Description
Technical field:
the invention relates to a detection tube for maintenance detection of foundation piles in highway engineering, and belongs to the technical field of foundation pile detection equipment.
The background technology is as follows:
and (3) constructing the bridge or roadbed slide-resistant pile, and detecting the construction quality of the foundation pile according to the relevant regulations of the transportation department so as to ensure that the bridge and roadbed slope can be operated safely after the vehicle is passed. The existing foundation pile detection method is widely applied in the construction stage of the foundation pile of the highway engineering, and has the advantages of quick detection, low cost, good effect and light equipment. After the foundation pile construction is completed, the existing foundation pile construction stage detection technology is used for foundation pile detection work by taking the pile top as a detection working surface before the upper structure is not constructed. Therefore, for foundation piles which are already in the upper structure or in the running process, the existing equipment cannot finish maintenance quality detection in the running process of the foundation piles due to the lack of working surfaces of pile tops. On the other hand, various types of lesions such as stress damage, steel bar corrosion, concrete aging and the like can appear on the foundation of the foundation pile in service due to geological disasters, stress changes, fluid erosion, earthquakes, impacts and the like in the running process of the foundation pile in service. It is necessary to find and treat such lesions in time and to evaluate and eliminate hidden trouble in-service foundation pile integrity in time. In addition, the foundation pile of the highway engineering part is damaged by external forces such as water wave impact, groundwater erosion, ship impact and the like, and the foundation pile concrete is accelerated to age in the use process, so that the maintenance detection and evaluation of the foundation pile diseases of the highway engineering are more important.
At present, the methods for curing and detecting foundation piles at home and abroad mainly comprise the following steps:
1. a side digging method. Excavating and detecting the side face of the foundation pile to be detected by adopting machinery or manpower;
2. a dual speed process. For foundation piles under existing structures, elastic waves can generate extremely complex reflection and transmission at the structure interface or pile top, and not only downstream waves but also upstream waves are generated. In the foundation pile low strain detection technology, the uplink stress wave capable of reflecting pile body impedance or soil resistance change information is the most important. For foundation pile integrity detection under existing structures, a method for acquiring an uplink stress wave is desired. In order to effectively extract the uplink stress wave, M.Johnson in 1996 proposed to arrange two acceleration sensors along the pile body, and simultaneously measure a two-point acceleration time domain curve, so that the purposes of testing the wave speed of the pile body and acquiring the effective uplink wave of the foundation pile part can be achieved;
3. transverse wave method (torsional wave method). For the problem that the one-dimensional longitudinal wave assumption is not established in the large-diameter pile, a transverse wave detection technology, also called a torsional shear wave method or a bending wave method (BendingWaves } BW), is proposed. The method generates a torsional wave on the pile side through transverse excitation, and the torsional wave is recorded and analyzed by a sensor arranged on the same side of the pile body;
4. and (5) a super-seismic wave method. The method has the comprehensive characteristics of a reflected wave method and a parallel vibration measurement method. Multiple receivers were placed along the outside of the shaft (generally collinear equidistant) in the test (fig. 3). And knocking the pile top or the pile body, and measuring a time-dependent curve of particle velocity. Repeating the above process to obtain the arrival time diagram of the direct wave and the reflected wave, wherein the intersection point of the peak point connecting line reached by the direct wave and the peak point connecting line of the reflected wave is the pile bottom or the defect point;
5. integrated technology based on radar method. The comprehensive detection technology of the foundation of the in-service bridge foundation comprises nondestructive detection equipment and detection technology of the foundation of the in-service bridge foundation by a radar method and a wave method (a reflected wave method and a side hole transmission wave method). On the basis of firstly using a reflected wave method to rapidly check whether the in-service bridge foundation pile has diseases or defects, the diseases or defects are accurately positioned and analyzed by a radar method or a side hole method.
The existing method has the defects that:
1. the detection depth is limited. For example, in the detection process, the side digging method is difficult to implement, low in detection efficiency, high in cost and high in limitation due to complex environmental conditions of the foundation of the in-service bridge foundation and deep embedding, and is difficult to popularize and apply in foundation pile maintenance detection;
2. the detection needs to be performed on a specific work surface. For example, a dual-speed method and a super-seismic wave method are adopted, and the pile body is required to have a certain exposed length for installing a sensor during detection. However, the foundation piles with the special working surface are not much in actual detection work, so that the foundation piles are difficult to popularize and apply in foundation pile maintenance detection;
3. the detection data acquisition stability is poor. For example, the dual-speed method and the transverse wave method (torsional wave method) are greatly influenced by external factors (sensor installation, detection surface selection, excitation equipment selection and the like) during detection, detection data with good stability cannot be obtained, and great influence is brought to the judgment of a detection result, so that the method is difficult to popularize and apply in foundation pile maintenance detection;
4. the special detection equipment is high in cost. For example, the geological radar antenna used in detection is special detection equipment based on the comprehensive technology of radar method, and the cost of a single antenna is as high as 80 ten thousand RMB. The high equipment cost is difficult to popularize and apply in foundation pile maintenance and detection;
5. the matching operation cost before detection is high and difficult. If the comprehensive technology based on the radar method is adopted, a detection channel needs to be drilled on the foundation pile accessory to be detected before detection, a middle-sized address drilling machine is required to be used for drilling the detection channel, the mountain area drilling machine is difficult to carry and erect, the cost is high, the efficiency is low, the limitation is large, and the foundation pile detection method is difficult to popularize and apply in foundation pile maintenance detection;
6. foundation piles located under water cannot be detected. None of the above 5 methods can perform maintenance and inspection of foundation piles positioned under water. The foundation piles of the highway engineering are positioned in the water areas such as sea, lakeside, river and the like, and the foundation piles are damaged by external forces such as water wave impact, groundwater erosion, ship impact and the like, so that the condition of accelerated aging of foundation pile concrete can occur in the use process, and the maintenance detection and evaluation of the diseases of the underwater foundation piles are more important. The prior art cannot perform maintenance detection on the underwater foundation piles.
The invention comprises the following steps:
the invention aims to overcome the defects of the existing foundation pile maintenance detection device and provide a detection tube for highway engineering foundation pile maintenance detection.

C. after the pipe orifice joint component and the pipe body component are installed, the bottom of the single-sided thread protection rubber sleeve (5) is inserted into the top of the first section of high-strength PVC pipe (6).
