Description
Technical field
The present invention relates to a kind of construction techniques, particularly the construction method of the topping of highrise building inner base engineering waterproofing layer.
Background technology
Along with construction land is nervous gradually, highrise building must get more and more, and has the raft plate of waterproof requirement accordingly, base plate class foundation pattern also must get more and more; For these bases (as raft plate skew back face, elevator foundation pit skew back face and collecting well foundation ditch skew back face etc.), engineering design all requires add topping to waterproofing course, existing designing requirement is: overlay on existing waterproofing course one deck 50 thick C20 pea gravel concreten smear pressure levelling as topping; But find in work progress, if the waterproofing course laid in the horizontal plane adds pea gravel concreten topping, due to himself Action of Gravity Field, relatively easy operation, easily stable " surviving ", well can play the effect of protection waterproofing course; But be under the condition on >=45 degree of inclined-planes at waterproofing course, the difficulty of construction that existing inclined-plane waterproofing course lays pea gravel concreten topping is large, work progress is time-consuming, effort; Main difficulty is: 1, operation inclined-plane cannot provide safe and effective foothold, work plane, operating personnel need by special scaffold just can safely, operation smoothly, a but special scaffold, costly, poor universality, access times are few, sexual valence ratio; 2, the angle of slope when inclined-plane is larger, the more difficult stable operation of pea gravel concreten, effective " surviving ", and quality is also not easy to control, and the activity duration needed is longer, and labour cost is high; 3, most waterproofing course is hydrophobic material, and surperficial relative smooth, and pea gravel concreten topping and base adhesive power are not enough, easily come off, and causes waterproofing course to can not get good finished product protection; 4, pea gravel concreten topping belongs to " wetting " operation, and engineering quantity is comparatively large, and transport of materials is more difficult, input is larger; 5, pea gravel concreten at least needs the service time of 2 ~ 3 days, just can enter into lower step operation; The aggregate scheduling of foundation is had a certain impact.
Summary of the invention
The object of the present invention is to provide a kind of easy construction, save time, laborsaving, good to waterproofing course protection effect " foundation ditch inclined-plane waterproofing course topping construction method "; to solve under existing design and construction method at waterproofing course is the condition on >=45 degree of inclined-planes; the difficulty of construction that existing inclined-plane waterproofing course lays pea gravel concreten topping is large, the problem that work progress is time-consuming, effort, effect are bad.
The technical scheme solved the problem is: the construction method of the topping of a kind of foundation ditch inclined-plane waterproofing course; the method is on >=45 degree of foundation ditch waterproofing course inclined-planes; use galvanized sheet iron to substitute the construction method of conventional pea gravel concreten as the topping of waterproofing course, its concrete steps are:
A, topping are got the raw materials ready: by answering the metal skin of construction foundation pit waterproofing course inclined-plane area customization good-extensibility as topping;
B, on waterproofing course inclined-plane, paste topping: topping one side is applied bonding agent, is laid on outside inclined-plane waterproofing course;
C: prune and mend limit: undertaken pruning by on-site actual situations and use in Xi Bu lap-joint a small amount of galvanized sheet iron to mend limit.
Its further technical scheme is: the galvanized sheet of to be thickness the be 0.35 ~ 0.5mm of the metal skin as the good-extensibility of topping.
Its further technical scheme be: the bonding agent being coated in the topping back side is 502 glue.
Its further technical scheme or: the galvanized sheet of to be thickness the be 0.35 ~ 0.5mm of the metal skin as the good-extensibility of topping by splicing, then is used the sealing tape of 50 ~ 70mm width to paste to form, and during splicing, the every limit of galvanized sheet will overlap about 10mm.
Compared with prior art, the topping construction method of a kind of foundation ditch inclined-plane waterproofing course of the present invention has following beneficial effect:
1. easy construction, save time, laborsaving:
The present invention adopts galvanized sheet iron to substitute the topping of conventional pea gravel concreten as waterproofing course, has the advantages that secondary transhipment is convenient, lay is rapid, physical labor intensity is little, the feature of easily combining closely with basic unit's coiled material, also has to be easy to processing, cutting:
Galvanized steel plain sheet of the present invention refers to and plate zinc layers on cold-rolled steel sheet or hot rolled steel plate, and just obtain galvanized sheet, galvanized sheet is commonly called as tin plate, price: current 4000-5000 yuan/ton; In the present invention, galvanized sheet (tin plate) only uses (that is: after construction of waterproof layer completes as the topping of waterproofing course, before the reinforcing bars such as the raft plate of colligation on it or base plate, prevent reinforcing bar from transporting, scratch when putting, destroy waterproofing course), therefore its endurance quality can be considered; Can use the galvanized sheet (tin plate) that thickness about 0.35 ~ 0.5mm is thick, its specification is common is the wide drum of 1000mm*2000mm or 1000mm; Thickness is thin, has secondary transhipment convenience, lay is rapid, physical labor intensity is little, the feature that easy and basic unit's coiled material is combined closely, also have the feature being easy to processing, cutting.
2. this inclined-plane waterproof aspect does the construction method infusion of financial resources of topping less with galvanized sheet iron, simple to operate, man-hours requirement is few, does not at all destroy original structure, meets building energy conservation, low-carbon (LC) and economic and practical principle, requirement; A kind for the treatment of measures are provided for optimizing similar construction technology.
Be described further below in conjunction with the technical characteristic of drawings and Examples to the construction method of the topping of a kind of foundation ditch inclined-plane waterproofing course of the present invention.
