Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit engineering, and in particular to a device and method for positioning anchor holes reserved for pile rows. Background Art

[0002] With the continuous development of the economy and the accelerating process of urbanization, ensuring the safety and normal use of buildings, underground pipelines and roads around the foundation pit during construction has become an urgent problem to be solved. "Pile rows + anchor rods" as an efficient and economical anchor-pull structure are widely used to solve the deformation problem of deep foundation pits.

[0003] In the prior art, there are two ways to deal with the problem of inaccurate anchor positioning when pouring pile concrete on site: Method 1: After the foundation pit is excavated to the anchor design elevation, the anchor is laid in the gap between the piles, and the end of the anchor is connected to the waist beam, and the tension of the anchor is transmitted to the piles through the waist beam, so as to achieve the purpose of controlling the deformation of the foundation pit and surrounding structures by the pile + anchor support structure; Method 2: After the foundation pit is excavated to the anchor design elevation, an anchor drilling machine is used to drill holes in the pile body, and the anchoring force acts directly on the pile body through the anchor, so as to achieve the purpose of controlling the deformation of the foundation pit. The above two methods have the following defects in actual application:

[0004] The defects of method 1: the anchor force can only be applied after the waist beam reaches the designed strength. After the foundation pit is excavated, it is exposed to the external environment for a long time, and the deformation of the buildings around the foundation pit cannot be controlled in time, which easily induces the instability of the foundation pit.

[0005] The defects of method 2 are: it is necessary to drill holes on the piles that have reached the designed strength, which is difficult to construct and can easily damage the stress-bearing steel bars of the piles, thus affecting the stress of the piles and ultimately affecting the quality of the piles.

[0006] Therefore, there is an urgent need for a device that can quickly locate the reserved anchor holes without affecting the stress of the "pile row + anchor rod" support, so as to better play the advantages of the "pile row + anchor rod" support structure in deformation control.

[0086] The present disclosure also provides a method for positioning reserved anchor holes in a pile row, which is applied to the above-mentioned reserved anchor hole positioning device in a pile row, and comprises the following steps:

[0087] S1. Reserve an anchor sleeve 202 in the anchor hole, set the fixing module at the port of the anchor hole, and rotate the connecting tube 101 in combination with the measuring instrument, so that the positioning rod 102 and the connecting tube 101 rotate synchronously, and rotate to the position where the axis of the positioning rod 102 is coplanar with the axis of the anchor sleeve 202; when the axis of the positioning rod 102, the axis of the anchor sleeve 202 and the measuring instrument form three points located on a straight line, the axis of the positioning rod 102 is aligned with the axis of the anchor sleeve 202, that is, the axis of the positioning rod 102 is coplanar with the axis of the anchor sleeve 202;

[0088] S2, rotating the sleeve 202, so that the guide rod 201 and the sleeve 202 rotate synchronously, until the axis of the guide rod 201 is parallel to the direction indicated by the North Pole of the compass 301;

[0089] S3. According to the preset azimuth angle of the anchor hole, the connecting pipe 101 is rotated so that the scale pointer 303 rotates to point to the scale value of the dial 302 consistent with the azimuth angle, thereby completing the positioning of the anchor hole.

[0090] Furthermore, in this embodiment, step S3 specifically includes:

[0091] The preset azimuth angle is A L After the axis of the guide rod 201 is parallel to the direction indicated by the North Pole of the compass 301, adjust the scale pointer 303 to point to the scale value of the dial 302 to 0; preset the azimuth angle A L The value ranges from 0 to 15°;

[0092] The angle of rotating the connecting pipe 101 is equal to A L After the rotation is completed, the actual scale value A of the scale pointer 303 pointing to the scale plate 302 is obtained. S , and determine the actual scale value A S Whether it meets the positioning requirements;

[0093] If A S =[A L -Q, A L +Q], then the actual scale value A is determined S Meet the positioning requirements and complete the positioning of the anchor hole;

[0094] If A S ≠[A L -Q, A L +Q], then the actual scale value A is determined S Does not meet the positioning requirements, and executes the correction strategy until A is met S =[A L -Q, A L +Q];

[0095] Where Q represents the angle allowable error value;

[0096] The deviation correction strategy includes angle increment strategy and angle decrement strategy;

[0097] If A S >A L +Q, then the angle reduction strategy is adopted;

[0098] If A S <A L -Q, then the angle increment strategy is adopted;

[0099] Angle reduction strategies include:

[0100] The connecting tube 101 is rotated several times in the direction of decreasing the scale value of the dial 302 until the A S =[A L -Q, A L +Q], the angle of each rotation is 0.2*[A S -(A L +Q)];

[0101] Angle increment strategies include:

[0102] The connecting tube 101 is rotated several times in the direction of increasing scale value of the dial 302 until A is satisfied. S =[A L -Q, A L +Q], the angle of each rotation is 0.2*[(A L -Q)-A S ];

[0103] Here is an example:

[0104] The preset azimuth angle is A L = 10°, obtain the actual scale value A of the dial 302 pointed by the scale pointer 303 S =8°, angle tolerance Q = 1°, A L -Q = 9°, A L +Q = 11°;

[0105] Then A S ≠[9°, 11°], then determine the actual scale value A S Failure to meet positioning requirements and implementation of correction strategies;

[0106] And A S <A L -Q=9°, then the angle increment strategy is adopted to rotate the connecting tube 101 in the direction of increasing scale value of the scale plate 302, and the angle of each rotation is 0.2*[(A L -Q)-AS ]=0.2*1=0.2°, the number of rotations is at least 1 / 0.2=5 times, until A is satisfied S =[A L -Q, A L +Q], complete the positioning of the anchor hole;

[0107] In summary, the method for positioning the reserved anchor holes in pile rows provides stable support for the rotation of the positioning rod and the connecting pipe by setting a fixing module at the port of the anchor hole, and combining with the measuring instrument to make the axis of the positioning rod 102 and the axis of the anchor sleeve precisely coplanar; by rotating the sleeve 202, the guide rod 201 is driven to accurately align with the North Pole direction of the compass 301 to establish an accurate azimuth reference; by rotating the connecting pipe 101, the dial pointer 303 is accurately pointed to the preset azimuth angle scale, and the linkage of multiple components ensures high positioning accuracy;

[0108] In addition, step S3 utilizes the dial 302 to accurately control the preset azimuth angle, and through error judgment and correction strategies, controls the positioning error within the prescribed allowable range, effectively ensuring the high accuracy of anchor hole positioning, and providing precise basic conditions for subsequent anchor installation and coordinated force between piles and anchors, greatly improving the reliability and stability of the entire "pile row + anchor" support structure, and reducing the risks of uneven structural force and excessive deformation due to positioning deviations.
