Description

[0002] With the rapid economic development of the city, the urban infrastructure in the central urban area can no longer meet the current needs.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0045] Example 1: Please refer to Figure 1-Figure 10 A coordinate restoration and layout construction device comprises a total station body 1, a tripod 2, a connecting base 3, a level detection component, a fine-tuning component and an auxiliary support accessory; wherein the total station body 1 is arranged on the tripod 2, and a connecting base 3 is fixedly arranged at the bottom end of the tripod 2; a level detection component is arranged between adjacent connecting bases 3, a fine-tuning component is arranged at the bottom end of the connecting base 3, and the fine-tuning component is connected to the auxiliary support accessory.

[0046] An operating method of a coordinate restoration and setting-out construction device, the operating method comprising:

[0047] S1: Control point layout

[0048] The construction unit provides the first-level control points and sets up the second-level encrypted control points in the construction site; the elevation control points are arranged at the outer wall columns of the original structure and marked with red triangles;

[0049] S2: Total Station Traverse Measurement

[0050] Adopt the attached traverse measurement method, set up the total station that has been identified and calibrated at the control point, set the temperature, air pressure and other parameters according to the actual situation, accurately align and level; two prisms are respectively set at the adjacent control points in front and behind the measuring station; aim at the rear point at the left position of the disk, manually set the horizontal angle to zero, and record the horizontal angle reading at this time on the observation record sheet. Then measure the distance, select the stable value after multiple measurements, and record the data.

[0051] Aim at the front point at the left position of the disk. The horizontal angle reading will change. Record the change value. Repeat the previous step. Complete the first half of the measurement.

[0052] Aim at the rear point at the right side of the plate, record the horizontal angle reading, measure the distance and record the reading; aim at the front point at the right side of the plate, record the horizontal angle reading, measure the distance and record the reading; one measurement is completed.

[0053] Repeat the above steps to complete the second measurement (the starting position is 90 degrees).

[0054] S3: Adjustment calculation

[0055] 1) Make an adjustment calculation table and fill in known data

[0056] Enter the starting and ending coordinates of the starting side and the attached side as required and calculate the azimuth and side length. Then refer to the observation record table and fill in each measuring point in the "Measurement Point" column in turn, fill in the average angle value measured at each measuring station in the "Observation Left Angle Value" column, and fill in the average side length of each traverse side in the "Distance" column.

[0057] 2) Calculate the angle closure error

[0058] The purpose of calculating the angle closure error is to check whether the accuracy of the field angle observation meets the technical requirements of the corresponding grade of traverse. If the measured angle closure error is less than the allowable angle closure error, the field angle observation is qualified and adjustment can be performed; otherwise, if the field observation is unqualified, re-observation is required.

[0059] Measured angle closure error = measured azimuth of the side - theoretical azimuth of the side

[0060] Measured azimuth of the attached side = azimuth of the starting side - N*180 + sum of measured left angle values

[0061] There are corresponding regulations for the allowable angle closure error for each grade of conductor (the technical requirements for each grade of conductor are in the previous article).

[0062] Note: N is the number of measuring stations. The azimuth angle ranges from 0 degrees (inclusive) to 360 degrees (exclusive). If it is greater than 360 degrees, subtract 360 degrees. If it is less than 0 degrees, add 360 degrees.

[0063] 3) Calculate the left angle correction

[0064] After calculating the angle closure error and determining that the field results are qualified, it is necessary to calculate the left angle correction.

[0065] Left angle correction = the opposite of the angle closure error / number of measuring stations

[0066] Corrected left angle value = observed left angle value + left angle correction value

[0067] 4) Calculate the azimuth of each conductor edge

[0068] Starting from the azimuth data of the starting side, the azimuth of each line side is calculated side by side. Formula:

[0069] The azimuth of the traverse side = the azimuth of the previous side + 180 degrees + the corrected left angle value of the station

[0070] 5) Calculate the coordinate increment closure error

[0071] Before calculating the coordinate increment closure error, you must first calculate the coordinate increment and fill in the corresponding position, and then sum the X coordinate increment and Y coordinate increment respectively.

[0072] X coordinate increment = distance (i.e. side length) * COS (azimuth)

[0073] Y coordinate increment = distance (i.e. side length) * SIN (azimuth)

[0074] X-coordinate incremental closure error = sum of X-coordinate increments - (X-coordinate of the end point of the attached edge - X-coordinate of the starting point of the initial edge)

[0075] Y coordinate incremental closure error = sum of Y coordinate increments - (Y coordinate of the end point of the attached edge - Y coordinate of the starting point of the starting edge)

[0076] 6) Calculate the full-length closure error of the conductor and the relative closure error of the full-length of the conductor

[0077] The purpose of calculating the relative closure error of the full length of the wire is to verify whether the accuracy of the field distance measurement meets the technical requirements. The calculation formula is:

[0078] The total length of the conductor is closed = square root (the square of the incremental closure error of the X coordinate + the square of the incremental closure error of the Y coordinate)

[0079] Relative closure error of the entire conductor length = closure error of the entire conductor length / total length of the conductor (i.e. the sum of the side lengths)

[0080] The allowable value of the relative closure error of the entire length of the conductor has corresponding regulations for each level of conductor. If the calculated relative closure error of the entire length of the conductor is less than the allowable value, the field distance measurement accuracy is qualified and the adjustment calculation can continue; otherwise, it is unqualified and needs to be re-measured.

