Embodiment Construction

[0057] Examples see figure 1 , figure 2 As shown, the drill bit for guiding horizontal rotary spraying construction includes a drill body 29 and a wedge plate 6 fixedly connected to the head of the drill body. In the drill body, a high-pressure water channel 2 and a high-pressure slurry channel 4 are arranged axially. The high-pressure water channel 2 is provided with a water spray nozzle 3 laterally, the high-pressure slurry channel 4 is provided with a spray nozzle 5 laterally, and a groove 30 is provided on the side wall of the main body of the drill bit, and an inherent probe 1 is embedded in the groove, see Figure 8 , The outer surface of the probe 1 is covered with a rubber hose 28, and the rubber hose is tightly connected with the probe through a pipe collar 27. Such as figure 1 As shown, the drill adopts a concentric circle structure and consists of 6 parts. The wedge plate 6 is integrated with the drill bit by welding, and about Φ8-12mm water holes are opened on ...

Abstract

The invention discloses a drilling bit for guiding horizontal rotatably-jetting construction and a construction method thereof. The drilling bit comprises a drilling bit main body and a wedged plate which is fixedly connected to the head of the drilling bit main body; the side wall of the drilling bit main body is also provided with a groove; a probe is embedded in the groove and provided with a wireless transmitter; a signal transmitted by the wireless transmitter is acquired by a wireless data acquiring instrument which is in signal connection with a displayer through a high-frequency wireless transmitting module and an antenna; and the wireless data acquiring instrument is connected with the INTERNET through GPRS (Global Position System). The invention can determine the driving direction of the drilling bit and the concrete position of a spraying nozzle, can change the drilling direction, automatically rectify a deviation and carry out long-distance operation on a horizontal rotatably-jetting pile with high precision if necessary, can additionally jet in a specific direction according to the direction and ensure the safe construction of tunnels or other underground projects.

Description

technical field [0001] The invention relates to a drill bit for rotary spraying construction and a rotary spraying construction method thereof. Background technique [0002] Horizontal jet grouting is a new type of rock and soil reinforcement technology that has emerged in recent years. It is developed from vertical jet grouting. , The grouting pipe is nearly horizontal, and the nozzle is sprayed and grouted from the inside to the outside. The horizontal consolidated body formed by the horizontal rotary grouting can well strengthen the rigidity of the structure, support the upper soil, and has a certain anti-seepage and water-proof performance, which has a broad application prospect. However, in the past, when the horizontal rotary spraying was used for drilling construction, it was necessary to form a hole first and then carry out rotary spraying, and the drilling depth was only more than ten meters, which caused the disadvantages of high production cost and low efficiency...
