[0050] like Figures 1 to 5 As shown, this embodiment provides a method for installing an inclined single-sided formwork, comprising the following steps:

[0051] S10: construct anchor cables and bolt anchor rods from top to bottom along the slope 11;

[0052] S20: Installing and supporting the formwork in layers from bottom to top along the inclined surface 11, pouring concrete in advance after each layer of formwork is installed and supported, and pouring concrete for the next layer after the concrete solidifies;

[0053] S30: After the concrete solidification strength reaches the preset strength, a curing agent is applied to the surface for curing. The formwork is removed after it is completely solidified, and the construction joints are treated.

[0054] In this embodiment, anchor cables and bolt anchor rods are constructed first, which is conducive to the layered installation and support of the formwork. Concrete is poured in layers by supporting the formwork, which solves the problems of difficulty in one-time pouring and the inability to ensure safety and quality. Compared with pouring concrete at one time, pouring concrete in layers by supporting the formwork can speed up the construction flow and solve the problem of slow progress.

[0055] It should be noted that in order to ensure the strength and quality of concrete after pouring, steel mesh is usually laid on the slope.

[0056] In some embodiments, Figure 1 As shown, in step S10, the construction of anchor cables and bolt anchor rods from top to bottom along the slope includes the following steps:

[0062] In some embodiments, to ensure construction quality and efficiency, the specifications of the first row of bolt anchors and the second row of bolt anchors are preferably C14@1500, wherein C14 represents that the diameter of the anchor is 14 mm, and “@1500” represents that the horizontal spacing of the anchors is 1500 mm.

[0063] In some embodiments, in order to ensure the firmness of the first row of bolt anchors 12 and the second row of bolt anchors 13, the depth of the first row of bolt anchors 12 and the second row of bolt anchors 13 into the ground is 2m. Furthermore, in order to facilitate the connection of the first row of bolt anchors 12 and the second row of bolt anchors 13 with the formwork, it is preferred that the exposed lengths of the first row of bolt anchors 12 and the second row of bolt anchors 13 are both 0.5m.

[0074] In some embodiments, in order to facilitate the fixation of the first diagonal brace 17, at least two rows of supporting steel pipes 16 are driven into the inter-slope platform 10. The specifications of the first diagonal brace 17 and the supporting steel pipes 16 are both 48mm*3.5mm steel pipes. The depth of the supporting steel pipes 16 driven into the inter-slope platform 10 is not less than 1m. Figure 1 As shown, L1≥1m.

[0076] In some embodiments, the height of the first layer of poured concrete 20 above the inter-slope platform 10 is L3, preferably L2+L3 is equal to 1.5 m, and when L2=0.5 m, L3=1 m.

[0077] In some embodiments, after the first layer of formwork 18 is set up and the first layer of concrete is poured, after the first layer of poured concrete 20 solidifies and reaches a preset strength, a curing agent is applied to the surface for curing, and the formwork is removed after complete solidification, and the construction joints are treated. After the treatment is completed, the second layer of formwork 22 is installed and set up and the second layer of concrete is poured.

[0081] S223: Arrange a pre-buried steel pipe 31, wherein the pre-buried steel pipe 31 extends horizontally out of the outside of the second layer formwork 22, and pour a second layer of concrete.

[0082] In some embodiments, the fixing method of the second diagonal brace 21 is similar to the fixing method of the first diagonal brace 17, that is, at least two rows of supporting steel pipes 16 are also driven into the inter-slope platform 10, and the specifications of the second diagonal brace 21 and the supporting steel pipes 16 are both 48mm*3.6mm steel pipes, wherein the depth of the supporting steel pipes 16 driven into the inter-slope platform 10 is not less than 1m.

[0083] In some embodiments, in order to further strengthen the support of the second layer formwork 22, a first die-cast steel pipe 23 is provided on the outer surface of the second layer formwork 22, and the first die-cast steel pipe 23 is connected to the embedded bolts 19 and the second row of bolt anchor rods 13; further, the first die-cast steel pipe 23 is welded to the steel mesh by fastening bolts to further realize the support firmness of the second layer formwork 22.

[0084] In some embodiments, considering the convenience of pouring the third layer of concrete, a pre-buried steel pipe 31 is set 1m below the second layer of concrete, and a filter bag is set at the bottom of the pre-buried steel pipe 31, which can also be used as a later drainage pipe. Finally, the second layer of concrete is poured, and the second layer construction joint is treated after the formwork is removed and maintained. After the treatment is completed, the installation and support of the third layer of formwork 29 and the pouring of the third layer of concrete are started.

[0085] In some embodiments, in step S23, after the second layer of concrete solidifies, the third layer of formwork is installed and supported, and the steps of completing the pouring of the third layer of concrete include:
