Description

Technical Field

[0001] The invention relates to the technical field of geological drilling, and more specifically, to a construction survey and sampling device. Background Art

[0002] Sampling for construction survey is an important part of the construction process, which involves sampling and testing of construction materials, geological conditions, etc. Through sampling, possible problems and hidden dangers in construction materials or geological conditions can be discovered, and timely measures can be taken to deal with them to ensure construction safety and project quality.

[0003] When investigating the geological conditions of the construction site, in order to find out the actual distribution of the underground soil layers at the construction site, it is necessary to drill and sample the geological soil layers. The usual practice is to use a drill rod to drill directly into the predetermined depth in the stratum, and output the soil samples of the corresponding soil layers while drilling the borehole. The drilled soil samples are then imported into different sample storage tubes for storage, and the marking information is done (in order to distinguish soil layers of different depths and different batches) to facilitate sampling, observation, analysis and transfer.

[0004] After the existing construction survey and drilling operations, the backfilling of soil relies on manual use of tools to push the soil into the hole. The backfilled soil does not correspond to the drilled soil, which is not only time-consuming and labor-intensive, but also increases the amount of manual labor. In addition, due to the mismatch between the backfilled soil and the soil at the drilling location, the different soil qualities of soil at different depths (the deep soil becomes loose when it is drilled out), and the influence of the diameter of the drilling hole (in order to reduce damage to the environment, the drilling hole is generally not very large), it is easy to form a blockage in the middle of the borehole, and the drilled soil cannot be completely backfilled (the remaining soil is discarded or accumulated in the surrounding environment of the borehole, affecting the surrounding environment); and as time goes by, the holes that are blocked during the backfilling process, the backfilled soil will gradually sink under the action of the soil's own gravity, resulting in secondary settlement, causing the landfill hole to reappear, posing a safety hazard.

An arc-shaped slide rail 28 is fixed on the top of the support base plate 3, an arc-shaped guide rail 29 coaxial with the arc-shaped slide rail 28 is installed on the side of the support base plate 3 close to the base 1 through bolts, and an arc-shaped slide groove 30 cooperating with the arc-shaped slide rail 28 and the arc-shaped guide rail 29 is installed at the bottom of the bearing plate 10.

[0053] A driving box 31 is installed on the top of the frame 2. A lifting screw 32 connected to the lifting frame 4 is vertically penetrated at the four corners of the driving box 31. A driven sprocket 33 is fixed to one end of the lifting screw 32 located inside the driving box 31. A transmission shaft is installed in the driving box 31 and located between two adjacent driven sprockets 33. A first sprocket 34 and a second sprocket 35 are installed on the transmission shaft from bottom to top. A driving motor 36 is installed in the driving box 31. A driving sprocket 37 is fixed to the output shaft end of the driving motor 36. The driving sprocket 37 is connected to the first sprocket 34 through a first transmission chain 38.

A tensioning wheel 40 meshing with the second transmission chain 39 is installed at the top of the driving box 31 and located between the driven sprocket 33 and the second sprocket 35.

[0054] The working principle of the geological and mineral exploration drilling equipment provided by the present invention is as follows:

[0055] Working principle: The driving structure in the driving box 31 drives the lifting screw 32 to rotate, so that the lifting frame 4 moves downward, so that the spiral drill rod 6 passes through the guide tube 22 and contacts the ground where the hole needs to be drilled, and then the drilling machine 5 is started to drive the spiral drill rod 6 to rotate, and the drilling operation begins (while drilling, the lifting frame 4 slowly moves downward to a certain depth to drill soil at different depths). The soil produced by the drilling is output upward along the guide tube 22 under the drive of the spiral drill rod 6 until it falls into the receiving hopper 7, and then is input into the sewage extrusion pipe 9 through the mud and water output pipe 8. After the sewage extrusion pipe 9 discharges part of the mud and water (discharge), the mud and water are discharged from the sewage extrusion pipe 9. The sludge storage cylinder 15 is used to remove a large amount of water mixed in the soil during drilling, which is convenient for later observation of the drilled soil) and then input into the sludge storage cylinder 15 (at this time, one end of the telescopic push rod 41 is pressed against the sludge storage cylinder 15, so that the open end of the sludge storage cylinder 15 is in contact with the open end of the sewage extrusion pipe 9). After a sufficient amount of soil is input (the telescopic push rod 41 releases the squeezing of the sludge storage cylinder 15), the sludge storage cylinder 15 filled with soil is removed, and the empty sludge storage cylinder 15 in the connecting bucket 13 automatically falls down, and then, one end of the telescopic push rod 41 is pressed against the sludge storage cylinder 15 again, and the soil is stored reciprocatingly in sequence.

