[0022] The technical solutions of the present invention are further described below with reference to the accompanying drawings and specific embodiments.
[0023] Combine now figure 1 , figure 2 , image 3 , Figure 4 As an example to illustrate: first, at the location where the closed wall needs to be constructed, the top plate 1, the bottom plate 3 and the two roadway walls 7 are cut out, and then a wooden wall 2 is built behind the construction roadway, covered with plastic film, and the roadway is closed to prevent slurry leakage. The construction site is selected in a roadway with a certain inclination and a sloping slope; the cutting depth is 300~500cm, and the plank wall 2 is 20~30cm wide and 2~3cm thick.
[0024] Four anchor rods 4 are placed at the top plate 1, bottom plate 3 and two roadway walls 7 in the middle of the construction closed wall, forming a square shape, such as Figure 4 As shown, the bolt hole 9 is made on the bolt, the bolt 4 of the top plate 1 ...
