Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a bridge cast-in-place pile drilling positioning device. Background Art

[0002] The quality of foundation construction is a key factor in ensuring the safety of the overall structure of the bridge. Bored piles are effective in ensuring foundation stability and improving foundation bearing capacity, and are one of the commonly used technologies in bridge foundation reinforcement. In order to ensure the quality of construction, it is necessary to implement refined management during the construction period and carry out quality inspection in a timely manner after the construction is completed, which has a positive effect on the overall construction quality assurance of bridge projects. Due to the large number of bridges in my country, when the construction methods of bridge pile foundations are sunk into the soil are different, the machines and construction processes used in the construction are also different. Therefore, in the construction, we must pay full attention to the scientific application of bored pile technology, so that the quality of bridge pile foundation construction can be guaranteed and the normal operation of the bridge can be ensured. The existing technology will use a guide sleeve structure for guiding the drill rod to limit the deflection of the drill rod. However, when the drill rod deflects, it will cause rigid internal stress with the guide sleeve. When the drill rod deviates at a large angle and is not discovered, it is very easy to cause excessive wear of the drill rod and the guide sleeve, which greatly affects the service life of the drill rod. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a drilling positioning device for cast-in-place piles of bridges.

[0004] The utility model provides a bridge cast-in-place pile drilling positioning device comprising:

[0005] Positioning sleeve, and

[0006] An inner liner is elastically arranged in the positioning sleeve, and an annular elastic pleated airbag is fixedly embedded on the outer wall of the inner liner, and the outer wall of the annular elastic pleated airbag is fixedly embedded in the annular cavity opened in the inner wall of the positioning sleeve;

[0007] The annular elastic pleated airbag is provided with interconnected elastic pleated telescopic airbag columns;

[0008] The positioning sleeve is also equipped with a prompt component, and the prompt component includes a mounting frame, the mounting frame is fixedly mounted on the outer tube wall of the positioning sleeve, and a pressure sensor and a voice alarm are installed on the mounting frame, and the pressure sensor is arranged opposite to the elastic pleated telescopic airbag column.

[0009] Preferably, the annular elastic pleated airbag is divided into a plurality of air storage chambers by a plurality of annularly distributed elastic segmented bag portions, and an elastic pleated telescopic airbag column interconnected with the air storage chamber is installed on the outer bag wall of each air storage chamber, and the elastic pleated telescopic airbag column passes through the through hole opened in the positioning sleeve and extends out of the positioning sleeve.

[0010] Preferably, a pressing disk for abutting against the pressure sensor is fixedly mounted on the positioning sleeve.

[0011] Preferably, the prompt components are provided in several groups, and the prompt components correspond one-to-one to the elastic pleated telescopic airbag columns respectively.

[0012] Preferably, an inserting tough portion is provided at the bottom of the positioning sleeve.

[0013] Preferably, a fitting plate for fitting with the ground is fixedly mounted on the positioning sleeve, and a plurality of mounting holes are formed on the fitting plate.

[0014] Compared with the related art, the bridge cast-in-place pile drilling positioning device provided by the utility model has the following beneficial effects:

[0015] When the drill rod is deflected to one side, the drill rod is pressed against the inner tube on that side, so the elastic corrugated telescopic airbag column is expanded, which can relieve the internal stress between the drill rod and the inner tube when the drill rod is deflected; when the expanded elastic corrugated telescopic airbag column squeezes the pressure sensor through the pressing plate, the voice alarm gives a voice alarm, so that the staff can quickly understand the situation in time and take emergency measures, avoiding the hidden danger of excessive wear of the drill rod and the inner tube caused by the drill rod deflecting at a large angle without being discovered; at the same time, the staff can also be informed of the deviation direction of the drill rod of the drilling equipment through the early warning of the voice alarms in different directions, thereby improving the efficiency of the staff in correcting the drill rod.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] See also Figures 1 to 6 The embodiment of the utility model provides a bridge bored pile drilling positioning device, which includes: a positioning sleeve 1, an annular elastic pleated airbag 2, an inner tube 3 and a prompt component 4.

