Problems solved by technology

[0008] However, there are still deficiencies in the existing technology, mainly because of complex geological conditions, it is necessary to implement advanced geological prediction holes. Due to the limitation of the working space in small-section tunnels, not only the cost of special drilling equipment for advanced geological prediction holes is high, but also the advanced geological prediction The hole drilling operation and the tunneling drilling operation cannot be carried out at the same time, and the construction progress is limited

Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] Such as figure 1 and figure 2 shown, where figure 1 For the prior art air retreat drilling hole layout diagram, in figure 1 In the middle, it is necessary to drill the central cut hole 14 at the center of the face, and arrange empty holes 15 along the periphery of the central cut hole 14. The empty holes 15 are not filled with medicine, and the peripheral holes 17 and auxiliary holes 18 are arranged at the same time. The auxiliary holes 18 are used a...

Abstract

The invention discloses a hydraulic tunnel drilling trolley excavation construction method and device. According to the method, a simple down-the-hole drill trolley combining a down-the-hole drill and a vehicle is used for drilling advanced geological forecast holes, and the advanced geological forecast holes are used as central cut holes. The device comprises the vehicle and the down-the-hole drill installed at the position of a container of the vehicle, and the down-the-hole drill is connected to the vehicle through a drilling machine platform; the drilling machine platform is provided with a supporting base used for supporting and controlling the drilling direction of a drill rod of the down-the-hole drill; and the down-the-hole drill is connected with the drilling machine platform through a connecting plate and a fastening bolt. The tunnel drilling trolley (the simple down-the-hole drill trolley) combining the down-the-hole drill and the vehicle is used for drilling the advanced geological forecast holes, the problem of complex tunnel geological conditions for advanced detection is solved, the advanced geological forecast holes are used as the central cut holes, drilling and chemical use of the cut holes are reduced, and the tunnel single-wheel circulation footage length is increased.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, and in particular relates to an excavation construction method and device for a hydraulic tunnel drilling trolley. Background technique [0002] Hydraulic tunnels are common hydraulic structures. In the past, manual wind drills and dobby drills were often used for drilling operations. The relevant existing technologies mainly include: [0003] The invention patent CN110080792A of Northwest Survey and Design Research Institute Co., Ltd. of China Power Construction Group discloses a tunnel excavation method based on micro TBM equipment, including the first step of detecting the uniaxial compressive strength of the rock, and the second step of selecting the drilling location , select the drilling location according to the uniaxial compressive strength of the rock; the third step is to drill the hole, install the automatic slag discharge machine and the TBM roadheader, alig...
