Description

Technical Field

[0001] The invention relates to a measuring and positioning device for artificial bored piles, which is a measuring and positioning device for artificial bored piles in the construction field. Background Art

[0002] With the rapid development of my country's construction industry, manual bored pile construction has become a common method of pile hole excavation. The accuracy, speed and convenience of measuring and positioning of manual bored piles directly affect the quality of manual bored piles and subsequent main construction.

[0003] In traditional manual bored pile construction, a total station is usually used to measure the midpoint of the pile. Construction workers measure the midpoint of the pile, and then use a hammer to determine the center position of the hole and the thickness of the retaining wall for each mold according to the hole opening positioning point. This method has a large deviation and is not conducive to the control of the quality of manual bored pile construction.

[0004] The traditional method of hanging wires requires multiple point measurements and verifications to reduce errors. It consumes a lot of manpower, is inefficient, has large deviations, and is prone to safety risks such as falling from heights during operation.

[0005] Traditional manual hole digging requires locating four points passing through the center of the circle at the lock mouth and using a wire to make a cross wire to determine the hole. This method is cumbersome to operate and the hole mouth point is easily affected by construction and difficult to protect.

[0006] In previous manual hole digging construction, the pile center was determined by pulling a wire rope at a positioning point. This was easily affected by the tension of the rope and could easily cause deviations. In addition, the wire rope itself was soft and was greatly affected by external disturbances. Summary of the invention

[0007] The purpose of the present invention is to improve the traditional bored pile positioning device so that it can be effectively used in the common artificial bored pile measurement and positioning, and is suitable for the construction of artificial bored piles with common hole diameters (except large piles with a pile diameter of several meters).

[0008] The present invention achieves the above-mentioned purpose through the following technical solutions: a manual bored pile measurement and positioning device, including two stainless steel rods with scales and a through groove in the center, connecting bolts, a level bubble, four reels with scales and a plumb bob. The distance from the positioning point on the manual bored pile lock to the center of the bored pile hole is carded out on the stainless steel rod, and the center position of the hole is determined by the free opening and closing of the two rods with scales; the level of the device is controlled by the middle horizontal bubble; the pile diameter and hole diameter are determined by moving the reel in the groove to the corresponding pile diameter scale; the excavation depth is determined by lowering the line plumb by the reel with scale, so as to achieve the purpose of controlling the center, verticality, excavation depth, excavation wall thickness and other parameters of the manual bored pile.

[0009] The stainless steel rod with scales and a groove running through the center is 2.4 m long and 3 cm wide. The width of the middle groove is 0.5 cm. Scales are continuously marked in millimeters from the center of the rod to both ends.

[0010] The connecting bolt is an M12 bolt, which is used to penetrate holes of the same size in the center of two stainless steel rods, so as to connect the rods and rotate with the bolt as the axis.

[0011] The level bubble is fixed to the top of the connecting bolt and is used for leveling the device, for controlling the accuracy of the horizontal direction of the device, and for controlling errors.

[0012] The wire reel has a scale mark in centimeters. The wire rope can be locked at any length after being extended. The wire reel can slide along the stainless steel rod and can be locked at a fixed position.

[0013] The plumb bob has a size of 1400*700*400mm*4 and is connected to a scale line for reference in measuring hole depth, verticality and hole diameter.

[0014] The various components of the device are coordinated and unified, and the operation is simple, which can effectively improve the efficiency and accuracy of manual bored pile measurement and positioning.

[0015] The advantages of the present invention are:

[0016] 1. The materials are simple and easy to obtain.

[0017] 2. The device has simple parts and components and is easy to operate, making it suitable for the changing and complex environment of the construction site.

[0018] 3. The device effectively improves the efficiency of manual bored pile measurement and positioning, and the accuracy of verticality, hole position, etc. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the scaled stainless steel rod 1 is placed on the point where the measurement is drawn according to the scale according to the hole size, the position of the two stainless steel rods is adjusted by the connecting bolt 6 to determine the center point of the hole, the level of the leveling rod is observed by the level bubble 2, the position of the scaled wire reel 3 on the stainless steel rod 1 is adjusted according to the hole diameter, and the scaled wire rope 7 and the plumb bob 5 are released to control the hole depth and hole position at the lower side of the bored pile.

[0025] The stainless steel rod with scales and a groove running through the center is 2.4m long and 3cm wide. The width of the middle groove is 0.5cm. 0~105mm scales are continuously marked in millimeters from the center of the rod to both ends. The material is 304 stainless steel.

[0026] The connecting bolt is an M12 bolt, which is used to penetrate holes of the same size in the center of two stainless steel rods, and serves the purpose of connecting the rods and rotating with the bolt as the axis. After the rods are connected, the two rods can rotate freely with the bolt as the axis.

[0027] The level bubble is fixed to the top of the connecting bolt and is used for leveling the device, for controlling the accuracy of the horizontal direction of the device, and for controlling errors.

[0028] The wire reel has a scale mark in centimeters. After the wire rope is extended, it can be locked at any length. The wire reel can slide along the stainless steel rod and can be locked at a fixed position to measure the depth of the manually dug hole.

[0029] The size of the plumb bob is 1400*700*400mm*4 pieces, with two on each stainless steel rod, connected with a scale rope, and the position can be adjusted according to the scale on the rod groove based on the hole diameter, which is used as a reference for measuring hole depth, verticality and hole diameter.

[0030] The whole device is used together with the measuring points to control the parameters related to manual digging more efficiently and accurately.

[0031] Production and use steps:

[0032] 1. Make the artificial bored pile measurement and positioning device: use two stainless steel rods with a length of 2.4m, a width of 3cm, and a thickness of 0.5cm as materials, and continuously carve 0~105mm scales on both sides of the center of the rod, and carve a 0.5cm wide through groove in the center of the length direction of the rod. Drill a hole of appropriate size in the geometric center of the short side of the rod, and connect the two rods with M12 bolts. After connection, the two rods can rotate freely with the bolt as the axis. A reel with scales is installed on the grooves at both ends of each rod, and the reel can slide freely on the groove of the rod as needed. Each reel is connected with a scaled rope and a plumb bob, which can be freely lowered to a fixed length to be stuck, so as to measure the hole depth and verify the hole position. When in use, place the rod at the hole mouth according to the scale on the rod corresponding to the measurement point, and rotate the rod to determine that the bolt position is the center position of the hole. Level the horizontal bubble to ensure that the entire device is level and eliminate the error caused by the uneven device. According to the diameter of the bored pile, adjust the position of the reel on the groove of the stainless steel rod according to the scale, lower the scaled rope and plumb bob to measure the hole depth and size below the hole mouth, and perform measurement and positioning to reduce deviation.

[0033] 2. When not working, fold up the reel and rotate the two rods together with the bolt as the axis, which is convenient for storage without taking up extra space.
