Abstract

A novel waterproof isolator is characterized by being formed by a reactive inorganic material and a hydrophobic organic high molecular material, wherein the reactive inorganic material is formed by fly ash and quicklime powder, and the content (weight percentage) of the quicklime powder is 10-35 percent; and the hydrophobic organic high molecular material is formed by a polystyrene foamed plastic particle. The invention has the beneficial effects that in a moist pit or a low-lying field, the reactive inorganic material is bedded below the hydrophobic organic high molecular material; and after the reactive inorganic material with a thickness of 10-50 cm is firstly used for bedding, and the surface of the reactive inorganic material is slightly leveled and compacted, the polystyrene foamed plastic with a thickness of 10-40 cm is bedded on the reactive inorganic material, so that a capillary pore channel in soil can be effectively cut off to block the upward migration and diffusion of water.

Description

A kind of novel blocking water used isolator

Technical field

The invention belongs to civil engineering material technical field, relate to a kind of novel blocking water and use isolator.

Background technology

Soil is a kind of hydrophilic material; Infiltration and diffusion very easily take place in moisture in this material. and the infiltration motion has taken place through the various pore channels in the soil in hydrone; Its result moist phenomenon occurs on the top layer of soil, or a large amount of water soakings of after water evaporates occurring on the face of land, leaving over.For avoiding moist phenomenon on the face of land, occurring; The conventional rule of doing is a lay desiccant on the face of land; Blot tiny moisture with desiccant, and prevailing way is used as desiccant with quicklime or fine grinding quicklime powder exactly by soil internal penetration table section to ground.Process result so, following period of time can reach the effect that the face of land is kept dry state in the early stage.Can clear up reaction after the lime suction and become hydrated lime.Hydrated lime will form the interconnected pore of a lot of opening shapes within it in portion's structure after calcium hydroxide crystallization and excessive moisture evaporation take place in inside.Because calcium hydroxide itself also is a kind of hydrophilic material, therefore, the underground water in the soil still can continue to cause the dampness of hydrated lime laminar surface through upwards diffusion of the hole in the hydrated lime at this moment.Therefore, adopt quicklime to be actually unsuccessful as face of land desiccant.

According to retrieval; Patent of invention (publication number 1113933), (publication number 1194175) and (publication number 1094054) are introduced all is that a kind of water in air that is used for absorbing local zonule drying of dividing use material, can't stop the phreatic diffusive migration that makes progress.Patent of invention " osmotic waterproofing agent, material water-proof material, concrete or mortar composition, and the method that prevents seepage " (publication number 1246138) provides a kind of waterproofing agent that can use and have good block-water performance in a simple manner.Its mechanism of action is that this material can penetrate into and causes in the crack or hole that leaks, thereby fills this slit to prevent that water is from seepage wherein.Yet this disclosed waterproofing agent in fact just is exclusively used in a kind of patching material on the building, can not stop the upwards diffusive migration along capillary porosity duct in the soil of moisture in the soil at all.

Summary of the invention

The objective of the invention is to deficiency, a kind of novel composite water-stopping isolating agent is provided, make it to have the buffer action that well blocks water, effectively stop upwards infiltration diffusion of underground moisture to prior art.

For realizing such purpose, in the technical scheme of the present invention, water-stopping isolating agent is made up of two types of materials.One type is the response type inorganic material, and another kind of is the hydrophobicity high-molecular organic material.The response type inorganic material is made up of flyash and calcium lime powder, and wherein the content of calcium lime powder (percentage by weight) is 10 %-, 35 %, and the hydrophobicity high-molecular organic material then is made up of the polystyrene foaming type plastic grain.

The specific embodimentDuring use, response type inorganic material place mat is under the hydrophobicity high-molecular organic material.In the heatable adobe sleeping platform or low-lying land of humidity, lay the groundwork earlier with the response type inorganic material, THICKNESS CONTROL is at 10-50cm, slightly as the surface shakeout with compacting after, upper berth polystyrene foaming type plastic grain, thickness are 10-40cm.

After underground water upwards is diffused in the compound of flyash and calcium lime powder; Slaking reaction at first takes place in calcium lime powder; The active silica generation chemical reaction of the calcium hydroxide that reaction generates under the state of humidity and in the flyash generates hydrated calcium silicate gel.The mutual adhesion of this gel becomes as a whole, and progressively becomes the comparatively solid plate with certain intensity.Capillary porosity duct in this tight ground of plate shutoff soil all absorbs those underground water that permeate up, and refusal moisture is upwards diffusion easily, self takes place the necessary condition of chemical reaction to this part moisture as making again simultaneously.The styrofoam particle that is layered on the upper strata is a kind of hydrophobic material, plays effectively to cut off hydrone infiltration road, and underground water the upwards diffusion chance is here got rid of fully.Like this, the article of in the zone on the foamed plastic stratum granulosum, placing just can be in the dried state of a kind of gas all the time, and can not receive interference and the infiltration from underground percolating water again.

Composite water-stopping isolating agent of the present invention has the good buffer action that blocks water, and can effectively cut off the capillary porosity duct in the soil, stops the moisture diffusion mobility that makes progress.With soil in moisture upwards lay the directed scattering and permeating that this material can effectively stop moisture on the perpendicular in-plane of the channel direction of infiltration, and the other end keeps the dried state of gas, eliminates moist phenomenon.
