[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The erosion and damage of the water flow of a large river to the river bank slope surface can lead to land loss, bank slope collapse and other problems. Therefore, it is of great significance to take appropriate protection measures to protect the safety of the river bank and the surrounding environment.

[0031] In order to effectively prevent the erosion of the river bank, especially the large river or the river into the sea under the high-speed water flow, a deep concrete sheet pile is inserted at the toe of the slope or the toe of the embankment to prevent the erosion and collapse of the bank slope and prevent seepage.

[0032] The concrete sheet pile structure inserted into the bank of a river, lake or sea can effectively prevent the erosion of the river. Its characteristics are as follows: 1. strong and durable: the concrete sheet pile revetment has strong anti-erosion and bearing capacity, and can protect the river bank for a long time. 2. simple construction: the concrete sheet pile revetment is convenient to construct, can be adjusted according to the actual situation, and is suitable for various types of river banks. 3. easy to maintain: the concrete sheet pile revetment is easy to maintain, only needs to be checked and repaired regularly.

[0033] The construction method of the concrete sheet pile revetment needs the following steps:

[0034] 1. Determine the construction position: determine the construction position of the concrete sheet pile revetment according to the actual situation, and perform necessary topographic survey and design.

[0035] 2. Insert the concrete sheet pile into the design top elevation:

[0036] (1) If the ground layer in the sheet pile construction area is hard and not easy to insert and sink the sheet pile, a pilot hole can be inserted at the set construction position of the sheet pile;

[0037] (2) Then use the pile driver or pile driver to drive the sheet pile to the set elevation, and the shape, size and number of the sheet pile should be determined according to the water flow velocity and soil conditions of the river.

[0038] (3) If the ground layer is relatively soft, the pile sinking during the sheet pile insertion construction is easy, and the sheet pile can be directly hoisted and vertically positioned without pre-pilot hole, and the pile driver or pile driver is used to drive the sheet pile to the set elevation.

[0039] 3. Gap grouting between sheet piles: In order to achieve the anti-seepage effect of the concrete sheet pile, cement mortar or resin mortar is used to grout the gap between adjacent sheet piles to 0.3m below the scour line.

[0040] 4. Confirm the construction quality: Confirm the construction quality to ensure the anti-scouring and bearing capacity of the concrete sheet pile revetment.

[0041] In some special cases, in order to prevent the slope foot and the sheet pile from being washed away and damaged as much as possible, it is necessary to take a deeper sinking sheet pile to resist the corresponding anti-scouring damage and increase the stability and safety of the pile foundation.

[0042] For the construction of the super-long concrete sheet pile with deep sinking pile, the geological conditions are often complex, and there may be soft soil layer, block stone layer, "iron plate sand" layer and other unfavorable factors. These factors will increase the construction difficulty, and there may be pile sinking difficulty, pile body damage, pile deviation and other phenomena during the construction of the concrete sheet pile. Therefore, how to avoid these phenomena and ensure the perpendicularity of the sheet pile, the joint width and other parameters is one of the difficulties in the construction of the sheet pile.

[0043] In addition, the shoreline of some rivers is mostly curved, and it is difficult to tightly sink the concrete sheet pile along the shoreline under the non-straight line. In addition, during the construction of the sheet pile, the traditional method of using the level to release the pile top elevation line and using the visual control method of the pile driver operator to control the elevation is easy to be affected by the surrounding noisy environment, and the elevation control error is large. Therefore, how to ensure the accuracy of the elevation control of the sheet pile is also a difficulty in the construction of the sheet pile.

[0044] In order to overcome various difficulties in the construction of the concrete sheet pile, ensure that the perpendicularity is always maintained during the sinking process of the inserted sheet pile, and there is no horizontal deviation along the riverbank, and the joint between adjacent sheet piles is tight, the application provides a guide frame for ensuring the construction quality of the concrete sheet pile, and is applied in the construction of the sheet pile, solves the above construction difficulties, and ensures the construction quality.
