Problems solved by technology

[0006] In order to overcome the shallow penetration depth of reinforcement materials, poor air permeability after reinforcement, and no concentration gradient and strength gradient formed in the existing technology, it is easy to form a hard shell between the reinforced layer and the unreinforced layer on the surface of the earthen site, causing the entire reinforcement layer on the surface of the site to fall off problem, the present invention proposes a kind of anti-weather reinforcement agent for loess relics and its preparation and reinforcement method

Embodiment 1

[0063] The present embodiment is a loess site anti-weathering reinforcement and its preparation and reinforcement method. The test site is the non-relic area of ​​the Hanguangmen Site Museum of the Tanghuang City Wall in Xi'an City, Shaanxi Province.

[0064] The loess site weatherproof reinforcement material used in this example contains two types of reinforcements, CB-I and CB-II, of which the reinforcement agent CB-I is a non-ferrous compound prepared by dissolving 5 grams of oxalic acid and 1 milliliter of phosphoric acid in every 1000 milliliters of ethanol. Color clear solution; No. CB-II strengthening agent is a colorless clear solution in which 15 grams of barium hydroxide is dissolved in 2500 ml of methanol. The chemical raw materials are all industrially pure.

[0065] When preparing the above-mentioned loess site anti-weathering reinforcement, the following steps are included:

[0066] Step 1: Preparation of No. CB-I reinforcing agent: Dissolve 5 g of oxalic acid a...

Embodiment 2

[0073] This embodiment is a loess site anti-weathering reinforcement and its preparation and reinforcement method, and the test site is a non-relic area of ​​Xiadian Village, Chang'an County, Shaanxi Province. The moisture content of the test area was 5.12%.

[0074] The weatherproof reinforcement material used in the loess site in this example contains two types of reinforcements, CB-I and CB-II. Among them, No. CB-I reinforcement is made by dissolving 10 grams of oxalic acid and 5 milliliters of phosphoric acid in every 1000 milliliters of ethanol. It is formulated into a colorless and clear solution; CB-II strengthening agent is prepared by dissolving 50 grams of barium hydroxide in 2500 ml of methanol to prepare a colorless and clear solution. The chemical raw materials are all industrially pure.

[0075] When preparing the above-mentioned loess site anti-weathering reinforcement, the following steps are included:

[0076] Step 1: Preparation of No. CB-I reinforcing agen...

Embodiment 3

[0083] The present embodiment is a loess site anti-weathering reinforcement and its preparation and reinforcement method. The test site is a non-relic area in Xiadian Village, Chang'an County, Shaanxi Province, and the moisture content of the test area is 9.83%.

[0084]The loess site anti-weathering reinforcement material used in this example contains two types of reinforcements, CB-I and CB-II. Among them, the reinforcement agent CB-I is made by dissolving 15 grams of oxalic acid and 8 milliliters of phosphoric acid in 1000 milliliters of ethanol. It is formulated into a colorless and clear solution; CB-II strengthening agent is prepared by dissolving 90 grams of barium hydroxide in 2500 ml of methanol to prepare a colorless and clear solution. The chemical raw materials are all industrially pure.

[0085] When preparing the above-mentioned loess site anti-weathering reinforcement, the following steps are included:

[0086] Step 1: Preparation of No. CB-I Reinforcing Agent:...

Abstract

The invention relates to a loess relic efflorescence-proof reinforcing agent and a preparation and reinforcing method thereof. The method comprises the following steps: dissolving 5-25g of oxalate and 1-15ml of CB-I reinforcing agent prepared from phosphoric acid in every 1000ml of ethanol, and dissolving 15-150g of CB-II reingorcing agent prepared from barium hydroxide in every 2500ml of carbinol; and utilizing a dual reinforcing method of carrying out microprecipitation and adsorption on the losess relic by the CB-I reingorcing agent and the CB-II reingorcing agent, and utilizing a three-step dripping mode to achieve the reinforcing effect. By adopting the technical scheme of the invention, a loess relic efflorescence-proof reinforcing material and the reinforcing method which are suitable for dry, semi-dry and humid environment conditions of a semihumid area are obtained. The chemical raw materials of the invention are technical pure, and has the advantages of low cost, simple manufacturing process and reinforcing method, and easy operation, thereby having good market development prospect. After being processed by the loess relic efflorescence-proof reinforcing material of the invention according to the reinforcing method, the loess relic shows excellent reinforced effect.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection materials, in particular to a reinforcement material for protecting loess sites. Background technique [0002] The soil sites are the traces of production and life in a specific period left by the ancestors. They carry important historical and cultural information and have extremely important value for the research of ancient culture; however, the particularity of soil pan-alkali, weathering, water erosion and biological reproduction has caused Great difficulty in the protection of soil sites. At present, the diseases of soil sites are mainly affected by their own composition, structure and environmental factors, which make it difficult for the soil to maintain the water balance, and eventually lead to the decline of the bearing capacity after too much water absorption or the sandification of the soil after too much water loss. Therefore, the development of weatherproof reinfor...
