Problems solved by technology

[0003] The repair agent used for the maintenance or repair of travertine rock dams needs to focus on the maintenance of the original geological characteristics of travertine, but the maintenance or repair materials of conventional water conservancy project bank slopes such as reinforced concrete and travertine geological ecology Poor capacity, it is difficult to ensure that the color, density and permeability coefficient of travertine are consistent with the materials used for edge rock dam repair, resulting in the destruction of the original characteristics of travertine
For example, Chinese patent CN103526720 discloses a reinforced concrete prefabricated pile spur dam construction method, using reinforced concrete sheet piles as the spur dam foundation to replace the rockfill spur dam, which can maintain stability under the action of tidal surge and flood erosion, and can better withstand surge The impact of the tide, but the steel bars introduced to improve the stability of the reinforcement material will cause permanent damage to the original geomorphology

Abstract

The invention provides a repair agent for travertine geology. The repair agent is prepared from the following components in parts by weight: 65-87 parts of a travertine base material, 5-30 parts of lime and 1-5 parts of gypsum. According to the repair agent, the adopted travertine base material is good in compatibility with a repaired geological environment, so that in-situ repair of the travertine geology without damage and pollution is realized, and the repair efficiency and the strength after repairing are high. The repair agent can be used for repairing collapsed regions and large gaps of a stone dam at the edge of a ground surface colored pool in a travertine scenic spot, can also be used for repairing the travertine geology and is strong in pertinence. Shown by results of the embodiment of the invention, the provided repair agent for the travertine geology can realize in-situ repair of the travertine geology; and in the using process of the repair agent for the travertine geology, the compressive strength can reach 18 MPa.

Description

technical field [0001] The invention relates to the technical field of geological restoration, in particular to a repairing agent for travertine geology, a repairing liquid and the application of the repairing liquid. Background technique [0002] Travertine is a bicarbonate-rich surface water that, under suitable physical, chemical or biological conditions, is close to and / or exposed to the surface of the earth, forming a carbonate travertine deposit due to the escape of carbon dioxide in large quantities. These sediments change with the movement of the water flow and the change of the water circulation system, forming travertine landscapes, such as travertine side stone dam colored pools, travertine beach flows, travertine waterfalls and travertine collapse caves. As a special type of karst landform, while being continuously formed, it also faces the phenomenon of evolution and degradation of the landscape under the influence of normal erosion, among which the collapse or ...
