Abstract
The utility model belongs to construction engineering technical field, specifically prefabricated direct-buried thermal insulation pipe road water string, including pipeline, insulating layer and outer tube, the outer tube is externally provided with water string, gap between the both sides and outer tube of water string is filled and is sealed with asbestos cement, is filled with spunyarn between asbestos cement.Directly buried pipeline insulating layer can be made continuous, pipeline thermal loss can be prevented, also prevent due to insulating layer and outer tube disconnect and causing insulating layer to make moist influences heat-insulating property.
Description
Technical field
The utility model belongs to construction engineering technical field, and the waterproof of outer wall of basement is worn for prefabricated direct-buried thermal insulation pipe road
Casing, heating system is generally in underground heat exchange station exterior wall, underground consumer heat inlet exterior wall etc..
Background technology
In the prior art (standard collective drawings), it is through walls that water string way at outer wall of basement is worn in prefabricated direct-buried thermal insulation pipe road
Place's removal insulating layer and outer tube.It will appear brokenly because pipeline expands with heat and contract with cold at the secondary seal of prefabricated direct-buried thermal insulation pipe road outer tube
Damage, infiltration influence heat insulation effect, corrosive pipeline.
Utility model content
To be solved in the utility model is to overcome the deficiencies of existing technologies, provide a kind of safety and reliability for prefabricated
Directly-buried thermal insulation pipes wear water string at outer wall of basement.
Technical solutions of the utility model are：Prefabricated direct-buried thermal insulation pipe road water string, including pipeline, insulating layer and housing
Pipe, the outer tube are externally provided with water string, and the gap between the both sides and outer tube of water string is filled out with asbestos cement
It fills and seals, be filled with spunyarn between asbestos cement.
The water string is equipped with wing ring.
The water string is process using stainless steel.
Insulating layer and outer tube are equipped with outside the pipeline successively.
The advantages of the utility model
When prefabricated direct-buried thermal insulation pipe road passes through water string, pass through together with insulating layer and outer tube, outer tube with
It is filled with filler between water string.Directly buried pipeline insulating layer can be made continuous, pipeline thermal loss can be prevented, also prevented
Due to insulating layer and outer tube disconnection, causing insulating layer to make moist influences heat-insulating property.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model prefabricated direct-buried thermal insulation pipe road water string；
Wherein 1 pipeline, 2 insulating layers, 3. outer tubes, 4 steel water strings, 5 wing rings, 6 asbestos cements, 7 spunyarns, 8 coagulations
Native exterior wall.
Specific implementation mode
1 explanation prefabricated direct-buried thermal insulation pipe road provided by the utility model water string below in conjunction with the accompanying drawings；Including pipeline 1,
Insulating layer 2 and outer tube 3 are equipped with outside pipeline 1 successively, outer tube 3 is high density polyethylene (HDPE) outer tube；
Outer tube 3 is externally provided with water string 4, and water string 4 is steel, between the both sides and outer tube of water string 4
Gap asbestos cement 6 is filled between asbestos cement 6 with spunyarn 7, and closely consolidated；By the welding of wing ring 5, (periphery is full
Weldering) on water string 4, it is carried out when concrete of basement exterior wall 8 is constructed pre-buried；Following table gives common in actual use
Caliber and each component size.
Each caliber water string size refers to following table：
