Description
Technical field
The present invention relates to one kind to smear band seepage resistant material, relates in particular to one kind by " cement+fine sand+asbestos+water does not leak "
The novel Large Diameter Pipeline pipe of concrete of four kinds of basic materials composition smears carrying material.
Background technique
In the construction of town road Large Diameter Pipeline pipe of concrete, the waterproof of carrying material is smeared, impermeability directly affects Large Diameter Pipeline and mixes
The construction quality of solidifying soil pipe, then will affect the normal use of pipe of concrete upper layer structures.Traditional " cement+fine sand " is smeared
During carrying material uses, water proof anti-seepage is ineffective, and pipeline closed-water test percent of pass is low.How to improve and smears the impervious of carrying material
Waterproof performance is that municipal works Large Diameter Pipeline pipe of concrete smears key link in belt construction.Currently, the country's generally use " cement+
Fine sand+asbestos+waterproofing agent " is used to smear carrying material, with traditional " cement+fine sand " smear carrying material compared with, impervious effect has one
It is fixed to be promoted, but since the match ratio of material therefor is uncertain, waterproof overall effect is bad.
Asbestos are also known as " asbestos fibre ", are the general name that can split into the filametntary certain silicate minerals of high resilience, change
Formula: 3MgO2SiO22H2O, in threadiness.Water does not leak mainly by super absorbent resin (Super Absorbent
Polymer it) forms, is a kind of efficiently moisture-proof, impervious plugging material, it is list which, which is divided to rapid-hardening and two kinds of retardation setting type,
Component grey powder.
Consider for these reasons, the invention patent is by determining by " cement+fine sand+asbestos+water does not leak " four kinds of materials
The match ratio of composition reduces the seepage rate of Large Diameter Pipeline pipe of concrete seam crossing, the service life of pipeline is improved, to reduce pipeline
Maintenance cost.
