Aiming at the problems of door closing collapse, undetermined karst or collapse and other emergency rescue in the existing underground engineering, the embodiment of the invention provides an underground engineering emergency rescue method based on a horizontal directional drill, which can quickly respond to the emergency rescue under the emergency.
Referring to fig. 1, a flow chart of an underground engineering emergency rescue method based on a horizontal directional drill in an embodiment of the invention is shown, and specifically the method comprises the following steps:
s100, determining the position to be emergency rescue in the underground engineering;
for emergency situations such as door closing collapse, undetermined karst or collapse body and the like of underground engineering, the outside of the internal situation cannot be observed, trapped personnel or engineering emergency situations in the underground engineering can be subjected to rescue, and the position information of the trapped personnel or emergency rescue of props must be known first.
For the emergency of door closing collapse, the position of the trapped person in the underground engineering can be determined naturally through communication equipment and the like under the condition that the trapped person can communicate by using other equipment. However, in some cases, normal communication and the like may be damaged due to emergency situations such as door closing collapse, in which case, a life detector may be used to detect, and the position of the trapped person in the door closing collapse body is determined according to the life signal, so as to provide conditions for subsequent rescue.
For unexpected karst or collapse and other emergency conditions, the position of the karst or collapse can be determined by adopting a conventional engineering exploration method, such as the existing drilling method, physical exploration method and the like, the position of the karst or collapse in the underground engineering is determined after the karst or collapse is ascertained, and the position of the karst or collapse is determined, namely the position to be subjected to emergency rescue, so that subsequent rescue is facilitated.
S200, rapidly drilling the underground engineering from the outside by utilizing a horizontal directional drill according to the determined position to be subjected to emergency rescue, so as to form a communication channel between the position of the device to be subjected to emergency rescue and the outside;
for the situation of door closing collapse, after the position of trapped personnel is determined, a horizontal directional drill can be arranged outside the door closing collapse body, and a communication channel is formed when the horizontal directional drill quickly drills to the position of the trapped personnel, namely the position to be subjected to emergency rescue.
And (3) under the conditions of undetermined karst or collapse body and the like, after the position of the karst or collapse body is determined, arranging a horizontal directional drill to quickly drill the karst or collapse body from the outside of the karst or collapse body, and then forming a communication channel at the position to be emergency-rescuing where the karst or collapse body is located.
The horizontal directional drill can rapidly and flexibly penetrate through a door closing collapse body and the like under the condition of not erecting a construction platform, and can rapidly reach the position of karst or collapse body. Moreover, the horizontal directional drilling machine has the characteristics of miniaturization, flexibility and mobility, can adapt to a narrow and limited space in underground engineering, is convenient to mechanically transfer, can automatically advance to the front of a door closing collapse body under the drive of an integral motor, can start operation on the existing construction operation surface, saves the time of erecting a traditional drilling machine construction operation support platform, and further effectively saves time for preparing work for emergency rescue.
S300, emergency rescue is carried out by using the communication channel.
The communication channel is formed by S200, and the channel can be used for rescue channels, for example, ventilation oxygen is provided for trapped people by using the communication channel, and emergency articles (food, water, medicines and the like) are conveyed. In some cases, if the conditions allow, the diameter of the formed channel is sufficiently large, it is also possible to consider direct personnel rescue. It can be said that a life channel is formed by means of the horizontal directional drill. According to the embodiment, for the emergency situations of the underground engineering such as door closing collapse and the like, horizontal directional drilling is adopted to form a communication channel as a life channel of trapped personnel, emergency rescue under the emergency situations can be responded quickly, and the device has the characteristics of miniaturization, flexibility, maneuver and quick response.
And the communication channel is formed by adopting the S200, and the channel can be used for carrying out emergency treatment on unexpected karst or collapse and other emergency conditions, for example, grouting is carried out rapidly through the channel to carry out emergency rescue, and the karst or collapse is filled through grouting, so that engineering risks are reduced.
In some preferred embodiments, S200 may employ a guiding system to guide the drilling direction of the horizontal directional drill in order to more precisely form the communication channel by the horizontal directional drill before the closed door collapse, the undetermined karst or the collapse of the underground works is quickly drilled by the horizontal directional drill. Specifically, the following steps may be referred to:

The guidance system may be selected from prior art implementations such as a hand-held tracking system, a cabled guidance system. The hand-held tracking system is convenient to use, but operators need to directly reach the ground above the drill bit, and is easily limited by terrain, electromagnetic interference and detection depth, so that the hand-held tracking system is more suitable for small and medium-sized horizontal directional drills. The cable-type guiding system can span any terrain without electromagnetic interference, but is complex, troublesome to use, low in efficiency, high in price, higher in precision and data processing speed, and suitable for various types of horizontal directional drills.
S202, setting a target point according to the position to be emergency rescue, and planning a guiding route of a guiding system;
in the step, the guiding route is a route from a starting point of a horizontal directional drilling operation to a target point (a horizontal directional drilling operation end point), and the planned guiding route can specifically avoid the existing underground equipment in normal use according to the specific geological conditions of underground engineering (a closed-door collapse body, an undetermined karst or collapse body and the like) and the underground equipment conditions. In a specific planning, the drilling operation of the communication channel is preferably performed with the shortest drilling distance, as conditions allow, eventually opening up the interior and exterior spaces.

In some embodiments, the drilling angle of the on-site horizontal directional drill can be combined with the situation that the life detector acquires the azimuth of the trapped person, and the drilling angle is continuously adjusted so as to realize effective drilling.
In the above embodiment, the horizontal directional drill can quickly penetrate through holes such as the door closing collapse body under the action of the guiding system, and can adjust the drilling angle according to the actual drilling conditions such as actual geology, engineering collapse and the like, and the drilling machine operation of the communication channel is implemented with the shortest drilling distance according to the planned guiding route, so that the internal space and the external space are finally opened.
In some embodiments, the size of the communication channel is selected according to the actual situation, and is determined by the diameter of the horizontal directional drill, for example, the diameter of the horizontal directional drill is about 110-130mm, and accordingly, the diameter of the formed communication channel is also about 110-130mm, and the formed drill is convenient for providing oxygen and food for trapped personnel behind the collapse body or providing grouting. Larger diameter boreholes may be used, as environmental and engineering conditions allow, through which other rescue operations may be performed.
In some embodiments, the pilot bit may change the drilling direction of a horizontal directional drill to which the drill rod is attached, the drill rod being bendable, wherein bending of the drill rod may be guided by the pilot bit to effect adjustment of the drilling angle. Furthermore, the drill rod can adopt a plurality of sections to be connected to form a hollow drill rod with an ultra-long distance, and the plurality of sections of drill rods are detachably connected and installed through automatic equipment for convenient installation and disassembly.
In some embodiments, for the condition of undetermined karst (or collapse body) in underground engineering, reasonable drilling paths can be designed in the current construction operation surface by using advanced geological forecast data, and meanwhile, grouting treatment is accurately realized on the undetermined karst (or collapse body) by using a high-strength hollow drill rod of a horizontal directional drill, so that guarantee is provided for the next construction. Aiming at the conditions of door closing collapse and karst (or collapse) in underground engineering, a horizontal directional drilling machine is utilized to drill through a life channel and grouting, the horizontal directional drilling machine has the characteristics of miniaturization, flexibility and quick response, meanwhile, the horizontal directional drilling machine has a certain drilling direction-changing capability, and can adapt to the actual conditions on site.
