Embodiment Construction
[0020] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 with figure 2 As shown, the on-site dredging pipeline mixing device for solidifying agent and dredging mud provided by the present invention is a tubular structure, comprising an outer pipe 1, and the injection nozzles arranged sequentially from the inlet at one end to the other end of the outer pipe 1. Type liquid-liquid mixer 2 and static mixer 3 two stages. The jet liquid-liquid mixer 2 and the static mixer 3 are combined. Increase the uniformity of mixing dredging mud and curing agent to ensure uniform settlement of foundation soil.
[0022] The entrance of the outer pipe 1 is provided with a clamp, a flange, and matching screws and nuts that can be fixed to the dredging mud pipeline connected thereto.
[0023] The jet liquid-liquid mixer 2 includes a curing agent inlet 21 arranged on the side wall of the out...

The invention discloses a field dredger-fill pipeline mixing device of a curing agent and dredged spoil. The field dredger-fill pipeline mixing device is of a pipe-shaped structure and comprises an outer pipe as well as a jet-type liquid-liquid mixer and a static mixer which are arranged inside the outer pipe from an inlet in one end to the other end of the outer pipe. The jet-type liquid-liquid mixer comprises a curing agent inlet which is formed in the side wall of the outer pipe as well as a jet nozzle section, a receiving chamber, a mixing chamber and a diffuser which are sequentially arranged inside the outer pipe. The curing agent inlet is formed in the side wall of the outer pipe at the outer side of the jet nozzle section, and the curing agent inlet is communicated with a space formed by the side wall of the outer pipe and the outer wall of the jet nozzle section; the inside of the static mixer is of a cylindrical structure, and a continuous spiral baffle plate is arranged inside the static mixer to form a spiral rifling structure. By adopting the field dredger-fill pipeline mixing device of the curing agent and the dredged spoil, purposes of adequately mixing and rapidly curing the dredger spoil and the curing agent and shortening the treatment time can be achieved.
Description
technical field [0001] The invention relates to a mixing device for a curing agent and dredging mud, in particular to a mixing device for a curing agent and dredging mud for on-site dredging and filling pipelines. Background technique [0002] With the rapid development of the marine industry, land reclamation projects continue to expand, and advanced reclamation technology is required to meet large-scale foundation reclamation projects. Using dredged mud as a filling material can not only solve the problem of the source of a large amount of soil materials required for filling, but also solve the problem of a large amount of dredged mud occupying land due to the development and maintenance of ports and waterways and the serious pollution of the marine environment. ecological problem. It has been found in practice that the dredged mud has high water content and low bearing capacity, which brings about subsequent foundation retreatment problems. [0003] Most of the existing...
