Example Embodiment

[0027] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0028] See Figure 2-1~Figure 2-3 , A drill bit of a trenchless drilling rig, which is provided with two sets of antennas with different transmitting frequencies, the first antenna 1 and the second antenna 2. Such as diagram 2-1 As shown, the drill bit is provided with a non-excavation guide probe 3, two sets of antennas are coaxially arranged on one side of the probe 3 in the drill bit, and the battery compartment 4 is located at the other end of the probe 3; Such as Figure 2-2 Shown, with diagram 2-1 The difference is that the battery compartment 4 is located between the two antennas; Figure 2-3 As shown, there are two probes in the drill bit, a first probe 31 and a second probe 32. The first antenna 1 is located in the first probe 31, the second antenna 2 is located in the second probe 32, The first probe 31 and the second probe 32 are coaxially ar...

Abstract

The invention discloses a drill bit of a non-excavation drilling machine. A probe is arranged in the drill bit, and antennas are arranged in the probe. The drill bit of the non-excavation drilling machine is characterized in that the antennas are coaxially arranged, are divided into at least two sets and have different transmitting frequencies. The invention further discloses a positioning method of the drill bit. The two sets of antennas are arranged in the drill bit, according to the translation relationship, the distances between two front points or two rear points of the two sets of antennas and the antennas are the same, and therefore in the whole drilling construction process of the drill bit, an operator can determine the axis direction of the underground probe when moving the drill bit by a small distance (the distance between the two sets of antennas). The moving distance is small, and operation is more convenient, more rapid and safer.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a drill bit of a non-excavation drilling machine, and a positioning method for the drill bit. Background technique [0002] With the large-scale development of urban construction, it is necessary to lay sewage interceptor pipes or energy (liquefied gas, natural gas, etc.) supply pipes in cities. Traffic jams and construction safety hazards exist. [0003] Therefore, the non-excavation pipe laying technology has also been developed and used at present, that is, a construction method of laying, repairing and replacing underground pipelines without digging trenches on the road surface and without destroying a large area of ​​the ground surface by means of geotechnical drilling. technology. The use of trenchless technology has the advantages of short cycle, low cost, less pollution, good safety performance, etc., and will not affect the normal traffic order. [0004] The most widely used trenchl...
