Construction method of concrete diaphragm wall in mucky soil body with high water content

Abstract

The invention relates to the field of concrete, and particularly discloses a construction method of a concrete diaphragm wall in a high-water-content mucky soil body, which comprises the following steps: (1) constructing a guide wall; (2) preparing wall-fixing slurry; (3) forming holes and grooves; (4) cleaning the bottom and changing pulp; (5) joint construction; (6) manufacturing and installing a reinforcement cage; (7) pouring concrete, wherein the plastic concrete in the step (7) comprises the following components in parts by weight: 160-320 parts of cement; 220 to 420 parts of clay; 125 to 250 parts of bentonite; 1250 to 1580 parts of sand; 1270 to 1505 parts of broken stone; 15 to 30 parts of aminocyclopropane carboxylic acid; 25 to 40 parts of sodium aluminate; 35 to 55 parts of polyvinyl alcohol; 4-15 parts of an expanding agent; 2-8 parts of a water reducing agent; and 650 to 825 parts of water. The concrete anti-seepage wall has the effect that the bearing capacity of the concrete anti-seepage wall is not prone to being affected.

Description

technical field [0001] The application relates to the technical field of concrete, more specifically, it relates to a method for constructing a concrete anti-seepage wall in muddy soil with high water content. Background technique [0002] The concrete cut-off wall is an underground continuous wall that is built by pouring concrete or backfilling other anti-seepage materials under the mud with mud-solid walls in loose permeable foundations or earth-rock dam dams. [0003] However, in the existing construction method of pouring plastic concrete cut-off walls in silty soil with high moisture content, due to the long solidification time of the concrete, the concrete has not yet solidified after the concrete is poured, making the concrete cut-off walls easy to sink , so that the bearing capacity of the concrete cut-off wall is affected. Therefore, there is still room for improvement. Contents of the invention [0004] In order to make the bearing capacity of the concrete cut...
