Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a soil improvement method.1) Specifically, the invention relates to a method for improving soil, including physical and chemical improvement of soil on golf course greens, paddy fields, and farmland. This is related to.

(Conventional Technique WI) Conventionally, on golf course greens, etc., after construction, the deep soil is compacted due to tread pressure by players or rolling by management equipment, resulting in poor water permeability and poor grass growth. Methods have been implemented to improve this problem by using a surface drilling machine such as Pest Seer, but the effect was lost in a short period of time.

In addition, in dark drainage facilities such as rice paddies and farmland, there are permeable gaps between the soil clods that are backfilled in the dark drainage ditch at the time of construction.]
Although they function well, this soil mass often collapses due to seepage from rainfall, leaving no permeable pores, resulting in a significant reduction in the drainage capacity of the dark soil, which has become a problem.

(Problem to be solved by the invention) Therefore, the applicant of the present application proposed the patent application Sho! T-/9! ; In No. 331, as a means to solve the above conventional problems,
A hollow nozzle with an air outlet near the tip is driven into the soil, and compressed air is ejected from this outlet to create cracks in the soil. be.

However, this method has the disadvantage that once cracks have been created, the entire soil conditioner must be injected again using a pump and hose, which takes time and effort twice, and that the liquid does not penetrate deep into the cracks in the soil. There it was.

Therefore, in order to solve these drawbacks, the present inventor conducted various research on a method of simultaneously causing cracks with compressed air and simultaneously injecting a liquid agent, and as a result arrived at the present invention.0 (Means for solving the problems) That is, the present invention (1) Push a hollow nozzle with an air outlet near the tip into the soil, and a hollow pipe with an integrated outlet so that the hollow/spool has a dual structure.) All of the liquid is ejected from the hollow pipe. This soil improvement method is characterized by blowing out compressed air from a hollow nozzle spout while causing cracks in the soil, and injecting a liquid agent into the cracks to bring them into contact.

The configuration of the present invention will be explained in detail below.

First, to explain the construction machine used in the present invention, the machine body (10) has an engine and a compressor mounted together, and a hollow nozzle (1) and a hollow pipe c2 that eject pressurized air using the power of the SX engine. ) is pushed into the ground.

In addition, the hollow nozzle has a diameter of φ2~Jam and has a large opening that blows out compressed air.
cm.

A ground plate (4Q) is installed on this machine body, and a hollow pipe is attached to the machine body to create a double structure with the hollow nozzle for fully pumping and ejecting the liquid, and a hose is attached to this hollow pipe so that the liquid can be fed under pressure from the pump σ. (6) are connected to complete the construction machine used in the soil improvement method of the present invention.

Next, to explain the construction method, first, the construction machine is brought into the site where the soil is compact, one ground plate is fixed, and the hollow nozzle and hollow pipe are simultaneously connected underground to the ground by the power of the engine.
0 to 1, push it into the Qarn 0) Next, pump a liquid containing diluted soil aggregation agents such as polyamide oxide, liquid fertilizer, and pesticides for pest control from the storage tank to the hose through the pump. 1. A cock (J') attached to a hollow pipe? Squirt out the open liquid. At the same time, a compressor converts 2 liters of air into 0-9 liters in about io seconds.
．． It is ejected from the spout at the tip of the hollow nozzle 4 at a pressure of 5 kg/cm, creating many cracks (η) in the deep soil, injecting the liquid into the cracks and bringing them into contact, and completing the construction by pulling up the hollow nozzle and hollow pipe. do.

(Effects of the Invention) As described above, the present invention provides a hollow nozzle installed in soil with an air outlet near its tip, and a hollow pipe provided with an air outlet integrated with the hollow nozzle to form a double structure. This soil improvement method is characterized by fully pressing the soil, blowing out compressed air from the hollow nozzle outlet while squirting the liquid agent from the hollow pipe to generate cracks in the soil, and injecting the liquid agent into the cracked portion and bringing it into contact with the cracks. Therefore, the deep soil of golf course greens, paddy fields, and farmlands, which there was nothing we could do until now, will be affected by the introduction of the deep soil. 9 Water permeability has been improved, and even in areas where lawn growth has been hindered, the soil remains porous due to the action of the soil aggregation agent, and liquid fertilizer and pest control chemicals are also injected. Because of this, green grass shows good growth.

Furthermore, with the construction method of the present invention, even in the case of dark drainage facilities in paddy fields and farmland, where the soil clods have collapsed due to seepage water and there are no permeable gaps, the drainage capacity of the dark drainage facilities has been significantly reduced. The water permeability of Dark Kiyo has been improved.

Moreover, once the conventional method cracks? It used to take a lot of time to pull it up and then inject the liquid again with a hose, but according to the construction method of the present invention, the work can be completed in one go, and the hollow pipe allows the liquid to be injected deep into the soil, making it completely workable. It has many effects, such as allowing the liquid to penetrate into deep cracks.

Claims (1)

[Claims] A hollow nozzle with an air spout near the tip and a hollow pipe with a spout that is integrated with the hollow nozzle to form a double structure are pushed into the soil, and while the liquid agent is spouted from the hollow pipe, the hollow nozzle is inserted into the soil.
