Problems solved by technology

Although the method of adding a curing agent can shorten the curing time, the economic cost of the curing agent is high, and some chemical components will pollute the land environment; in addition, the uniform mixing of the curing agent into the dredging sludge requires special mixing equipment and high personnel and technical requirements. At present, such equipment and technology can only meet the needs of small-scale mixing and stirring, and cannot fundamentally meet the needs of large-scale and large-scale reinforcement of dredging fill, which affects the effectiveness of this type of reinforcement method. Large-scale promotion and application

Abstract

The invention relates to hydraulic fill curing agent mixing equipment, which is installed and connected at a position close to the outlet of the end section of a hydraulic fill delivery pipe. The hydraulic fill curing agent mixing equipment is characterized in that the main body of the hydraulic fill curing agent mixing equipment is a section of rifle delivery pipe. The size of the rifle delivery pipe is consistent with the size of the dredged sludge delivery pipe. The rifle delivery pipe is connected in the hydraulic fill delivery pipe. The middle part of the hydraulic fill curing agent mixing equipment is connected with a curing agent chamber through a curing agent delivery pipe. The other end of the curing agent delivery pipe is connected with the rifle delivery pipe from the side surface. By using a rifle technology, hydraulic fill is enabled to rotate and form a mixed flow, curing agent is automatically sucked in through the delivery pipe by using negative pressure formed close to a pipe wall due to the rotation of a water flow and then the curing agent is fully mixed with the fill. An equipment guarantee is provided for the large-scale engineering application of the curing agent. The problem in large-scale hydraulic filling and reclamation is solved.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering soft foundation treatment, silt solidification, etc., and specifically relates to a new type of conveying and mixing equipment for mixing a curing agent into dredging mud, changing the traditional need to add a curing agent before or after blowing The technology can uniformly mix the curing agent into the dredging sludge while the dredging pipeline is transporting the dredging sludge, so as to achieve the purpose of adding the curing agent and stirring while the dredging and land reclamation, and solve the problem of low output of the traditional process , uneven mixing, long time-consuming, high cost, etc., make the process of dredging filling and solidification treatment be carried out at the same time, which has changed the current situation that it is impossible to solidify a large area of ​​ultra-weak dredger fill. Background technique [0002] With the rapid development of society and...
