Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0050] Soft soil is characterized by high water content, low strength, large compressibility and poor water permeability. Due to the large settlement and significant rheological properties of soft soil foundations, cement mixing piles are often used to reinforce soft soil foundations during construction in soft soil areas to improve the bearing capacity of soft soil foundations and reduce foundation settlement deformation. The construction of cement mixing piles not only has low cost and high environmental protection, but also has a relatively short construction period and little disturbance to the original soil. The technology of cement mixing piles has been widely used in the reinforcement of soft soil foundations. Restricted by the current construction technology level of cement mixing piles, the judgment of the integrity of cement mixing pile shafts in domestic codes is basically in the qualitative stage. With the research and development of new curing materials for mixing piles and the improvement of mixing equipment, the pile-forming quality has been significantly improved, and it is very necessary to propose a set of methods for quantitatively evaluating the integrity of cement mixing pile shafts.

[0051] At present, the Rock Quality Designation (RQD) is generally used at home and abroad to evaluate the quality of rock masses (rocks). RQD is a quantitative parameter that basically reflects the integrity of engineering rock masses and can be used for reference in the quantitative evaluation of the integrity of cement mixing pile shafts. This patent can quantitatively evaluate the integrity of mixing pile shafts, effectively promote the development of mixing pile technology, and provide an important reference for the inspection and evaluation of mixing piles.

[0052] Figure 1 The flowchart of the quantitative evaluation method for the integrity of the cement mixing pile provided by the embodiment of the present application Figure 2 The detailed flowchart of the quantitative evaluation method for the integrity of the cement mixing pile provided by the embodiment of the present application, as Figure 1 and Figure 2 shown, the present application discloses that the quantitative evaluation method for the integrity of the cement mixing pile includes:

[0053] S101. Core sampling is carried out on the cement mixing pile to obtain the core sample of the cement mixing pile.

[0054] S102. The cumulative length of the first core samples with a length greater than or equal to the first length in the core sample of the cement mixing pile is counted, and the cumulative length of the long columnar core samples in the core sample of the cement mixing pile is counted, where the length of the long columnar core sample is greater than or equal to the second length.

[0055] S103. Calculate the rock quality designation (RQD) and the proportion of long columnar core samples of the cement mixing pile according to the cumulative lengths of the first core samples and the long columnar core samples.

[0056] In step S103, the rock quality designation (RQD) of the cement mixing pile is a quantitative parameter that basically reflects the integrity of the engineering rock mass and can be used for reference in the quantitative evaluation of the integrity of the cement mixing pile body. In this embodiment, the rock quality designation (RQD) of the cement mixing pile is calculated according to the cumulative lengths of the first core samples and the long columnar core samples, and the calculation formula includes:

[0057]

[0058] where RQD is the rock quality designation of the cement mixing pile, a is the cumulative length of the first core samples, and c is the total core drilling footage when core sampling is carried out on the cement mixing pile.

[0059] In this embodiment, the second length is greater than or equal to three times the length of the core sample of the cement mixing pile. The length ratio of the second length being greater than or equal to three times the length of the core sample of the cement mixing pile has been tested and verified, and it can detect with relatively high accuracy with fewer samples.

[0060] S104. Classify the integrity of the mixing pile body into at least four categories according to the rock quality designation of the core sample of the cement mixing pile and the proportion of long columnar core samples.

[0061] After calculating the rock quality designation (RQD) of the cement mixing pile, the cement mixing pile is classified into at least four categories according to the rock quality designation of the cement mixing pile, including:

[0062] When RQD≥75%, the cement mixing pile is classified as a Class I pile;

[0063] When 75% > RQD ≥ 50%, classify the cement mixing pile as Class II pile;

[0064] When 50% > RQD ≥ 25%, classify the cement mixing pile as Class III pile;

[0065] When RQD < 25%, classify the cement mixing pile as Class IV pile.

[0066] Among them, the basic quality of the rock corresponding to the Class I pile of the cement mixing pile is intact, the basic quality of the rock corresponding to the Class II pile of the cement mixing pile is relatively intact, the basic quality of the rock corresponding to the Class III pile of the cement mixing pile is moderately intact, and the basic quality of the rock corresponding to the Class IV pile of the cement mixing pile is poorly intact. By using the RQD index of the basic quality of the rock of the cement mixing pile, the integrity index of the basic quality of the rock of the cement mixing pile is divided into four categories, which can facilitate the distinction of cement mixing piles with different integrity levels and facilitate construction workers to quickly select cement mixing piles with different integrity levels during the construction process.

[0067] After calculating the RQD index of the basic quality of the rock of the cement mixing pile and dividing the integrity of the cement mixing pile into four categories, the method further includes calculating the k value of the cement mixing pile. Specifically: calculate the ratio of the cumulative length of the long cylindrical core sample to the cumulative length of the first core sample; divide the Class I, Class II, and Class III piles of the cement mixing pile into two subcategories according to the ratio of the cumulative length of the long cylindrical core sample to the cumulative length of the first core sample.

