Description

A mixing device of material for water cut-off}

The present invention relates to a process and apparatus for mixing earth and sand materials, which are the raw materials for the order, for the construction of a water repellent layer on the bottom and the slope of a landfill in the construction process of a new landfill, The present invention relates to an apparatus for mixing raw materials for mixing raw soil soil (granite soil) and ordered materials (solid additives) such as a raw material feeder and a meter, and mixing them effectively using an agitator and a screw paddle mixer.

In general, in order to prevent leachate from leaking to construction sites such as dams, reservoirs, and drainage sites, as well as waste landfills, the order layer is constructed. At this time, the order layer is constructed of clay with a low permeability coefficient. Due to this difficulty, raw earth soil (granite soil), which is widely distributed in Korea among mixed order materials, is selected and used as the main material.

However, raw earth soil (granite soil) is generally inadequate in its own application, and is used to make a mixed material in which lime, cement, fly ash, bentonite, etc. are added to the raw earth soil.

As described above, in order to produce a mixed soil used in the order layer, a raw material is generally mixed by using a fork crane equipped with a bucket stabilizer in a back hoe, or in some cases, a raw material is passed through a vibrating body or a cylindrical mixer. The mixing method is mainly used.

In the conventional method of mixing raw materials for ordering materials, the ordering materials are not fixed and the mixing ratio is not constant, and most of them are neglected, which is the biggest factor of subconstruction work. Since the ordering material mixture is installed in the ordering layer, cracking occurs due to an unbalanced blending of the ordering material even if the compacting work of the ordering layer is firm, resulting in a problem of lowering the ordering ability.

In other words, the conventional mixing method of the raw materials for the order is that the mixing ratio of the ordering material is not consistently adjusted by depending on the loading capacity of the vehicle or the eye weight, and the ordering materials of different materials are mixed by mixing the ordering materials using the fork lane. It is not mixed enough.

The present invention is designed to solve the problems caused by the conventional mixing method of the raw materials for ordering, to select the particle size of the raw soil soil used as a composite raw material when constructing the order layer with a sorter, and to select the selected soil soil and various kinds of order material Stored in the feeder, the raw earth soil and the ordered material stored in the feeder is transferred to the meter and weighed at a constant blending ratio, and the metered raw soil soil and the ordered material are fed to the stirrer and the first mixing process is performed, and mixed by the stirrer. It is an object of the present invention to mix the raw materials for the order uniformly enough to be suitable for construction by making the secondary raw materials to be secondly mixed more effectively while being transferred to the screw paddle mixer.

The present invention consistently measures the raw material for the order in accordance with the mixing ratio in the meter and evenly mixes the order for the metered material in the stirrer while performing a mixing process while spraying a certain amount of water in the screw paddle mixer to improve the ordering ability It is to produce raw materials for ordering.
