The current seismic acquisition equipment body coupling embedding means is commonly artificial pit digging embedding and artificial pit knocking and beating embedding by using a mould. When the artificial pit is buried, the soil around the earthquake acquisition equipment is loosened, but the excavated pit is often not vertical, and the requirements of flatness, stability, straightness and compactness cannot be met, so that the coupling degree is poor. When the mould is used for manually knocking the striking pit for embedding, the timeliness is poor, and the safety accident of the hammer striking hand is easy to cause. Therefore, the conventional manual tools are used for the seismic acquisition equipment embedded tools for seismic exploration at present, and cannot meet the acquisition requirements of high quality and diversity at present for various earth surface conditions such as humus soil, raw soil, excavated soil, rammed soil, mudstone, sandstone, limestone and the like.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Referring to fig. 1-4, fig. 1-4 illustrate an exemplary dedicated embedment tool in accordance with some embodiments of the present disclosure, respectively, wherein fig. 1 illustrates a first embodiment; FIG. 2 illustrates a second embodiment; FIG. 3 illustrates a third embodiment; fig. 4 shows a fourth embodiment.

As shown in fig. 1-4, the utility model provides a special embedded tool for multi-surface seismic acquisition equipment, which comprises a drill rod 1, wherein one end of the drill rod 1 comprises a connector 2 for being configured to an output end of an electric hammer, and the other end of the drill rod comprises a drill bit 3; the peripheral wall of the drill rod 1 is provided with a coring pressure release structure, and the coring pressure release structure is used for assisting in drilling a stratum in the process of drilling the drill bit 3 and releasing pressure accumulated in the process of drilling the stratum.

Specifically, the electric hammer output end can be configured on any electric hammer capable of playing a drilling function, such as a lithium battery electric hammer and a hydraulic electric hammer. The electric hammer is usually provided with a chuck clamped with the connector 2, after the connector 2 is clamped with the chuck, when the electric hammer works, rotation and impact force can be generated through an internal mechanical device, and the output power is transmitted to the connector 2, so that the connector 2 drives the drill rod 1 and the drill bit 3 to rotate and perform impact motion in a preset torque and direction, or the drill rod 1 and the drill bit 3 do linear impact motion in a preset torque, so that the drill bit 3 is driven to continuously rotate to impact or perform drilling operation in a linear impact stratum, and seismic acquisition equipment can be embedded after drilling is completed. The earthquake acquisition equipment can be detectors, node instruments, large lines and the like.

In some embodiments, the connector 2 may be a square handle four-pit adapter, and the chuck may be an SDS quick chuck, so as to realize quick connection between the connector 2 and the chuck, and ensure that no torque is lost.

Therefore, the electric hammer drives the drill bit 3 to perform work, so that mechanized punching is realized, the energy consumption is low, the continuous work can be performed for 8-10 hours, the body coupling embedding of 60-80 times of earthquake acquisition equipment is completed, the labor intensity is reduced, the safety risk is reduced, and the embedding efficiency is 30-35% higher than that of the traditional earthquake acquisition equipment.

It should be noted that different strata have different physical properties and characteristics, such as different density, strength, core material type, etc., different strata need to select different embedding tools to achieve good body coupling effect, while the drill bit 3 adopted by the traditional tool has single type and single function, can not be embedded in a pit at one time on various stratum structures, and has the difficulty of embedding detectors on different ground surfaces.

The coring pressure-releasing structure is arranged on the drill rod 1, and can drill core materials along with the drill bit 3 in the process of drilling holes when the drill bit 3 drills down, and the core materials can be components forming stratum. The coring pressure release structure is matched with the drill bit 3, so that holes suitable for different earthquake acquisition equipment can be drilled, and a good body coupling effect is achieved; because the drill bit 3 is downwards introduced into the soil layer or the rock layer, soil or rock can be continuously accumulated to form higher hole wall friction resistance and hole internal pressure, and the hole internal pressure and hole wall friction resistance can be reduced due to the characteristic of the coring pressure release structure, so that the efficiency and accuracy of drilling are improved, the equipment loss is reduced, the data safety is ensured, and the burying requirements of high efficiency and high quality are met.

It will be appreciated that depending on the type of formation, the core material from which the coring pressure relief structure is drilled is different, and when the formation being drilled is of the earth type, the core material from which it is drilled is soil; likewise, when the formation being drilled is of the lithology type, the core material it is drilling is rock.

More specifically, coring pressure relief structures may be incorporated with the drill bit 3 when multi-surface pit formation is performed. Wherein the formation comprises a soil type and a lithology type; the drill bit 3 is a cone drill bit configured to drill the earth-type formation; alternatively, the drill bit 3 is a twist drill configured to drill the lithology type of formation.

In this embodiment, the soil type may include humus soil, raw soil, excavated soil, compacted soil, etc., and the lithology type may include mudstone, sandstone, limestone, etc. The drill bit 3 can be selected according to different rock or soil properties, a smooth pointed cone drill bit 3 can be used when drilling soil, as the soil is usually loose and relatively easy to penetrate, the pointed shape of the cone drill bit can help reduce the resistance and friction of the soil, so that the drill bit 3 can penetrate the soil more easily; while drilling for lithology, twist drills may be used where the rock is harder than the soil and the twist drills may generate a greater cutting force to cut and remove the rock.

It will be appreciated that different earth surfaces have different formations, and that humus, raw earth, excavated earth, compacted earth, mudstones, sandstones, limestone etc. form part of the different earth surfaces, thereby forming the formations of the earth surfaces. Therefore, the selection of the drill bit 3 and the coring pressure relief structure can be determined according to the soil property type and the lithology type of the stratum, and the body coupling embedding tool suitable for different surface/stratum embedding conditions can be obtained. For example, the embedment tool of the present utility model may be applied to at least mountain, hilly, plain, etc. surfaces, and is particularly applicable to various strata such as humus soil, raw soil, excavated soil, compacted soil, mudstone, sandstone, limestone, etc. under different surfaces.
