Description

Groove end cleaning device for construction of underground diaphragm wall

Technical Field

The utility model relates to a grooving mechanical equipment field of underground continuous wall construction usefulness specifically says that a groove end that construction underground continuous wall used is exactly the cleaning device at the connection position between two groove sections.

Background

The underground continuous wall is a mature underground building structure, is mainly applied to an enclosure structure of a foundation pit, an outer wall of a basement of a building and the like, and has the functions of preventing external soil from moving towards the foundation pit or the basement and preventing underground water from moving towards the foundation pit or the basement.

The general construction method of the underground continuous wall is as follows: excavating odd unit groove sections with certain length, width and depth underground by using grooving equipment such as a bucket excavator or a slot milling machine, synchronously adopting slurry to protect walls in the grooving process, placing the reinforcement cage into the odd unit groove sections, and pouring concrete by using a guide pipe to form an odd reinforced concrete wall, which is also called as an odd reinforced concrete groove section in the industry; then, even number unit groove sections are dug between two sections of the reinforced concrete wall panels in odd number, the slurry is used for protecting the wall in the digging process, then the reinforced concrete wall panels in even number are placed in the reinforced concrete cages, and concrete is poured by the guide pipes, so that the reinforced concrete wall panels in even number are formed, and the reinforced concrete wall panels in even number are also called as the reinforced concrete groove sections in even number in the industry. At the moment, the odd and even sections of reinforced concrete wall panels jointly form a horizontally extending and continuous reinforced concrete wall.

However, even number unit groove section is at the excavation in-process, and the position that its front and back both ends are close to the reinforced concrete wall width of odd number section often can silt mud, crust, so before transferring even number section steel reinforcement cage and pouring concrete, need the silt clean up at even number unit groove section both ends, otherwise can press from both sides too much influence the intensity and the bearing capacity of last underground continuous wall. In the prior art, scrapers or brushes are generally welded on the back surfaces of two buckets of a groover, the two buckets are closed after excavation is finished, then the buckets are quickly lifted, and sludge is scraped clean by using the brushes or the scrapers on the back surfaces of the buckets; or the milling cutter wheel of the slotter is used for cutting off the sludge at the two ends of the even number unit slot sections in a rotating way.

Both of the above two treatment methods have disadvantages: the weight average of a bucket of the groover and a milling cutter wheel of the groove milling machine is large, the lifting and mud scraping energy consumption is large, the mud scraping process occupies the groover and the groove milling machine, the construction period is delayed, the machine shift cost is increased, and the economic benefit is poor; moreover, the lifting and mud scraping effects of the excavator bucket are not good, the resistance of one side close to concrete is large, and the excavator bucket is easily blocked to shift to the middle of even unit groove sections; the milling cutter wheel of the slot milling machine cannot be deviated inwards, but the milling cutter wheel can simultaneously scrape mud and cut and damage the concrete of the odd sections of the reinforced concrete wall, thereby causing waste.