[0056] The sludge storage cylinder 15 storing sample soil is stored in sequence according to the sampling depth. According to the different sampling depths, the soil in the sludge storage cylinder 15 is observed through the observation glass window 1507 opened on the outer surface of the cylinder 1501, and the corresponding soil sample is taken out through the opening at one end of the cylinder 1501 for testing.

[0057] After the drilling survey is completed, when the borehole needs to be backfilled, the second motor 27 drives the load-bearing plate 10 to rotate, so that the end of the discharge chute 12 is away from the connecting bucket 13 and close to the receiving bucket 7, and the electromagnetic suction cup 18 is controlled to absorb the sludge storage cylinder 15 filled with soil (when the electromagnetic suction cup 18 absorbs the sludge storage cylinder 15, the sludge storage cylinder 15 is connected to the external air pump), and the sludge storage cylinder 15 filled with soil is lifted by the joint action of the electromagnetic suction cup 18, the lifting column 16, and the first telescopic rod 17. The first telescopic rod 17 is extended, so that the vertically suspended sludge storage barrel 15 moves to the top of the guide pipe 22 (at this time, the lifting column 16 drives the first telescopic rod 17 to rise, and the second telescopic rod 20 drives the electromagnetic suction cup 18 to rotate around the telescopic end of the first telescopic rod 17, and the first telescopic rod 17 is extended synchronously, so that the sludge storage barrel 15 is vertically erected and kept coaxial with the guide pipe 22 as much as possible), and air is blown into the sludge storage barrel 15 through an external air pump, so that the sludge storage barrel 15 outputs the internal soil, thereby realizing the backfilling of the borehole reciprocatingly.

[0058] Embodiment 2: Based on the specific embodiment 1, the difference of this embodiment is that:

[0059] like Figure 1 , 4 As shown in 7-11, the sewage extrusion pipe 9 includes an inner frame pipe 901 connected to the mud and water output pipe 8 through bolts, and a plurality of filter press plates 902 are installed on the inner frame pipe 901. The filter press plates 902 are composed of a fixed frame with a mounting groove 903 and a filter cloth. The filter cloth is filled in the fixed frame to form a filter layer. The filter cloth is made of the same material as the plate and frame type sludge dewatering machine, which can effectively separate the mud from the mud and water. The inner frame pipe 901 is provided with a plurality of mounting grooves 903 that match the filter press plates 902. The outer sleeve of the frame pipe 901 is provided with an upper guide cover 904 and a lower guide cover 905 which are fixedly connected by bolts. A drainage groove 906 which is connected to the inner cavity of the lower guide cover 905 is installed on the outer circumferential surface of the lower guide cover 905. The output end of the drainage groove 906 is connected to a water receiving box 908 through a guide pipe 907. The water receiving box 908 is installed on the base 1. A water pump 909 is installed on the top of the water receiving box 908. A water pump 910 which is connected to the inner cavity of the water receiving box 908 is installed at the water inlet end of the water pump 909. The muddy water separated by the filter press plate 902 enters the drainage groove 906 on the lower guide cover 905, and flows into the water receiving box 908 through the guide pipe 907. The filtered muddy water entering the water receiving box 908 is then pumped out by the water pump 909 through the water pump pipe 910 for use during drilling, thereby reducing the waste of water resources and reducing the pollution to the surrounding environment of drilling.

[0060] Embodiment 3: Based on the specific embodiment 2, the difference of this embodiment is that:

[0061] like Figure 1 , 4 As shown in 16-18, the sludge storage cylinder 15 includes a cylinder 1501 that cooperates with the through hole 14, one end of the cylinder 1501 is open, and the other end of the cylinder 1501 is fixed with an annular adsorption seat 1502 that cooperates with the electromagnetic suction cup 18, and one end of the cylinder 1501 on which the annular adsorption seat 1502 is installed is fixed with an air pipe 1503 that penetrates the cylinder 1501. After the annular adsorption seat 1502 is adsorbed by the electromagnetic suction cup 18, the air pipe 1503 is connected to an external air pump, and the air pipe 1503 is connected to the external air pump. An air bag 1504 connected to the trachea 1503 is fixed at one end of the cylinder 1501, and a push plate 1505 matching the inner cavity of the cylinder 1501 is fixed at one end of the air bag 1504 away from the trachea 1503. A rubber seal ring 1506 is installed on the outer circumference of the open end of the cylinder 1501, and an observation glass window 1507 is provided on the outer circumference of the cylinder 1501. The rubber seal ring 1506 ensures the airtightness of the connection when connected with the inner frame tube 901. The state of the soil input into the cylinder 1501 is observed through the observation glass window 1507. When the cylinder 1501 is lifted and the internal soil needs to be discharged, the external air pump inputs air into the air bag 1504 through the trachea 1503, and the air bag 1504 expands and pushes the push plate 1505 to move. Under the action of the push plate 1505, the soil is pushed out of the cylinder 1501.

[0062] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
