Description

Technical Field

[0001] This specification relates to the technical field of drilling, and particularly to a construction system for rock anchor holes. Background Art

[0002] An anchor hole is a drilled hole constructed for laying anchor rods or cables when carrying out anchoring projects on rock and soil slopes, dangerous rocks, and building components. The function of the anchor hole is to fix the anchor rod or cable to increase the stability and tensile strength of the anchor pier. An anchor pier is an infrastructure for supporting and fixing structures, commonly found in projects such as bridges, tunnels, and docks.

[0032] Please refer to Figure 1。The embodiments of the present application provide a construction system for rock anchor holes, including: a first working area 1, a second working area 2, a first drilling rig 3, a second drilling rig 4, a sedimentation tank 7, a vibrating screen 10, a mud tank group 11, and two mud pumps 12.

[0033] Among them, the first working area 1 and the second working area 2 are distributed on both sides. The first drilling rig 3 is arranged in the first working area 1 and is used for drilling a first hole group 5. The first hole group 5 includes multiple columns, and the orifices in each column of the first hole group 5 are evenly arranged at intervals, and the orifices of adjacent two columns of the first hole group 5 are arranged staggeredly.

The sedimentation tank 7 is arranged between the first working area 1 and the second working area 2. The first hole group 5 is connected to the sedimentation tank 7 through a first mud flow channel 8, and the first mud flow channel 8 is used for discharging the construction sewage of the first hole group 5 to the sedimentation tank 7. The second hole group 6 is connected to the sedimentation tank 7 through a second mud flow channel 9, and the second mud flow channel 9 is used for discharging the construction sewage of the second hole group 6 to the sedimentation tank 7. The vibrating screen 10 and the mud tank group 11 are arranged between the first working area 1 and the second working area 2.

The mud tank group 11 is communicated with the two mud pumps 12, and the two mud pumps 12 are used for pumping the mud when the first drilling rig 3 and the second drilling rig 4 drill the first hole group 5 and the second hole group 6 into the mud tank group 11.

[0034] The rock anchor hole construction system provided by this embodiment can improve the construction efficiency by setting a first working area 1 and a second working area 2 on both sides, with a first drilling rig 3 for drilling the first hole group 5 in the first working area 1 and a second drilling rig 4 for drilling the second hole group 6 in the second working area 2, and the first drilling rig 3 and the second drilling rig 4 work simultaneously. Both the first hole group 5 and the second hole group 6 have multiple columns, and the orifice intervals within each column of the first hole group 5 and the second hole group 6 are evenly arranged. The orifices of adjacent two columns of the first hole group 5 are staggeredly arranged, and the orifices of adjacent two columns of the second hole group 6 are staggeredly arranged. The arrangement of the first hole group 5 and the second hole group 6 can make the positions of the drilled rock anchor holes meet the requirements to ensure the stability of the subsequent anchoring system. By setting a sedimentation tank 7, a vibrating screen 10, a mud pump 12 and a mud tank group 11, the sedimentation tank 7 can preliminarily precipitate rock debris, and the initially separated water enters the mud tank group 11 through the vibrating screen 10, so that the water can be recycled; the mud pump 12 can pump the mud when the first drilling rig 3 and the second drilling rig 4 drill the first hole group 5 and the second hole group 6 into the mud tank group 11, and the construction sewage of the first hole group 5 and the second hole group 6 is discharged to the sedimentation tank 7 through the first mud flow channel 8 and the second mud flow channel 9, which can ensure the smooth progress of the rock anchor hole construction.

[0035] In this embodiment, the first hole group 5 and the second hole group 6 are located in slightly weathered dacite and are arranged in a plum blossom shape, and the hole diameters have two specifications of 300 mm and 350 mm. The first hole group 5 includes 1 test drilling hole and 35 rock anchor holes, the first hole group 5 includes 7 columns, the distance between adjacent two columns is 1.5 m, and the orifice spacing within each column of the first hole group 5 is 1.6 m. The second hole group 6 includes 1 test drilling hole and 35 rock anchor holes, the second hole group 6 includes 7 columns, the distance between adjacent two columns is 1.5 m, and the orifice spacing within each column of the second hole group 6 is 1.6 m. The test drilling hole is used to check the standby cable, and the hole diameter is 350 mm. In addition, a drainage hole 15 with a hole diameter of 300 mm can also be drilled between the first hole group 5 and the second hole group 6.

