Embodiment Construction

[0010] With reference to the accompanying drawings, the structure of the straw drainage body is as follows: a straw section 2 is arranged in a non-woven bag 1, and binding straps 3 are arranged at both ends of the non-woven bag to make the non-woven bag solid. Said straw section 2 is 30-50mm. The specific method of the above-mentioned straw drainage body is: a、 Cut the cotton stalks into straw section 2, the section length is: 30-50mm; b. Soak in antiseptic solution for 3-10 days, remove and wait for solidification to dry; c. Put straw section 2 into non-woven bag 1 Medium, compacted to a certain degree of compactness, use Density Control porosity, thereby controlling water permeability. Non-woven fabrics are selected according to the requirements of water permeability thickness . The length of the non-woven bag is customized according to the construction requirements.

[0011] When constructing the drainage ditch, the specific method is: in the excavated drainage ditch...

Abstract

The invention relates to a straw drainage piece. The straw drainage piece is characterized in that a straw section (2) is placed in a non-woven fabric bag (1), strapping tapes (3) are disposed at two ends of the non-woven fabric bag and tightly tie the non-woven fabric bag (1), and the length of the straw section (2) ranges from 30mm to 50mm. A method for manufacturing the straw drainage piece include a, cutting cotton straws to form the straw section (2) with the length ranging from 30mm to 50mm; b, soaking the straw section in preservative liquid for 3 to 10 days, then fishing out the straw section and solidifying and drying the straw section; and c, loading the straw section (2) into the non-woven fabric bag (1), and compacting the non-woven fabric bag (1) loaded with the straw section (2). The straw drainage piece is cheap in price, rich in material and simple in implementation, is free of environmental pollution, and cannot cause blockage easily.

Description

technical field [0001] The invention belongs to the technical field of drainage bodies and manufacturing methods. In farmland water conservancy projects, groundwater is drained and groundwater is lowered in areas with high groundwater levels and high salinity, so as to achieve the purpose of alkali drainage. Background technique [0002] In areas with high salinity in groundwater and high groundwater level, in order to achieve stable and high yield of crops, it is necessary to drain the groundwater to reduce the groundwater level and achieve the purpose of salt drainage. In order to achieve this purpose, in the past, open trenches were usually excavated at a certain distance. With the development of drainage pipe materials and manufacturing technology and the improvement of construction technology, buried pipes are generally used to reduce the groundwater level at present. Pipe materials generally include ceramic pipes, concrete pipes, plastic pipes, etc. Some materials su...
