Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a decomposition system and decomposition method for high water content construction dregs, which are used to solve or partially solve the high water content and high viscosity of construction dregs, which make decomposition difficult. It is difficult to mix it evenly with the solidified material by using excavators and mixing stations on site. It needs to be dried and dehydrated before decomposing and mixing construction. It is greatly affected by the weather and has low work efficiency.

Embodiment 1

[0045] like Figure 1-4 As shown, the high-water content construction slag decomposition system includes a turning machine host, a turning device, an automatic material spreading system, a dust suction system, a spraying system and a control system.

[0046] like Figure 1-3 The main engine of the flipping machine shown includes a flipping machine bracket 1 and a walking drive motor 3; the flipping machine support includes a cross beam 35 and a vertical beam 36, the cross beam and the vertical beam are connected by bolts, and a series of The connecting rods make the turning machine bracket 1 stable and have a large bearing capacity; the two groups of walking rollers 9 arranged in front and rear on both sides of the turning machine bracket 1 are arranged on the track 33 on the support structure 10, and the walking rollers 9 support On the track, the support is driven to move back and forth along the track, and the turning machine support 1 is erected above the construction was...

Embodiment 2

[0060] The main steps of the decomposition method of the decomposition system of the high-water content construction slag include:

[0061] S1. Construction muck paving. After the construction muck is transported to the disposal site, the muck truck reverses and unloads the soil within the range of the trough along the traveling direction of the dumper and the disintegration system. , so that the height of its loose paving does not exceed 0.8m. During this process, the turner and disintegration system should be moved away from the direction of unloading.

[0062] S2, the ratio of powder curing material. According to the leveled construction muck height and groove width, calculate the square quantity of construction muck per unit area, and determine the surface powder of construction muck per unit area according to the percentage of the powder solidified material in this type of construction muck. The amount of solidified material applied.

[0063] S3. Powder solidifying ma...

Embodiment 3

[0068] This embodiment relies on the future city science center project in Fenghua District, Ningbo, which is a comprehensive urban public service project integrating planning and exhibition, academic research, cultural exchange, educational practice, business leisure and other functions, covering an area of ​​56,777 square meters. The building area is about 19,000 square meters. Excavation of large-scale foundation pits in the project will generate a large amount of engineering slag. According to the previous sampling and test results, the slag in the site is mainly soft soil with a moisture content of more than 40%. Therefore, the decomposition test was carried out by taking the construction waste of this project as an example. Proceed as follows:

[0069] (1) Paving construction waste. Two trucks of construction waste used for the test, about 40m 3 , After the construction waste is transported to the disposal test site, the soil is unloaded and stacked into a stack, and ...

Abstract

The invention relates to a decomposition system for high-water-content construction dregs, which includes a turning machine host, a turning device, an automatic material spreading system, a dust collection system, a spray system and a control system; the turning machine host includes a turning machine bracket and a walking drive motor; the turning and throwing device includes a transmission mechanism at the bottom of the turning and throwing machine support and a turning and throwing shaft in the horizontal direction; the automatic spreading system includes a storage hopper, a servo motor, a vibrator, a buffer spring, and a material guide plate , rotating roller shaft, material guide hole, material guide trough, upper drive wheel, lower drive wheel and drive belt; the dust suction system includes a dust suction system host, a dust suction head and a return pipe; the spray system includes a water tank, Spray booms, nozzles and booms. The beneficial effects of the present invention are: the present invention utilizes the turning and throwing machine and the decomposition system to decompose the construction dregs with high water content and high viscosity, can realize the industrialization of construction dregs treatment, is less affected by the weather, has high work efficiency, and reduces labor costs. labor intensity.

Description

technical field [0001] The invention relates to a decomposition treatment method in the process of resource utilization of construction slag, in particular to a decomposition system and a decomposition method of high-water content construction slag. Background technique [0002] With the rapid development of my country's national economy and the acceleration of urban construction, a large amount of construction waste is generated in the construction of the project. These construction wastes mainly come from the earthwork, waste residue and mud of the construction site, and their disposal methods are mainly on-site consumption. Or dumping overseas, etc. At present, most of the construction wastes are piled up or buried in the site disposal method not only occupying a lot of land, but also causing great pollution to the surrounding environment, and due to the relationship between the road distance and the waste disposal, the government needs to pay The prescribed fee, the phen...
