Description

Technical Field

[0001] The invention relates to the technical field of deep pipeline detection, in particular to a deep pipeline detection device in a soft soil area and a pile foundation construction method. Background Art

[0002] With the growth of urban population and economic development in my country, and the continuous expansion of urban space, more and more cities have started the process of rapid urban road transformation. In the process of transformation, existing underground pipelines often affect construction, and relocation lags behind. Inevitably, there is the problem of cross-construction of pipelines and foundation pit retaining, which will have a great impact on the construction of foundation pit retaining.

[0003] At present, the conventional underground pipeline detection methods are mainly electromagnetic method and ground penetrating radar method. However, the detection depth of these two methods is limited, generally not exceeding 6m. Static penetration equipment can perform more accurate measurements of deeper locations, but common static penetration equipment generally uses plug-in rods to fix the support frame to the ground, and then the penetration probe is lowered to complete the detection. When a part is detected, it is necessary to first release the fixed installation of the support frame, and then remove multiple plug-in rods, change a position, re-fix and repeat the above steps before the detection can be carried out. As a result, the detection of multiple positions in the same detection area requires multiple dismantling and fixing, which is time-consuming. In addition, when detecting soft soil areas, in order to place Stable, the general support frame has a large area, resulting in the entire equipment taking up a large space when not in use, which is inconvenient for transportation and storage, and the soft soil area may not be a horizontal plane, causing the static detection device to tilt, and there is no structure to detect the moving direction of the probing probe, resulting in the deviation of the downward direction of the probing probe during the downward pressure process. These factors will affect the accuracy of static detection, and because the probing probe is a pointed head, it is not only easy to slide when detecting the pipeline, but also easy to damage the pipeline. Therefore, it is of great significance to study a new deep pipeline detection equipment and pile foundation construction method in soft soil areas to solve the above problems. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0006] Therefore, the technical problem to be solved by the present invention is that the common static penetration equipment can only detect one point at a time, resulting in the need to dismantle and fix multiple times for detecting multiple positions in the same detection area. In addition, the entire equipment occupies a large space when not in use, which is inconvenient for transportation and storage. In addition, the static detection device is prone to tilt, and the downward pressing direction of the penetration probe may deviate during the downward pressing process, affecting the accuracy of the static detection. In addition, since the penetration probe has a pointed tip, it is not only easy to slip when detecting the pipeline, but also easy to damage the pipeline.

[0019] The plate frame, the horizontal platform and the bottom plate are each provided with two detection ports.

[0020] A method for using a deep pipeline detection device in a soft soil area and a pile foundation construction method, comprising the following steps:

[0021] S1. Construction preparation

[0022] In the pre-construction preparation stage, conduct detailed investigation and excavation of existing pipelines on site and compare them with existing pipeline maps to understand the general direction, route and buried depth of pipelines, and form complete pipeline investigation data with guiding significance for on-site construction;

[0023] S2. Geophysical Exploration

[0024] For valve attachments, the method of direct well opening measurement is adopted;

[0025] S3. Precision Geophysical Exploration

[0026] The reaction anchor is lowered, and the gear plate and the gear are controlled by the first bidirectional electric hydraulic rod. The gear drives the rotating shaft to rotate, and the rotating shaft drives the plate frame to flip downward through the rotating member, so that the plate frame is flush with the bottom plate after flipping, and then the assembly parts are assembled on the reaction anchor;

[0027] Then, the connecting pipe is opened by turning the control valve. At this time, the horizontality of the horizontal platform is adjusted according to the needs. The horizontal platform adjusts the angle through the universal joint so that the horizontal platform drives the second piston rod to move. Since the piston cylinder and the connecting pipe store liquid, the other second piston rod is driven to move through the hydraulic pressure. The verticality of the probe is observed through the level meter. After adjustment, the control valve is turned to close the pipeline of the connecting pipe.

[0028] Secondly, the sounding probe is penetrated downward into the soil layer through the detection device. During the penetration process, the sounding probe passes through the roller. When the sounding probe is penetrated crookedly, the sounding probe squeezes the roller to move. Since the piston cylinders are connected through the annular tube, the roller drives the first piston rod to move, and the air pressure enters the transparent cylinder through the annular tube, so that the air pressure drives the sealing plug to move, and the sealing plug is separated from the switch. At this time, the switch gives an alarm reminder through the alarm light, and then the sounding probe is adjusted to keep the sounding probe vertically penetrated into the soil layer. During the penetration process, pay attention to the changes in the readings of the detection device. When the cone tip data of the sounding probe suddenly becomes larger and the penetration degree is zero, the penetration is stopped immediately and marked.