[0036] Specifically, the angle between the hole channels of the first hole group 5 and the second hole group 6 and the horizontal plane is 37°, and the hole channels of each column are scattered at angles of 2.86°, 5.71°, and 8.53° respectively with the central column. The lengths of the hole channels of the first hole group 5 and the second hole group 6 are 33.8 m to 40.1 m, and the average length of the hole channels of the first hole group 5 and the second hole group 6 is 37.1 m, which can make the drilled rock anchor holes meet the requirements to ensure the stability of the subsequent anchoring system.

[0037] In this embodiment, the first mud flow channel 8 and the second mud flow channel 9 are formed by brickwork along the rock mass below the rock anchor hole, with a height of 1m and a width of 0.29m. The sedimentation tank 7 is mainly used to precipitate rock debris, and has a length, width and height of 2m, 6m and 1m respectively. The interior of the sedimentation tank 7 is bricked with a 0.5-meter-high water-turning wall. The sedimentation tank 7 initially precipitates rock debris, and the initially separated water passes through a submersible pump, passes through a vibrating screen 10, and enters a mud tank group 11 to recycle the water.

[0038] like Figure 1 As shown, in order to improve efficiency, the first working area 1 is provided with a first drilling tool box 13 on the side of the first drilling rig 3 away from the second working area 2, and the second working area 2 is provided with a second drilling tool box 14 on the side of the second drilling rig 4 away from the first working area 1, so as to facilitate the first drilling rig 3 and the second drilling rig 4 to replace the drilling tools in time.

[0039] Specifically, the coring drilling construction process is adopted on site, and a large amount of clean water circulation is required for cooling, so the first working area 1 and the second working area 2 are connected to a water source. The water source interface is less than 20m away from the construction working surface of the first hole group 5 and the second hole group 6. The water source is used to provide construction water, and the flow rate is not less than 5m³ / h.

[0040] In this embodiment, the rock anchor hole construction system also includes a secondary distribution box. The secondary distribution box is electrically connected to the first drilling rig 3, the second drilling rig 4, the vibrating screen 10, and the mud pump 12, and is used to provide construction electricity with a frequency of 50Hz, a voltage of 380V, and a maximum power of 800kW. The power interface of the secondary distribution box is less than 30m away from the construction working surface of the first hole group 5 and the second hole group 6. The secondary distribution box can reserve 16 sub-gates to provide construction electricity for rock anchor hole construction.

There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this specification, unless otherwise specified, the meaning of "plurality" is two or more.

[0042] Any numerical value recited herein includes all values from the lower value to the upper value incremented by one unit therebetween, provided that there is a separation of at least two units between any lower value and any higher value. For example, if a value for a component number or a process variable (such as temperature, pressure, time, etc.) is recited as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc. are also expressly recited in this specification. For values less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples of what is intended to be specifically recited, and all possible combinations of numerical values recited between the lowest value and the highest value are to be considered as being expressly recited in this specification in a similar manner.

[0043] Unless otherwise indicated, all ranges include the endpoints and all numbers therebetween. The term “about” or “approximate” used in connection with a range is applicable to both endpoints of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, including at least the recited endpoints.

[0044] All articles and references, including patent applications and publications, are incorporated herein by reference for various purposes. The term “consisting essentially of” describing a combination should include the identified elements, ingredients, components or steps as well as other elements, ingredients, components or steps that do not materially affect the basic novel characteristics of the combination. The use of the terms “comprising” or “including” to describe combinations of elements, ingredients, components or steps herein also contemplates embodiments consisting essentially of these elements, ingredients, components or steps. By using the term “may” herein, it is intended that any of the attributes described as “may” be included are optional.

[0045] A plurality of elements, ingredients, components or steps can be provided by a single integrated element, ingredient, component or step. Alternatively, a single integrated element, ingredient, component or step can be separated into discrete plural elements, ingredients, components or steps. The disclosure of the articles “a” or “an” used to describe elements, ingredients, components or steps does not preclude the presence of other elements, ingredients, components or steps.

[0046] It should be understood that the above description is for illustrative purposes and not for limitation. Upon reading the above description, many embodiments and many applications other than the provided examples will be apparent to those skilled in the art. Therefore, the scope of this teaching should not be determined with reference to the above description, but rather should be determined with reference to the appended claims and the full scope of equivalents to which those claims are entitled. For the sake of completeness, all articles and references, including patent applications and published disclosures, are incorporated herein by reference. The omission of any aspect of the subject matter disclosed herein from the foregoing claims is not intended to abandon such subject matter, nor should it be considered that the inventor has not considered such subject matter to be a part of the disclosed utility model subject matter.
