Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new method for constructing so-called furrow roads, which are provided at boundaries between agricultural lands, etc., and the furrow roads constructed by this method.

Aze-do not only indicates the boundaries mentioned above, but also serves as a simple road,
It is normal for it to play the role of a waterproof embankment, and it is often seen as a necessary condition.

However, in reality, furrows are nothing more than embankment-like accumulations of old rice, earth and sand, gravel, etc., which can cause boundary disputes, and are not sufficiently waterproof, allowing water to flow in and out, causing water conflicts. The furrows, which often become a habitat for weeds and pests and have a negative impact on chinese crops, are hardened using a hardening agent such as cement to prevent water from penetrating and prevent weeds and pests from inhabiting them. It has been desired to develop a special hardening agent that would make it impossible or difficult to use, and also make it convenient as a simple road.The present invention overcomes the above-mentioned problems, A method for constructing a furrow in which a fast-hardening agent is mixed, the furrow is first quickly formed into a predetermined shape by the fast-hardening component, and the furrow is further hardened by a cement component, and this method The purpose is to provide a footpath created by

It has already been mentioned that the hardening agent used in the construction method of the present invention includes a fast-setting component and a cement component that has hardening power as a cement. (including partially dehydrated products thereof), calcium aluminate, calcium sulfate, etc., and it is desirable to further add sodium carbonate to buffer and adjust the pH.

Specifically speaking, the quick hardening component is aluminum sulfate anhydride 2
0 to 60% (based on weight, the same applies hereinafter), calcium oxide or Fi/and calcium hydroxide (calcium oxide subtraction) 5' to 30%, sodium carbonate θ to 10%, alumina carbonate 5' to 75% Furthermore, if 200% or less of the total amount of hemihydrate gypsum or alumina cement, which quickly develops strength, is added to this, good dispersion can be achieved. Cement ingredients include regular Portland cement, blast furnace cement made by adding granulated blast furnace slag powder, silica cement, fly ash cement, iron cement, jet cement, colloid cement, alumina cement, high sulfate slag cement, etc. can be used depending on the characteristics of each. Incidentally, whether gypsum hemihydrate, alumina cement, etc. are included in the quick-hardening component or in the cement component, the result is the same.

An example of the embodiment of the present invention is as follows.

As a quick hardening component, aluminum sulfate 10% quicklime 20%
%, a mixture of 10% Ng ash and 60% alumina cement, cement components: 60 parts of Portland cement, 30 parts of high-grade slag, gypsum c1sO4・O,
, prepare a mixture of 10s as 5H20, for example, 20 parts of the former, ! 80 copies! -To join together. The curable volume per 25 kLi of this mixture is approximately 0.15 to 0.3 Ba. The most important physical property of the furrow to be treated is moisture content, and it is desirable that it be within the range where it can be squeezed with the hands to form nodules.If no nodules do not form, water should be replenished, and the soil will protrude between the fingers. In some cases, it is necessary to choose the drying period. In the work, the mixture and furrow soil are sufficiently mixed using an appropriate tool such as a cultivator or a hoe. The processing depth is
Approximately 10 c#I is sufficient for walking and weed control, but if you want to prevent water from flowing out or flowing in, it is necessary to make it sufficiently deep, even at the cost of width.

The furrow construction method of the present invention is used for so-called sludge,
It can be cured early and can also be used on earthen walls of houses to achieve early drying and assimilation.

As described above, the method for constructing a footpath of the present invention involves mixing a hardening agent containing a cement component and a quick-hardening component into the soil constituting the footpath while keeping the soil solid enough to maintain nodules. Fluid mt-It hardens in a single hour (several hours to a day) without any preparation, and can maintain its hardness for many years. It is also effective against targets that contain almost no sand.