[0068] Correspondingly, this application divides the Class I, Class II, and Class III piles of the cement mixing pile into two subcategories according to the ratio of the cumulative length of the long cylindrical core sample to the cumulative length of the first core sample. It includes: when the cement mixing pile is a Class I to Class III pile, classify the cement mixing pile according to the ratio k of the cumulative length of the long cylindrical core sample to the cumulative length of the first core sample: when k ≥ 50%, the pile integrity is classified as subcategory a, when k < 50%, the pile integrity is classified as subcategory b; the calculation formula for the ratio k of the cumulative length of the long cylindrical core sample to the cumulative length of the first core sample includes:

[0069]

[0070] Among them, k is the ratio of the cumulative length of the long cylindrical core sample to the cumulative length of the first core sample, b is the cumulative length of the long cylindrical core sample, and a is the cumulative length of the first core sample. That is, when it is determined to be a Class I to Class III pile, it can be divided into two subcategories a and b according to the size of k: when k ≥ 50%, the pile integrity is subcategory a, when k < 50%, the pile integrity is subcategory b.

[0071] It should be noted that when the pile integrity is determined to be subclass a through this embodiment, it is determined that the core sample of the cement mixing pile has good integrity, that is, the core sample of the cement mixing pile is long columnar. When the pile integrity is subclass b, it is determined that the core sample of the cement mixing pile has poor integrity, that is, the core sample of the cement mixing pile is short columnar.

[0072] Specifically, the quantitative evaluation method for the pile integrity of the cement mixing pile in the embodiment of the present invention will be described in detail with specific embodiments below.

[0073] When using cement mixing piles to reinforce soft soil foundations, four cement mixing piles are selected. The pile length of each cement mixing pile is 25m, and the numbers are 1#, 2#, 3# and 4# respectively.

[0074] The double-tube single-acting sampler is used on-site to drill and take core samples, and its size and shape are inspected. The on-site core sampling results are as Figure 1 and Figure 4 shown. The cumulative length of the core samples of each pile with a length greater than or equal to 10cm is statistically calculated, and the rock quality designation RQD of the cement mixing pile is calculated.

[0075]

[0076] Calculate the ratio k of the cumulative length of the long columnar core samples (length ≥ 3d) in the core samples taken to the cumulative length of the core samples with a length greater than or equal to 10cm:

[0077]

[0078] In this embodiment, the total core drilling footage is 25m of the pile length, and the diameter of the core sample is 10cm. The summary table of the cumulative length of the core samples at all levels of the cement mixing pile is shown in Table 1:

[0079] Table 1 Summary table of the cumulative length of the core samples at all levels of the cement mixing pile

[0080]

[0081] For pile 1, the cumulative length of the core samples with a length greater than or equal to 10cm in the core samples taken is 1938cm, the RQD value is 77.52%, and the cumulative length of the long columnar core samples (length ≥ 30cm) is 852cm. The k value is 34.08% < 50%, so the pile integrity of pile 1 is complete subclass b, class Ⅰ b pile.

[0082] For pile 2, the cumulative length of the core samples with a length greater than or equal to 10cm in the core samples taken is 2276cm, the RQD value is 91.04%, and the cumulative length of the long columnar core samples (length ≥ 30cm) is 1383cm. The k value is 55.32% ≥ 50%, so the pile integrity of pile 2 is complete subclass a, class Ⅰ a pile.

[0083] The cumulative length of core samples with a length greater than or equal to 10 cm in the core sample of pile No. 3 is 2340 cm, the RQD value is 93.60%, the cumulative length of long columnar core samples (length ≥ 30 cm) is 1781 cm, and the k value is 76.11% ≥ 50%. Therefore, the pile integrity of pile No. 3 is complete class a, type Ⅰ a pile.

[0084] The cumulative length of core samples with a length greater than or equal to 10 cm in the core sample of pile No. 4 is 2005 cm, the RQD value is 80.20%, the cumulative length of long columnar core samples (length ≥ 30 cm) is 1100 cm, and the k value is 54.86% ≥ 50%. Therefore, the pile integrity of pile No. 4 is medium complete class a, type Ⅰ a pile. The pile integrity evaluation of piles No. 1 to 4 is shown in Table 2.

[0085] Table 2 Pile Integrity Evaluation Table of Piles No. 1 to 4

[0086]

[0087] It can be seen that through the quantitative evaluation method for the pile integrity of the cement mixing pile proposed in this application, the integrity of the cement mixing piles No. 1 to 4 can be evaluated, and at the same time, the cement mixing piles No. 1 to 4 are divided into type Ⅰ a and type Ⅰ b two categories, and the classification and evaluation basis include the RQD and k values.
