Problems solved by technology

Reasonable configuration of construction parameters can improve construction efficiency and speed up construction progress. However, since there are few construction cases of underwater rock drilling and it is difficult to directly observe as a hidden project, the configuration of construction parameters lacks data support and is highly subjective.

Embodiment 1

[0100] like Figure 5 to Figure 9 As shown, the rock drilling rod includes a main body 1, a set of lifting lugs 11 are hinged on the top of the main body 1, a pair of cavities 12 are symmetrically arranged in the main body 1, and the bottoms of the two cavities 12 are communicated with each other through pipes; A piston 13 is slidably sealed and connected, and the piston 13 divides the cavity 12 into an upper cavity 14 and a lower cavity 15; the lower cavity 15 is filled with mercury; one side of the cavity 12 is provided with a rotating shaft 16, and one end of the rotating shaft 16 runs through The piston 13 is threadedly connected with the piston 13, and the other end of the rotating shaft 16 extends into the slot on the top of the cavity 12; the motor 17 is fixedly connected to the slot through the bracket, and the output shaft of the motor 17 is fixedly connected to a gear 18; the The rotating shaft 16 is fixedly connected with the No. 2 gear 19 at the corresponding posit...

Embodiment 2

[0108] like Figure 10 As shown, the lower end of the heat pipe 28 is filled with a sponge 43, and the sponge 43 is impregnated with alcohol; the lower end of the heat pipe 28 is provided with an elastic arc-shaped rod 44, and the trachea 27 is provided with a push rod 45, and the push rod 45 One end is in contact with the end of the sliding rod 26, and the other end is fixedly connected with the arc-shaped rod 44; when the sliding rod 26 slides up, the push rod 45 is pushed up, driving the arc-shaped rod 44 and the sponge 43 to slide in the heat pipe 28, and then continuously squeezed The alcohol in the sponge 43 is extracted and recovered, and the circulation and heat transfer efficiency of the alcohol in the heat pipe 28 is increased.

[0109]During operation, the present invention sets two symmetrical cavities 12, and drives the first gear 18 to rotate through the motor 17, thereby driving the rotating shaft 16 to push the piston 13 to slide, changing the volume of mercury...

Abstract

The invention belongs to the field of underwater rock drilling construction, and specifically relates to an on-site test method for underwater rock drilling construction parameters. S1. Drilling of rock layers in a construction area; Drilling, sampling and indoor geotechnical tests are used to measure the saturated uniaxial compressive strength of the construction rock; S2, test area selection; bit test; S3, design of the test plan; through the single factor test, the control variable method is used to test the lifting height of the rock drilling rod, the distance between the front and rear position of the rock drilling hammer, the left and right position distance of the rock drilling hammer, and the number of chisels; measure the construction efficiency , revealing the influence of a single rock drilling parameter on the rock breaking effect and the thickness of the reef.

Description

technical field [0001] The invention belongs to the field of underwater rock drilling construction, in particular to a field test method for underwater rock drilling construction parameters. Background technique [0002] Rock drilling technology is a common method for breaking rock mass in dredging projects. By raising the rock drilling rod to a certain height and then lowering it, it impacts the underwater rock mass to achieve the purpose of smooth reef cleaning. The rock drilling process has little impact on the surrounding construction environment, and has few construction restrictions. It can take into account the construction, waterway passage and environmental protection, showing great prospects and application value. With the domestic emphasis on environmental protection and the increase in navigation pressure, rock drilling technology has gained more and more opportunities as an alternative to underwater blasting technology. [0003] However, the rock drilling const...
