Water-stopping curtain construction method
The invention relates to the field of building construction, in particular to a water-stopping curtain and a construction method thereof. The water-stopping curtain construction method provided by the invention is characterized in that the method comprises the steps of 1) leveling a construction area and marking hole drilling positions according to a design drawing; 2) enabling a drilling machine to enter the construction area to perform construction, wherein the inclination of the drilling machine is required to be smaller than 1 percent; 3) immediately replacing mud in a drilled hole with a shelling material through a drill rod after the drilled hole is formed; 4) immediately inserting a sleeve valve pipe after replacement is completed, and lowering the sleeve valve pipe into the drilled hole till the sleeve valve pipe reaches the bottom of the drilled hole; 5) after at least 24 hours after the completion of the replacement step, grouting through a grouting inner pipe inserted into the sleeve valve pipe, and paying close attention to change of grouting pressure during grouting; 6) after grouting, sealing and protecting the mouth of the drilled hole by using a plug. The water-stopping curtain construction method provided by the invention can guarantee the water-stopping quality, effectively avoid the abnormal situations such as grout leaking and accelerate the construction progress.