[0026] In the embodiments of the present invention, please refer to Figure 1 , 2 , Figure 3 , Figure 4 and Figure 5 An inner tube 3 is elastically provided in the positioning sleeve 1, specifically, an annular elastic pleated airbag 2 is fixedly embedded on the outer tube wall of the inner tube 3, and the outer tube wall of the annular elastic pleated airbag 2 is fixedly embedded in the annular cavity 1a opened in the inner tube wall of the positioning sleeve 1, and the annular elastic pleated airbag 2 is installed with elastic pleated telescopic airbag columns 22 that are interconnected. The annular elastic pleated airbag 2 is divided into multiple air storage chambers 2a by multiple annularly distributed elastic dividing bag parts 21, and each of the air storage chambers 2a is installed with an elastic pleated telescopic airbag column 22 that is interconnected with the air storage chamber 2a on the outer ring wall, and the elastic pleated telescopic airbag column 22 passes through the through hole 1b opened in the positioning sleeve 1 and extends out of the positioning sleeve 1.

[0027] It should be noted that: the inner tube 3 in the positioning sleeve 1 is used to guide the drill rod of the drilling equipment to ensure the accuracy of the drilling position, and when the drill rod deflects to one side, the drill rod abuts against the inner tube 3 on that side, thereby driving the inner tube 3 to also abut against the air storage chamber 2a in the annular elastic pleated airbag 2 in the corresponding orientation, and after the air storage chamber 2a is compressed, the gas in the air storage chamber 2a is driven to flow into the corresponding elastic pleated telescopic airbag column 22, so that the elastic pleated telescopic airbag column 22 expands, which can relieve the internal stress between the drill rod and the inner tube 3 when the drill rod deflects;

[0028] Among them, the bottom of the positioning sleeve 1 is provided with an insertion tough part 11, and the positioning sleeve 1 is fixedly provided with a fitting plate 12 for fitting with the ground, and the fitting plate 12 is provided with a plurality of mounting holes, so as to facilitate the insertion of the positioning sleeve 1 into the soil layer at the drilling position of the bridge bored pile, until the fitting plate 12 overlaps the ground and then uses ground spikes to penetrate the mounting holes on the fitting plate 12 for fastening.

[0029] In the embodiments of the present invention, please refer to Figure 1 and Figure 6 A prompt component 4 is also installed on the positioning sleeve 1, and the prompt component 4 is provided with several groups, and the prompt component 4 corresponds to the elastic pleated telescopic airbag column 22 one by one, and the prompt component 4 includes a mounting frame 41, and the mounting frame 41 is fixedly mounted on the outer tube wall of the positioning sleeve 1, and a pressure sensor 42 and a voice alarm 43 are installed on the mounting frame 41, the pressure sensor 42 is arranged opposite to the elastic pleated telescopic airbag column 22, and a pressing disk 221 for abutting the pressure sensor 42 is fixedly installed on the positioning sleeve 1.

[0030] It should be noted that: a warning value is pre-set in the pressure sensor 42. When the inflated elastic pleated telescopic airbag column 22 squeezes the pressure sensor 42 through the pressing plate 221, and the pressure value received by the pressure sensor 42 is greater than the warning value, the voice alarm 43 will issue a voice alarm, so that the staff can quickly understand the situation in time and take emergency measures to avoid the hidden danger of excessive wear of the drill rod and the inner tube 3 caused by the large deviation of the drill rod without being discovered. At the same time, the warning of the voice alarm 43 in different directions can also make the staff know the direction of the drill rod deviation of the drilling equipment, thereby improving the efficiency of the staff in correcting the drill rod.

[0031] The working principle of the bridge cast-in-place pile drilling positioning device provided by the utility model is as follows:

[0032] The inner tube 3 in the positioning sleeve 1 is used to guide the drill rod of the drilling equipment to ensure the accuracy of the drilling position. When the drill rod deflects to one side, the drill rod abuts against the inner tube 3 on that side, thereby driving the inner tube 3 to abut against the air storage chamber 2a in the annular elastic pleated airbag 2 in the corresponding orientation. After the air storage chamber 2a is compressed, the gas in the air storage chamber 2a is driven to flow into the corresponding elastic pleated telescopic airbag column 22. Therefore, the elastic pleated telescopic airbag column 22 expands, which can relieve the internal stress between the drill rod and the inner tube 3 when the drill rod deflects, and a pre-set pressure sensor 42 is provided in advance. Warning value, when the inflated elastic pleated telescopic airbag column 22 squeezes the pressure sensor 42 through the pressing plate 221, and the pressure value received by the pressure sensor 42 is greater than the warning value, the voice alarm 43 will give a voice alarm, so that the staff can quickly understand the situation in time and take emergency measures, avoiding the hidden danger of excessive wear of the drill rod and the inner tube 3 caused by the large deviation of the drill rod without being discovered. At the same time, the staff can also be informed of the deviation direction of the drill rod of the drilling equipment through the warning of the voice alarm 43 in different directions, thereby improving the efficiency of the staff in correcting the drill rod.
