Description

A kind of the whitewashing slurry and its shotcrete construction method of concrete base layer
Technical field
The invention belongs to the realm of building construction, and in particular to one kind is used for concrete base layer shotcrete construction technique.
Background technique
Whitewashing is that automatically or semi-automatically slurry is directly injected to the construction technology in work surface by pulp shooting machine using mortar, spray Slurry slurry is usually to be configured by boundary mortar and water.Shotcrete construction is carried out primarily to preventing metope to concrete base layer Hollowing.Cement and sand are saved since concrete ejection technology has, labour is saved, improves construction efficiency, reduce engineering cost The features such as, application prospect is boundless.Although however, shotcrete construction has formd certain professional standard, current slurry Material and construction method are difficult to ensure adhesive force of the slurry in base, have seriously affected the construction quality of shotcrete construction.To understand Certainly this problem, unit in charge of construction need to handle base repeatedly, and can be carried out whitewashing at the acceptance(check) rear of high standard and apply Work, to guarantee to obtain expected construction quality.Not only it took time and effort, but also improves construction cost, while it is also possible to work can be delayed Phase is disagreed with using the original intention of shotcrete construction.
Summary of the invention
Goal of the invention: a kind of for concrete base layer whitewashing present invention aims in view of the deficiencies of the prior art, providing The slurry of construction;A kind of method carrying out shotcrete construction using the slurry is provided simultaneously.
Technical solution: the whitewashing slurry of concrete base layer of the present invention, including base pastes and surface layer slurry;
The base pastes include following component:
The surface layer slurry includes following component:
80~100 parts of boundary mortar;
0.3~0.8 part of traction-resistant fibre;
10~20 parts of water, each component is in parts by weight.
Further preferably technical solution is the present invention, and the base pastes include following component:
The surface layer slurry includes following component:
90 parts of boundary mortar;
0.6 part of traction-resistant fibre;
12 parts of water, each component is in parts by weight.
Preferably, the foaming agent in the base pastes is modified saponin foaming agent.
Preferably, the consistency of the base pastes is 80~100mm.
Preferably, the traction-resistant fibre in the surface layer slurry is polypropylene fibre.
Preferably, the consistency of the surface layer slurry is 90~100mm.
Preferably, bonding glue is 801 glue.
Slurry of the present invention carries out shotcrete construction method, includes the following steps:
(1) concrete base layer surface is cleared up, mending concrete substrate surface defect, concrete base layer is kept wet before whitewashing Profit;
(2) using mortar, automatically or semi-automatically pulp shooting machine forms bottom in concrete base layer surface even application base pastes Layer gunite layer;
(3) surface of bottom gunite layer is spread into matte, waits the initial set of bottom gunite layer;
(4) bottom gunite layer initial set after, using mortar automatically or semi-automatically pulp shooting machine bottom whitewashing layer surface uniformly spray Surface layer slurry is applied, surface layer gunite layer is formed;
(5) levelling surface layer gunite layer carries out metope maintenance, completes shotcrete construction.
Further, it before step (2) sprayed layer undercoat slurry, needs to carry out examination spray, specific steps are as follows: choose at least 10 The concrete base layer surface of ㎡ is as examination spray position;Using mortar, automatically or semi-automatically pulp shooting machine is trying spray position sprayed layer undercoat slurry Material, with dotted or web form uniform fold examination spray position;The thickness of base pastes of observation examination spray position covering, consistency, just Whether the adhesion effect of solidifying time and itself and concrete base layer reaches design requirement, sprays after meeting the requirements to concrete base layer Priming operation slurry.
The utility model has the advantages that whitewashing slurry of the invention includes base pastes and surface layer slurry, base pastes caking property is good, can be with Guarantee the good adhesion effect between concrete base layer, can be sprayed, be not necessarily to after only need to simply clearing up concrete base layer It is cumbersome that base is strictly handled, without carrying out an acceptance inspection, a large amount of construction time is saved, is shortened the construction period, surface layer slurry It is sprayed on base pastes, improves base pastes because the defects of water-resisting property caused by the requirement of high adhesion force is poor, prevents metope Hollowing;In addition construction method of the invention meets industry construction reference, meets construction quality while the duration is greatly shortened Requirement.
