Floor flooring sundries is cleared up, and cleaning completes that subsequent pouring construction can be carried out after examination passes through；
(7) diamond dust wearing layer concreting:
The wear-resisting layer concrete of diamond dust uses C35 pea gravel concreten, configures 6 150mm reinforced mesh of single-layer bidirectional Φ；Diamond dust
Wearing layer ground starts to carry out secondary pouring construction after main structure is basically completed, with a thickness of 60mm, at the beginning of pea gravel concreten
It coagulates and spills diamond dust aggregate 5kg/ ㎡, placing and troweling light when reaching respective strengths standard；50-60% is dry before pea gravel concreten initial set
When, spreading aggregate makes every effort to that spreading is uniform, and spreading carries out in two times, and guarantees dosage；Specific practice is as follows:
1) laitance is removed, first time cloth: dispenses the diamond dust of specified volume 2/3 when 50-60% is dry before pea gravel concreten initial set,
It is compacted rub hair with the hands with disk sander, diamond dust is made to penetrate into concrete surface layer；
2) thin portion is levelling, second of cloth: first time cloth complete and complete thin portion it is levelling after again by residue 1/3 diamond dust according to
Sample dispenses, and cooperates disk sander and metal trowel entirety powder light；
3) mechanical trowel operation: view concrete hardening situation carries out at least vane type sanding machine polishing operation three times；
4) surface detail polishing operation: final to be completed the process using mechanical trowel or manual trowel surface；
5) it conserves: applying curing agent on the diamond dust wearing layer ground for thrown light and conserved, conserved depending on weather condition,
Curing time is no less than 7 days.
7. a kind of anchoring type according to claim 6 is secondary to pour diamond dust abrasion-resistant ground construction technology, it is characterised in that:
When spreading diamond dust aggregate Specific construction, it should also be noted that following main points: dispense before according to can construction area area and ground into
It spends situation and calculates spreading material utilization amount, every square metre of spreading 5kg avoids dosage insufficient or waste；Specified volume is dispensed for the first time
2/3 wear-resistant material be spread in uniform in the concrete surface in pre-hardening stage by hand, dehydration is local faster, such as close to template, vertical
Column, doorway, wall, pit etc. should be dispensed first；When material absorbs concrete surface moisture and darkens, carry out for the first time
Install the mechanical polishing operation of disk additional, disk processing less than place polishing operation by hand because moisture can be secreted out, this
Process is not required to plus water-wet profit；And then middle ware every other hour, can then carry out the spreading of surplus material, material can be made to fill in this way
Divide sorbent surface not and the moisture of evaporation；When material absorbs moisture and darkens, second of mechanical mill for installing disk additional is carried out
Light operation secretes moisture completely out.
