Abstract
The invention relates to a sand blower. The sand blower is characterized by being composed of an air inlet pipe, a sand storage pipe and a sand outlet pipe which are successively connected through flanges, wherein the upper part of the sand storage pipe is vertically and fixedly connected with a sand inlet hopper communicated therewith, and the lower part of the sand storage pipe is fixedly connected with a ground jack. The invention has the following beneficial effects: sand filling is carried out to ensure that a heating pipe is kept a certain distance away from a push pipe, plays the function of protecting the shuck of the heating pipe while the heating pipe expands with heat and contracts with cold, and achieves the purpose of fixing the heating pipe; the sand filling process saves time and labor, improves working efficiency, and shortens the whole engineering period; and simultaneously, fixed pipe diameter is designed without considering the standing space for manual sand filling, thereby reducing the design size of the fixed pipe diameter, lowering the material cost and reducing the push resistance of the push pipe.
Description
Technical field
The invention belongs to jetting tool, relate in particular to a kind of sandblast that is applied to adopt trenchless technology to lay push pipe and heating pipeline filling fixture in the heat pipeline.
Background technique
Heat supply network by defeated hot main line, join hot main line, branch line etc. and form.Defeated hot main line is drawn from thermal source, does not generally connect branch line; Join hot main line from failing hot main line or directly picking out, by joining a heat alignment user heat supply from thermal source.
The heat supply network layout is mainly determined according to city heat load distribution situation, block present situation, development plan and geology terrian condition etc., generally is arranged to dendritic.When by multi-source heating, for standby mutually, improve the reliability and the flexibility of heat supply, can establish connecting tube between the defeated hot main line of each thermal source, also can be arranged to ring-type.How along the street urban district pipeline road one side and other underground utility is arranged in parallel.The layout of heat supply network should make pipeline walk at the heat load center as far as possible, and heat range of heat is the shortest, and minimum to the city interference, construction and operation management are convenient.
Heat supply pipeline has underground laying and over ground installation dual mode.Underground laying does not influence the urban transportation and the appearance of the city, is the system of laying that city heat supply is extensively adopted.Over ground installation also claims built on stilts laying, and its low cost is easy to maintenance, is used for the special areas of geological structure such as industrial region, suburb, level of ground water height, permafrost area, settlement by soaking soil district more, and crosses over locations such as railway, highway, river.Majority is established special stand.According to the support height difference, be divided into high trestle, medium-height trestle, low trestle and ground and lay.Current, pay much attention to for exploitation river view economy in the city, so hot pipe network does not adopt the over ground installation method of crossing over the location, river, the method that adopts trenchless technology laying heat pipeline to pass through the river bed.This kind method is that the heat supply pipeline of 6 meters fixed length is pushed in the push pipe by joint, and every joint heating tube is by fixedly connected the pushing between the push pipe of clip head and the tail, and then between push pipe and heating tube the infilling work fine sand.Adopt artificial the filling for a long time always.Given diameter need be considered the erect-position space of artificial back-up sand, thus cause the design size of given diameter to strengthen, waste material and strengthened the implementation resistance of push pipe.Artificial back-up sand labor intensity is big, effect is low, directly influences project process.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of sandblast that is applied to adopt trenchless technology to lay push pipe and heating pipeline filling fixture in the heat pipeline is provided, time saving and energy saving, working efficiency is provided.
The present invention for achieving the above object, by the following technical solutions: a kind of sandblast, it is characterized in that: mainly by the suction tude, the storage sand tube that connect by flange successively with go out sandpipe and constitute, described storage sand tube upper vertical is affixed be communicated with it advance the sand hopper, the storage sand tube bottom is connected with supporting leg.
Described storage sand tube is made of straight-run of pipe and one section reducer pipe, described reducer pipe by flange with go out sandpipe and be connected.
Beneficial effect: can guarantee to keep certain distance between heating tube and the push pipe by back-up sand, not only when heating tube expands with heat and contract with cold, play the effect of protection heating tube crust, can also reach the fixedly purpose of heating tube.Sand filling process is time saving and energy saving, increases work efficiency, and shortens the integrated engineering duration.Simultaneously, the design given diameter does not need to consider the erect-position space of artificial back-up sand again, can reduce the design size of given diameter, reduces the implementation resistance that cost of material has also reduced push pipe.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of sandblast, mainly by the suction tude 1, the storage sand tube 2 that connect by flange 6 successively with go out sandpipe 3 and constitute, described storage sand tube upper vertical is affixed be communicated with it advance sand hopper 4, the storage sand tube bottom is connected with supporting leg 5.Described storage sand tube is welded by straight-run of pipe 2-1 and one section reducer pipe 2-2, described reducer pipe by flange with go out sandpipe and be connected.
During use, at first with a push pipe front end shutoff part, suction tude is communicated with air pump by sebific duct, manually in hopper, add sand, go out sandpipe and be connected with sebific duct, sebific duct is put between push pipe and the heating tube, open air pump and begin inside sandblast, along with sand 7 fills up, blast limit, limit retreats sebific duct, until all completing.
Adopt 25M
3Air pump, suction tude diameter phi 55, storage sand tube straight tube diameter phi 160, by the caliber φ 88 behind the reducing, hopper 550 * 550 needs three people shovel sand continuously in hopper, could satisfy the speed of sandblast, efficient is very high.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. sandblast is characterized in that: mainly by the suction tude, the storage sand tube that connect by flange successively with go out sandpipe and constitute, described storage sand tube upper vertical is affixed be communicated with it advance the sand hopper, the storage sand tube bottom is connected with supporting leg.
2. sandblast according to claim 1 is characterized in that: described storage sand tube is made of straight-run of pipe and one section reducer pipe, described reducer pipe by flange with go out sandpipe and be connected.
