Description

Technical Field

[0001] The invention relates to the field of auxiliary equipment for taking core samples of foundation piles, and in particular to a convenient-to-use sampling box for taking core samples of foundation piles. Background Art

[0002] In reality, in order to test the compressive strength, density and other performance indicators of concrete, the testers need to drill / extract cylindrical samples (i.e., core samples of the foundation piles) from the concrete foundation piles formed on site, pack the core samples in a sampling box and take them back to the laboratory for further testing. The existing sampling box is usually a rectangular parallelepiped with the box mouth facing upwards, and there are multiple core sample placement positions in the box. After the tester extracts a core sample from the foundation pile, the core sample is placed in any vacant core sample placement position of the sampling box, and then the length, diameter and other parameters of the placed core sample are measured and recorded (in order to distinguish the source information of each core sample), and the sampling of a core sample is completed. In the actual sampling process, the tester needs to extract multiple core samples from different foundation piles on site. The number of these core samples often exceeds the number of core sample placement positions of a single sampling box. In order to ensure that each extracted core sample can be placed in the core sample placement position of the sampling box, it is necessary to carry multiple sampling boxes in advance. Since the multiple sampling boxes are independent of each other, they are inconvenient to carry.

[0003] In order to ensure the accuracy of subsequent test results, the length of the extracted core sample is usually positively correlated with the height of the pile foundation; because the heights of different concrete piles are not exactly the same, the lengths of the extracted core samples are not exactly the same. Generally speaking, the lengths of multiple core samples extracted are not exactly the same, but the difference is not large, and they can all be placed in the core sample placement position of the sampling box; but if the length of a certain section of the extracted core sample is too long, it cannot be placed in the existing sampling box, and the only option is to customize an extended sampling box in advance, but the extended sampling box is larger in size and more inconvenient to carry, and because most core samples are of moderate length, they only occupy a small part of the space inside the sampling box after being placed in the extended sampling box, wasting the space inside the box. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an easy-to-use foundation pile core sampling box, which is convenient to carry and can accommodate core samples that are too long without wasting space in the box.

[0005] In order to solve the above problems, the present invention provides a convenient-to-use foundation pile core sampling box:

[0006] It comprises a plurality of identical sampling layers, each of which has two side walls, a left side wall and a right side wall, and a plurality of core sample receiving positions are arranged between the two side walls and are connected front to back;

[0007] When a plurality of sampling layers are spliced ​​and fixed together front to back, the corresponding core sample receiving positions are aligned and spliced ​​one by one, and a plurality of sampling layers can be stacked and fixed up and down to achieve storage.

[0008] Furthermore, the sampling layer is provided with a measuring piece that can be longitudinally moved forward and backward to measure the length of the core sample accommodated in the core sample accommodating position.

[0009] Furthermore: a slide groove running through from front to back is opened on the side wall of the sampling layer; the measuring piece includes a first slider and a second slider accommodated in the slide groove, and a clamping plate extending to the core sample accommodating position is provided on the upper part of each slider, and the two sliders move longitudinally forward and backward along the slide groove one after the other until their clamping plates clamp the core sample accommodated in the core sample accommodating position front and back to measure the length.

[0010] Furthermore: the first slider and the second slider have the same structure, and their upper parts extend laterally above the core sample accommodating position; the clamping plate is specifically movably mounted on the upper part of the slider and can slide laterally along the upper part of the slider.

[0011] Furthermore, when the two sampling layers are in a front-to-back splicing state, the slide grooves are aligned and spliced ​​with each other, and the two sliders can thus move longitudinally forward and backward along the spliced ​​slide grooves.

[0012] Furthermore, a length scale is provided along the slide groove, and the first slider and the second slider are always aligned with the length scale when they move longitudinally along the slide groove.

[0013] Furthermore, the sampling layer has a docking hole on its front side and a docking boss on its rear side. When the two sampling layers are spliced ​​front to back, the docking boss on the rear side of the front sampling layer sinks backward into the docking hole on the front side of the rear sampling layer.

