Description

A kind of insulated piping anchor block and its construction method of installation
Technical field
The present invention relates to a kind of insulated piping anchor block and its construction methods of installation, belong to pipeline engineering technical field.
Background technology
Buried heated transportation pipeline generally sets insulating layer in pipeline external surface, prevents pipeline heat by Frozen Ground Area Loss destroys the thermal balance of surrounding frozen soil layer.It is restrained line because of the position for generation of expanding with heat and contract with cold in part hot-bending bends position It moves, it is necessary to set anchor block (also referred to as anchoring pier).Pipeline and anchoring flange in anchor block directly connect without insulating layer with concrete It touches, and anchor block surface is also not provided with insulating layer, and pipe-line system heat is caused largely to scatter and disappear at anchor block.Frozen soil is to temperature pole For sensitivity, pipe-line system heat largely scatters and disappears at anchor block, will destroy the thermal balance on surrounding frozen soil stratum, thaw collapse etc. is caused to ask Topic influences pipe safety, therefore anchor block becomes the weak link of pipeline heat-insulating system.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of insulated piping anchor block and its installation sides Method, suitable for the pipeline anchor of Frozen Ground Area, by setting heat insulation layer in anchor block outer surface, block pipeline system thermal to Scattering and disappearing in frozen soil stratum, so as to fulfill pipe-line system energy consumption, protection of permafrost layer thermal balance is reduced.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of insulated piping anchor block, the anchor block outer surface set heat insulation layer, and the heat insulation layer outer surface is equipped with and smears Face rubber cement;Wherein, the heat insulation layer is fixed on by bonding agent or expandable nail on the anchor block outer surface, the heat insulation layer Material is rigid polyurethane foam or extrusion molding polystyrene polyfoam.
Further, the thickness of the heat insulation layer is not less than 50mm.
Further, the rigid polyurethane foam or the apparent density of extrusion molding polystyrene polyfoam are not less than 30kg/m3
Further, the rigid polyurethane foam or the compression strength of extrusion molding polystyrene polyfoam are not less than 100kPa。
Further, the heat insulation layer outer surface is equipped with two layers of finishing mucilage, is pasted among two layers of finishing mucilage Grid cloth.
Further, the grid cloth is fiberglass gridding cloth.
The construction method of installation of the insulated piping anchor block, comprises the following steps:
Step 1, in bottom of foundation ditch casting concrete bed course, tile one layer of heat insulation layer on the concrete cushion;
Step 2, formwork and casting concrete anchor block on the heat insulation layer, the anchor block conserve 2- in step 1 After 14 days, the template of the anchor block is removed;
Step 3, one layer of thermal insulation is fixed by bonding agent or expandable nail respectively in the top surface of the anchor block and four sides Layer;
Step 4, heat insulation layer outer surface in step 3 applies one layer of finishing mucilage, then paving fiberglass gridding cloth, After the finishing mucilage solidifies and dries, then one layer of finishing mucilage of even application, and conserve 2-14 days;
Step 5, foundation pit earth back-filling in layers and tamp, complete the installation of insulated piping anchor block.
Further, the rigid polyurethane foam is in-situ spraying or is prefabricated rear mounted on the anchor block Outer surface.
Further, the extrusion molding polystyrene polyfoam is the prefabricated rear outer surface for being mounted on the anchor block.
Beneficial effects of the present invention are:
Insulated piping anchor block of the present invention, suitable for the pipeline anchor of Frozen Ground Area, by anchor block appearance Face sets heat insulation layer, blocks pipeline system thermal scattering and disappearing into frozen soil stratum, so as to fulfill pipe-line system energy consumption, protection is reduced Frozen soil layer thermal balance.
