Cloth bag grouting pile-forming method

The invention relates to a method to construct the pile by injecting grout through a bag, which is characterized in that the method comprises the procedures: 1) a pile hole is formed in the soil with a hole-making machine; 2) a bag is sleeved outside a grout injection tube and the bag is bound on the grout injection tube with a strip segment by segment along the axial direction, the two ends of the bag is tightly bundled, the lower end of the grout injection tube is sealed and the grout injection tube is provided with an injection hole on the tube wall; 3) the grout injection tube which is sleeved with the bag is placed into the pile hole; 4) the grout injection tube is used for injecting grout into the bag section by section from the bottom to the top, the next section is injected until the design pressure of the present section is reached until the whole bag is filled with grout and a whole pile body is formed. The invention adopts the bag pile to enhance the soft underlying soil, which ...

Method for preventing pipe blocking of waste rock pumping and filling system

The invention discloses a method for preventing a pumping waste rock filling system from being jammed. The invention is mainly characterized in that an iron removal device is arranged at a waste rock discharge belt; the grate structure of the crusher is changed into a snaillike structure; and the working pressure of the hydraulic system, all the parameters of the pipelines and the slump of the waste rock slurries are controlled. Due to the above measures, the invention guarantees the smoothness during the conveying of the waste rocks such that the filling operation can be carried out smoothly.

Pesticide scavenger composition and use method thereof

The invention discloses a pesticide scavenger composition and a use method thereof. The pesticide scavenger composition can scavenge organic phosphorus and pyrethroid pesticides, and consists of 8-19 percent by weight of wood vinegar and 81-92 percent by weight of sodium chloride. Scavenging solution is prepared by the components according to the ratio of 0.5g:2000mL; and vegetables, Chinese medicine herbs, fruit, tea or tobacco is soaked in the solution for at least 20 minutes and then washed with clear water. The pesticide scavenger has the advantages of convenient use, low cost and good removal effect.

INTELLECTUAL COMPOSITE CHESS

This invention relates to intelligent group board game. The piece (in a board game) is marked with Arabic numerals from 1 to 118, in which 60 pieces are basic piece, the others as additional piece. The intersection chart on chessboard is configurated with more than two group parallel lines forming various geometric nets (square, regular triangle, circle). Some nets with identical figure is made up chessboard which configuration may be square, polygon or other shapes. One set of pieces can play all chessboards which are made up using said figures. It is simple and easy to learn, can be played by persons of different ages.

Pearl syrup and preparation method

Pearl solution features that 100% soluble pearl powder is added in super-pure water and ozone disinfection is used, so it shows transparent, deposition-free and no impurities.

Method for directly utilizing downhole gangue

The invention discloses a method for directly utilizing underground waste rocks. A waste rock pumping and treatment system is established under mine, and the underground waste rocks are directly crushed in the field, are conveyed to a stirring machine by a conveyor, are stirred evenly into a slurry state by adding water in the stirring machine, then are unloaded to a waste rock conveying pump, and are directly filled into a mined-out area through a conveying pipe. The method directly backfills the waste rocks to the mined-out area under mine, solves the reutilization problem of the underground waste rocks, and avoids a series of problems caused by long-term stacking after the waste rocks are conveyed to the ground. The method is adopted to treat the waste rocks under mine and fill the mined-out area, which can effectively reduce the settlement of a crest slab.
