Description
Technical Field
[0001] The invention belongs to the field of building deviation correction, and particularly relates to a method for measuring the volume of a hole for forced landing and correcting collapse of a building. Background Art
[0002] Existing buildings have uneven settlement due to foundation design and construction reasons, as well as collapsible soil, natural disasters, improper use and maintenance, which leads to overall tilting of the building, affecting the normal use of the building and seriously threatening personal and property safety. Measures must be taken to stop the settlement, correct the deviation, and reinforce the building to eliminate safety hazards. The forced landing method is widely used in building tilt correction, with the advantages of mature technology and low cost. The forced landing method is to drill holes in the foundation soil on one side of the tilted building to take soil, so that the building on the side with smaller settlement will be forced to settle until it is balanced with the side with larger settlement. However, during the implementation process, the soil holes cannot guarantee that the soil holes will collapse completely. The degree of collapse is affected by factors such as the arrangement of the soil holes, the characteristics of the foundation soil, and the foundation form of the building. It is difficult to accurately obtain the amount of collapse of the soil holes, which brings difficulties to determining the parameters such as the diameter and number of subsequent soil holes, which is not conducive to controlling the amount of building tilt correction and increases the uncertainty of the tilt correction process. In the prior art, there is no method and structure for accurately measuring the volume of collapsed holes. Summary of the invention

[0019] The following will provide a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figure 1-7As shown, a method for measuring the volume of a hole for taking soil for forced landing and correcting the collapse of a building comprises the following steps: Step 1: excavating a soil taking working pit 3 in the foundation soil 2 on the side of the inclined building 1 with less settlement, and drilling at least one soil taking hole 4 in the working pit 3 in the direction of the inclined building 1; the soil taking hole 4 is an original hole 41 at the initial stage; Step 2: selecting at least one representative soil taking hole 4, in which a measuring device 5 is arranged; the measuring device 5 comprises a measuring container 51 and a bag 52 connected to the measuring container 51; a section of the original hole 41 for which the collapse amount needs to be measured is section B of the original hole 41, and the bag 52 is arranged in the entire section B of the original hole 41; Step 3: injecting liquid into the bag 52 until the collapse amount is measured. The shape of the bag 52 with liquid set inside corresponds to the shape of the original hole 41; Step 4: After setting the designed number of soil holes 4 in the working pit 3, the surrounding foundation soil 2 will produce a certain collapse deformation under the foundation pressure of the inclined building 1, and the original hole 41 will be compressed into a collapsed hole 42 after the collapse deformation; Step 5: After the original hole 41 is compressed and deformed, the volume of the collapsed hole 42 is smaller than that of the original hole 41, and the liquid in the bag 52 is compressed and squeezed into the measuring container 51. The increased volume of the liquid in the measuring container 51 is the collapse amount of the original hole 41B section; Step 6: The collapse amount of other soil holes 4 is inferred from the collapse amount of the soil hole 4 with the metering device 5, and the total collapse amount is calculated.
[0020] Among them, a representative soil hole 4 is selected as the soil hole 4 for placing the metering device 5. This representativeness is set according to needs. For example, there may be soil holes 4 of various lengths, inclination angles, diameters, different positions, and different settlement degrees in the working pit 3, and one or several of each type are selected as representatives, so as to infer the collapse amount of other soil holes 4 of the same type. The selection of representative soil holes 4 is determined according to actual needs and different working conditions. In step three, the shape of the sac 52 with liquid arranged inside corresponds to the shape of the original hole 41; here, the shape of the sac 52 and the original hole 41 are as close as possible, so as to ensure that the liquid squeezed out after collapse is the same as the collapse amount, and to ensure that the volume measurement process is as accurate as possible. There are many ways to connect the metering container 51 with the sac, which can be directly connected or indirectly connected. The sac 52 can be made of a material such as plastic that can hold liquid, and the shape of the object held will change when subjected to force or held. In addition, the liquid injected into the sac 52 in step three is preferably water, or other liquids. The soil hole 4 in the present invention is set obliquely downward, and the end is located below the building. The spacing between the soil holes 4, the inclination angles and sizes of the soil holes 4 are set as required. In the present invention, the purpose of forced landing of the tilted building 1 is achieved by the overall sinking of the foundation soil 2. In step six, after calculating the total collapse amount of this settlement, the soil volume for subsequent settlement is compared with the designed soil volume, which also provides a basis for the form and number of subsequent soil holes 4. The present invention measures the collapsed hole volume of the soil holes 4 for correcting the tilt of the building by the forced landing method, so that the control of the straightening rate of the tilted building 1 is more accurate, and potential safety hazards are eliminated. It is a safe, reliable, simple, intuitive, efficient and low-cost process for measuring the collapsed hole volume of the soil holes 4, and has significant economic and social benefits.
