[0001] The utility model relates to a construction engineering field reconnaissance technical field, concretely relates to a construction engineering field reconnaissance device. BACKGROUND

[0002] In construction engineering, field reconnaissance is a crucial link, and soil sampling is one of the important contents of field reconnaissance. Through sampling and analysis of soil, information such as the nature and composition of soil can be obtained, providing an important basis for the design and construction of construction engineering.

[0003] However, the existing soil sampling device for construction engineering field reconnaissance has some shortcomings. First, the sampling head of many sampling devices lacks effective protection measures, and is easily damaged by external factors during non-use or transportation, affecting its service life and sampling accuracy. Second, the structure design of part of the sampling cannula is unreasonable, which leads to inconvenient operation and cannot flexibly realize the sampling and recovery functions, bringing certain difficulties to the field reconnaissance carrying work.

[0032] Please refer to the instruction manual appendix. Figures 1-4 This utility model provides a site surveying device for building engineering:

[0033] I. Overall Structure of the Device

[0034] Relationship between sampling head and central receiving tube

[0035] The sampling head 1 of this construction site survey device can be completely retracted into the central storage tube 2. This design is mainly to protect the sampling head 1 from damage caused by external factors when the device is not in use or during transportation, and also to facilitate the overall storage and management of the device.

[0036] The sampling head 1 has a unique structure, consisting of a slider 11 and a sampling tube 12. The slider 11 is slidably engaged inside the central storage tube 2, and the sampling tube 12 is attached to the lower end of the slider 11. This combination structure allows the sampling tube 12 to move up and down within the central storage tube 2, thereby achieving the functions of sampling and retrieval while ensuring portability.

[0037] A locking bolt 4 is located at the front of the lower end of the central receiving tube 2. This locking bolt 4 is compatible with the locking hole 15 on the front side of the slider 11 and the extraction locking hole 16 on the front side of the bottom end of the sampling tube 12, and is used to realize the locking operation of the sampling tube 12 in different states of retrieval and extraction. When the sampling tube 12 is in the fully retracted state, the locking bolt 4 is inserted into the locking hole 15 of the slider 11 to fix the slider 11 and the sampling tube 12 in the central receiving tube 2 to prevent them from accidentally sliding out; when sampling is required, after the sampling tube 12 is pulled out to the appropriate position, the locking bolt 4 is inserted into the extraction locking hole 16 of the sampling tube 12, so that the sampling tube 12 is kept in the extended state for sampling.

[0038] Connection between the upper sleeve and the central receiving tube

[0039] The upper sleeve 3 is slidably fitted onto the top of the central receiving tube 2. A locking thread 32 is provided on the inner wall of the lower end of the upper sleeve 3, which is screwed onto the outer side of the top of the central receiving tube 2. This structural design allows the upper sleeve 3 to be stably connected to the central receiving tube 2 and to be rotated relative to it. This screw-on structure ensures that the upper sleeve 3 is stably connected to the top of the central receiving tube 2, extending the entire exploration and sampling device for easier sampling operations.

[0040] II. Special Design of Each Component

[0041] Sampling cannula guide structure

[0042] The sampling tube 12 is provided with guide protrusions 14 on both the left and right sides. Correspondingly, guide rails 22 are provided on the left and right side walls inside the central receiving tube 2. The guide protrusions 14 and guide rails 22 are adapted to each other, so as to ensure the accuracy of the sliding direction when the sampling tube 12 slides up and down along the central receiving tube 2, and avoid deviation. The existence of the guide structure makes the movement of the sampling tube 12 more stable, and ensures that its locking hole 15 and withdrawal locking hole 16 are always in the locking position of the locking bolt 4 after it slides up and down.

[0043] Slider operation structure

[0044] The central receiving tube 2 has vertically distributed strip-shaped actuating holes 21 on its back side, and the slider 11 has a lever 13 on its back side, which is distributed inside the strip-shaped actuating holes 21. This lever 13 allows for easy up-and-down sliding of the slider 11, thereby moving the sampling tube 12 up and down within the central receiving tube 2. The lever 13 design allows operators to easily control the insertion and retrieval of the sampling tube 12 without disassembling the device.

[0045] Locking structure of the upper sleeve

[0046] A retrieval locking hole 33, shaped like the number 7, is provided at the lower end of the upper sleeve 3. When the locking bolt 4 locks the upper sleeve 3, the nut of the locking bolt 4 can be engaged inside the retrieval locking hole 33, thereby ensuring that the upper sleeve 3 is in a stable locked state. The 7-shaped retrieval locking hole 33 is ingeniously designed. It can not only effectively hold the nut of the locking bolt 4 to prevent the upper sleeve 3 from slipping out during retrieval, but also allow for the extension of the upper sleeve 3 by rotating and pulling it upward when it is necessary to unlock it.

[0047] Sampling-related structures of sampling cannula

[0048] The bottom end of the sampling cannula 12 is designed with a beveled cut. This shape facilitates easier insertion into the sampled material when sampling soil or other building materials. The beveled cut acts like a sharp wedge, reducing resistance during insertion and making it easier for the sampling cannula 12 to penetrate the soil at the construction site.

[0049] The sampling tube 12 has several evenly distributed protrusions 17 inside. These protrusions 17 can better grasp the sampled material during the sampling process, preventing it from slipping out of the sampling tube 12 and ensuring the integrity of the sample. The presence of the protrusions 17 increases the friction between the inner wall of the sampling tube 12 and the sampled material. When the sampling tube 12 is inserted into the sampled material and pulled upwards, the protrusions 17 can firmly grasp the sampled material, allowing it to be carried out intact, avoiding partial material loss during the sampling process. This ensures the accuracy and reliability of the sampling and provides an effective sample for subsequent architectural engineering survey and analysis.

[0050] Hammering auxiliary structure of upper sleeve

[0051] A hammering pad 31 is provided at the top of the upper sleeve 3. When the sampling tube 12 needs to be inserted into hard construction soil, the hammering pad 31 can be struck with a hammer or other tools to transfer the downward force to the sampling tube 12, assisting the sampling tube 12 to be smoothly inserted into the sampled material. The hammering pad 31 ensures that the upper sleeve 3 can evenly bear the hammering force during the hammering process and effectively transfer it to the sampling tube 12. At the same time, the hammering pad 31 can also act as a buffer, preventing the hammer from directly hitting the upper sleeve 3 and causing damage, thus extending the service life of the device. In addition, the hammering pad 31 can be made of materials with a certain degree of elasticity and wear resistance, such as rubber or high-strength plastic, to better perform its function.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
