Embodiment 1

[0031] Embodiment 1, Figure 1 to Figure 5 Combined with a construction method of slope runoff field, the following steps are carried out in sequence:

[0032] 1) The upper water blocking wall 1 and the lower water blocking wall 5 are respectively arranged parallel to each other along the trend of the slope from top to bottom, that is, the upper water blocking wall 1 is located at a relatively high place, and the lower water blocking wall 5 is located at a relatively low terrain; the left water blocking wall 2 and the right water blocking wall 3 that are parallel to each other are clamped vertically between the upper water blocking wall 1 and the lower side water blocking wall 5; the upper side water blocking wall The water wall 1, the lower water blocking wall 5, the left water blocking wall 2 and the right water blocking wall 3 form a square frame.

[0033] The upper water blocking wall 1, the lower water blocking wall 5, the left water blocking wall 2 and the right water b...

Abstract

The invention discloses a construction method of a sloping surface runoff field, which comprises the following steps of: 1) arranging mutually parallel upper and lower water stopping walls (1) and (5) along the slope trend from the upper side to the lower side respectively, and clamping a left water stopping wall (2) and a right water stopping wall (3) mutually parallel between the upper water stopping wall (1) and the lower water stopping wall (5) to form a parallelogram frame; 2) arranging a left water stopping soil block (21) and a right stopping soil block in the parallelogram frame; 3) embedding a runoff collection tube (4) in the parallelogram frame, wherein fluid flowing along the sloping surface in the parallelogram frame can flow into the runoff collection tube (4) from a bar gap(41); and 4) communicating the runoff collection tube (4) with a runoff collection well (7) by using a water pipe (6). The sloping surface runoff field constructed by the method can fully collect runoff in the sloping surface runoff field.

Description

technical field [0001] The invention relates to a method for constructing a slope runoff field, and the established slope runoff field is used for monitoring the water and soil loss condition of the slope. Background technique [0002] Zhejiang Province is located on the southeast coast of my country, with a land area of ​​102,000 km 2 , the landform types in the territory are complex and diverse, mountains and hills account for 70.4%, plains and basins account for 23.2%, rivers and lakes account for 6.4%, and the cultivated land area is only 2.083 million hm 2 , known as "seven mountains, one water and two fields". Due to its unique natural conditions such as geology, landform, climate, vegetation and soil, as well as the irrational development and utilization of natural resources, the loss of water and soil resources has been serious for a long time. According to the remote sensing survey of water and soil loss in Zhejiang Province in 2004, the total area of ​​water and ...
