Embodiment 2

[0050] The difference between this embodiment and embodiment 1:

[0051] The material of the water collection bag is made of elastic material, such as bellows material. An elastic bag is arranged inside the water collection bag. The material of the elastic bag is rubber material. The setting of the water bag is convenient for storage and portability of the water collection bag. When in use, the water collection bag can be opened by stretching the water collection bag; otherwise, the volume of the water collection bag can be reduced.

Embodiment 3

[0053] The difference between this embodiment and embodiment 1:

[0054] The timer is a separate structure, not connected to the whole device.

Abstract

The invention discloses a device and method for measuring columnar water inflow quantity of a tunnel. The device comprises a water collection bag with a water receiving port; a weighing sensor which is used for measuring bearing water inflow weight in the water collection bag and installed in the water collection bag; and a timer for measuring water inflow time. The columnar water inflow quantity of the tunnel is calculated according to the formula that the columnar water inflow quantity=the water inflow weight measured by the weighing sensor / (water inflow density*water inflow time). Through arranging the weighing sensor and the timer, the columnar water inflow quantity of the tunnel can be measured accurately, and errors caused by human experience determination are prevented. The water collection bag is telescopic and elastically arranged, the volume of the water collection bag can be randomly changed, and the device is convenient to carry and operate. The device is simple in structure, easy to implement, relatively low in production cost, and good in practicability.

Description

technical field [0001] The invention relates to the field of tunnel engineering measurement, in particular to a device and method for measuring tunnel columnar water inflow. Background technique [0002] With the continuous development of my country's mineral resources and water energy and water resources, the center of gravity of underground engineering construction has gradually shifted to the western mountainous and karst areas with more complex topographic and geological conditions. During the construction of these projects, water inrush accidents often occur, seriously affecting the construction progress and construction safety. The measurement of water inflow plays an important role in disaster treatment, prediction and even scientific research. [0003] Columnar water gushing is an important part of fissure-type water gushing, which refers to the columnar jetting of water gushing from the wall of the tunnel due to the large amount of water. For the measurement of tu...
