e. and c, repeating the steps c and d, and sequentially performing press-in construction of the next locking type high polymer impervious wall forming groove plate, pulling out of the front locking type high polymer impervious wall forming groove plate in the current state and synchronous grouting construction until the whole locking type high polymer impervious wall construction is finished.

Further, in the steps a-c, at least the alignment locking and the pressing of the two locking type high polymer impervious wall forming groove plates are completed, and then the grouting operation of the front locking type high polymer impervious wall forming groove plate is carried out.

In summary, the present embodiment performs the pressing-down construction of the locking type polymer cut-off wall forming groove plate by the pile driver with the vibration hammer.

In the step d, the locking type high polymer impervious wall forming groove plate at the front end is firstly pulled out by 10 cm-50 cm, then a grouting machine is opened to start grouting, and the locking type high polymer impervious wall forming groove plate is slowly pulled out in a high-frequency vibration mode while grouting.

In step e, the locking type high polymer impervious wall forming groove plate pulled out in the step d is used as the next locking type high polymer impervious wall forming groove plate for repeated use, and meanwhile, a grouting pipe in the pulled locking type high polymer impervious wall forming groove plate is replaced, and a new anti-blocking head and a new anti-blocking plug are configured.

The following is described in detail with reference to specific construction:

the specific structure of the forming groove plate is as follows:

a hollow steel pipe with the diameter of 5cm is welded at the back of the formed groove plate to form a guide pipe, and a grouting pipe with the diameter of 8mm is placed inside the guide pipe, as shown in figures 1 and 2.

Hard plastics are filled between the guide pipes and the grouting pipes at the top and the tail parts to prevent slurry from flowing back to the gap between the grouting pipes and the outer iron pipe in the grouting process, and further blocking the grouting pipes and the steel pipes.

In order to prevent the problem that the soil body can enter the grouting pipe during the pressing-in process and block up the grouting pipe, a hollow conical anti-blocking head is arranged at the bottom of the guide pipe and is not directly adhered with the molding groove plate and the grouting pipe, a notch with the width consistent with the diameter of the conical anti-blocking head is specially cut on the molding groove plate, iron blocks/rings are respectively welded on two sides of the guide pipe to form a stop block for fixing the anti-blocking head, the molding groove plate in the structure is a steel plate, and the guide pipe is a steel pipe. When the molding groove plate is pressed into the soil body, the anti-blocking head is tightly connected with the guide pipe under the action of the reaction force of the soil body, so that the soil body is prevented from entering and blocking the grouting pipe. And the anti-blocking head can automatically fall off in the lifting process of the molding groove plate, and the slurry can be smoothly injected into a hollow groove formed by the molding groove plate to form a high polymer impervious wall.

Pressing in/pulling out equipment:

in this embodiment, the forming groove plate is clamped by a pile driver provided with a vibration hammer, and then the bottom of the forming groove plate is pressed downwards into the ground in a high-frequency vibration mode.

(3) The grouting wall forming method comprises the following steps:

after the first modified forming slotted plate is pressed into the ground, the second forming slotted plate is locked and embedded with the first plate by using the locking lugs, and then the second forming slotted plate and the third forming slotted plate are sequentially pressed into the ground in the same way. The locking manner is shown in fig. 5, and the schematic drawing of the pressing-in process is shown in fig. 6 and 7.

And then connecting the grouting pipe of the first grooved plate with a grouting machine, slowly pulling out the first grooved plate by using a pile driver, starting the grouting machine to perform grouting when the first grooved plate is pulled out upwards by 30cm, and slowly pulling out the formed grooved plate in a high-frequency vibration mode while performing grouting. As shown in fig. 9.

When the first forming groove plate is completely pulled out, the second forming groove plate is pulled out in the same way.

The grouting pipe at the back of the first formed groove plate is replaced and modified into the mode shown in figures 1 and 2. Then the third forming groove plate and the third forming groove plate are pressed into the ground again in a locking and embedding mode.

And then repeating the steps until the high polymer ultrathin impervious wall is finished. The complete schematic is shown in fig. 8 and 9.

The term "and/or" herein means that three relationships may exist. For example, a and/or B may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
