Description
Technical field
The invention belongs to building walls to protect field, and in particular to a kind of rammed earth city wall surface prevents rain drop erosion and weathering
Guard method.
Background technique
Ancient Chinese and liquidus semi-continuous casting mostly use rammed earth, brick, stone and wood to build, most of ancient buildings due to
Of the remote past, as the time of rain drop erosion or weathering extends, many historical relics face the risk seriously destroyed.Such as Great Wall and
Existing many city walls only remain rammed earth since city-wall brick is destroyed, and the ability for bearing rain drop erosion and weathering of rammed earth is much smaller than city
Wall brick, so needing to take city wall special protection means.With protect purpose not by salvo is also different.Some
The lesser city wall of antique value, scientist is generally by the way of packet brick reparation, but this mode changes city wall appearance.Have
A little biggish city walls of antique value, scientists wish to detect its material composition, do not require the monnolithic case for seeing city wall, can be with
Additional reinforcement device is built to protect city wall.The biggish city wall of some historic significances, scientists wish to keep its existing whole
External looks shape does not build accessory building or ornament arbitrarily in city wall in order to people's viewing in appearance.
In the prior art, have using isolation cabinet the method that prevents historical relic from destroying by environmental factor, but city wall volume
Greatly, length is long, is not suitable for the mode of isolation cabinet.Also there is using auxiliary device the guard method for reinforcing rammed earth city wall, use is auxiliary
Although the destruction of rain drop erosion and weathering to city wall can be effectively reduced after helping device, it can be seen that the appearance of original city wall, this
To archaeological work person detect city wall material composition it is significantly advantageous, but auxiliary device be it is tangible, will affect the sight of viewer,
Existing many city walls, for people's review history and viewing, if reinforcing using auxiliary device, understand shadow only as landscape
Ring the global shape viewing of city wall.In order to protect gradually destruction of the city wall not by rain drop erosion and wind erosion, it would be desirable to open again
A kind of neither influence city wall global shape viewing is sent out, and the side that gradually destroys of the city wall not by rain drop erosion and wind erosion can be protected
Method.
Summary of the invention
The object of the present invention is to provide the guard method that a kind of rammed earth city wall surface prevents rain drop erosion and weathering, this method
City wall wall is handled using liquid reagent, increases its anti-rain drop erosion and wind erosion performance, and after wall drying, city wall overall appearance
Form is simultaneously unchanged.
A kind of rammed earth city wall surface provided by the invention prevents the guard method of rain drop erosion and weathering, including following step
It is rapid:
Step 1 clears up surface of wall surface dust and sundries；
Step 2, surface of wall spray metal ion chelation agent solution, and keep surface of wall wet；
Step 3, surface of wall dry after surface of wall spray glutinous rice water, in wall after surface of wall dries again
External coating protective layer；
The protective layer is made of the raw material components of following parts by weight: 100 parts of grog water, 10~20 parts of oily matter,
0.1~0.5 part of emulsifier；The oily matter is vegetable oil or industrial grade white oil.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, the metal ion-chelant
Agent solution is sodium potassium tartrate tetrahydrate, ethylenediamine tetra-acetic acid or ammonium citrate.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, the metal ion-chelant
The concentration of agent solution is 0.1~2g/L.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, and the emulsifier is sorb
Acid alcohol or lauric monoglyceride.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, step 2 metal ion
The number that chelating agent solution soaks surface of wall is 1~3 time, and step 3 is to spray glutinous rice in the surface of wall dried for the last time
Water.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, the grog water according to
Following methods preparation: will be sufficiently dry after clay high pressure sterilization, grog is obtained, it is spare；By grog and deionized water according to
The mass ratio of 1:2~5 mixes, and stirs 10~20min, stands more than for 24 hours, takes supernatant liquid as grog water, spare；Under
Layer sediment is spare after collecting and drying.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, further comprising the steps of:
Slope is repaired at 0~5m of city wall, ground and city wall surface is made to the angle ranging from 120~150 degree.
Preferably, above-mentioned rammed earth city wall surface prevents the guard method of rain drop erosion and weathering, further comprising the steps of,
The setting isolation greenbelt at 10~15m of city wall.
Compared with prior art, rammed earth city wall provided by the invention surface prevents the guard method of rain drop erosion and weathering extremely
It has the advantages that less
1, the raw material used in view of rammed earth city wall is clay, wherein containing metal ions such as a large amount of calcium, iron, magnesium, aluminium, this
Invention can be by the metal ion network of these in soil altogether using metal ion chelation agent, the stable chelate of forming properties,
Increase the structural stability of city wall substance from molecular structure level；Since the enzyme effect of most microorganisms needs the metals such as magnesium, calcium
The participation of ion can inhibit enzyme to act on after chelating agent, reduce microorganism in environment and break to rammed earth city wall surface
It is bad.Glutinous rice water of the present invention has viscosity, loose soil can be made to be bonded, and glutinous rice water is that natural materials are prepared, to environment
It is pollution-free.Protective layer of the present invention has hydrophobicity and viscosity, not only wall substance can be made to combine closely, and can make rain
Water is short in rammed earth city wall superficial residence time, can reduce rainwater to the osmotic damage on city wall surface.
2, method of the invention handles rammed earth city wall wall using liquid reagent, increases its anti-rain drop erosion and weathering
Can, and after wall drying, city wall overall appearance form is simultaneously unchanged, can save for a long time, meets landscape and watches demand.
3, simulation test statistics indicate that: by different wind and rain conditions processing after, the thickness loss amount of conventional loam wall is
0.01mm and 4.12mm；After the method processing metope for testing wall 1~4, metope loss amount reduced to 0.003 and 2.69~
2.78mm illustrates that rain drop erosion damage caused by rammed earth city wall surface can be effectively prevented in method of the invention.
