Abstract

The invention discloses a mixed spraying system special for a TBM. The system comprises a rear matched trolley, a concrete pumping system, an additive system, an air compressor system connected with a TBM air supply system, a power source control system connected with a TBM hydraulic pump station and a wet spraying mechanical hand connected with a walking cart, the concrete pumping system, the additive system and the air compressor system are installed on the rear matched trolley, the power source control system is connected with the concrete pumping system and the wet spraying mechanical hand, and the wet spraying mechanical hand is connected with the concrete pumping system, the additive system and the air compressor system. According to the mixed spraying system, the requirement for TBM space is lowered; the power source control system and the TBM hydraulic pump station are fused, the air compressor system and the TBM air supply system are fused, the whole machine is high in TBM integration degree, and optimization of the system performance is achieved; meanwhile, the cost is greatly lowered, and the TBM equipment competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of design and construction of a full-face rock tunnel boring machine, in particular to an automatic grouting system used for TBM construction support. Background technique [0002] The full-face rock tunnel boring machine is referred to as TBM, and the open TBM and its subsequent supporting systems are generally designed and arranged with a concrete shotcrete system, so as to realize the shotcrete support operation of the tunnel while the TBM is excavating. The working principle of concrete spraying is to transport the pre-mixed concrete to the nozzle of the wet spraying machine through the pumping system, form a bundle after being mixed with accelerator, and spray it to the sprayed surface under the action of high-pressure gas to accelerate the setting. The agent makes the concrete set and harden quickly, thus forming a concrete support layer. [0003] At present, the mixed injection system of domestic TBM...