[0021] The metering container 51 is arranged outside the soil-boring hole 4, and the lower end of the metering container 51 is connected to the sac 52 through a connecting pipe 53; a water injection port is arranged at the upper end of the metering container 51; in step three, liquid is injected into the metering container 51, and the liquid then enters the sac 52; after the water injection is completed, there is liquid at the bottom of the metering container 51, the connecting pipe 53, and the sac 52. The metering container 51 can be arranged in the soil-boring pit or on the ground. The connecting pipe 53 can be a hard pipe or a soft pipe. After the water injection is completed, there is liquid at the bottom of the metering container 51, and after the original hole 41 collapses, the liquid level in the metering container 51 rises, and the volume reduction of the collapsed hole 42 is calculated according to the rising height of the liquid level. After the water injection is completed, the water injection port can be closed to form a closed metering device 5. Among them, the sac 52 of each soil-boring hole 4 can be connected to its own metering container 51. The bags of multiple soil-boring holes 4 may also be connected to the same measuring container 51. In this case, the increased liquid volume in the measuring container 51 is the collapse volume of the multiple soil-boring holes 4, which may be averaged.
[0022] The section of the original hole 41 that does not need to measure the collapse is section A of the original hole 41; a protective tube 6 is installed in section A of the original hole 41; the connecting tube 53 and the end of the bag 52 close to the connecting end are located in the protective tube 6. The protective tube 6 is provided to protect the connecting tube 53 and the end of the bag 52 in section A of the original hole 41 from being squeezed and deformed. It is ensured that the parts that are squeezed and deformed are all located in section B where the amount of soil taken needs to be measured, thereby ensuring the accuracy of the metering structure. Section B generally includes and is greater than the length of the original hole 41 that will collapse after settlement, ensuring the accuracy of the amount of soil taken. Section A is located in the length from the outlet of the original hole 41 to section B, that is, the remaining length outside section B is removed.
[0023] The measuring container 51 is a straight tube container, on which a scale for measuring is set.
[0024] The shape of the original hole 41 is circular. It can also be other shapes, determined according to needs. After the overall settlement work is completed, the building tilt correction is completed, the metering device 5 is taken out, and the working pit 3 is backfilled until the ground returns to its original appearance.
[0025] The present invention also provides a volume measuring device 5 for taking soil for forced landing and correcting collapse of a building, comprising a working pit 3 arranged in the foundation soil 2 on the side of the inclined building 1 with less settlement, at least one taking soil hole 4 being arranged in the working pit 3 in the direction of the inclined building 1; a bag 52 connected to a measuring container 51 outside the taking soil hole 4 being arranged in at least one taking soil hole 4; the bag 52 after being injected with liquid is fitted with section B of the taking soil hole 4 where the collapse amount needs to be measured.
[0026] The lower end of the metering container 51 is connected to the bag 52 through a connecting pipe 53; a protective pipe 6 is arranged in section A of the soil borrowing hole 4 where collapse measurement is not required, and the connecting pipe 53 is located in the part of the soil borrowing hole 4 and the end of the bag 52 close to the connecting end is located in the protective pipe 6.
[0027] The present invention installs a metering device 5 in a soil taking hole 4 for building foundation correction, and calculates the volume of the collapsed hole by the change of the liquid level in the metering container 51, so as to achieve the purpose of controlling the degree of building correction according to the amount of soil taken. The invention has the advantages of accurate measurement and easy realization, provides a basis for accurately controlling the amount of collapse, and has relatively significant economic and social benefits.
[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily, and as long as there is no contradiction in the combination of these technical features, they should be considered as the scope of this specification. Without departing from the overall concept of the present invention, the technical solution of the present invention and the equivalent replacement or change, as well as the changes and improvements made, should also be regarded as the protection scope of the present invention.
