wall flat stop end are coupled with steel shafts , materials:42Crmo
 They are made of sheet metal welded and its special profile is achieved by a process of press bending and finally an internal reinforcing structure increases its strength and avoids the risk of deformation.
The excavation of a follow-up panel is carried out by clamshell grab, with the help of a special flat chisel if needed, both guided by the channel in the pipe. While digging, these tools clean the exposed side of the pipe. The  design of the Stop End Elements, and its constructive characteristics, allows a spontaneous lateral movement after the excavation, making a delayed extraction very easy. The continuity of two following panels is guaranteed even in the presence of small vertical deviations, because the excavation is guided along the stop end element. With this method as opposed to other working system, there is no urgency to remove the stop end element. It can be left in place for days or even weeks before extraction. A water stop can be added to the stop-end element to improve water tightness between joints. For this purpose, a special rubber seal will be mounted on the side of Stop End Element which will come into contact with the concrete. The lateral movement of the stop-end element during extraction leaves the water-stop fixed in the concrete. Tianjin huachang xingye technology co ltd  can supply diaphragm wall Stop End Elements in various widths and lengths. They are easily jointed each other through special steel. The Stop End Elements are: the diaphragm wall stop end lift head element that is used for their lifting and extraction, intermediate elements and bottom stop end elements. In addition, to facilitate the use of Stop End Elements,tianjin huachang xingye technology co.,ltd  manufactures diaphragm wall  chisel  (dedicated to the cleaning of the channel guide) and a Platform Suspension Jig (dedicated to the support of Stop End Element during installation)
