Abstract
Description
Technical Field
[0001] The invention relates to the technical field of vortex well construction, and in particular to a device for measuring the levelness of a vortex well barrel wall during a caisson process and a construction method. Background Art
[0002] In the field of metallurgical construction, the vortex well is an important building, which is indispensable as a public auxiliary water system for steel rolling and steelmaking. The vortex well is generally a circular reinforced concrete structure with a large diameter (18~32 meters), a thick wall (between 1~1.5 meters), and a deep burial (20~35 meters). It is the focus and difficulty in construction. Common construction methods include large excavation, reverse construction, caisson construction and other main methods. Among them, the caisson construction method is more common. Specifically, the soil below the blade foot at the bottom of the cylinder wall is excavated and hollowed out. When the deadweight of the caisson is greater than the friction between the caisson and the soil and the reaction force of the base blade foot, it can sink. During the sinking process, sinking difficulties, sudden sinking, tilting and other phenomena often occur. The above situations will cause deviations in the horizontality of the cylinder wall, and then measures need to be taken to continuously correct the deviation to ensure its verticality. The caisson process is actually a process of continuous correction. When the wall of the cylinder is tilted, the horizontality will inevitably deviate. The verticality is often measured by hanging a plumb line, while the horizontality is often measured by a level and a ruler. The caisson process needs to be monitored at least twice a day and corrected in time. As the sinking depth of the caisson increases, the difficulty of detecting the verticality of the caisson body is also increasing, and it is becoming increasingly difficult to choose a location for setting up the instrument.
[0003] Patent CN116026291A discloses a method for detecting and controlling the verticality of a caisson. By setting a verticality detection device, real-time detection of the verticality data of the caisson can be achieved, which can quickly increase the speed of caisson construction while ensuring the quality of caisson construction. However, the verticality detection device used in this method is relatively expensive.
[0004] In view of this situation, a device and a construction method for measuring the levelness of the swirl shaft wall during the caisson caisson process are invented to enable dynamic monitoring at any time, and the construction is convenient and efficient. Summary of the invention
[0005] In order to solve the above technical problems, the present invention provides a device and construction method for measuring the horizontality of the swirl well wall during the caisson process. The horizontality of the wall can be monitored at any time by the numerical difference between the liquid level of the level gauge and the scale. This construction method does not require the use of measuring instruments and can accurately determine the specific numerical value of the deviation at any time, which is convenient and quick.
[0006] To achieve this technical purpose, the present invention adopts the following scheme: In the first aspect, the present invention provides a device for measuring the horizontality of a swirl wellbore wall during a caisson sinking process, comprising a swirl wellbore wall, wherein a plurality of horizontal reference lines of the same height are evenly arranged on the wall at the bottom of the swirl wellbore wall, a scale reference line is arranged upward from the horizontal reference line, the scale reference line and the horizontal reference line are located at the same vertical position, each scale reference line is equidistant from the horizontal reference line, and a scale ruler and a liquid level meter are arranged at the scale reference line.
[0007] Furthermore, the zero scale value of the scale ruler and the bottom of the level meter are flush with the scale reference line; in the initial vertical state, the readings of each level meter are the same.
[0008] Compared with the prior art, the present invention has the following beneficial effects: The measuring device of the present invention has a simple structure. When measuring, the operator is located at the construction joint above the cylinder wall, observes the scale ruler at the scale reference line, and can monitor the horizontality of the cylinder wall at any time through the numerical difference between the liquid level of the liquid level meter and the scale ruler. The present invention does not require a measuring instrument, and can accurately determine the specific numerical value of the deviation at any time, which is convenient and quick.
[0009] In a second aspect, the present invention provides a method for measuring the horizontality of a cyclone wellbore wall during a caisson sinking process, comprising the following steps: Step 1: Marking the scale reference line After the first section of the cylinder wall is cast and prefabricated and the formwork is removed, multiple horizontal reference lines of the same height are evenly set around the bottom of the first section of the cylinder wall; the horizontal reference lines are evenly distributed around the first section of the cylinder wall; a scale reference line is set upward from the horizontal reference line, and the scale reference line and the corresponding horizontal reference line are at the same vertical position, and a scale ruler and a liquid level gauge are installed at the scale reference line as required, and one of the scale reference lines is selected as the original reference point, and the remaining scale reference lines are used as observation reference points; Step 2: Horizontal measurement of the first section of the caisson wall As the earthwork below the blade foot of the vortex shaft wall is excavated, the vortex shaft wall begins to slowly sink. When the shaft wall tilts, the liquid surface in the level gauge will tilt, and the corresponding scale will have different readings. Compare the scale readings of the observation reference point with the original reference point, calculate the horizontal deviation value, and take appropriate correction measures according to the horizontal deviation. Step 3: Horizontal measurement of the second section of the caisson wall When the first section of the cylinder wall is caissoned in place, the second section of the cylinder wall is constructed. According to the method of the first step, after the template is removed from the second section of the cylinder wall, the scale reference line position is transferred and extended upward, that is, the scale reference line on the upper part of the original first section of the cylinder wall is used as the horizontal reference line of the second section of the cylinder wall, and then the scale reference line is set on the upper part of the second section of the cylinder wall; according to the method of the second step, the horizontal deviation between the original reference point and the observation reference point is calculated to obtain the horizontal deviation of the vortex well cylinder wall, so as to provide data for timely correction of the vortex well cylinder wall caisson, and take appropriate correction measures; Step 4: Repeat step 3 until all sections of the cyclone shaft wall are sunk.
[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. No measuring instruments are needed, the specific value of the deviation can be directly determined by observing the readings, making the construction convenient, fast and efficient.
[0011] 2. No professional surveyors or measuring instruments are needed, general workers can achieve it.
[0012] 3. The data can not only monitor the horizontal changes of the entire cylinder wall caisson process at any time, but also monitor the uneven settlement and tilt changes of the cylinder wall as the load increases or decreases during the construction process.
[0013] 4. The operator works inside the construction joint wall at the upper part of the cylinder wall. The reserved steel bars inside and outside the wall act as guardrails. There is no need to go down to the bottom of the cylinder wall to work. The construction conditions are good, safe and reliable.
[0014] The preferred solution of the present invention is that the number of horizontal reference lines is 4, and scale reference lines are set upward at the same vertical position, which are respectively recorded as points "A", "B", "C", and "D", and are distributed in four directions around the vortex shaft wall, among which point "A" is used as the original reference point, and points "B", "C", and "D" are observation reference points; When measuring, the scale value corresponding to the liquid level of the level gauge at point "A" is "L A ", and the scale value corresponding to the liquid level of the "B" point level gauge is "L B ", the gap between the two AB =L A -L B That is the horizontal deviation of point "B"; when e AB When it is negative “-”, it means that point “B” sinks faster relative to the original reference point “A”. AB When it is positive "+", it means that point "B" sinks slowly relative to the original reference point "A", and correction measures need to be taken; the horizontal deviation e of point "C" is obtained in the same way. AC =L A -L C , horizontal deviation of point "D" eAD =L A -L D , take appropriate corrective measures in time according to the horizontal deviation.
[0015] Furthermore, the horizontal reference line and the scale reference line are arranged on the inner side or the outer side of the vortex shaft wall for easy operation.
[0016] Furthermore, the scale reference line is located 100 to 300 mm below the construction joint position of the vortex shaft wall for easy operation.
[0017] Furthermore, the method for setting the scale reference line is to use a ruler to measure the same length value upwards on the horizontal reference line, and make a mark at this position, which is the scale reference line.
[0018] Furthermore, the measuring ruler adopts a steel measuring tape, a plumb bob or an ink line.
[0019] Furthermore, the level meter adopts a transparent short tube, which is filled with water and added with pigment to enhance the observation effect. BRIEF DESCRIPTION OF THE DRAWINGS

