Document Type and Number:
WIPO Patent Application WO/2021/218252
Kind Code:
A1
Abstract:
Disclosed is tunnel pressure coring equipment having an automatic alarm function. The equipment comprises continuous guide pipe operation equipment and a corer (3). The continuous guide pipe operation equipment comprises a transfer device (2). The transfer device (2) comprises an injection head (1202) and a tunnel drill machine. The corer (3) comprises an inner pipe assembly and an outer pipe assembly. The outer pipe assembly is connected to the tunnel drill machine via a drill rod (4). The inner pipe assembly is connected to a continuous guide pipe (9). The injection head is used to lower/raise the continuous guide pipe (9). The inner pipe assembly and the outer pipe assembly are engaged and connected. The inner pipe assembly comprises an inner pipe component and a center component. The center component comprises a center rod (71). A top end of the center rod (71) is connected to the continuous guide pipe (9). The continuous guide pipe (9) and the center rod (71) are both hollow structures. A power cable is installed within the continuous guide pipe (9) and the center rod (71). A base surface apparatus supplies power and/or provides a signal to an electronic apparatus in the corer via the power cable. The coring equipment has superior operating performance, prevents core barrels from rotating during coring, ensures the purity of core samples, and enables easy detachment of the inner pipe assembly from the outer pipe assembly, thereby facilitating power cable delivery for signal reception and power supply.
