Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse agricultural drainage ditch, in particular to a novel greenhouse agricultural drainage ditch. Background Art

[0002] Greenhouse agricultural drainage ditch is a drainage facility used to prevent crop losses in greenhouse agriculture due to floods. The purpose of this drainage ditch is to quickly discharge the rainwater and irrigation water accumulated inside the greenhouse to avoid the roots of crops being soaked in water, resulting in death or reduced production. The drainage ditch facilities in modern greenhouse agriculture are mainly traditional earth ditches, concrete drainage ditches, prefabricated drainage ditches (concrete type) and prefabricated drainage ditches (plastic type). The drainage ditch facilities in modern greenhouse agriculture still have the following problems:

[0003] 1. Traditional earthen canals: Weeds are easily grown in the canals, resulting in water flow being blocked and poor drainage effect; the overall strength is low and the durability is poor. In extreme rainy weather, the canal shape is easily damaged by rainwater, leading to canal collapse, etc.

[0004] 2. Concrete drainage channels: The construction cost is high and the difficulty is great. The biggest problem is that once abandoned, the farmland area occupied by the channel is difficult to recultivate, which causes great damage to the farmland environment.

[0005] 3. Prefabricated drainage channel (concrete type): The initial cost is high, and the costs of component production, transportation, and storage need to be considered; the installation accuracy is high, and factors such as component size and reserved holes in the excavated channel need to be considered; the occupied area is relatively large, which may affect the area of ​​arable land; the maintenance is difficult, and special tools and techniques are required to replace damaged components.

[0006] 4. Prefabricated drainage channels (plastic type): high cost, the cost of component production, transportation, and storage must be considered, and in order to ensure the degree of its impact on the environment, green materials are selected, which are more expensive; high installation accuracy, the need to consider factors such as component size and reserved holes in the excavated channel; high maintenance difficulty, special tools and techniques are required to replace damaged components; plastic materials have good water permeability, but low strength, due to factors such as light and high temperature will cause the channel to deform, after deformation, there will be a gap with the surrounding excavated ditches, causing water leakage, and therefore, it is impossible to divert water well into the prefabricated channel.

[0007] Therefore need a kind of novel greenhouse agriculture drainage ditch to solve the above-mentioned problems. Utility Model Content

[0008] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0009] Therefore, one purpose of the utility model is to propose a new type of greenhouse agricultural drainage ditch to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0010] In order to achieve the above-mentioned objectives, an embodiment of the utility model on one hand provides a new type of greenhouse agricultural drainage ditch, including a foundation, an agricultural greenhouse is arranged on the foundation, an external drainage ditch and an internal drainage ditch are opened on the foundation, a first soil hardening layer is arranged inside the external drainage ditch, a first waterproof membrane is arranged inside the first soil hardening layer, a weeding film is arranged above the external drainage ditch, a rainwater conveying pipe is arranged inside the external drainage ditch, a second soil hardening layer is arranged inside the internal drainage ditch, a second waterproof membrane is arranged inside the second soil hardening layer, a moisture-proof membrane is arranged on the top of the internal drainage ditch, and a bending-resistant covering plate is arranged on the top side of the moisture-proof membrane.

[0011] Preferably, in any of the above schemes, the shape of the external drainage ditch is an inverted trapezoid, and the shape of the internal drainage ditch is a rectangle.

[0012] Preferably, any of the above schemes is that the external drainage ditch is located outside the agricultural greenhouse, and the internal drainage ditch is located inside the agricultural greenhouse.

[0013] Preferably, any of the above schemes is that the first soil hardening layer and the second soil hardening layer are both layered structures formed by hardening foundation soil using a soil hardener.

[0014] Preferably, any of the above schemes is that both the first waterproof membrane and the second waterproof membrane have a light-shielding effect, and both the first waterproof membrane and the second waterproof membrane are made of environmentally friendly materials.

[0015] Preferably, any of the above schemes is that the first soil hardening layer, the first waterproof membrane and the weed control membrane are installed on the foundation by fixing nails.

[0016] Preferably, any of the above schemes is that the rainwater conveying pipeline is connected to the rainwater conveying pipeline collected on the roof of the agricultural greenhouse.

[0017] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0018] 1. In terms of channel material selection, this new type of greenhouse agricultural drainage ditch abandons the concrete hardened canals that are easily blocked by silt and difficult to recultivate, and the prefabricated canals that are prone to deformation and have high construction costs. At the same time, it also abandons the traditional simplest earth ditches. Instead, after digging the external drainage ditch, the soil is reinforced with soil hardener, and then the first waterproof membrane is laid in the external drainage ditch to prevent a large amount of rainwater from penetrating into the interior of the agricultural greenhouse through the bottom of the soil in extreme weather. A weed control film is covered on the top of the external drainage ditch, and a moisture-proof film and a bending-resistant covering plate are covered on the top of the internal drainage ditch to facilitate people walking on the ditch.

It is easy to recultivate after abandonment and has less damage to the environment. It also effectively improves the flood resistance of agricultural greenhouses and the service life of steel structures of agricultural greenhouses.

[0019] 2. Through the overall design concept of setting up external drainage ditches and internal drainage ditches in agricultural greenhouses, relevant materials such as soil solidifiers, weed control films, waterproof films, etc. can be cleverly utilized, which not only solves the difficulties of fixing the pool shape and facilitating recultivation, but also ensures that while meeting the durability requirements, the materials are low-priced and green and environmentally friendly, reducing the cost of building this new type of greenhouse agricultural drainage ditch and facilitating later maintenance operations.
