Insulation and collecting well

Abstract

The invention relates to a heat preservation collecting well, which consists of a turf cover layer, an earth fill layer, heat preservation layers, block stone layers, a water permeable geotextile, and a water outlet. The bottom part of the well, a water outlet end face of a well mouth or the lateral surface of the well wall are provided with the heat preservation layers; two sides or one lateral surface of the well wall is provided with the water permeable geotextile; the block stone layers are stacked in the well; the top part of the well is the earth fill layer; the turf cover layer is above the earth fill layer; and the water outlet is connected with an underground drainage pipe. The heat preservation collecting well uses the water permeable geotextile to replace an inverted filter layer consisting of gravels and block stones of the prior measure to greatly improve construction speed, and uses an extrusion molding polyethylene heat preservation plate to produce double effects of water isolation and heat preservation so that the heat loss in the collecting well is little. The heat preservation collecting well has simple structure, easy and quick construction, and perfect heat preservation effect, is advantageous for drainage, reduces engineering frozen injuries caused by unsmooth drainage in winter, and can be widely applied to underground water collecting and draining systems for projects of highway, railway and the like in cold areas.

Description

technical field The invention relates to a groundwater collection structure in cold regions. Suitable for underground water collection and drainage systems in cold regions. Background technique Most of my country's land area is in the cold region. Road engineering and mine engineering in cold regions all involve the collection and discharge of groundwater. The traditional way of collecting groundwater is to collect groundwater in seepage wells and ponds, and then drain it through hidden pipes and blind ditches. Due to the cold winter climate in cold regions, the water collection structure, hidden pipes, and blind ditch are easily frozen and blocked, resulting in the failure of the entire water collection and drainage system and causing damage to the project; the water collection structure mainly relies on increasing the thickness of the soil layer to achieve heat preservation. This method is slow in construction, poor in effect and unfavorable for environmental protection...
