Mine anti-fouling and anti-seepage treatment method for waste incineration fly ash treatment and anti-seepage layer
The invention provides a mine anti-fouling and anti-seepage treatment method for waste incineration fly ash treatment and an anti-seepage layer. The mine anti-fouling and anti-seepage treatment method for waste incineration fly ash treatment comprises the steps that: step 3, a water gushing channel is subjected to grouting plugging through aggregate gelling grout; step 4, the water seepage channel is subjected to splitting grouting plugging through aggregate-free gelling grout; and step 5, carrying out anti-seepage treatment on a semicircular arched roadway of the mine, wherein the specific process of anti-seepage treatment comprises the steps: firstly, spraying an anti-seepage concrete mixture on the surface of the wall of the semicircular arched roadway of the original mine at a high speed by using compressed air through a spray gun to form a first concrete anti-seepage layer, and then paving a clay liner on the first concrete anti-seepage layer, and tightly connecting the clay liner with the first concrete anti-seepage layer through anchoring pins; and then spraying the anti-seepage concrete mixture to the clay liner, and forming a second concrete anti-seepage layer. By means of the mode that the two concrete anti-seepage layers are laid in the roadway and the GCL geosynthetic clay liner is clamped between the two concrete anti-seepage layers, the effects of anti-seepage, dirt isolation and secondary supporting are achieved.
本发明提供了一种用于垃圾焚烧飞灰处置的矿井防污防渗处理方法及防渗层，包括：步骤3，对于涌水通道采用骨料胶凝浆液进行注浆封堵；步骤4，对于渗水通道采用无骨料胶凝浆液进行劈裂法注浆封堵；步骤5，对矿井的半圆拱形巷道进行防渗处理：防渗处理的具体过程包括：首先，用压缩空气将防渗混凝土拌合料经喷枪高速喷射于原矿井的半圆拱形巷道壁的表面，形成第一道混凝土防渗层，然后在第一道混凝土防渗层上铺设防水毯，通过锚固销将防水毯与第一道混凝土防渗层紧密连接；再向防水毯喷射防渗混凝土拌合料，形成第二道混凝土防渗层。本发明利用在巷道内部铺设两道混凝土防渗层夹一道GCL膨润土防水毯的方式，达到防渗隔污和二次支护的效果。
