Description

Technical Field

[0001] The invention relates to a column positioning and verticality control device, in particular to a corrugated beam steel guardrail column positioning and verticality control device, belonging to the technical field of road engineering. Background Art

[0002] As a common solution for driving safety protection on domestic highways of all levels, the construction of corrugated steel guardrail columns is the key and difficult part of the construction of corrugated steel guardrails. The quality of its construction directly affects the qualified rate of the inspection and evaluation results. Therefore, the quality control of the construction of corrugated steel guardrail columns is particularly important.

[0003] The more mature existing corrugated beam steel guardrail construction is to use a hydraulic pile driver to drive the guardrail posts into the roadbed soil, and then manually install the corrugated crossbeam on the connecting parts with tools such as crowbars, eventually forming a corrugated beam steel guardrail that connects the road sections.

[0004] Guardrail positioning and setting out is divided into three steps:

[0005] 1. Locate the center distance between the columns; currently, two people are required to work together and use a 5m steel tape measure to measure the average spacing of 4m or 2m in sections according to the drawing requirements. The 2m average spacing is measured by taking the center point of the 4m average spacing to reduce the cumulative error. After the section measurement, it is marked on the pavement structure with a paint pen or a marker;

[0006] 2. Horizontal distance between the column and the road reference object is staked out; after the center distance between the columns in the previous step is staked out, use the marked average spacing mark points as a reference, extend horizontally according to the drawing requirements, and measure the horizontal distance to the road reference object. Also, one person is used with the same 5m tape measure to reduce the allowable error of the tool itself. Then mark the horizontal distance with paint on the median strip or shoulder. Unlike the previous step of positioning and staking out, which can be done with a marker pen, the positioning points for this stakeout are often set on the fill of the median strip or on the earth shoulder, so paint marking is easier to operate and easier to find points for the subsequent column driving process;

[0007] 3. Positioning the depth of the column: The exposed length of the column is calculated by converting the technical indicator of the height between the center of the corrugated beam and the road surface. The road surface or curb is often used as the basic surface. After the exposed length of the column is calculated, a single person uses the same 5m tape measure and marker to mark a line on the surface of the column coating.

[0008] The pillars are driven in by a hydraulic pile driver in combination with manual labor:

[0009] One operator moves the column to the driving position, aligning the bottom center with the horizontal distance positioning point. Another operator uses the same 5m tape measure to re-measure the horizontal distance point covered by the bottom of the column to ensure that the column is driven into the correct position. The hammer head of the hydraulic pile driver is inserted into the upper end of the column. The operator of the hydraulic pile driver operates the machine to slowly drive the column in. During the driving process, one of the cooperating personnel constantly re-measures the verticality of the column with a level ruler, and constantly communicates with the operator of the hydraulic pile driver with gestures about the direction that needs to be corrected. When the driving depth mark point is basically reached but not yet reached, the cooperating personnel uses a level ruler to place the road surface or curbstone horizontally for continuous observation, and uses gestures to communicate with the operator of the hydraulic pile driver about the depth that needs to be driven in.

[0010] After the guardrail column construction is completed, the next column is driven in, and the process is the same as above. After the continuous columns are driven in, the manual hanging board operation is carried out until the product corrugated beam guardrail of the road section length is formed.

[0011] In the existing construction process of corrugated steel guardrail columns, multiple different and necessary layout processes are required; during the driving process of the column, manpower is needed to re-measure the pile position to see if it is accurate; the control of verticality also requires continuous communication between the hydraulic pile driver operator and the supporting personnel during the slow driving process, which requires a high degree of cooperation from the work team; the depth of the column still needs to be continuously observed by the personnel with the level ruler, and the operator needs to maintain communication. In the existing corrugated steel guardrail column construction process, it is impossible to replace the work of personnel by using some practical and efficient tools.

[0012] Therefore, it is necessary to provide a device for positioning and controlling the verticality of a corrugated beam steel guardrail column. Summary of the invention

[0013] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a device for positioning and controlling the verticality of a corrugated beam steel guardrail column.

[0026] Furthermore, the sleeve is a round tube with a length of 50 mm, a diameter of 20 mm and a thickness of 2 mm.

[0027] The present invention is beneficial in that:

[0029] The control device of the present invention has a simple structure and is easy to use. It can efficiently locate the distance between the guardrail column and the edge of the road surface.

[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] A device for positioning and controlling the verticality of a corrugated steel guardrail column comprises a base 1, a support rod 2, a first position limiting tube 3, a transverse rod 4, a second position limiting tube 5, a longitudinal rod 6, a first horizontal end 7, and a second horizontal end 8.

