Abstract

The invention provides a comprehensive technology and a construction method of planted roof engineering, and relates to single roof greening with the area being 100-5000 square meters and underground engineering square greening with the area being 10 000-100 000 square meters. Because the technical requirement that no water is accumulated on large-area square greening during a rainstorm is not distinguished in standards, many defects exist. According to the comprehensive technology and the construction method of the planted roof engineering, slope making is conducted on an underground engineering top plate with the area being 10 000-100 000 square meters; rainwater on an upper building roof, walls and road surfaces is distributed and recycled; as for drainage of greening percolating water, flat plastic plates are arranged on the upper portion of supporting points of edges, and water discharging smoothness is guaranteed; the left, right, front and back of each roll polyethylene or polypropylene drain plate are welded thermally or bond through adhesive tape to achieve root penetrating resistance and an auxiliary waterproof function; the self-adhesive plastic drain plates are used, the shapes of the supporting points are changed, compressive strength is enhanced, the drain plates adhere to the walls, and therefore one object has multiple functions, construction cost is reduced, and overall quality of the engineering is improved.

Description

The comprehensive technology of planted roof and construction method

Technical field

The invention belongs to building planted roof greening scope, relate generally to the underground construction square greening of the roof greening of 100～5000 squares of monomers and monomer 10,000～100,000 square, in this total invention of general designation planted roof, comprise that square looks for that slope, rainwater shunting recycle, delivery port is strengthened, band drain connects and reaches root-resistant puncturing and auxiliary waterproof action, on metope, turn over node, change fulcrum shape and improve the multinomial independent claims such as compressive strength.

Background technology

Current specifications has < < planted roof tecnical regulations > > JGJ155-2007; Root resistant waterproof roll > > JC/T1075-2008 for < < planted roof; < < Technical code for water proof in underground engineering > > GB50108-2008.These standards content related to the present invention be mainly summarized as following some:

1. the top board of GB50108 code requirement square greening is that structure is looked for slope 1%～2%, it is considered herein that this cannot implement, and proposes other technologies scheme.

2. JGJ155 rules do not propose the draining difference of square greening and roof greening, the present invention proposes that the rainwater of square greening shunt, recycled, during heavy rain without the technical scheme of ponding and delivery port reinforcement.

3. to require one deck be topmost root-resistant puncturing waterproofing course to rules, and the present invention connects the left-right and front-back of plastics web-like band drain to reach sealing firmly, has the waterproof action of root-resistant puncturing, can one-object-many-purposes way, reduce cost, and improve engineering total quality.

Summary of the invention

During my design of the underground construction top board square greening in many monomer area 1～100,000 square drainage grade, find that architect has no way of doing it, its reason is that < < Technical code for water proof in underground engineering > > claimed structure is looked for slope, and the gradient is preferably 1%～2%.I propose through case summary: basement structure top board is level, and with concrete etc., looking for slope material is 30～50cm scope in overall height, completes top board draining look for slope with part plan, the local gradient.More than look for slope way only to relate to square greening, do not relate to the roof greening of small size.

Many buildings and Large Square are arranged at underground construction top board top, can not ponding during heavy rain, and the draining of therefore classifying is very important theory, but in current specifications, there is no this idea.I go out by case summary: the rain water on roof of top board upper building, metope rainwater, road rain water are entered to pipeline tissue and discharge, can enter reservoir, by rainwater cycling and reutilization, solved the rainwater flow on 20%～60% square, also improved the ability of the anti-heavy rain in city simultaneously.Remaining rainwater is that top board top greening infiltration rainwater filters through geotextiles, from the surface of plastic draining board, discharge, be pooled to underground construction edge and enter underground water or urban drainage pipe network, the wide plastic board of sticky paving one deck 3～30cm on the fulcrum of edge band drain, cover again geotextiles, geotextiles is not sunk, guarantee that draining is forever unimpeded.

The pressure clause Shi“ the superiors of < < planted roof tecnical regulations > > must use root-resistant puncturing waterproofing materials " I have the plastic draining board of hollow fulcrum to have good water resistance with polyethylene or polyacrylic web-like, key is that the connection of left-right and front-back is reached to the examination criteria of root resistant waterproof roll > > for < < planted roof, can superimposed hot weld and normal temperature under butyl adhesive tape bonding.Heat weldable way is: during production, the left and right of band drain is stayed to the wide flat board of 50～150mm, during construction, with climbing welding machine by the superimposed hot weld of plastic board, weld seam has one or two; The front and back of band drain are fulcrums, superimposed 1～5 row's fulcrum, and with welding gun or customization special hot welding tool, by the flat limit hot weld between fulcrum, weld seam has one or two.

The bonding way of adhesive tape is: during production, in the left and right of band drain, squeeze into one to four adhesive tape, can also can have multiple combination mode at the right and left monolateral, become self-adhesion plastic draining board.Mutual plane cementation laminated or take fulcrum cementation laminated during construction; The self-adhesive coiled material of the multiple butyl rubber of the wide polyethylene sheets of 50～100mm for front and back, is bonded in the plane of band drain.For the fastness of seam before and after strengthening, then with the wide self-adhesive coiled material of 6～20mm, cover in seam on seam.Front and back are bonding, can also overlap row's fulcrum, then it are bonding to add adhesive tape.All adhesive tape add chemical root resistance agent when producing, and can improve root-resistant puncturing effect, and adhesive tape outside has release liners to cover.

Hot weld and splicing can also be combined: about when band drain is produced, stay 50～150mm dull and stereotyped, superimposed hot weld, weld seam has one or two; Front and back are bonded in the plane of band drain with the wide self-adhesive coiled material of 50～100mm, or overlap row's fulcrum, then it is bonding to add adhesive tape.

Because the plastic draining board of planted roof is on waterproofing course, when band drain reaches the quality specifications of root-resistant puncturing, just can protect waterproofing course, reduce engineering cost, improve the waterproof quality time limit.

Plastic draining board all around after sealed attachment, on band drain, turn over and lean against on metope, then be bonded at wall upper cover outside band drain fulcrum with the wide self-adhesive coiled material of 50～200mm, or band drain plane is pasted on the wall, then geotextiles is bonded to the top of band drain, then earthing.

In order to improve the compressive strength of band drain fulcrum, the present invention changes into square, polygon, prismatic by the fulcrum of garden frustum shape, and there is the shape of concavo-convex ribbed stiffener side.