[0014] Furthermore, the top surfaces of the two side walls of the sampling layer are provided with grooves and the bottom surfaces are provided with protrusions extending downwards. When the two sampling layers are stacked one on top of the other, the protrusions on the bottom surface of the side wall of the upper sampling layer are sunk downwards into the grooves on the top surface of the side wall of the lower sampling layer.

[0015] Beneficial effects: Under normal circumstances, the test personnel can directly put the extracted core sample of moderate length into the core sample storage position of the sampling layer for storage; if the length of the extracted core sample is too long, multiple sampling layers should be spliced ​​together front to back first, so that the corresponding core storage positions of the multiple sampling layers are aligned and connected one by one, and the core sample storage position of double length is obtained, which can accommodate the core sample of double length. Since the sampling layer of the sampling box of the present invention can lengthen the length of the core sample storage position by splicing, there is no need to pre-customize a larger extended version of the sampling box as in the background technology. It is only necessary to manually splice the core sample storage position of the appropriate length according to the actual length of the core sample. Therefore, it is not easy to waste space in the box, and the volume of the sampling box will not be large, which is convenient to carry. When it is necessary to carry it, the test personnel can stack multiple sampling layers up and down to achieve storage, so that these stacked sampling layers together form a whole, which is more convenient to carry.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with specific implementation methods.

[0028] The easy-to-use foundation pile core sampling box includes multiple sampling layers with the same structure. Take one of the sampling layers as an example. Figure 1 The sampling layer 1 has two side walls 11 and 12 on the left and right. The area between the two side walls 11 and 12 is partially concave, and four core sample receiving positions 13 are arranged on the left and right sides of the concave area. A slide groove 14 is opened on the top surface of the left side wall 11 of the sampling layer 1, and a first slider 21 and a second slider 22 are accommodated in the slide groove 14. The two sliders 21 and 22 are arranged one after the other and can move longitudinally forward and backward along the slide groove 14. Taking the first slider 21 as an example, its upper part extends horizontally to the right to the top of the second core sample receiving position 13 from left to right (combined with Figure 4 and Figure 5 ); the clamping plate 23 is movably mounted on the upper part of the first slider 21, extending toward the core sample receiving position 13 below, and sliding horizontally left and right along the upper part of the first slider 21 to move between the first and second core sample receiving positions 13 from left to right. The structure of the second slider 22 is the same as that of the first slider 21 (see Figure 3 ), which is also equipped with a clamping plate 23, which will not be described here. A length scale 3 is provided along the entire slide 14, which is located on the left side of the slide 14; the upper parts of the first slide 21 and the second slide 22 both extend to the left above the length scale 3 (see Figure 2 ), during the longitudinal movement of the two sliders 21 and 22 along the slide groove 14, their upper parts can always be aligned with the length scale 3.

[0029] After the test personnel extract the first core sample of appropriate length from the concrete foundation pile, the core sample 4 can be directly placed in the first core sample receiving position 13 from left to right of the sampling layer 1. Figure 5As shown, the first slider 21 and the second slider 22 are moved longitudinally forward and backward along the slide groove 14 to the front and rear sides of the core sample 4, and then the clamping plates 23 on the two sliders 21 and 22 are slid horizontally left and right along the upper parts of the respective sliders 21 and 22 to the first core sample accommodation position 13 from left to right. Then, the two sliders 21 and 22 are moved longitudinally forward and backward along the slide groove 14 one after the other until the clamping plates 23 on the two sliders 21 and 22 clamp the core sample 4 from front to back. At this time, the inspector can obtain the length dimension of the core sample 4 by calculating the value of the length scale 3 between the two sliders 21 and 22. Afterwards, if the inspector extracts a second core sample of appropriate length from the concrete foundation pile (not shown in the figure), the core sample can be placed in the second core sample accommodation position 13 from left to right of the sampling layer 1, and the two sliders 21, 22 and their clamping plates 23 are adjusted as above to measure the length of the second core sample, which will not be repeated here.

