Description
(1) technical field
The utility model belongs to root system of plant stopping material research field, particularly a kind of novel root stopping material.
(2) background technology
Propelling along with urbanization process, all kinds of buildings in the city are built more and more, and green area is more and more littler, downtown area particularly, " heat island " phenomenon that is caused by highdensity architectural complex is on the rise, and afforestation of city has caused each side experts' such as urban planning, building, environment concern as the effective means of alleviating heat island effect.In urban development, build a large amount of high buildings and large mansions and have a kind of satisfactory to both parties situation that is difficult between the environment to improve with economic pursuit benefit and expansion green area.Building platform and roof greening (and at building platform and roof planting flower plant) then can solve this a kind of problem, and it is a kind of doulbe-sides' victory scheme, are considered to the developing direction that following ecological environment in metropolis and greening are built.
Planted roof should still be a newer things in China, is that material, construction and relevant laws and regulations aspect and some developed countries ratio all have bigger gap.Meanwhile, we must recognize that any planted roof is the same with other waterproofing all can face same stubborn problem---antiseep.Why thorny, a very important reason is that the complicated root system of plant can produce huge destructive power, thereby causes the collapse of whole roof waterproof system.The planted roof system has certain complexity, whole roofing tends to comprise a plurality of structures such as preparation soil layer, water-storage-drainage layer, waterproofing course, insulation layer, in case waterproof failure, whole roofing can only be rooted out rebuilding, and this consequence will be catastrophic, and this just need add the waterproofing materials of reliable quality anti-root penetration in system.
China lacks research and the production to the root stopping material in the past, means for the processing of root penetration problem, some local way is exactly to add the thick rigid waterproof layer of 40～60mm together on waterproofing course, wishes to carry out certain obstruction effect to the root of plant with this.But the strength that plant produced of well developed root system still can be destroyed layer of concrete, in addition concrete material itself almost can produce the crack, even last some destruction also can be caused catastrophic consequence.According to this way, add rigid waterproof layer at roofing, not only can not well play root resistance and waterproof action, also increased the bearing capacity on roof greatly.
The engineering that has is when planting bigger shrub and arbor, because fear penetration problem, simply adopted potted plant form, in the planted roof soil horizon, place container, be controlled at the root of plant in the container as far as possible, but such way still can't be guaranteed safety, because the hole of reserving and the existence in the slit of container own, the situation that rises and split has still appearred in many containers.
In a word, prevent that plant roots from penetrating, become the key of roof planting success or not, it is very necessary selecting suitable root stopping material on planted roof for use.
(3) summary of the invention
