Problems solved by technology

[0004] 1. The sludge strength in the sludge temporary storage area is extremely low, and the construction equipment is prone to subsidence, making it impossible to directly enter the site for construction
[0005] 2. The temporary sludge storage area was originally covered with high-strength HDPE film. During the construction process, devices such as injection, stirring, and inserting boards will destroy this covering film, and the safety is threatened.
[0006] 3. The reactions between several agents and between agents and sludge do not happen at the same time, but in chronological order, otherwise the treatment effect will not be achieved
[0007] 4. In the process of adding chemicals, the odor will overflow after the cover film is damaged, which may not only endanger the lives of the staff, but also cause pollution to the surrounding environment, which is not allowed in terms of environmental protection
[0008] The implementation of the chemical vacuum preloading method and the dissolved gas-pharmaceutical vacuum preloading method encountered the above four problems in the process of sludge in-situ treatment. If these problems cannot be solved, the chemical vacuum preloading method and the dissolved gas chemical vacuum preloading method it is difficult to implement

Embodiment 1

[0029] In this example, see Figure 1-Figure 3, an intelligent dosing system for sludge in-situ treatment, and also includes a main frame 11, including a walking subsystem, a positioning subsystem, a stirring subsystem and a dosing subsystem; the walking subsystem includes the main frame 11, suspension 19, Rubber crawler 1, polyurethane suction cups 2 and walking control system 12, the rubber crawler 1 and the main frame 11 are connected by suspension 19, and a series of polyurethane suction cups 2 are arranged on the rubber surface of the rubber crawler 1 facing away from the crawler wheels. When the subsystem is walking or the stirring subsystem is in the process of drilling, the polyurethane suction cup 2 and the sludge covering film are tightly sucked, or the polyurethane suction cup is tightly suctioned with the construction cushion, so that the polyurethane suction cup forms a temporary anti-skid and positioning device; A walking control system 12 is installed on the mai...

Embodiment 2

[0041] This embodiment is basically the same as the first embodiment, and the special features are:

[0042] In this embodiment, the intelligent control system controls the medicament adding subsystem to add up to three different medicaments, and by controlling the medicament grouting pump 21 , the interval and duration of addition of different medicaments are regulated. The drill pipe 6 and the triple injection pipe 9 can consider the mutual influence between the chemical reactions of the chemicals. According to the sequence of chemical reactions, different types of chemicals can be injected, and up to three different chemicals can be added. These chemicals react quickly in the sludge. To destroy the microstructure of the sludge, if two or one chemicals need to be added, there is no need to replace the drill pipe. Direct activation of the inner layer and the middle layer can realize the injection of two types of chemicals, and single use of the inner pipe can realize the injec...

Abstract

The invention discloses an intelligent dosing system for sludge in-situ treatment, which includes a walking subsystem, a positioning subsystem, a stirring subsystem and a dosing subsystem, and has four functions of remote intelligent control of positioning, walking, dosing and stirring. Function; the mixing drill pipe and the drug injection pipe are two-in-one, which can realize the injection and drilling at the same time, and the crawler made of light rubber material is used to travel, and all operations can be controlled remotely; Shaft stirring has both drilling and stirring functions. Each shaft is provided with three injection pipes, and each injection pipe is connected to a different chemical grouting pump. On the basis of the existing construction equipment, improve the construction equipment, so that the construction equipment can directly enter the site for sludge treatment, improve the treatment effect, ensure the life safety of the staff, and reduce the pollution to the surrounding environment. The preloading method can be truly implemented, has a high degree of intelligence, is easy to implement and control, and is of great significance to environmental protection.

Description

technical field [0001] The invention relates to a mud treatment device, in particular to a chemical addition system for treating sludge in a sludge pit, which is applied to the technical fields of geotechnical engineering and resource environmental protection. Background technique [0002] Engineering waste slurry, referred to as "waste slurry". As more and more waste mud is produced during the construction of the project, the waste mud will cause serious pollution to the place where it is placed. As people's awareness of environmental protection gradually increases, this extensive mud disposal method is constantly being questioned and opposed, and it is urgent for technicians in the industry to develop efficient and environmentally friendly mud disposal technologies. [0003] The patent document with the patent number of ZL201510322445.6 discloses a chemical vacuum pre-pressing method for treating engineering waste mud, and the patent document with the patent number of ZL2...