[0081] 7) Calculate the coordinate increment correction number and the corrected coordinate increment of each wire edge

[0082] The coordinate increment correction is similar to the left angle correction. After reversing the sign of the coordinate increment closure error, distribute it in proportion to the measured side length of each conductor. Calculation formula:

[0083] The X-coordinate increment correction number of a certain wire side = the opposite number of the X-coordinate increment closure error * (the measured length of the side / the total length of the wire)

[0084] The Y-coordinate increment correction number of a certain wire side = the opposite number of the Y-coordinate increment closure error * (the measured length of the side / the total length of the wire)

[0085] Corrected coordinate increment = coordinate increment + coordinate increment correction number

[0086] 8) Calculate the coordinates of each control point

[0087] Based on the starting point coordinates of the starting edge, the calculation formula is:

[0088] X coordinate = X coordinate of the previous point + corrected coordinate increment of the station;

[0089] Y coordinate = Y coordinate of the previous point + corrected coordinate increment of the measuring station.

[0090] For coordinate transformation

[0091] In small-area projects, the plane rectangular coordinate system does not need to take into account the curvature of the earth. Therefore, the coordinate transformation generally adopts the "three-parameter" method (two translations ΔN, ΔE, and one rotation α) for coordinate transformation calculation.

[0092] Review of the original structure

[0093] 1) Review of the original axis

[0094] Using the polar coordinate method, the main axis of the new structure is projected and compared with the axis of the original structure. The deviation direction and deviation data of the two axes are calculated, and the review results are submitted to the designer for reasonable adjustments in subsequent construction.

[0095] 2) Review of original elevation

[0096] Use the points provided by the Surveying and Mapping Institute to review the one-meter line on each floor of the original structure, submit the review results to the design party, and make reasonable adjustments in subsequent construction.

[0097] For axis placement

[0098] The axis is placed by using the wire measurement to guide the control points. After the excavation of the foundation pit and the pouring of the cushion layer in each section, the foundation slab axis is placed. The total station is used to cast points on the cushion layer, and the main control axis is first popped up. Then the total station is moved into the pit, and the four sides of the main axis are closed. After verification, other axes are drawn out, and the relationship with the existing structure is verified. After correction, it is used as the basis for the construction of the foundation slab structure.

[0099] The axis of the upper structure is placed. The control axis is measured from the reserved opening to each floor, and the axis position can be released when necessary. At the same time, on the 0m level structure, measurement embedded parts are set according to the reserved opening position. The control points must be checked against each other each time they are conducted, and records are kept to check the distance and angle between each point until they fully meet the requirements.

[0100] For elevation control

[0101] After the reinforcement of the foundation slab and basement floor slab is tied, the elevation is measured on the permanent structure and marked with red paint. There are no less than 4 points around the foundation pit (no less than 1 point in each direction) as the elevation control points when pouring concrete for the foundation structure; where there is no inserted reinforcement, short steel bars are welded and marked to ensure that the distance between the elevation control points does not exceed 4m. The red paint mark is marked 500mm above the bottom plate surface to prevent the control points from being contaminated by concrete slurry and becoming unrecognizable when pouring concrete.

[0102] The elevation control points of the upper structure are arranged on the tower crane at the construction site. Inverted triangles are marked with red paint, and the elevation data is noted as a basis for the subsequent level elevation measurement. For the elevation control points, regular reviews are conducted to avoid errors caused by the settlement of the tower crane, which may affect the level elevation of the building. As the building rises, a steel ruler is used to divide the sections into 1 ruler for every 2 floors (within 10m) (and converted once) to control the required elevation of each floor. Each measurement is strictly based on the principle of drawing from the elevation control point to avoid cumulative errors. The elevation of each point on the floor is measured and set using an S3 level according to the measured elevation.

[0103] Example 2: Based on Example 1, please refer to Figure 2 The horizontal detection component here includes a connecting plate body 401, a connecting rod 402, a connecting sleeve 403 and a spirit level 404; the connecting sleeves 403 are symmetrically fixedly arranged at both ends of the spirit level 404, and the connecting rod 402 is movably inserted in the connecting sleeve 403, and a connecting plate body 401 is fixedly arranged at one end of the connecting rod 402, and the connecting plate body 401 is fixedly connected to the side wall of the connecting base 3 by screws.

[0104] This solution sets a level detection component between the tripod 2 and observes the state of the level meter 404. After the total station is placed, it can be quickly checked whether it is in a horizontal state, thereby avoiding unnecessary adjustment and testing operations.
