Wall brushing device for milling underground diaphragm wall construction and using method thereof

Abstract

The invention discloses a wall brushing device for milling underground diaphragm wall construction and a using method thereof. The wall brushing device comprises a length adjuster, a left box body, a right box body and a width adjuster, wherein the width adjuster comprises a first partition, the length adjuster comprises a second partition, the left box body comprises a first box body and a second box body, the right box body comprises a third box body and a fourth box body, a plurality of first partitions are arranged between the first box body and the third box body as well as between the second box body and the fourth box body and are connected through bolts, a plurality of second partitions are arranged between the first box body and the second box body as well as between the third box body and the fourth box body and are connected through bolts, and wall brushing devices are respectively arranged on the first box body, the second box body, the third box body and the fourth box body. According to the wall brushing device, the number of the second partitions can be adjusted according to actual working conditions so as to adapt to the wall thickness of an underground diaphragm wall, additionally, the number of the first partitions is adjusted so as to adapt to the actual second-stage groove width, the purpose of improving the wall brushing effect is achieved, and in addition, the wall brushing quality is improved through an eccentric hanging brush.

Description

technical field [0001] The invention relates to the technical field of underground construction equipment, in particular to a wall brushing device for underground continuous wall construction by milling method and a use method thereof. Background technique [0002] As the shallow underground space in some cities in China has basically been utilized, and the deep excavation technology and equipment have been gradually improved, it has become possible to divide the underground space vertically and develop gradually into deep layers. In the development of urban deep underground space, ultra-deep foundation pit engineering is unavoidable, but in urban areas with soft soil geological conditions, affected by factors such as large excavation depth, complex surrounding environment, small site, and high groundwater head pressure, foundation pit engineering During the construction of the pit, the requirements for the strength of the enclosure structure and the water-stop effect are hi...

Problems solved by technology

[0006] However, in the actual construction process of the underground diaphragm wall with the ultra-deep milling method, when the second-stage groove is formed, the age of the concrete on both sides of the first-stage groove is different, which can easily cause the hole to be deflected, and it is often necessary to repair the groove and expand the hole several times

The width of the final second-stage groove section is generally larger than the design value, and the joint surface of the first-stage and second-stage grooves is not an ideal plane. often poor

[0007] In addition, the wall thickness of the underground continuous wall of the ultra-deep milling method is often different according to the design requirements, even in the same project, there are also different thicknesses, and the existing wall brushes cannot meet most of the wall thickness dimensions; for example, the publication number is CN207452884U The double-wheel groove milling machine underground diaphragm wall construction can only carry out the adjustment of the wall thickness direction of the underground diaphragm wall with the wall brusher of the double-wheel groove milling machine, and cannot satisfy the change on the groove width direction of the second phase; another example is a kind of underground diaphragm wall whose publication number is CN112523217A Exist above-mentioned problem equally in the brush wall device and the wall brushing method of

[0008] In order to solve the above problems, the present invention provides a wall brushing device for underground diaphragm wall construction by milling method and its use method to solve the problem that previous wall brushing devices cannot adapt to underground diaphragm walls of different thicknesses and second-stage grooves due to groove repairing and reaming. serious problem
