The SPL-6 wet shotcrete machine uses wet mix, which has the characteristics of small working dust, high spray layer strength, large disposable spray thickness, low rebound rate and small injection pulse, which greatly improves the underground working environment. Improve construction quality and work efficiency and construction level of anchor spray support.
The construction process of SPL-6 wet shotcrete machine has the following characteristics:
(1) Concrete mix can be incorporated into the design water, which is beneficial to the hydration of the cement in advance, so the concrete strength is higher.
(2) The proportion of the mixture can be controlled more accurately.
(3) Accelerators generally cannot be added in advance, and should be added after the mixture flows into the jet.
(4) The amount of dust and rebound is low, and the production environment is in good condition.
(5) Wet shotcrete machine equipment is more complicated, and special technical training is required for use and maintenance.
(6) The distance and height of the feeding are much smaller than the dry spraying method. The arrangement of the injection system should be close to the working surface. Try not to place it on the inclined roadway, and the placement should be firm and reliable.
