[0019] Description of reference numerals: DETAILED DESCRIPTION

[0020] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The following is combined with Figure 1 The present invention is described in further detail.

[0022] The embodiment of the present invention discloses a method for constructing an anti-sliding pile prestressed anchor cable. Figure 1 The anti-sliding pile prestressed anchor cable construction method includes a pad 1, and support plates 2 supported on the side walls of the anti-sliding pile are arranged on both sides of the pad 1. The pad 1 is provided with a reserved hole 11 for the anchor cable to pass through. The construction method adopts the following steps:

[0023] Step 1: Processing the pier: cutting the steel plate into the shape of the pier 1, processing the support plate 2 into a right triangle, and fixing the long right-angled sides of the support plate 2 on both sides of the pier 1;

[0024] Step 2: fix the cushion pier to the side wall of the anti-slip pile, support the support plate 2 on the anti-slip pile, align the reserved hole 11 with the anchor hole, and make the central axis of the anchor hole perpendicular to the cushion plate 1;

[0025] Step 3: insert the anchor cable clamp into the reserved hole 11 of the backing plate 1 and fix it;

[0026] Step 4: The operator controls the jack to pre-tighten the anchor cable so that the pad 1 and the anchor cable clamp are corrected and positioned to complete the anchor cable tensioning;

[0027] The concrete pad and steel pad of the anchor cable are combined into one; the installation process of this device before prestressed anchor cable tensioning is simple and can be installed by one person; after the anchor clamp is installed in place, the oil pump operator can complete the correction and positioning of the steel pad and anchor clamp by controlling the jack, and then complete the anchor cable tensioning work.

[0028] In this embodiment, two groups of mounting clamps 12 are arranged on both sides of the base plate 1, and the two support plates 2 are respectively installed in the two groups of mounting clamps 12. The position of the support plate 2 between the mounting clamps 12 is adjustable. By adjusting the position of the support plate 2 between the two mounting clamps 12, the supporting angle of the support plate 2 can be adjusted, so that the base plate 1 can always maintain a vertical state with the central axis of the anchor hole when it is installed on the side wall of the anti-slip pile.

[0029] In this embodiment, the acute-angle end of the support plate 2 is rotatably arranged between two mounting clamps 12. The support plate 2 can be rotated around the acute-angle end of the support plate 2 between the two mounting clamps 12 to adjust the angle between the pad 1 and the side wall of the anti-slip pile so that the central axis of the anchor hole is perpendicular to the pad 1. The support plate 2 can be fixed between the mounting clamps 12. By rotating the support plate 2, the angle of the support plate 2 between the mounting clamps 12 is adjusted. After the angle is adjusted appropriately, the support plate 2 is fixed in the mounting clamps 12.

[0030] In this embodiment, the acute-angle end of the support plate 2 is configured in the form of an arc to prevent the sharp end from causing harm to the operator during use.

[0031] In this embodiment, the two support plates 2 are connected with a connecting rod 3 at a position away from the acute-angle end. The mounting clamp 12 is provided with an arc groove 13 for the connecting rod 3 to move when the support plate 2 rotates. The connecting rod 3 passes through the arc groove 13. The two support plates 2 can be rotated synchronously through the connecting rod 3, so that the supporting angles of the two support plates 2 are the same. At the same time, in order to make the rotation angle of the support plates 2 more accurate, a ruler can also be provided on the side of the arc groove 13. The pad 1 is placed on the anchor hole, and the angle of the pad 1 is adjusted by rotating the support plate 2. After the angle is suitable, the scale position of the connecting rod 3 is recorded. After the pad pier is removed, the support plate 2 is adjusted into place and fixed according to the recorded scale position.

[0032] In this embodiment, the two inner mounting clamps 12 are slidably arranged on the pad 1, and the pad 1 is provided with a T-slot for the mounting clamp 12 to move. The connecting rod 3 is threadedly matched with a locking nut 31 near the two ends. When the locking nut 31 is rotated, it can push the mounting clamp 12 to move and cooperate with another fixed mounting clamp 12 to clamp the support plate 2. When the angle of the support plate 2 needs to be adjusted, the locking nut 31 is loosened so that the movable mounting clamp 12 can leave the support plate 2, so that the support plate 2 can rotate. After the angle is adjusted to a suitable level, the locking nut 31 is tightened. During the tightening process, the locking nut 31 pushes the mounting clamp 12 to move and press against the support plate 2, thereby clamping the support plate 2.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