[0029] Then the bracket is retracted by the second bidirectional electric hydraulic rod, so that the anti-slip plate is separated from the first guide rail. At this time, the detection device is transferred to the plate frame by the rolling of the walking wheel group, and then the detection operation is performed again;

[0030] S4. Lofting of hole position

[0031] According to the detection results, the total station is used to lay out the positions of the pile holes above the pipeline and on both sides, and the rotary drilling rig is used to drill holes;

[0032] S5. Pile foundation opening

[0033] Use a rotary drilling rig to drill holes;

[0034] S6. Manual drilling

[0035] Manually use water drilling equipment to drill holes along the outer edge of the retaining pile;

[0036] S7, continue drilling pile foundation construction

[0037] When it is confirmed that there are no underground pipelines, the rotary drilling rig will continue to carry out hole-forming construction.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The deep pipeline detection equipment and pile foundation construction method in soft soil areas are arranged with multiple sets of second piston rods below the horizontal platform to make the horizontal platform adjustable. The second piston rods can be adjusted by hydraulic pressure by connecting the piston cylinder and the connecting pipe, and the horizontality of the horizontal platform can be achieved by cooperating with the level meter to keep the verticality of the touch probe, which is conducive to accurate detection. At the same time, when the touch probe is downward, if the touch probe is deflected, the touch probe can be moved by squeezing the first piston rod by the roller, and then the sealing plug can be controlled to move by air pressure, and the switch is separated from the touch rod, so that the alarm light can give an alarm reminder. In this way, the vertical direction of the touch probe can be monitored during the detection process to avoid the deflection affecting the accuracy of the touch probe.

[0040] 2. The deep pipeline detection equipment and pile foundation construction method in soft soil areas control the transmission of the toothed plate and the gear through the first bidirectional electric hydraulic rod, so that the gear drives the rotating shaft and the rotating member to rotate, and the rotating member drives the plate frame to flip, so that the plate frame flips and keeps it level with the bottom plate, so that the second guide rail corresponds to the first guide rail. At this time, the walking wheel group moves from the first guide rail to the second guide rail, and controls the movement of the bracket through the second bidirectional electric hydraulic rod, so that the anti-slip plate is pressed against the second guide rail, so that the position of the detection device can be locked. This method makes the detection position adjustable, which is convenient for realizing multi-point detection and improves the convenience of detection operation. Similarly, the plate frame can be flipped upward to keep it vertical, so that it can play a role in rapid storage, and also plays a certain role in protecting the detection device;

[0041] 3. The deep pipeline detection equipment and pile foundation construction method in soft soil areas drive the support assembly to flip through the driving assembly, so that the support assembly remains level with the bottom plate after flipping. This method can increase the contact area with the ground and improve the overall stability. At the same time, it can effectively ensure the verticality of the probe when cooperating with the adjustment assembly. When the probe is operated by the detection device to detect, the collapse and skew problems in the operation process can be effectively reduced, and the accuracy of detection can be further improved to avoid the need for adjustment due to skewness and extend the detection progress.

[0042] 4. The deep pipeline detection equipment and pile foundation construction method in soft soil areas, by changing the cone tip of the sounding probe into a customized flat head shape of plastic material, not only increases the contact area between the cone tip of the probe and the pipeline surface, reduces the local pressure on the pipeline during penetration, but also reduces the probability of mutual slippage due to the cone tip touching the pipeline area being too small. Secondly, under the premise of protecting underground pipelines, this device adopts precise detection and pile foundation protection construction to replace the relocation construction of underground pipelines, solves the obstacle clearance problem in bored pile construction, saves a lot of manpower, material resources and construction period, has extremely high economic benefits, and achieves safe construction through precise detection + underground pipeline protection, greatly reduces the risk of underground pipeline damage, prevents environmental damage that may be caused by underground pipeline leakage, reduces the risk of pipeline leakage and environmental pollution, and has certain environmental protection and energy-saving effects.

[0080] B1, B2, and B3 are three abnormal points of penetration. At these locations, their penetration is zero and the 200 value of the penetration probe suddenly rises, which is significantly higher than the normal soil layer. According to the collected data, the 3m below the ground in this area is the original soil layer, and no construction has been done before;

[0081] The plane positions of B1, B2 and B3 are basically located in a straight line and consistent with the direction of the pipeline. The plane positions and burial depths are within the error range of geophysical exploration, which is in line with the characteristics of directional drilling.

