Wall brushing method for underground continuous wall

Abstract

The invention relates to the field of constructional engineering, in particular to a wall brushing method for an underground continuous wall, which is characterized in that a connecting plate is fixedly arranged on a fixing bracket; the connecting plate is connected with and fixed on an outer vertical plane of a mud scraper of a ladder body of a grooving machine; the width of the connecting plate is not greater than that of the mud scraper; and then the grooving machine starts up, the ladder body of the grooving machine drives the fixing bracket to move upwards and downwards, so that a scrubbing surface of the underground continuous wall can be cleaned and brushed. The wall brushing method has the advantages as follows: bolted connection is adopted, so that convenient disassembly and assembly as well as simple operation can be achieved; a vertical fluctuation hoist of the grooving machine achieves a high speed and a high efficiency and saves a great deal of time in comparison with a crane; the ladder body of the grooving machine is heavier, so that a wall brushing device can utilize weight advantage to remove an obstacle when meeting with the obstacle; the verticality of the grooving machine is very good, so that the thoroughness for wall brushing is ensured, and the wall brushing effect is good; and the process is shortened, and a working face is saved.

Description

technical field

[0001] The invention relates to the field of construction engineering, in particular to a wall-painting method for an underground continuous wall. Background technique

[0002] The construction process of the underground diaphragm wall is carried out according to the unit groove section. When the adjacent unit groove sections are constructed sequentially, a connecting joint will be formed. Because there is wall mud in the groove section, the concrete surface of the connecting joint will be in the concrete during the construction process. A layer of mud skin forms on the surface. In order to ensure a good combination of the concrete poured in the later stage and the concrete poured in the previous stage at the joint position, avoid water leakage, and increase the integrity of the wall, after the completion of the subsequent groove section, the concrete surface of the previous groove section needs to be brushed. Treatment, remove the soil attached to the concr...
