Anti-leakage pulp circulation intelligent pulping and pressing system

Abstract

An anti-slurry-leakage circulating intelligent slurry making and pressing system is provided with a circulating pump, and the inlet end and the outlet end of the circulating pump are communicated with a high-speed stirring slurry making barrel to form a circulating loop of the circulating pump and the high-speed stirring slurry making barrel; a low-speed stirring circulating pipeline communicated with a low-speed stirring slurry storage barrel is arranged in a slurry pressing machine discharging pipeline to form a circulating loop of a slurry pressing machine and the low-speed stirring slurry storage barrel; an automatic slurry and water-binder ratio judging device is arranged on a conveying pipeline at a prestress hole channel slurry outlet communicated with the low-speed stirring slurry storage barrel. The anti-slurry-leakage circulating intelligent slurry making and pressing system has the advantages that automatic weighing, automatic feeding, automatic slurry making, automatic slurry pressing, automatic slurry pressing data storage and automatic pressure and time curve generation of an existing intelligent slurry making and pressing system can be achieved, slurry making efficiency is higher, the slurry making effect is better, damage caused by idling of the slurry pressing machine can be prevented, the phenomena that pipelines are broken and slurry leaks due to too large pressure can be effectively avoided, whether the slurry and water-binder ratio is qualified or not can be automatically judged, slurry which is not qualified is automatically removed, the slurry is prevented from accumulating in the pipelines, and cleaning is convenient.

Description

technical field [0001] The invention relates to the technical field of prestressed engineering construction, in particular to an intelligent slurrying and pressing system for anti-leakage slurry circulation. Background technique [0002] Grouting in the tunnel is one of the most important processes in the post-tensioned prestressed concrete structure. Whether the grouting is full and dense has a decisive impact on the corrosion of prestressed tendons, the loss of prestress, and the stiffness of prestressed components, and directly affects the quality of prestressed concrete. Structural security and durability. The traditional grouting method for prestressed pipelines is controlled by manual operation, which has many disadvantages: (1) manual weighing of ingredients, inaccurate control of water-binder ratio, resulting in serious bleeding; (2) uncontrollable pressure resulting in insufficient grouting; (3) Manually record data, human factors are uncontrollable and easy to fal...

Problems solved by technology

The inventor owns Chinese patent 201320831177.2, which discloses an intelligent pulping and grouting system, which can realize the functions of automatic automatic weighing, automatic feeding, automatic pulping, automatic grouting, automatic recording of grouting data and automatic generation of pressure time curves ; But it has the following disadvantages: 1. High-speed stirring is driven by a single motor, which requires a large motor power and large vibration during work, and sometimes the stirred slurry is not fine enough; 2. Due to the high pressure at the end of grouting, it is easy to appear Slurry leakage; 3. The grouting machine is easy to be damaged due to idling; 4. It is impossible to determine whether the slurry-water-binder ratio of the slurry outlet meets the requirements

[0004] Chinese patent 201210194412.4 discloses a prestressed grouting trolley and a circulating grouting method. The water-binder ratio tester can be used to measure the water-binder ratio, but it has the following defects: due to the water in the prestressed pipeline during the circulating grouting, the dilution The slurry is destroyed and its water-binder ratio is destroyed. These unqualified slurry cannot be eliminated, and are returned to the storage tank through a closed circuit, resulting in damage to the water-binder ratio of the entire bucket of slurry.