[0035] Preferably, the base is a Φ150mm, 10mm thick steel plate. The support rod is vertically arranged on the top surface of the base, and preferably, the support rod is a Φ15mm, 2mm thick steel pipe with a length of 200mm.

[0036] The first position limiting tube is composed of a sleeve with a screw hole and a bolt. Preferably, the sleeve is a Φ20mm steel pipe with a length of 50mm and a thickness of 2mm. The sleeve is horizontally arranged at the top of the support rod.

[0037] The transverse rod is horizontally placed in the sleeve and is locked by tightened bolts. Preferably, the transverse rod is a steel pipe with a length of 900 mm and a diameter of 15 mm and a thickness of 2 mm.

[0038] The second limiting tube is composed of a sleeve with a screw hole and a bolt. Preferably, the sleeve is a 50mm long Φ20mm, 2mm thick steel tube. The sleeve is vertically arranged at the end of the transverse rod along the longitudinal direction.

[0039] The longitudinal rod is placed in the sleeve of the second limit tube along the longitudinal direction and is locked by tightened bolts. Preferably, the longitudinal rod is a Φ15mm steel pipe with a length of 600mm and a thickness of 2mm.

[0040] The first horizontal end and the second horizontal end are horizontally arranged at the top and bottom of the longitudinal rod respectively. Preferably, the first horizontal end and the second horizontal end are square steel pipes of 15*15mm and 2mm thick respectively. Moreover, the first horizontal end and the second horizontal end are parallel to the transverse rod, that is, they are in the same longitudinal plane as the transverse rod. The first horizontal end and the second horizontal end are also provided with a level meter respectively, and the level meter is preferably a strong magnetic base level bubble 9 that can be adsorbed on the square steel pipe.

[0041] When using,

[0042] A. After completing the first step of staking out the center distance between the columns, place the base horizontally on the staking out mark point, visually inspect the state of the level bubble on the first horizontal end and the second horizontal end to determine whether the device is level, and cooperate with manual fine-tuning to ensure that the device is in a horizontal state.

[0043] The construction technicians calculate the lateral distance between the column and the road reference object according to the design requirements of the drawings, adjust the lateral rod to the required length of the lateral distance between the column and the road reference object by pulling the lateral rod laterally, and then tighten the bolts on the lateral rod.

[0044] The above operation controls the lateral distance between the column and the road reference object by adjusting the total lateral working length and locking it with bolts.

[0045] During the construction process, it is only necessary to horizontally place the device one by one at the center distance marking point between the columns. During the column driving process, ensure that the column always keeps in contact with the first and second horizontal ends, so as to ensure the lateral distance between the column and the road reference object.

[0046] The use of this device directly reduces the process of staking out the lateral distance between the column and the road reference object. It only requires continuous visual observation of the contact status during the column driving process, thereby achieving the actual construction effect of continuous inspection and correction.

[0047] B. The penetration depth of the guardrail column is converted into the exposed length of the column through the technical indicator of the height from the center of the corrugated beam to the road surface.

[0048] The existing highway engineering corrugated beam guardrail construction technical specifications require that the guardrail center height meet 600mm / 697mm. Adjust the total vertical working length of the device to 600mm / 697mm and lock it with bolts. During the column driving process, the hydraulic pile driver operator operates the hydraulic pile driver hammer to continuously drive the column into the median strip or shoulder soil. The construction workers on the side observe with the naked eye whether the first horizontal end of the upper part coincides with the column driving depth mark line. When the first horizontal end coincides with the column driving depth mark line, it means that the column driving depth meets the design requirements.

[0049] In the existing construction process, when the depth mark point is basically reached but not yet reached, the coordinating personnel use a level ruler to place the road surface or curbstone horizontally for continuous observation, and use gestures to communicate with the hydraulic pile driver operator about the depth that needs to be driven in. The working principle of this device is simple and only requires naked eye observation.

[0050] C. Verticality control during column driving:

[0051] In the existing construction process, the verticality of the column is constantly re-measured by the cooperating personnel with a level during the process, and the direction that needs to be corrected is communicated with the hydraulic pile driver operator.

[0052] Through the use of this device, the cooperative personnel will place the device horizontally on the road surface or reference object, so that the magnetic level bubbles on the first and second horizontal ends are adjusted to the level, and the first and second horizontal ends are in continuous contact with the driven guardrail column to form two contact points; based on the principle that the axis formed by the contact points is parallel to the axis of the column, the verticality of the column is ensured. During the driving process, the cooperative personnel closely observe the horizontality of the level bubbles on the first and second horizontal ends of the column and the continuous contact with the column, and communicate with the hydraulic pile driver operator about the direction that needs to be adjusted. Reduce the process of constantly re-measuring the driving depth with a level meter, and control the verticality by naked eye observation.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