[0030] See Figure 1 , Figure 3 and Figure 5 The right side wall 12 of the sampling layer 1 is also provided with a chute 14 and a length scale 3, a first slider 21, a second slider 22, and a clamping plate 23 mounted on the two sliders 21, 22. The chute 14, the length scale 3, the two sliders 21, 22, and the two clamping plates 23 on the right are the same as those on the left, and are symmetrical. The only difference is that the two sliders 21, 22 and the clamping plates 23 on the right can measure the length of the core samples in the third and fourth core sample receiving positions 13 from left to right. The first slider 21, the second slider 22, and the clamping plates 23 mounted thereon together constitute a measuring member for measuring the length of the core sample received in the core sample receiving position 13. In other embodiments, the slide groove 14, the length scale 3, the two sliders 21, 22 and the two clamps 23 may be provided only on one of the side walls of the sampling layer 1. Accordingly, the upper portion of the sliders 21, 22 needs to be changed to laterally span above the four core sample receiving positions 13, so that the clamps 23 installed on the sliders can slide laterally left and right along the upper portion of the sliders 21, 22 to the four core sample receiving positions 13.

[0031] If the length of the core sample extracted from the concrete foundation pile by the inspector is too long (not shown in the figure), the core sample cannot be directly placed into a single sampling layer 1. It is necessary to first splice the two sampling layers 1 together front and back. Figure 3 The left side of the sampling layer 1 has a first docking protrusion 151 extending forward and a first docking hole 161 on the right side; Figure 5The left side of the sample layer 1 has a second docking hole 162, and the right side partially has a second docking boss 152 extending backward. The inspector aligns the two sampling layers 1 front and back, so that the first docking boss 151 on the front side of the sampling layer 1 at the rear is sunk forward into the second docking hole 162 on the rear side of the sampling layer 1 at the front, and the second docking boss 152 on the rear side of the sampling layer 1 at the front is sunk backward into the first docking hole 161 on the front side of the sampling layer 1 at the rear. The two sampling layers 1 are aligned as shown in FIG. Figure 6 As shown, the core sample receiving positions 13 of the two sampling layers 1 are detachably spliced ​​and fixed together, and the corresponding core sample receiving positions 13 are aligned and spliced ​​one by one to obtain four core sample receiving positions 13 of double length. In this way, the test personnel can put the core sample that is too long into the core sample receiving position 13 of double length for storage. Figure 6 and Figure 7 When the two sampling layers 1 are spliced ​​together front and back, their corresponding length scales 3 are aligned and spliced ​​to form a double-length length scale 3, and their corresponding chutes 14 are aligned and spliced ​​to form a double-length chutes 14. The first slider 21 and the second slider 22 in the chutes 14 can thus be longitudinally moved forward and backward along the spliced ​​double-length chutes 14, so as to measure the length of the core sample that is too long and is accommodated in the double-length core sample accommodation position 13. The sampling box of the present invention has a sampling layer 1 that can lengthen the length of the core sample accommodation position 13 by splicing. There is no need to pre-customize a larger extended version of the sampling box as in the background art. It is only necessary to manually splice the core sample accommodation position 13 of the appropriate length according to the actual length of the core sample. Therefore, it is not easy to waste space in the box, and the volume of the sampling box will not be large, which is convenient to carry. In other embodiments, the number of sampling layers 1 spliced ​​together front and back can be more than two.

[0032] See Figure 1 The top surface of the left side wall 11 of the sampling layer 1 is provided with three grooves 17 arranged in a front-to-back spacing, and the bottom surface is provided with three protrusions 18 arranged in a front-to-back spacing extending downward (see Figure 8 ), the three protrusions 18 and the three grooves 17 are aligned one by one; the right side wall 12 of the sampling layer 1 has three grooves 17 and three protrusions 18 (see Figure 8 ), the right convex block 18 is symmetrical with the left convex block 18, and the right concave groove 17 is also symmetrical with the left concave groove 17. When the sampling box needs to be carried, the inspector can align the two sampling layers 1 up and down, so that the six convex blocks 18 on the bottom surface of the upper sampling layer 1 are sunk into the six concave grooves 17 on the top surface of the lower sampling layer 1 one by one, and the two sampling layers 1 are thus stacked and fixed together in a detachable manner to achieve storage, such as Fig. 9 As shown, these stacked sampling layers 1 together form a whole, which is more convenient to carry. In other embodiments, the number of the sampling layers 1 stacked up and down can be more than two.

[0033] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
