Dust-reduction spraying device for tunnel construction

Abstract

The invention provides a dust-reduction spraying device for tunnel construction. The dust-reduction spraying device comprises a base and is characterized in that a water tank is fixedly mounted on oneside of the top of the base, connecting blocks are welded to two sides of the inner cavity of the water tank, a first filter screen is arranged between the two connecting blocks, the bottom of the first filter screen contacts with the tops of the connecting blocks, clamp blocks are welded to two sides of the bottom of the first filter screen, one sides of the clamp blocks are clamped with the slots of the connecting blocks, a second filter screen is fixedly mounted at the top of the first filter screen, a sealing plate is hinged to one side of the top of the water tank through hinges, one side of the sealing plate is provided with a locking mechanism, a water outlet in one side of the water tank is fixedly connected with a water pump through a pipeline, and an atomizing mechanism is fixedly mounted on one side of the water pump through a pipeline. The dust-reduction spraying device has the advantages that impurities in water can be filtered through the first filter screen and the second filter screen, so that the device can use water from rivers nearly without causing blocking, and the adaptability of the spraying device is increased.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a dust suppression spray device for tunnel construction. Background technique [0002] With the progress of society, the state and enterprises pay more and more attention to occupational health. It is an inevitable requirement to create a good working environment for construction workers. Due to the narrow working surface and poor ventilation conditions of tunnel construction, the The dust and toxic and harmful gases are not easy to spread, which has a serious impact on the health of construction workers. It is also the hardest hit area for occupational diseases such as pneumoconiosis and acute and chronic poisoning of harmful gases. [0003] Tunnel construction is a complicated process, and its environmental pollution is also great. There are many tunnel construction surfaces and a large amount of construction dust. A large amount of dust will be generated during con...

[0003] Tunnel construction is a complicated process, and its environmental pollution is also great. There are many tunnel construction surfaces and a large amount of construction dust. A large amount of dust will be generated during construction blasting. The dust suppression effect is directly related to the construction site. It will seriously endanger the health of production personnel and affect the construction safety and production progress; so people later designed a dust suppression device to remove the dust, but the design of the traditional dust suppression device is relatively simple, resulting in a single function and adapting to Sex is not strong
