Description
Technical field
The present invention relates to a kind of cellular concrete barricade and build maintaining method, relating in particular to a kind of for preventing the cellular concrete barricade of mud-stone flow disaster and building maintaining method.
Background technology
Slope, is seen everywhere in China, distributes extremely extensive.But the natural calamity that cause on slope, as landslide and mud-rock flow etc., often sudden strong, harmfulness is large, especially in densely populated Hong Kong, Shenzhen, Chongqing etc.The disaster that cause on slope not only causes huge property loss, also can cause a tremendous loss of lives.The method of preventing and treating of the disaster that at present, cause on slope has two classes: initiatively protection and passive protection.Initiatively protection is to stop in advance slope to produce landslide, mud-stone flow disaster, as sets antislide pile etc.Passive protection is in the generation that allows disaster, but avoids disaster to work the mischief.Initiatively protection is because control area is large, and expense is huge, is often used in that slope is less and particular importance is regional.Passive control is widely used in slope treatment because cost is low and efficiency is high.In passive control, halfway sliding mass or mud-rock flow etc. being tackled is a kind of effectively safeguard procedures.The features such as motion path based on sliding mass and mud-rock flow, sliding rate, slippage scope, barricade is used to tackle sliding mass and mud-rock flow etc., to ensure property and life security in guard plot.
Gabion baffling is a kind of common passive protection barricade.Because its price is relatively cheap, in intercept process, distortion greatly, absorbs energy large, in passive protection, is widely used.But gabion baffling wire is easy to corrosion, long-term behaviour is not good, and later maintenance expense is larger.Gabion baffling needs large-scale stone, brings challenges to transport and the carrying in the mountain area of complicated condition.And for building after calamity, gabion baffling often needs to reconstruct again, the construction time is long, has increased the disaster-stricken risk in urban conservation area.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of for preventing the cellular concrete barricade of mud-stone flow disaster and building maintaining method.
A kind of for preventing the cellular concrete barricade of mud-stone flow disaster, for the control of landslide, described massif has slope, it is characterized in that: describedly comprise cellular concrete and stone cut off wall for the cellular concrete barricade that prevents mud-stone flow disaster, described stone cut off wall be provided with meet domatic, it is domatic that described cellular concrete is cast in meeting of stone cut off wall, described cellular concrete by bubble, cement, aggregate and water through mixing, wherein said bubble adopts blowing agent to make, described for preventing the cellular concrete dams setting of mud-stone flow disaster under toe of a slope.
Further, described maximum aggregate size is 5mm.
Further, described stone cut off wall is rigidity stone cut off wall, and the thickness of described stone cut off wall is 0.2m to 2m.
Further, the thickness of described cellular concrete is 0.2 to 1m, and the height of described cellular concrete is identical with stone cut off wall height.
Further, described cellular concrete is mixed by bubble, cement, aggregate and water, and the ratio of described bubble, cement, aggregate is bubble: cement: aggregate is about 700L:330kg:1200kg.
Further, described cement adopts Portland cement, and its strength grade is not less than 32.5.
Further, described aggregate adopts one or more of on-the-spot soil, building castoff or mud-rock flow relict soil/Shi Tizhong.
Further, the mobility of described cellular concrete is 160 to 190mm, and moist unit weight is 5 to 13 kN/m
3, air capacity 20 to 70%, 28 days unconfined compression strengths 0.5 to 2MPa.
For preventing the construction maintaining method of cellular concrete barricade for mud-stone flow disaster, comprise the following steps,
The first step: build stone cut off wall;
Second step: leveling stone cut off wall is met domatic ground, builds the template for building cellular concrete;
The 3rd step: mix bubble, cement, aggregate and water, prepare standard compliant cellular concrete;
The 4th step: adopt pumping equipment that the cellular concrete of new system is delivered in template;
The 5th step: maintain certain humidity, maintenance cellular concrete is after 28 days, stripping.
Compared to prior art, cellular concrete stone cut off wall of the present invention is taking cellular concrete as power consumption material, and institute's aggregate that adopts is originated extensively, can gather materials on the spot, and maybe can adopt building castoff, low-carbon environment-friendly; Cellular concrete barricade has stronger corrosion resistance, and long-term behaviour is good, and later maintenance expense is low; Cellular concrete is macrovoid material, has reduced construction price; The distortion when soil body clashes into is large, even broken, and power consumption significantly; Cellular concrete stream plasticity is good, and easy construction is especially applicable to the rugged complex conditions that waits of physical features; Stand after disaster, only need cellular concrete to repair, and aggregate can adopt landslide or the mud-rock flow soil body, convenience, simple, quick.
Brief description of the drawings
Fig. 1 is of the present invention for preventing the structural representation of cellular concrete barricade of mud-stone flow disaster.
Detailed description of the invention
Below in conjunction with brief description of the drawings and detailed description of the invention, the present invention is further described.
Refer to Fig. 1, the invention provides a kind of for preventing the cellular concrete barricade of mud-stone flow disaster and building maintaining method.Described for preventing the cellular concrete barricade of mud-stone flow disaster to build in 1 underfooting, slope near zone of protection 5 places.Specifically, for preventing the cellular concrete barricade of mud-stone flow disaster to build between 1 underfooting, slope and zone of protection 5.
