Description

Pipeline water-tight device through walls and assemble the heat-insulated pipe of this water-tight device
Technical field
The utility model belongs to prefabricated thermal isolated pipe pipeline technical field through walls, particularly a kind of pipeline water-tight device through walls and assemble the heat-insulated pipe of this water-tight device.
Background technique
In prefabricated thermal isolated pipe pipeline construction process; conventionally can run into pipeline situation through walls; in the time that level of ground water is higher; underground water is easily provided with in the inspection shaft of the equipment such as compensator, valve by infiltration inspection shaft in position through walls etc.; cause device damage in inspection shaft, therefore the waterproof of pipeline position through walls is most important.
Conventionally in order to reach waterproof requirement, can be at wall feed-through pipeline outer installment rigid waterproofing device, the common way of this rigid waterproofing device is between pipeline and body of wall, water string to be set and water stop ring carries out water-proofing treating.Although adopt above-mentioned way can arrive to a certain extent the object of waterproof, but because water-proofing material is generally thinner, cannot arrive enough waterproof thickness and intensity, so waterproofing effect is limited, particularly in level of ground water in the engineering higher than buried depth, the working life of this water-tight device through walls is shorter, easily leaks, and still easily can cause the interior key equipment of inspection shaft impaired.
In order to address the above problem, the applicant had proposed a solution last year, be in Chinese patent literature (CN202660072U), to disclose adjustable sealing to through the wall oversleeve for a kind of prefabricated direct-buried heat-insulated pipe, comprise steel part main body, it comprises Yi Ge center steel pipe and two steel loops, described two steel loops are separately fixed at the two ends of described steel pipe, and on one of them steel loop, are provided with several pin-and-holes; O-ring seal, it is arranged on described steel part body interior; Movable back-up ring, it is nested with on described heat-insulated pipe and is arranged on described steel part body interior; Bolt is refuted sheet, has screw on it, and described bolt is refuted sheet and is inserted into described pin-and-hole inside, in described screw, is bolted with bolt.Said apparatus is compared and traditional approach, although waterproofing effect strengthens, and still has following defect: 1, its movable back-up ring passes through bolton and then press seal cushion rubber, thereby plays seal action, but only rely on O-ring seal to seal, waterproofing effect has much room for improvement; 2, affected by self weight of pipeline and load-bearing, pipeline easily sinks, and can not keep concentric with sleeve through walls, and the rear O-ring seal of pipeline sinking is positioned at the part of pipeline top and easily becomes flexible, and will affect like this waterproofing effect at pipeline place through walls, easily produces seepage; 3, wherein, be generally carbon steel material for the bolt of fastening press seal cushion rubber, get rusty easily, once getting rusty, bolt just cannot regulate as required again the sealing of O-ring seal, so must often change, this will affect the maintenance of wall feed-through pipeline, also can increase maintenance cost; 4, can, around moving along pipeline tangent direction, easily cause bolt looseness, and then affect waterproofing effect for the sheet of refuting of fixing bolt.
In sum, existing pipeline water-tight device waterproofing effect through walls is poor, is difficult to meet delivery receiving acceptance and usage requirement.
