Description
Technical Field
The invention relates to the technical field of underground continuous wall construction, in particular to a wall brushing device and a wall brushing method for an underground continuous wall.
Background
The underground continuous wall is a continuous wall which is arranged below the ground and is constructed for intercepting water, preventing seepage, retaining soil and bearing weight. In the specific construction, the underground continuous wall is divided into a plurality of unit groove sections along the length direction of the underground continuous wall, then a unit wall body is formed in each unit groove section, and a plurality of unit wall bodies are sequentially connected to form the underground continuous wall.
At present, the grooving process of the underground diaphragm wall mainly adopts a grab bucket grooving process and a 'grab and milling combined' grooving process. The grab grooving process has the advantages that the weight of the grab grooving machine body is large, the length of the machine body is long, dynamic deviation rectification can be achieved, and the grooving perpendicularity is greatly improved. However, as the depth of the underground continuous wall becomes deeper and deeper, the grab bucket grooving process is not suitable for the construction of the ultra-deep underground continuous wall, particularly the ultra-deep underground continuous wall with the depth of more than 60 meters. The 'grabbing and milling combined' process is suitable for ultra-deep underground continuous walls and underground continuous walls in soft soil areas, and meets the requirements of grooving perpendicularity, sediment thickness and the like.
As shown in fig. 1 and 2, the underground diaphragm wall includes three sections of unit walls, i.e., two sections of first-stage walls 1 and one section of second-stage walls 3, and the second-stage walls 3 are located between the two sections of first-stage walls 1. When the grooving construction of the first-stage wall 1 is carried out, the 'grabbing and milling combination' grooving is adopted, and a soil body is directly grabbed by a grab bucket grooving machine on a soil layer above 7 layers; after the soil enters 7 layers of soil, the soil is milled by a hydraulic groove milling machine. For the grooving construction of the second-stage wall 3, after the first-stage walls 1 on two sides reach the maintenance age, a groove milling machine is directly adopted to mill soil in the second-stage groove section 2 and roughen concrete wall surfaces of the first-stage walls 1 connected with the second-stage walls 3, and although the concrete wall surfaces are relatively straight on the whole, due to the existence of cutter marks of milling cutters, pits and concave pits are formed in the concrete wall surfaces, so that muck is easily accumulated in the pits, and the muck is not easy to clean. More or less attachments such as dregs exist at the joint parts between the groove sections. The sources of these muck attachments mainly include: on the first hand, the flow of the concrete of the unit wall in the pouring process pushes the slag soil to the joint of the groove section; and in the second aspect, the muck left in the excavation process of the groove section is the muck on the concrete wall surface of the joint part. Generally, the length of the first-stage wall is 6600mm, the length of the second-stage groove section is 2200mm, the two first-stage walls are respectively roughened by 300mm, the length of the second-stage wall is 2800mm, and the wall thickness is 1200 mm.
In the process of constructing a first-stage wall, if backfill on one side of the fore shaft pipe is not dense or not in place, an assembly gap exists at the joint of the fore shaft pipe formed by connecting multiple sections, concrete flowing in the concrete pouring process of the first-stage wall can generate extrusion force on the fore shaft pipe, so that the fore shaft pipe can bend, the surface of the fore shaft pipe cannot keep a vertical state, and sometimes, because the flowing concrete extrusion force can displace together with fore shaft pipe jacking equipment, the fore shaft pipe inclines, the actual condition of a concrete wall surface at the joint is probably not a vertical line of a vertical horizontal plane, or bends or inclines, and the difficulty of cleaning attachments such as slag soil is increased.
The existing mode of clearing attachments such as muck is mainly to utilize the self weight of a wall brushing device, the wall brushing device is enabled to clear up the concrete wall surface vertically and vertically as far as possible, and the wall brushing device consisting of a plurality of rows of steel wire brushes can not effectively adhere to the surface of the concrete wall surface to move up and down under the condition of no lateral pressure for the concrete wall surface which is not originally a vertical line. Therefore, wall brushing cleaning is a crucial link in the construction of the underground continuous wall, and the cleaning effect on attachments on the surface of the concrete wall at the connecting part directly influences the quality of water interception, seepage prevention and soil retaining and bearing of the underground continuous wall structure.

s2, connecting the connecting unit 5 to the grab bucket 41 of the grab bucket grooving machine 4;
s3, connecting the brush wall unit 6 to the connecting unit 5;
and S4, starting the grab bucket trenching machine 4 to enable the wall brushing unit 6 to move up and down along the wall to be cleaned so as to clean attachments on the wall.
According to the wall brushing method for the underground continuous wall, the wall brushing unit 6 is detachably connected to the grab bucket 41 of the grab bucket grooving machine 4, so that the weight of the body of the grab bucket grooving machine 4 can be fully utilized, the wall brushing unit 6 is effectively controlled to be tightly attached to the concrete wall surface at the joint position of the underground continuous wall, attachments such as muck and the like on the concrete wall surface are effectively cleaned, and the wall brushing effect of the wall brushing device is improved.
The wall brushing device and the wall brushing method for the underground diaphragm wall provided by the invention are not only suitable for foundation pits with conventional depths, but also can avoid the phenomenon that the hoisting depth is usually insufficient if the wall brushing device is hoisted by a crawler crane when the foundation pit with ultra-deep depth is met, and simultaneously save the cost and the working procedure for independently hoisting the wall brushing device by the crawler crane for one day.
In summary, according to the wall brushing device and the wall brushing method for the underground continuous wall provided by the invention, the wall brushing unit 6 is detachably connected to the grab bucket 41 of the grab bucket grooving machine 4, so that the weight of the machine body of the grab bucket grooving machine 4 can be fully utilized, the wall brushing unit 6 is effectively controlled to be tightly attached to the concrete wall surface at the joint position of the underground continuous wall, and attachments such as dregs and the like on the concrete wall surface are effectively cleaned, thereby improving the wall brushing effect of the wall brushing device.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the present invention.