When the shaft wall tilts, the liquid level in the level gauge 4 tilts, and the corresponding scale 3 has different readings. The readings of the scale 3 at the observation reference point and the original reference point are compared to calculate the horizontal deviation value, and appropriate correction measures are taken according to the horizontal deviation. Step 3: Horizontal measurement of the second section of the cylinder wall 102 caisson When the first section of the cylinder wall 101 is caissoned in place, the second section of the cylinder wall 102 is constructed. According to the method of the first step, after the template is removed from the second section of the cylinder wall 102, the position of the scale reference line 202 is transferred and extended upward, that is, the scale reference line 202 on the upper part of the original first section of the cylinder wall 101 is used as the horizontal reference line 201 of the second section of the cylinder wall 102, and then the scale reference line 202 is set on the upper part of the second section of the cylinder wall 102; according to the method of the second step, the horizontal deviation between the original reference point and the observation reference point is calculated to obtain the horizontal deviation of the vortex shaft wall 1, so as to provide data for timely correction of the caisson of the vortex shaft wall 1, and take appropriate correction measures; The fourth step is to repeat the third step until all sections of the cyclone shaft wall 1 are sunk.
[0025] In some embodiments, the horizontal reference line 201 and the scale reference line 202 can be set on the inner side of the vortex shaft wall 1, or can be set on the outer side of the vortex shaft wall 1, whichever is more convenient for operation.
[0026] In some embodiments, the number of horizontal reference lines 201 and scale reference lines 202 at the same level may be 4, 6, 8 or other numbers, and the specific number is determined according to actual conditions.

The measuring ruler adopts a plumb line, and the liquid level meter 4 adopts a transparent plastic short tube. The liquid level meter 4 is filled with water of the same height, and pigment is added to the water.
[0032] More specifically, after the first section of the cylinder wall 101 is cast and prefabricated and the formwork is removed, a level is set up on the inner side of the vortex shaft wall 1, and the rotating instrument is used to make four horizontal reference lines 201 around the cylinder wall with a marker, which are evenly distributed in four directions around the vortex shaft wall 1.

[0034] When measuring, the value of the scale 3 corresponding to the liquid level of the level gauge 4 at point "A" is "L A ", and the value of the scale ruler 3 corresponding to the liquid level of the "B" point level gauge 4 is "L B ", the gap between the two AB =L A -L B That is the horizontal deviation of point "B"; when e ABWhen it is negative “-”, it means that point “B” sinks faster relative to the original reference point “A”. AB When it is positive "+", it means that point "B" sinks slowly relative to the original reference point "A", and correction measures need to be taken; the horizontal deviation e of point "C" is obtained in the same way. AC =L A -L C , horizontal deviation of point "D" e AD =L A -L D , take appropriate corrective measures in time according to the horizontal deviation.
[0035] When the first section of the cylinder wall 101 is caissoned in place, the construction of the upper second section of the cylinder wall 102 is carried out.

[0036] The measuring device of the present invention has a simple structure, and the horizontality of the cylinder wall can be monitored at any time by the numerical difference between the liquid level of the liquid level meter 4 and the scale ruler 3. During measurement, the operator is located at the construction joint 5 above the cylinder wall, observes the scale ruler 3 at the scale reference line 202, and can monitor the horizontality of the cylinder wall at any time by the numerical difference between the liquid level of the liquid level meter 4 and the scale ruler 3. This construction method does not require the use of measuring instruments, and the specific numerical value of the deviation can be accurately determined at any time, which is convenient and quick.
