Abstract
The utility model provides a grout pipeline with steam bag which the outer fixed surface that the main points lay in at the pipeline has the zone of heating, and zone of heating outside parcel has the heat preservation, and between pipeline and heat preservation, the interval is fixed with ring carrier. The utility model has the advantage of simple structure, it is thermal -insulated to utilize the gasbag to keep warm, can reduce calorific loss, because the grout process is that the operating mode position is also changing at any time in continuous change, and application hose aeration, it is can application scope wide, convenient operation, as long as the collection is convenient, increases the small investment, the environmental protection with air bag deflation the time spent.
Description
Technical field
The utility model relates to hydraulic engineering Foundation Anti-seepage grouting treatment, house construction engineering ground and the field such as pattern foundation pit supporting structure process, highway construction treatment of soft foundation.In particular to the grout lines with hot gas capsule used in the low temperature environment of pole, severe cold area.
Background technology
At present, grouting technique has achieved the development of advancing by leaps and bounds, due to grouting agent mainly cement and water, and water will be protected and really just can must carry out in environment above zero under normal liquid state, and cement and water mixing Post RDBMS also could normally must carry out at temperature condition above freezing.At extremely frigid zones, cannot carry out grouting construction operation in the pole low temperature environment of severe cold season, this is mainly under low temperature environment, and grouting agent and water are all very easily icing, indices after mixed grouting is grout curing is not up to standard or substantially cannot solidify, and causes quality to ensure.Finally cannot sequential production, so that the construction period extended, increase cost of investment.
Summary of the invention
Main purpose of the present utility model overcomes the problem cannot constructed in the winter time in the grouting of the extremely low severe cold area object of construction production of temperature environment, provides a kind of grout lines with hot gas capsule, can not work continuously by low temperature effect to make grouting.
The technical scheme that utility model adopts is a kind of grout lines with hot gas capsule, and its main points are to be fixed with zone of heating at the external surface of pipeline, are enclosed with insulation layer outside zone of heating.
Utility model utilizes zone of heating to carry out the temperature heating to ensure cement or water in pipeline, utilizes air bag to carry out thermal insulation.
Zone of heating is formed by insulation electrothermal rope or ribbon heater curl winding pipeline.Insulation layer is air bag.
Ring support is fixed with at the external surface interval of pipeline.
Ring support spacing is 0.5m ~ 1.0m.
Due in filling process, grout lines has vibration, for preventing producing friction between thin walled hose, damaging flexible pipe, destroying airbag structure, lose function.
The utility model has the advantage of that structure is simple, utilize air bag to carry out thermal insulation, can thermal loss be reduced, because filling process is in continuous change, Working pasition is also changing at any time, use flexible pipe aeration, can be applied widely, easy to operate, as long as the used time is not by air bag deflation, collection is convenient, increases small investment, environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 pipeline 11 ring support 2 zone of heating 3 insulation layer.
Detailed description of the invention
Below in conjunction with view, the utility model is described in detail.
As shown in Figure 1, a kind of grout lines with hot gas capsule, is fixed with zone of heating 2 at the external surface of pipeline 1, is enclosed with insulation layer 3 outside zone of heating 2.Selection for pipeline good heat preservation performance, high pressure resistant, wear-resisting rubber tube or steel pipe etc., compact siro spinning technology is answered between union, guarantee that union is without leaking with pipeline without breakage, with insulation electrothermal rope or ribbon heater curl winding pipeline outer wall, as zone of heating, examination energising is carried out to the electrothermal rope connected or ribbon heater, check with or without electric leakage or short circuit phenomenon, and it is solid with insulating tape colligation Lao, electrothermal rope or ribbon heater is made to be close to tube wall, insulation layer 3 is air bag, be set with one deck diameter slim flexible plastic tube larger than interior pipe outward fixing the pipeline outside zone of heating, rubber tube, plastic pipe, two is carried out closed closely knit, diameter after inflation is that 3 ~ 5 times of diameter of inner pipe are advisable, and installs gas tube and valve additional, carries out encapsulation process, guarantee without gas leak phenomenon.Inflated by the soft thin-walled outer tube closed, air pressure controls at about 0.1 ~ 0.2Mpa, makes it form an air bag.In 30min, carry out inflating, being energized before pipeline uses, allow electrothermal rope or ribbon heater electrified regulation, make temperature in its air bag be increased to 15 DEG C ~ about 30 DEG C; Ensure that cement grout is not congealed.Owing to carrying out cementing operations in extremely cold season, pipeline is unsuitable long, should be more suitable in 50m.Due in filling process, grout lines has generation vibration, rubs for preventing from producing between interior pipe and thin walled hose, damages flexible pipe, destroys airbag structure, loses function.Maked somebody a mere figurehead by pipeline 1 ring support 11, spacing installs a support by every 0.5m ~ 1.0m, and ring support is between pipeline and insulation layer.Guarantee between inner and outer pipes, there is certain space, do not contact with each other, produce friction.
Claims (2)
1. the grout lines with hot gas capsule, it is characterized in that being fixed with zone of heating (2) at the external surface of pipeline (1), zone of heating (2) outside is enclosed with insulation layer (3), described zone of heating (2) is formed by insulation electrothermal rope or ribbon heater curl winding pipeline, insulation layer (3) is air bag, be fixed with ring support (11) at the external surface interval of pipeline (1), ring support is between pipeline and insulation layer.
2. a kind of grout lines with hot gas capsule according to claim 1, is characterized in that, ring support (11) spacing is 0.5m ~ 1.0m.