[0082] (5) Result generation

[0083] Confirm that B1, B2, and B3 are the precise positioning positions for the penetration of this section of the water supply pipe. The depth error is the measurement error, and the plane position error is the pipe radius 400mm + measurement error. If you need to further improve the plane position accuracy, you only need to increase the number of measuring points based on the existing precise exploration position, perform the same operation steps, repeat steps 1-3, penetrate the pipeline in sections, collect 1-(B1, B2, B3), 2-(B1, B2, B3), 3-(B1, B2, B3)..., enter the three-dimensional coordinates into the database, and generate the results table of this pipeline:

[0084]

[0085] According to the results table, the hole position is staked out, taking into account the verticality deviation of the drilling rig A%, the buried depth of the pipeline H, to ensure the absolute safety of the water supply pipe, and the error of the outer pile foundation construction is safely outside, and the outside dimension X is: X=A%×H×2.

[0086] A method for using a deep pipeline detection device in a soft soil area and a pile foundation construction method, comprising the following steps:

[0087] S1. Construction preparation

[0088] In the pre-construction preparation stage, conduct detailed investigation and excavation of existing pipelines on site and compare them with existing pipeline maps to understand the general direction, route and buried depth of pipelines, and form complete pipeline investigation data with guiding significance for on-site construction;

[0089] S2. Geophysical Exploration

[0090] For valve attachments, the method of direct well opening measurement is adopted;

[0091] S3. Precision Geophysical Exploration

[0092] After the reaction anchor is lowered, the gear plate 3032 and the gear 3033 are controlled by the first bidirectional electric hydraulic rod 3031 to drive, the gear 3033 drives the rotating shaft 3035 to rotate, and the rotating shaft 3035 drives the plate frame 3061 to flip downward through the rotating member 3034, so that the plate frame 3061 is flush with the bottom plate 304 after flipping, and then the assembly part 3063 is assembled on the reaction anchor;

[0093] Then, the connecting pipe 3022 is opened by rotating the control valve 3025. At this time, the horizontality of the horizontal platform 3011 is adjusted according to the demand. The horizontal platform 3011 adjusts the angle through the universal joint 3013, so that the horizontal platform 3011 drives the second piston rod 3024 to move. Since the piston cylinder 3023 and the connecting pipe 3022 store liquid, the other second piston rod 3024 is driven to move through the hydraulic pressure, and the verticality of the probe 200 is observed through the level meter 3014. After adjustment, the control valve 3025 is rotated to close the pipeline of the connecting pipe 3022;

[0094] Secondly, the sounding probe 200 is penetrated downward into the soil layer through the detection device 100. During the penetration process, the sounding probe 200 passes through the roller 30129. When the sounding probe 200 is penetrated crookedly, the sounding probe 200 squeezes the roller 30129 to move. Since the piston cylinder 3023 is connected through the annular tube 30126, the roller 30129 drives the first piston rod 30128 to move, and the air pressure enters the transparent cylinder 30121 through the annular tube 30126, so that the air pressure drives the sealing plug 30122 to move, and the sealing plug 30122 is separated from the switch 30125. At this time, the switch 30125 gives an alarm reminder through the alarm light 30123, and then the sounding probe 200 is adjusted to keep the sounding probe 200 vertically penetrated into the soil layer. During the penetration process, pay attention to the reading changes of the detection device 100. When the cone tip data of the sounding probe 200 suddenly increases and the penetration degree is zero, the penetration is stopped immediately and marked.

[0095] Then, the bracket 3053 is retracted by the second bidirectional electric hydraulic rod 3052, so that the anti-slide plate 3054 is separated from the first guide rail 3056. At this time, the walking wheel group 3055 rolls to transfer the detection device 100 to the plate frame 3061, and then the detection operation is performed again;

[0096] S4. Lofting of hole position

[0097] According to the detection results, the total station is used to lay out the positions of the pile holes above the pipeline and on both sides, and the rotary drilling rig is used to drill holes;

[0098] S5. Pile foundation opening

[0099] A rotary drilling rig is used to drill holes. This method can reduce the disturbance to the underground water pipe. Secondly, to ensure the verticality of the drilling rig, the drilling rig posture is adjusted according to the actual situation on site to ensure that the drilling rig is perpendicular to the ground. When the drilling rig drills H-2 meters, the pile driver is stopped to ensure that there is no water pipe under the drilling rig.

[0100] S6. Manual drilling

[0101] Manually use water drilling equipment to drill holes along the outer edge of the retaining pile. Drill 4 meters to ensure that there are no obstacles below before continuing to use the rotary drilling rig to mechanically drill holes;

[0102] S7, continue drilling pile foundation construction

[0103] When it is confirmed that there are no underground pipelines, the rotary drilling rig will continue to drill holes. If there are pipelines underground, the drilling position will be corrected before continuing construction.
