Embodiment Construction

[0026] see Figure 1 to Figure 5 The tunnel lining solar energy-ground source heat pump combined heat storage heating system includes a solar collector 13 , a ground source heat pump heat exchanger 2 , a ground source heat pump device 5 and a heat supply pipeline 8 . The solar energy-ground source heat pump combined thermal storage heating system for tunnel lining in cold regions can be implemented in the following steps:

[0027] 1. After the blasting and excavation of the tunnel is completed, a bolt hole 12 is drilled into the surrounding rock 1, and the ground source heat pump heat exchanger 2 is directly installed in the hollow bolt in the bolt hole 12;

[0028] 2. Connect the inlet and outlet of the ground source heat pump heat exchanger 2 in each bolt hole 12 with the first water outlet main pipe 3 and the first water inlet main pipe 4 in parallel and connect with the ground source heat pump equipment 5 to obtain heat The ports are connected into a heat-taking loop;

Abstract

The invention discloses a cold region tunnel lining solar energy and ground source heat pump combined heat storage heating system and a cold region tunnel lining solar energy and ground source heat pump combined heat storage heating method. The cold region tunnel lining solar energy and ground source heat pump combined heat storage heating system comprises a solar energy heat collector, a ground source heat pump heat exchanger, a ground source heat pump device and a heat supplying pipeline, wherein the ground source heat pump heat exchanger is connected with the solar energy heat collector to form a heat storage ring road in surrounding rock at the middle portion of a tunnel and connected with the ground source heat pump device to form a heat taking ring road in the surrounding rock at the middle portion of the tunnel, and the heat supplying pipeline is connected with the solar energy heat collector to form a heat storage ring road in surrounding rock in the entrance section of the tunnel and connected with the ground source heat pump device to form a heat supplying ring road in tunnel lining in the entrance section of the tunnel. The ground source heat pump heat exchanger is installed in a hollow anchor rod inside the surrounding rock in the middle portion of the tunnel, and thereby underground drilling needed by a buried pipe of the traditional ground source heat pump is substituted, occupied area is not needed, initial investment is saved, solar energy in summer is stored in the surrounding rock in the tunnel around the heat exchanger and the heat supplying pipeline so as to be used for preventing the tunnel from being frozen, and the solar energy can be used of all season.

Description

technical field [0001] The invention relates to antifreeze and heat preservation for tunnels in cold regions, in particular to a solar energy-ground source heat pump combined heat storage heating system for lining tunnels in cold regions. Background technique [0002] Judging from the use of railway and highway tunnels in cold regions, the phenomenon of frost damage is very serious, causing major traffic accidents and leading to the scrapping of the main structure of the tunnel, etc. Tunnels in cold regions urgently need to solve the problem of freezing damage at the entrance section. My authorized invention patent "tunnel opening section lining heating system (ZL200910196239.X)" uses the heat exchange tube arranged between the primary lining and the secondary lining of the deep buried section in the middle of the tunnel to absorb the geothermal energy of the surrounding rock, After the source heat pump equipment is upgraded, the energy-saving technology for heating the lini...
