Description

Technical Field

[0001] The utility model relates to the technical field of tunnel duct grouting, in particular to an integrated machine for detecting duct grouting data in a tunnel engineering project. Background Art

[0002] Pore ​​grouting is widely used in post-tensioned prestressed bridges, curtain grouting, anchor grouting, and the filling and repair of gaps and voids. It plays a key and important role in projects such as bridges, railways, highways and high-rise buildings, providing stable support and reliable reinforcement for these structures. Prestressed pore grouting, referred to as prestressed grouting, is a special building material used to repair and reinforce building structures. Its main components include cement, quartz sand, admixtures, etc., which are mixed and stirred to form a uniform and fine slurry. The special feature of this slurry is that it can penetrate and fill the pores inside the concrete, improving the strength and durability of the concrete. Prestressed pore grouting is widely used in the repair and reinforcement of concrete structures. When there are problems such as cracks, voids, and holes in the concrete, the prestressed grouting can reinforce the defective parts in the structure by penetration and filling, thereby improving the overall bearing capacity and stability.

[0003] Tunnels are projects that are often affected by geological conditions and the water and soil environment, and have high requirements for the durability of concrete structures. Prestressed hole grouting materials can be used for structural maintenance inside tunnels to improve the overall stability and safety of tunnels. When grouting the holes in the tunnel, due to the presence of embedded parts in the holes, in order not to damage the embedded parts during grouting, leakage will occur from the position where the embedded parts extend into the holes, resulting in insufficient grouting pressure in the holes, which will affect the stability and durability of the tunnel structure. At the same time, after the grouting end of the hole is sealed, it is difficult to analyze the pressure in the hole during the grouting process. If the grouting pressure exceeds the safety range of the structural design, it may cause damage to the tunnel or structure. For this reason, a tunnel engineering hole grouting data detection integrated machine is proposed to solve the above problems. Utility Model Content
