Does Construction Waste Have This Magical Effect With A Screening Bucket?
2022-10-13
Muck is a kind of construction waste, which is widely produced in various demolition and reconstruction sites, mainly including spoil, waste materials and other wastes. With the continuous improvement of urban construction, the amount of muck produced in our country is large, and most of them are not used well, resulting in a great waste of resources.
Exploring more ways to recycle construction waste is an environmental problem that needs to be solved urgently in social development, and it is also a general trend in the future. So do you know what the magic of construction waste is? Today, the editor will introduce a method to let the muck exert its residual heat.
When introducing this method, we need to turn our attention to Ningbo, Zhejiang. Near the Olympic Sports Center, a Yichen screening bucket was installed on the excavator, and the muck was being processed. The job of the screening bucket is to sieve the stones and the slag, to crush the agglomerated slag, and then directly align the discharge port with the slag treatment equipment for subsequent operations.
The follow-up operation is actually very simple. By adding cement and other admixtures to the construction slag, a material with high fluidity, high self-confidence and high early strength is formed. This process has a professional name - the use of construction debris to make controllable low-strength materials, or CLSM for short.
This material can be used in the construction of pipe gallery. It can be poured by pumping, which can well solve the problem that it is difficult to backfill and compact in narrow spaces such as foundation pits and trenches. Compared with conventional backfill materials such as coarse sand and foamed soil, backfilling by CLSM utilizes construction waste and reduces the amount of waste disposal. At the same time, the use of this material for backfilling can reduce the uneven settlement of the road surface, which has great advantages in technology and economy, and has more significant social benefits.
In the Ningbo comprehensive pipe gallery project, the screening bucket processed a total of 800 cubic meters of construction waste, which provided great convenience for the manufacture of CLSM. It can be seen that the screening bucket has unparalleled advantages in the pre-treatment of construction waste.
