Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses section of jurisdiction freeze-proof device is used in section of jurisdiction production. Referring to fig. 1 and 2, the deformable member 1 is included, the deformable member 1 takes a long shape, and the deformable member 1 is deformable to be contracted radially. When the arc-shaped opening of segment 2 is placed upwards, one end of deformable element 1 is inserted into bolt hole 21 of segment 2 or inserted downwards from the upper end of lifting hole 22 of segment 2, so that deformable element 1 is placed into bolt hole 21 or lifting hole 22 of segment 2. When the segment 2 is placed in the open air and accumulated water is generated in the hole of the segment 2, the deformable part 1 can provide enough accumulated water and ice expansion space through radial contraction in the process of icing of the accumulated water.
Referring to fig. 2 and 3, the deformable member 1 is a flexible tube 3, and other embodiments may use flexible rubber strips. Both ends of flexible pipe 3 are sealed, and the inside of flexible pipe 3 is hollow structure, can adopt sticky or jam when sealing flexible pipe 3's both ends, and flexible pipe 3 in this implementation is made for thermoplastic material, can select for PVC hose or PE hose or PP hose. When both ends of flexible tube 3 are sealed, both ends of flexible tube 3 are heated to be melted, and then both ends of flexible tube 3 are closed by extrusion. When soft pipe 3 used, the inside of soft pipe 3 was the air to when receiving the extrusion, the air can compress, and then for the downthehole ponding icing process of section of jurisdiction 2 provides sufficient expansion space, ensures that section of jurisdiction 2 can not break.
Referring to fig. 2, in order to make the flexible tube 3 sink into the inside of the water accumulated in the hole of the segment 2, a weight 4 is provided in the middle of the flexible tube 3, and when the flexible tube 3 is put into the hole of the segment 2, the buoyancy of the flexible tube 3 is overcome by the gravity of the weight 4, thereby making the flexible tube 3 sink into the inside of the water accumulated in the hole of the segment 2. When the downthehole ponding that takes place of section of jurisdiction 2 freezes, the hole upper portion that is close to section of jurisdiction 2 usually takes place earlier to freeze to the in-process that the hole ponding of section of jurisdiction 2 freezes at end again is close to the minimum position of flexible pipe 3 gradually, and then can make flexible pipe 3 furthest keep changing at the frozen overall process of ponding, thereby more be favorable to preventing breaking of section of jurisdiction 2.
Referring to fig. 2, the weight 4 is sand, the soft tube 3 is filled with sand, the amount of the sand is small, and after the soft tube 3 is filled with the sand, the end of the soft tube 3 is plugged. The amount of sand is enough to overcome the buoyancy of the flexible tube 3, and the volume of the sand accounts for 0.1-0.3 of the volume of the flexible tube 3. Thereby can avoid the sand to be full of when soft pipe 3, the deflection of soft pipe 3 is less, and when having sufficient deformable space in soft pipe 3 simultaneously, the tip of avoiding soft pipe 3 is propped open by inside gas pressure to lead to the sealed of 3 tip of soft pipe to lose efficacy, and then the deformation when unable ponding freezes behind the soft pipe 3 inside entering rainwater. In addition, the sand is arranged behind the inner part of the soft pipe 3, the sand is relatively loose, the soft pipe 3 can be immersed into the accumulated water in the hole of the pipe piece 2, and meanwhile, when the soft pipe 3 is extruded, the sand can also move, so that relative extrusion force can not be formed when the accumulated water in the hole of the pipe piece 2 is iced. The sand is freely movable inside the flexible tube 3. When placing in the bolt hole 21 of section of jurisdiction 2 when soft pipe 3, because the gravity of sand makes sand automatically move to the lowest position of soft pipe 3, soft pipe 3 sets up along bolt hole 21's trend, and then can make the sand be in the lowest position of the bolt hole 21 of section of jurisdiction 2, and then makes soft pipe 3 sink to the deepest of ponding in the bolt hole 21 of section of jurisdiction 2 under the effect of sand.
Referring to fig. 2 and 3, the flexible tube 3 is provided with an arc shape, and the end of the flexible tube 3 protrudes from the end of the hole of the segment 2, so that the flexible tube 3 can be easily inserted from the end of the bolt hole 21 of the segment 2. Meanwhile, the end part of the flexible pipe 3 is exposed out of the hole of the duct piece 2, so that the flexible pipe 3 can be conveniently taken out of the hole of the duct piece 2 when the duct piece 2 is used.
The embodiment also discloses a segment freeze-proof device's application method for segment production, the curved opening that segment 2 is places up, it is downthehole to take out flexible pipe 3 and insert segment 2, the hole of segment 2 includes bolt hole 21 and hoist and mount put the hole, need add heavy object 4 in flexible pipe 3 before flexible pipe 3 inserts, heavy object 4 selects the sand, the sand is poured into in flexible pipe 3, then carry out the shutoff with flexible pipe 3's both ends, the shutoff adopts the heating to make flexible pipe 3's both ends melt the back extrusion bonding. When the downthehole ponding of section of jurisdiction 2 takes place to freeze, soft pipe 3 changes, and the sand receives the extrusion also can remove simultaneously, and then makes soft pipe 3 take place radial deformation, makes the downthehole ponding of section of jurisdiction 2 freeze and carries out extrusion deformation to soft pipe 3, and the radial deformation through soft pipe 3 provides sufficient space for the frozen inflation of ponding in section of jurisdiction 2, avoids section of jurisdiction 2 to take place to break.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
