Electroosmosis seepage-preventing and damp-preventing method utilizing ground as negative electrode and applying to underground space

Abstract

The invention provides an electroosmosis seepage-preventing and damp-preventing method utilizing the ground as the negative electrode and applying to underground space. According to the method, holes are drilled in a grounded wall isolated by rocks or soil at intervals, a positive electrode material is arranged in each drilled hole, a closed circuit is formed with the negative electrode area of the ground, a rectification and current stabilization converter is connected to each positive electrode material through a wire, 220 V alternating currents are output and rectified through the converter, converted into direct currents through the converter and supplied to the positive electrode materials, the grounded wall makes contact with the rectified positive electrode materials, the currents are output by a power supply, flow through the positive electrode materials, reach the grounded wall in the positive electrode material area and finally flow to the negative electrode area of the rocks or soil, water molecules in the grounded wall are led to the negative electrode area by making contact with the wall positively charged, and therefore the surface of the grounded wall can keep dry; meanwhile, free water in the rocks or soil are migrated to the negative electrode area under the effect of positive electrode and negative electrode electric fields, and therefore seepage and damp can be prevented.

Description

technical field [0001] The invention relates to the technical field of moisture-proof and seepage-proof (water) in underground engineering of buildings, in particular to an earth-negative electrode-type underground space electroosmotic seepage-proof and moisture-proof method suitable for basement moisture-proof and seepage-proof. Background technique [0002] The use of electroosmosis technology is a new technology for anti-seepage and moisture-proof underground engineering in recent years, and has been successfully applied to new projects or construction projects that have not completed decoration. However, in the current technology, the positive electrode material needs to be laid in the isolation wall, the use of multiple electrode materials is large, the construction is complicated, and the project cost is high.

Problems solved by technology

However, in the current technology, the positive electrode material needs to be laid in the isolation wall, the use of multiple electrode materials is large, the construction is complicated, and the project cost is high. Due to the need to slot and embed the positive electrode material, and then drill The negative electrode is buried through the wallboard to the rock and soil body. Therefore, for the completed decoration project, the renovated part needs to be removed to complete the laying of the electrode. Especially for the underground space where tiles or marble are laid, the main problems are as follows:

[0003] (1) Removal of existing decoration materials such as ceramic tiles and marbles, the processing cost is high, the maintenance cost is expensive, and it is also a great waste for the entire project activity;

[0004] (2) The electroosmotic instruments currently used in China are mainly from Norway, and the price is expensive, 10,000-20,000 per unit;

[0005] (3) A large amount of electrode materials need to be laid, and the project cost is high;

[0006] (4) It is necessary to drill and install a large number of negative electrodes on the concrete wall or ground, and the construction is difficult and complicated
