Embodiment Construction

[0034] According to the requirements of dyke seepage control design, three cone-head pressure grooved plates and pressure grooved equipment are used to form continuous grooves in the dams and foundations that need anti-seepage reinforcement; two-component expansibility is injected into the grooves through a grouting pipe Polymer grouting material; the volume of the polymer grouting material expands rapidly after chemical reaction, fills the slots and solidifies to form a polymer sheet; the polymer sheets of adjacent slots are tightly glued together , To form a continuous, uniform and regular ultra-thin polymer anti-seepage wall, so as to achieve the purpose of improving the anti-seepage performance of the dam.

[0035] The specific implementation steps are:

[0036] (1) Slot hole arrangement: In the dam body and foundation that need anti-seepage reinforcement, the slot holes are arranged according to the design, and the slot holes are numbered.

[0037] (2) Slot hole construction: u...

Abstract

The invention discloses a grouting method for an ultrathin high polymer cutoff wall, wherein continuous groove holes are constructed and formed in a dam and a foundation required to be turned into anti-seepage and consolidated according to the anti-seepage design requirement of the dam; two-component dilatant high polymer grouting materials are grouted into the groove holes through a grouting pipe; the high polymer grouting materials are quickly dilated after chemical reaction, then fill the groove holes to the brim and are solidified to form high polymer thin slice bodies, and the thin slice bodies in the neighboring groove holes are closely bonded, so as to form the continuous, uniform and regular ultrathin high polymer cutoff wall. The invention is highly distinct from the existing technology of the cutoff wall in aspects as material, mechanism, construction method and the like, has advantages of being quick, ultrathin, mini-wound, light, highly tenacious, economic, durable and the like, is successfully applied to multiple risk-removing consolidating projects of reservoir dams and embankment, and has huge economic and social benefits as well as wide development and application prospects.

Description

Technical field [0001] The invention belongs to the technical field of seepage prevention and reinforcement of infrastructure such as water conservancy, mining, environmental protection, etc., and specifically relates to an anti-seepage reinforcement ultra-thin polymer anti-seepage wall grouting method such as earth embankments, earth dams, tailings dams, and sewage interception dams. Background technique [0002] Since the founding of the People’s Republic of China, my country’s water conservancy, mining, environmental protection and other infrastructure construction has achieved world-renowned achievements, which have played an important role in my country’s economic development and social progress. In terms of water conservancy infrastructure construction, since most of my country's water conservancy facilities were built in the 1950s and 1970s, due to the economic and technical conditions at that time, many reservoirs were "inherently insufficient" in the design and constructi...
