The bottom side of the shell in FIG. 6 is in a V-shaped triangular waveform; the wave length is equal to the housing width. The cross-sectional shape of the marine barrier is determined by the paving machine bottom waveform. The control system comprises a horizontal state detector arranged on each paving machine, and provides a real-time horizontal state for a control system host. The content of the detector and control can be referred to in the art;

This is the default placement and export mode of the marine barrier; one side of the waterproof material is a reinforced edge 19, and the waterproof material is conveniently inserted into a gap between the upper roller and the lower roller of the closer by a hand during installation and pushed along the gap.
One housing contains more than one closure 11, which has two stable states, an open state and a closed state: when the closer is in an open state, the gap between the upper roller and the lower roller is enlarged, so that the water-proof material is convenient to be filled; when the closer is in a closed state, the gap between the upper roller and the lower roller is reduced to block the entry of soil.

A water-proof area 27 is built in a water-deficient area, and comprises an urban area 28 and suburban farmlands around the urban area, water-proof materials are paved under the suburban farmlands to form the water-proof farmlands, and each air rain-increasing operation area shown by a dotted line graph is designed each time. The area, shape, position and height of the rain-increasing operation area are changed according to the field conditions including wind direction change.
The embodiment 2 has the beneficial effects that: the construction of the water-proof area superposition rain-increasing technology can independently increase the rain of the water-proof farmland to improve the soil moisture content, can independently bring rainwater to urban roads, buildings and greening, freshens air, and can obtain water through a rainwater collecting system.
