Abstract
The invention discloses a method for preventing a corrugated pipe from being damaged in a filled layer. The method includes the following steps that (1) a groove for burying the corrugated pipe is excavated; (2) a polyvinyl chloride (PVC) pipe longer than the corrugated pipe is selected and inserted into the corrugated pipe, one end of the PVC pipe is connected with a bolt U-shaped pipe, the other end of the PVC pipe is sealed by tightening a bolt stopper, and a water filling level mark is engraved to the end, far from the PVC pipe, of the bolt U-shaped pipe; (3) water is injected into the PVC pipe through one end of the bolt U-shaped pipe till the water level reaches the water filling level mark; and (4) after a filler is compacted and meets the requirement, the bolt stopper is unscrewed, water in the PVC pipe is completely discharged, the PVC pipe is removed, and the construction of next corrugated pipe is performed. The PVC pipe is adopted as a protective pipe for construction of the corrugated pipe; water is injected, and the filler is compacted through water pressure; therefore, the damage to the corrugated pipe is greatly reduced, and manpower and mechanical consumption is reduced; the construction quality of the corrugated pipe is improved, the work efficiency is guaranteed, and the construction period is further shortened.
Description
Technical field
The invention belongs to bellows construction field, particularly relate to a kind of method preventing bellows destroyed in packing course.
Background technique
Along with China is to the attention of Infrastructure and construction, our Infrastructure have also been obtained significant progress, along with the attention to safety, also more and more higher to the requirement of construction material.Bellows is a kind of construction material be widely used in Infrastructure industry, bellows is a kind of tubing of wave sample of profile rule, be mainly used in needing very little bending radius, irregular turning, pipeline will produce flexible part or be not easy to do connecting of pipeline and pipeline, flexible, a small amount of elongation of bellows or compression by the occasion that fixing elbow is installed.Existing bellows is that plastics are made, is easy to after mounting be destroyed.
Summary of the invention
The object of the present invention is to provide a kind of method preventing bellows destroyed in packing course, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, present invention employs following technological scheme:
Prevent the method that bellows is destroyed in packing course, comprise the following steps:
1) groove of excavation for burying bellows underground;
2) choose the pvc pipe that a length is longer than bellows, inserted by pvc pipe in bellows, pvc pipe one end is connected with bolt U-tube, and its other end is by the bolt plug sealing of tightening, and bolt U-tube is carved with water filling position away from pvc pipe one end;
3) by bolt U-tube one end to water filling in pvc pipe till water level reaches water filling position;
4) reach after requirement until filling compaction, open the bolt plug tightened, the water of giving out light in pvc pipe, takes pvc pipe away, carries out next bellows construction.
Preferably, the width of groove bottom land 60cm larger than corrugated pipe pipeline diameter to be buried underground in step 1).
Preferably, step 2) middle bellows diameter 8-12cm larger than pvc pipe diameter.
Preferably, step 2) in the pvc pipe two ends length of stretching out corrugated tube end be respectively 25-35cm.
Compared with prior art, beneficial effect of the present invention is as follows:
The present invention adopts pvc pipe to construct protective tube as bellows; by injecting water; utilize hydraulic pressure by filling compaction; greatly reduce the damage of bellows; reduce artificial, machinery consumption, effectively reduce construction cost, improve the construction quality of bellows; working efficiency have also been obtained guarantee, accelerates the duration further.
Accompanying drawing explanation
Fig. 1 is the integral installation structural representation of this method.
Embodiment
Below in conjunction with embodiment, optimal way of the present invention is described in further detail.
Refer to shown in Fig. 1, a kind of method preventing bellows destroyed in packing course, comprises the following steps:
1) groove of excavation for burying bellows 1 underground, the width 60cm larger than bellows 1 pipe diameter to be buried underground of groove bottom land.
2) pvc pipe 2 that a length is longer than bellows 1 is chosen, and bellows 1 diameter 8-12cm larger than pvc pipe 2 diameter, pvc pipe 2 is inserted in bellows 1, and bellows 1 end 25-35cm is stretched out at pvc pipe 2 two ends respectively, pvc pipe 2 one end is connected with bolt U-tube 3, and its other end is sealed by the bolt plug 4 tightened, bolt U-tube 3 is carved with water filling position 4 away from pvc pipe 2 one end.
3) by bolt U-tube 3 one end to water filling in pvc pipe 2 till water level reaches water filling position 31.
4) reach after requirement until filling compaction, open the bolt plug 4 tightened, the water of giving out light in pvc pipe 2, take pvc pipe 2 away, carry out next bellows 1 and construct.
The present invention proposes a kind of method preventing bellows destroyed in packing course; the pvc pipe 2 less than bellows 1 diameter is inserted in bellows 1; pass through toward water filling in pvc pipe 2 again; pvc pipe 2 is utilized to increase the compressive resistance of bellows 1; prevent bellows 1 from being damaged by pressure because pressure is excessive; to construct protective tube as bellows 1 by adopting pvc pipe 2; greatly reduce the damage of bellows 1; reduce artificial, machinery consumption; effective reduction construction cost; improve the construction quality of bellows 1, working efficiency have also been obtained guarantee, accelerates the duration further.Method of construction of the present invention is easy and simple to handle, effectively reduces construction cost, greatly improves efficiency of construction.
Above embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technological scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
