Embodiment Construction

[0019] In order to make the technical means, creative features, functions and effects realized by the present invention easy to understand, the present invention is further elaborated below.

[0020] The installation and construction method of the capillary heat exchanger at the front end of the subway tunnel heat pump includes the following steps:

[0021] (1) Requirements before installation and construction of heat exchanger

[0022] The construction of the subway waterproof layer has been completed and meets the quality acceptance standards for waterproof construction.

[0023] (2) Capillary heat exchanger installation

[0024] Preparations before installation:

[0025] 1. Before the equipment is installed, draw the installation reference line and positioning reference mark on the waterproof layer according to the requirements of the design drawings and technical documents.

[0026] 2. Check the position of the nozzle of the equipment again, and make a mark for installa...

Abstract

The invention aims to a construction method for mounting a front-end capillary tube heat exchanger of a subway tunnel heat pump. The construction method comprises the following steps: (1) checking whether a waterproof layer is damaged and whether the waterproof layer meets the mounting standard; (2) determining a laying position of a capillary tube network; (3) fixing a tube clamp and a capillary tube module; (4) enabling a water supplying and returning tube of the capillary tube to be in hot-melt connection with a water collection main pipe; (5) carrying out bulge test of the capillary tube; and (6) hiding the capillary tube and carrying out structure construction of a surrounding rock secondary lining, a water retaining plate and a primary lining by construction units. Compared with the prior art, through the process steps, the situation that the capillary tube is used as a front-end heat exchanger and is constructed in subways is solved; the method is simple, and is convenient to implement, rapid in construction progress, high in possibility of guaranteeing construction quality and excellent in construction effect.

Description

technical field [0001] The invention relates to a construction method for installing a capillary tube heat exchanger at the front end of a subway tunnel heat pump. Background technique [0002] With the aggravation of problems such as urban traffic congestion, environmental pollution and energy shortage, more and more subways are used. The subway is a relatively closed underground building. The tunnels and stations are covered by several meters to tens of meters of rock and soil, and are basically isolated from the outside world. They can only exchange air with the outside world through the entrances and exits of the stations and limited air shafts. The location of the tunnel and the station is just within the scope of the development and utilization of shallow geothermal energy, and the surrounding rock and soil contain abundant low-level thermal energy. During operation, the subway train traction system, station lighting system, equipment and personnel to maintain the ope...
