Modular saw chain type cutting box and using method thereof

Abstract

The invention discloses a modular saw chain type cutting box and a using method thereof. The cutting box comprises a body module box, a front end module box, a rear end module box and a saw chain set;the front end module box is detachably installed at the front end of the body module box; the rear end module box is detachably installed at the rear end of the body module box; a front slide rail isarranged on the outer side of the front end module box in the height direction; a rear slide rail is arranged on the outer side of the rear end module box in the height direction; the saw chain set comprises a chain and cutters installed on the chain at certain intervals; and the chain is encircled on the front slide rail and the rear slide rail to form closed loop chain transmission. The modularsaw chain type cutting box and the using method thereof can achieve modular assembling of the cutting box, can be suitable for continuous wall construction of mud protecting walls, and can be also besuitable for continuous wall construction of synchronous cutting pouring concrete.

AI Technical Summary

Problems solved by technology

[0002] At present, the grooves of reinforced concrete ground connecting walls are protected by artificial mud to ensure the stability of the groove walls. After the concrete is poured, even if a large amount of mud is recovered and processed for secondary treatment, a large amount of waste slurry will still be generated. If the waste slurry is directly disposed of Outward discharge is not conducive to green construction

The ground connection wall is generally used as the enclosure structure of the foundation pit and the water-stop system of the side wall. The traditional ground connection wall is designed in frames during construction. Seams often become frequent nodes of foundation pit leakage, resulting in potential safety hazards after foundation pit excavation

[0003] In order to solve the problem of construction mud pollution and the potential safety hazards caused by the leakage of the framing ground connection wall, the prior art has emerged a process of synchronously cutting and pouring the concrete floor connection wall, which can realize the cutting and drainage of the soil without a large amount of wall protection mud. Perfusion is performed synchronously

However, the cutting boxes used in the process of synchronously cutting and pouring concrete floor connecting walls are all integrated structures, and a single cutting box has the problems of large size, poor processing technology, high manufacturing cost, and inability to adapt to changes in various groove widths.

[0004] In addition, when using the process of synchronous cutting and pouring concrete ground connection wall, it is necessary to balance the earth pressure by cutting the side wall of the box to prevent the groove from collapsing. However, if the gap between the side wall of the cutting box and the groove wall is unreasonable or the friction resistance with the soil In this case, there will be a risk of the cutting box burying the drill, and because the cutting box is an integrated structure, the cutting box without a large amount of wall protection mud cannot be switched to a mud wall to ensure the stability of the groove wall
