Description

Technical Field

[0001] This utility model relates to the field of soil water conservation technology, specifically a water conservation device for reclaimed land for housing. Background Technology

[0002] House reclamation land refers to usable land formed after the original houses are demolished, the land is leveled and the soil is improved. Because the soil structure is damaged during the construction of houses, the reclaimed soil generally has problems such as low porosity, poor water and fertilizer retention capacity, and easy water leakage or evaporation, which leads to limited crop growth and the need for frequent irrigation, which not only wastes water resources, but also increases the maintenance cost of reclaimed land.

[0003] Existing water retention technologies mostly employ methods such as laying mulch film and adding water-retaining agents. However, mulch film is prone to aging and damage and is not conducive to soil aeration. Water-retaining agents need to be fully mixed with the soil, which is difficult to implement. Furthermore, long-term use may affect the soil structure. Therefore, it is necessary to design a water retention device for reclaimed land to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please refer to Figure 1-5As shown, this utility model provides a water-retaining device for reclaimed land for houses, including a water-retaining body 1 and a funnel-shaped cover plate 5 for covering the upper end of the water-retaining body 1. The lower side of the side wall of the water-retaining body 1 is provided with a breathable water-retaining hole 2. The inner side of the water-retaining body 1 is provided with a water-retaining filler 3. Through the function of the water-retaining filler 3, water can be quickly absorbed and locked in irrigation water or rainwater. A fixing ring 4 is fixedly connected to the outer side of the upper end of the water-retaining body 1. The upper end of the water-retaining body 1 is provided with a funnel-shaped cover plate 5. Through the function of the funnel-shaped cover plate 5, external impurities can be prevented from entering the interior of the water-retaining body 1. A water-containing body 1 has a water-guiding pipe 6 in the middle. A filter head 7 is fixedly connected to the lower end of the water-guiding pipe 6. The filter head 7 has activated carbon filler 8 inside. The water-guiding pipe 6 can guide water from the deep soil upwards and guide excess surface water into the deep layer to avoid water accumulation in the soil. The filter head 7 and the activated carbon filler 8 can filter soil impurities, prevent the water-guiding pipe 6 from getting clogged, and ensure the water guiding effect.

[0018] Specifically, a waterproof and breathable membrane 9 is provided on the inner side of the air-permeable and water-retaining hole 2. The waterproof and breathable membrane 9 inside the air-permeable and water-retaining hole 2 can reduce water evaporation and prevent water from leaking out too quickly, thereby improving soil moisture utilization and reducing irrigation frequency.

[0019] Specifically, a fixing nail 10 is fixedly connected to the lower end of the fixing ring 4, and a barb 11 is fixedly connected to the outer side of the fixing nail 10. By inserting the fixing nail 10 at the lower end of the fixing ring 4 into the soil, and with the help of the barb 11, the water-retaining body 1 can be effectively fixed to ensure the stability of the equipment.

[0020] Specifically, overflow vent holes 12 are provided at the edge of the bucket-shaped cover plate 5. The overflow vent holes 12 can not only guide irrigation water but also improve soil permeability. Water guide holes 13 are provided in the middle of the bucket-shaped cover plate 5. The water guide holes 13 allow the water guide pipe 6 to pass through the bucket-shaped cover plate 5 and penetrate deep into the soil.

[0021] Specifically, the upper end of the water pipe 6 is sealed and connected to the limiting water guide bucket 14. The lower end face of the limiting water guide bucket 14 is in contact with the upper end face of the bucket-shaped cover plate 5. The limiting water guide bucket 14 can limit the top of the water pipe 6.

[0022] Specifically, the lower end of the side wall of the water pipe 6 is provided with water guiding micropores 15, which can be used to introduce or export surface or deep water.

[0023] Specifically, the water-retaining body 1 is made of biodegradable plastic. The biodegradable plastic material of the water-retaining body 1 will not pollute the soil environment and meets environmental protection requirements.

[0024] Working Principle: This utility model is a water-retention device for reclaimed land used for housing construction. During installation, holes are first drilled in the area of ​​the reclaimed land where water retention is required, allowing the water-retention body 1 to be inserted. The fixing nails 10 at the lower end of the fixing ring 4 are inserted into the soil, and the barbs 11 effectively secure the water-retention body 1, ensuring stability. Then, the water guide pipe 6 passes through the water guide hole 13 in the middle of the funnel-shaped cover plate 5, and the bottom filter head 7 extends into the soil. Finally, the water-retention filler 3 is inserted into the inside of the water-retention body 1, and the top is closed by the funnel-shaped cover plate 5 to prevent impurities from entering. When irrigation is needed on the reclaimed land, water enters the water-retaining filler 3 through the overflow vent 12 at the edge of the funnel-shaped cover 5 and is absorbed and locked in. The waterproof and breathable membrane 9 inside the vent and water-retaining holes 2 can slowly release the water into the surrounding soil, so that the water can be fully utilized and the soil can be breathable. At the same time, the water-guiding micropores 15 on the outside of the water-guiding pipe 6 can guide the deep and surface water in both directions to ensure the soil moisture balance. Furthermore, the filter head 7 and activated carbon filler 8 can filter soil impurities, prevent the water-guiding pipe 6 from being blocked, and ensure the water guiding effect.
