Description

Tunnel drainage pipe self-adaptive crystallization blockage dredging and silting suction device

technical field

The invention belongs to the technical field of tunnel drainage pipe crystallization treatment equipment or devices, and in particular relates to a tunnel drainage pipe self-adaptive crystallization blockage dredging and silt suction device.

Background technique

In areas rich in groundwater, shotcrete has poor impermeability and is continuously eroded by erosive groundwater at the initial stage of construction. Groundwater is easy to penetrate the shotcrete and invade the interior of the tunnel, affecting the durability of the tunnel structure and the construction process. In shotcrete, the gel material is continuously hydrated to produce hydration products such as calcium hydroxide and calcium silicate hydrate. When the groundwater rich in corrosive ions passes through the concrete, the calcium ions in the concrete are dissolved, making the calcium ions As the erosive fluid flows into the tunnel drainage system, it accelerates the crystallization and clogging of the drainage system. This process is called the "calcium dissolution crystallization" phenomenon of tunnel shotcrete.

The calcium dissolution effect of shotcrete makes the underground aqueous solution flowing into the drainage system rich in precipitated substances such as calcium ions, which are easy to combine with bicarbonate or carbonate ions to form calcium carbonate crystals that adhere to the surface of the drainage pipes, resulting in blockage of the drainage pipes over time. . The blockage of the drainage system prevents the groundwater behind the lining from being drained in time, and then acts on the outside of the support structure and the bottom of the road surface in the form of pressure, causing the lining and the road surface to bear additional water pressure, resulting in a large number of tunnels being destroyed in a short time after completion. Lining cracks, water leakage, and road surface water leakage have occurred, seriously endangering the safety of tunnel operation.

Due to the complex internal conditions of the tunnel drainage system, and during the tunnel construction period, due to construction reasons, the drainage pipes are often crushed, causing pipe rupture, deformation, corrosion and other diseases. These will cause the internal size of the pipeline to deviate from the originally designed size. The existing crystallization treatment device cannot realize the treatment work under different pipe diameters due to its fixed size. For example, the patent number is: ZL201920397536.X, and the invention title is "A Tunnel Crystal Dredging Device"; Crystal cleaning devices with different pipe diameters.
