Construction and installation of waterstops
Waterstops are partially or completely buried in the concrete during the concrete pouring process. There are many sharp stones and sharp steel heads in the concrete. Since the tear strength of plastic and rubber is lower than the tensile strength, once the waterstop is punctured or torn, the crack will expand without a large external force. Therefore, during the process of waterstop positioning and concrete pouring, , attention should be paid to the positioning method and pouring pressure to prevent the waterstop from being punctured. Therefore, during the positioning of the waterstop and concrete pouring, attention should be paid to the positioning method and pouring pressure to prevent the waterstop from being punctured and affecting the waterstop. Water effect, specific precautions are as follows
The waterstop should not be exposed to the sun for a long time, prevent rain, and do not come into contact with highly polluting chemicals.
During transportation and construction, prevent machinery and steel bars from damaging the waterstop.
During the construction process, the waterstop must be reliably fixed to avoid displacement when pouring concrete and ensure the correct position of the waterstop in the concrete.
Methods for fixing the waterstop include using additional steel bars to fix special fixtures to fix lead wires and templates. If perforation is required, it can only be installed in the edge installation area of the waterstop, and other parts must not be damaged.
When ordering, users should calculate the length of the product based on the engineering structure and design drawings. Special-shaped structures should have drawing instructions. Try to connect the waterstops as a whole in the factory. If you need to connect them on site, you can use electric heating plates. Methods of vulcanization bonding or cold bonding (rubber waterstop) or welding (plastic waterstop)
Yesterday was a range-bound consolidation trend. Looking at the minute chart, the line fluctuates up and down around the short- and medium-term averages, and the upward trend of the short- and medium-term average lines has obviously stagnated. From the daily chart, the technical indicators have crossed downwards, and the lines have seen a cross star adjustment. The technical indicators still maintain a bullish upward trend. Compared with the previous trading day, the trading volume has increased significantly, and the open interest has basically decreased slightly compared with the previous day.
