[0003] The patent with the patent announcement number CN207619995U relates to a high-pressure rotary jet pile equipment for the construction of a cofferdam anti-seepage wall, including a rotary jet pipe and a nozzle mechanism, the upper end of the nozzle mechanism is fixedly connected to the rotary jet pipe, the rotary jet pipe and the nozzle mechanism are both arranged vertically, the nozzle mechanism includes a spray pipe for conveying cement slurry, an air jet pipe for conveying high-pressure gas, a water spray pipe for conveying high-pressure water, and a spray pipe for conveying an accelerator, and the spray pipe and the rotary jet pipe are coaxially arranged. The patent has a simple structure and a reasonable design. By adding a spray pipe in the rotary jet pipe, the accelerator is mixed with the cement slurry synchronously during the cement slurry conveying process, which effectively shortens the seepage time of the mixed cement slurry, can meet the requirements for water environment protection, avoid the mixed cement slurry being carried away by the water flow before solidification, block the water flow channel and cavity inside the constructed cofferdam, and effectively ensure the slurry return phenomenon, thereby achieving the purpose of consolidation and anti-seepage.

[0004] In the above patent, a spray pipe is added inside the rotary jet pipe, and the quick-setting agent is mixed with the cement slurry synchronously during the cement slurry transportation process, thereby effectively shortening the seepage time of the mixed cement slurry, meeting the requirements for water environment protection, avoiding the mixed cement slurry from being carried away by the water flow before solidification, and blocking the water flow channels and cavities inside the constructed cofferdam, while effectively ensuring the slurry return phenomenon, thereby achieving the purpose of consolidation and anti-seepage. However, it is difficult to position and correct the position of the high-pressure jet connecting rod. At the same time, it is difficult to detect whether the rotary jet position is offset during high-pressure rotary jet pile construction. The construction quality of high-pressure rotary jet piles directly depends on the position of the high-pressure jet connecting rod and the jet angle. If the position of the high-pressure jet connecting rod cannot be ensured, the jetting process will be uneven, thereby affecting the hole-forming effect and stability of the pile body.

[0015] The present invention provides a detection device for high-pressure jet grouting pile equipment for water conservancy projects. It has the following beneficial effects: (1) The invention can perform high-pressure rotary spraying through the support plate, the driving device and the high-pressure spraying connecting rod. The laser displacement sensor can detect the position deviation of the high-pressure spraying connecting rod to avoid the displacement of the high-pressure spraying connecting rod affecting the effect of the rotary spraying.

[0016] (2) In the present invention, the high-pressure injection connecting rod is positioned and corrected by the reciprocating movement of the T-shaped plate to ensure that the high-pressure injection connecting rod moves downward at a vertical angle. The verticality of the high-pressure injection connecting rod directly affects the accuracy of the injection hole and the quality of the pile body. The reciprocating movement of the T-shaped plate can correct the position of the high-pressure injection connecting rod to ensure that it does not deviate in the vertical direction, thereby avoiding the high-pressure injection connecting rod from being deflected during the rotary spraying process, further ensuring that the cement slurry is injected into the soil along a predetermined path. The scraper ring contacts the high-pressure injection connecting rod to scrape foreign matter on the surface of the high-pressure injection connecting rod. If mud or other foreign matter accumulates on the surface of the high-pressure injection connecting rod, the injection effect of the high-pressure injection connecting rod will be poor. The scraper ring can continuously scrape these foreign matter to avoid the accumulation of foreign matter and maintain the injection effect of the high-pressure injection connecting rod.

[0017] (3) In the present invention, the rubber block is deformed by the compression of the rheology control agent entering the conduit. The rubber block is deformed and contacts the seal of the conduit. After the seal of the conduit is released, part of the rheology control agent on the left side of the square frame enters the storage barrel through the conduit and mixes with the cement slurry in the storage barrel. The rheology control agent helps to improve the stability of the cement slurry, thereby ensuring that the cement slurry can smoothly enter the pores and cracks in the soil, further enhancing the stability and strength of the pile body. In addition, the rheology properties of the cement slurry can be accurately adjusted by quantitatively adding the rheology control agent, ensuring the appropriate viscosity and fluidity of the slurry, thereby avoiding a decrease in injection efficiency due to overly thick or overly thin slurry.

[0018] (4) In the present invention, the gear rotates clockwise to drive the stirring rod to rotate clockwise, and the clockwise rotation of the stirring rod drives the curved rod to rotate. The rotation of the curved rod breaks up the material put into the storage barrel. The rotation of the curved rod can effectively break up the lumps or sticky substances in the material, improve the fluidity of the material, and ensure that the material can flow into the storage barrel evenly, thereby ensuring that the cement slurry in the construction process can achieve the expected strength and density. The vibration of the protrusion drives the stirring rod to vibrate, and the vibration of the stirring rod drives the curved rod to resonate together. The resonance of the curved rod makes the lumps in the material more effectively broken up, further improving the effect of the curved rod in breaking up the agglomerated materials.
