Description
Technical field
The utility model is related to a kind of road earth material constructing device, and in particular to quick to a kind of broad place insulation material
Draw off gear.
Background technology
According to《Rolling earth-rock dam job specfication》(DL/T5129-2013) and relevant regulations, should when temperature is less than 0 DEG C
Stopping earth material, which is constructed and taken, slows down the earth material filled in storehouse face to prevent there is frozen soil phenomenon after covering and heat insulating measure, insulation, therefore
The subzero temperature period will directly affect clay core wall of earth dam and fill the duration.Conventional earth material Winter protection measure is that covering insulation material is carried out
Protection, this method can effectively alleviate the construction quality influence that earth material is endured cold brought.The river mouth Hydropower Project of Yalongjiang River two is located in
East Side of Qinghai-Xizang Plateau edge zone, category west Sichuan plateau climatic province, many average temperatures of the whole year are 10.9 DEG C, and extreme maximum temperature is 35.9
DEG C, Annual lowest climate temperature is -15.9 DEG C, and March annual November to next year is the winter of this area.Winter temperature is relatively low, lowest temperature
Degree is concentrated mainly on December~January next year then, January 1.8 DEG C of samming, no permafrost, daily 23:00 to next day 11:00 is
The subzero temperature period.The engineering winter construction period is up to 5 wheat harvesting periods, and Annual lowest climate temperature is relatively low, therefore carrying out covering and heat insulating measure is
It is highly important.Winter day and night temperature is larger, and the low temperature period part soil body can endure cold and containing ice crystal, ice crystal is heated after noon heating
It can typically melt, the soil body is then subjected to frozen-thaw process.Two river mouths power station be the straight core wall rockfill dam of gravelly soil, height of dam 295m, wherein
The clay core wall of earth dam gravelly soil design amount of filling 441.14 ten thousand m3, contact clay 17.96 ten thousand m3, it is 1.56 ten thousand that average every layer, which is filled area,
㎡, peak period reaches 2 Wan Duo ㎡, and the winter construction side of filling amount reaches 1,280,000 m3, account for the 28% of core wall filling building earth material.At present should
Engineering is carried out using the geomembrane of " film of three cloth two " depending on earth material insulation covering protection, temperature of the construction period with scene, temperature
Recover construction during higher than 0 DEG C, stop construction during less than 0 DEG C.The current ㎡ of core wall filling building area about 8000, is matched somebody with somebody using conventional forklift
Close artificial progress and receive anti-geomembrane, geotechnological film quality is about 1kg or so per square meter, due to the artificial folding and unfolding geotechnique using routine
Film, so every piece of geomembrane is cut into size for 20m × 6m.25 people and 1 forklift is needed to coordinate when receiving geomembrane, it is 2 small
When complete receive geomembrane work.30 people and 1 forklift are needed when putting geomembrane, putting the time of geomembrane needs 3 hours.But have daily
The earth material engineering time of limit is 10 hours or so, therefore in order to the maximized engineering time using the lower earth material of positive temperature, scene
Postponed in the presence of receipts geomembrane time advance and covering geomembrane time, cause outside air temperature when less than 0 DEG C, earth material is not covered,
Earth material insulation is not affected by guarantee.Coordinate the destruction carried to geomembrane larger using forklift, cause recycling rate of waterused relatively low, and
Every piece of geomembrane size is smaller, and overall heat insulation effect is relatively low, it is necessary to consume a large amount of artificial, labor intensity is big, time length, expense
Height, easily wastes the positive temperature construction period limited daily, it is impossible to meet quick continuous productive process requirement.Current China's planning is with building
High earth and rockfill dam is more, is largely located in High aititude, extremely frigid zones, such as double Jiangkou, the Milin projects in Tibet, core wall filling building side's amount
Greatly, the problem of there is winter construction, can in 1 year if winter stopping construction, it is considered to fill influence of the rainy season on precordial distress
Less using the period of constructing, construction phase of project will be very long, it is considered to financial cost, and engineering efficiency will be severely impacted.
