JPH0463516A - Method of construction for blocking water penetrating into vinyl house - Google Patents

Abstract

PURPOSE:To provide the title method of construction so designed that a gutter is dug on the framework side of the soil in a vinyl house and a water-blocking film is suspended along the vertical inner surface on the framework side followed by refilling the gutter, thereby effectively preventing the development of an excess of water due to excess penetrating water from the outside of the vinyl house even in the heavily rainy season. CONSTITUTION:A gutter 3 e.g. 30-100cm wide and 30-100cm deep is dug over the entire length of a vinyl house 1 on the framework side of the soil in said vinyl house 1, and a water-blocking film 4 ( e.g. a sheet having water-blocking ability) is suspended along the vertical inner surface on the framework side and, where needed, a drain pipe 5 is provided at the bottom of the gutter 3. Thence, the gutter 3 is filled with a water-absorptive material 6 (e.g. straw) and refilled with soil.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for preventing soil in a greenhouse from becoming overly moist due to excessive seepage water.

Prior Art and Problems As shown in Figure 3, no means is provided to block excess water from seeping into the soil 2° within the greenhouse 1.

Therefore, during the heavy rainy season or long rainy season, the plastic greenhouse 1
2° of soil within the area has become overly moist due to excessive infiltration of water from the outside, resulting in uneven crop growth.

That is, the phenomenon of excessive moisture in the soil 2' occurs over almost the entire length of the house frame side parts (approximately 1 to 2 meters wide) on both sides of the greenhouse 1', and when the phenomenon of excessive moisture occurs, root rot etc. Planting is severely inhibiting crop growth. Therefore, when it comes to planting crops, the plants grow poorly in the greenhouse frame side areas (about 1 to 2 m wide) on both sides of greenhouse 1', where excessive moisture is observed, and in greenhouse 1', where excessive moisture is not observed. Around the center, growth is standard and there are differences in growth.

The present invention has been developed by focusing on this problem, and is designed to prevent the soil inside the greenhouse from becoming over-hydrated even during heavy rainy or long rainy seasons. The purpose is to propose water isolation methods.

Means for Solving the Problems The means achieved by the present invention to achieve the stated purpose is to dig a gutter in the soil inside the greenhouse on the side of the house frame;
After installing a water-blocking membrane vertically on the inner surface of the house frame side line of the gutter, the gutter is backfilled.

Example This will be explained with reference to the drawings.

Side ditches 3 are dug in the soil 2 within the greenhouse 1, and the ditch excavation areas are biased towards the house frame side on both sides (see the imaginary lines in Figure 1).

The means for excavating the side ditch 3 is determined by taking into account the area inside the greenhouse 1, the soil quality, and the dimensions of the side ditch 3, whether it is mechanical digging using a small civil engineering machine or manual digging using human power.

Gutters 3 should be dug along the entire length of the greenhouse 1, or
Width dimensions, depth dimensions, etc. are based on the area within greenhouse 1,
It is determined depending on the soil quality, the annual rainfall amount and annual rainfall distribution of the area where the greenhouse is constructed, and, for example, the width and depth dimensions are determined to be between 30 and 100,011. The cross-sectional shape of the side gutter 3 may be a ■-shape (illustrated example), a U-shape (not shown), or the like.

The water-blocking membrane 4 is separate from the house vinyl used in the construction of the greenhouse 1, and may be a soft synthetic resin membrane of the same quality as the vinyl, or a soft synthetic resin membrane of a different quality. In addition, it may be a fabric that has been subjected to waterproof treatment, and in short, any sheet or thick or thin film that has water-blocking ability may be used. The water-shielding membrane 4 is brought into vertical contact with the inner surface of the house frame side line of the gutter 3 (in other words, the inner surface of the embroidered penetrating water), and the upper part is placed in contact with the soil 2.
It is exposed upward and attached to the house frame and/or house vinyl by appropriate means (for example, pasting, welding, hook and button, fastener, binding, and other attachment means), and the hanging state is maintained. This is done so that the seepage water does not excessively permeate into the soil 2 in the greenhouse 1.

After digging side ditches 3 in the soil 2 inside the greenhouse 1 and installing the water-blocking membrane 4 vertically, the side ditches 3 are backfilled and made flat, making it possible to plant crops (see Figure 1). ).

The soil 2 inside the plastic greenhouse 1 has a water-blocking membrane 4 buried along the entire length of both sides of the greenhouse, so that excessive seepage water is blocked, preventing excess water content, and preventing the soil 2 from becoming too moist on the side of the house frame. Once the crops are planted, they can be expected to grow normally, just like the crops around the center of the greenhouse (see the same diagram).

Depending on the soil quality of the soil 2 in the greenhouse 1, the gutter 3
There are cases where backfilling is performed without configuring drainage equipment for removing seepage water, and cases where backfilling is performed with configuring such equipment, so this drainage equipment will be referred to here.

Basically, it is possible to configure the above drainage equipment as shown in the first diagram, but if the soil type is soil 2 or clay, it is possible to construct the drainage equipment as shown in the second diagram. A drain pipe 5 is installed at the bottom of the gutter 3, and then filled with a water-absorbing material 6 having water-absorbing and water-retaining properties such as raw sugar or rice straw, and then the gutter 3 is backfilled. In addition to the water-blocking function, the seepage water removal function of clayey soils with poor water-absorbing properties is improved, and even if seepage water seeps from below the water-blocking membrane 4,
Water is absorbed by the water absorbing material 6 and drained from the drain pipe 5. The drain pipe 5 used in this example has many drainage holes (not shown) in the pipe wall.
The drain pipe 5 may have a porous structure with open holes or a normal non-porous structure having no drainage holes, but if it has a porous structure, water can be sucked and drained from any part of the drain pipe 5. Although it is possible to arrange several drain pipes 5 in the length direction of the side gutter 3 with their ends touching each other, in the case of a non-porous structure, the ends of the drain pipes 5 can be extended to drain water and water. Therefore, it is necessary to arrange several drainage pipes 5 along the length of the side gutter 3 with their ends spaced apart from each other.

Effects of the Invention The present invention digs a side ditch in the part of the soil inside the greenhouse on the side of the house frame, as shown above, and installs a water-blocking membrane on the inner surface of the side line of the house frame of the side ditch, and then backfills the side ditch. It becomes possible to block excess water from penetrating with a water-blocking membrane. Therefore, even during heavy rainy or long rainy seasons, excess moisture can be prevented on both sides of the soil inside the greenhouse, and if crops are planted in the gutter backfilling area, they will grow in the same way as crops in the center of the greenhouse. Standard growth is allowed, and differences in crop growth can be prevented.
