Description

Technical Field

[0001] The invention belongs to the technical field of anti-seepage wall construction, and in particular relates to a dock anti-seepage wall construction method which can adapt to various geologies. Background Art

[0002] In the prior art, the guide wall in the construction of the anti-seepage wall is cast on site, and the guide wall construction procedure is: leveling the site → measuring and determining the plane position of the guide wall → digging the guide ditch → erecting the formwork → re-measurement → pouring concrete → removing the formwork → backfilling the outer side of the guide wall and compacting it. Since the cast-in-place guide wall is long (generally tens of meters), it is very difficult to repurpose it. In addition, the guide wall needs to be cured for several days after casting before it can be put into use, which affects the efficiency of the anti-seepage wall construction.

[0003] The anti-seepage wall is usually cast with concrete, and the purpose of building a large-span anti-seepage wall is achieved through segmented construction. The adjacent anti-seepage wall sections are connected by the joint pipe method, and a joint pipe is set in advance at the end of the length of the slot hole of the anti-seepage wall. After the initial setting of the concrete, the joint pipe needs to be pulled out upward to avoid the problem that the joint pipe cannot be pulled out after the concrete is completely solidified. In the prior art, a pipe pulling machine is used to fix the upper end of the joint pipe on the surface for direct pipe pulling. The pipe pulling force is usually 350T-450T. This method of pipe pulling requires a very accurate grasp of the initial setting time of the concrete. If you are not careful, the joint pipe may not be pulled out, which will cause the entire joint pipe to be stranded in the stratum, making this section of the anti-seepage wall ineffective, and it is necessary to rebuild the anti-seepage wall next to it, which will invest huge costs.

In the process of pulling the joint pipe 3 by the hydraulic pipe pulling machine, the joint pipe 3 is first pulled by the hydraulic pipe pulling machine for five to ten centimeters, and then the joint pipe 3 is moved every 15 to 20 minutes; 6 to 8 hours after the concrete is poured, the joint pipe 3 is pulled out.

[0058] like Figure 4-Figure 6 As shown, the concrete strength detection device includes a pressure detector 4, a ball screw 5, a laser displacement sensor 7 and a controller 13.

If the concrete strength value detected for the first time does not reach the set value, the horizontal plate 8 is moved up or down by the electric telescopic rod 26 at an interval of 10-15 minutes so that the probe 10 is aligned with other detection holes 31 for detection again. The distance between adjacent detection holes 31 is about 10mm, and the concrete strength corresponding to the detection holes 31 can be regarded as the same. During the detection process, the infrared camera 14 transmits the real-time image of the concrete strength detection device to the controller 13, which is convenient for the operator to control.
