The critical link between tunnel waterproofing membrane installation in Guizhou and the related construction processes!

(1) Smooth blasting and initial support are fundamental processes. Although neither smooth blasting nor initial support falls under the scope of drainage system construction, they are closely linked to it. When smooth blasting achieves excellent results, circumferential spring drainage pipes can be installed smoothly along the surrounding rock surface. Moreover, if the initial support surface remains uniformly smooth (defined as having a ratio of vertical deviation to chord length ≤ 1/6 across irregularities), the step of locally leveling the surface before applying the waterproofing membrane in the Bijie Tunnel in Guizhou can be eliminated—while still ensuring reliable performance. Guizhou Bijie Tunnel Waterproof Board Adhering closely to the sprayed concrete surface, while ensuring proper spacing between each nail Guizhou Bijie Tunnel Waterproof Board The allowance for slack can be easily kept under reasonable control.
(2) All drainage pipes behind the lining must be carefully installed according to the design, following the principle of "prioritizing drainage while combining prevention and drainage," to ensure smooth water flow. This will help reduce the water pressure behind the secondary lining, thereby extending its service life. Guizhou Bijie Tunnel Waterproof Board Its service life achieves reliable waterproof performance.
(3) Before pouring the secondary lining concrete, it is essential to thoroughly clean away any loose debris from the sidewall base; otherwise, it may lead to uneven settlement of the tunnel lining and create weak spots at the concrete construction joints. Guizhou Bijie Tunnel Waterproof Board Easily torn apart.
(4) When pouring the secondary lining concrete, protective devices must be installed at the outlet of the delivery pump to prevent the material flow ejected from the discharge pipe from continuously striking the waterproof membrane of the Bijie Tunnel in Guizhou, which could otherwise result in damage. Guizhou Bijie Tunnel Waterproof Board Worn out.
