Abstract
The utility model relates to an air exhaust device of a prestressed pipeline, which is used for bridges, etc. The utility model is composed of a connecting joint seat, an air exhaust pipe, and an outlet valve. When the utility model is arranged at a reserved venting hole position of the prestressed pipeline, the function of mud jacking and air exhaust can be safely achieved. The utility model has the advantages of standardization of accessories, convenient operation, and wide adoption range.
Description
The utility model belongs to bridge construction engineering field, and it relates to the mud jacking venting gas appliance of pre-buried prestress pipe in a kind of concrete-bridge.
The mud jacking venting gas appliance of used prestress pipe in the present domestic civil engineering, adopt drawn the outer mode of member after directly being inserted and secured on the prestress pipe after minor diameter hose or plastic tube blocked more, there are some defectives in this mode, cause difficulty when cable wire being passed, even can't pass as the end in the sebific duct insertion prestress pipe.Sebific duct or plastic tube such as insufficient strength are prone to distortion and cause stifled slurry in addition.The soundness that sebific duct is connected with prestress pipe in construction also is difficult for guaranteeing.
It is a kind of easy to use that the purpose of this utility model is to provide, the venting gas appliance of good connecting effect.
The purpose of this utility model is achieved in that giving vent to anger of joint chair 1 chews the outlet pipe 3 that has screw thread to spin on 2, the exhaust outlet valve 4 that has screw thread to spin at the other end of outlet pipe.
The utility model is owing to adopt the special plastic extrusion that meets requirement of strength, all adopting closely between its joint chair, valve and the outlet pipe, threaded engagement is connected, and joint chair 1 has better flexibility, can closely be connected with the prestress pipe of different-diameter, and can be provided with fixing arbitrarily according to the spatial position of prestress pipe.Accessory is in light weight, and easy construction is applied widely.
Accompanying drawing 1 is the venting gas appliance structural representation.
Accompanying drawing 2 is venting gas appliance scheme of installations.
Accompanying drawing 3 is venting gas appliance structural representations of cylindrical shape joint chair.
Describe below in conjunction with accompanying drawing.(see figure 2): when prestress pipe 5 during at concreting beam body 6 not, at need the venting gas appliance place is set and is reserved with exhaust port, giving vent to anger of the joint chair 1 of venting gas appliance shown in Figure 1 chewed 2 joint chair is snapped onto on the prestress pipe after aiming at exhaust ports, joint chair 1 and pipeline 5 are completely fixed with tape paper.Outlet pipe is drawn outside template or the beam body 6, after waiting to have built the beam body concrete and reaching designing requirement intensity, pipeline is carried out mud jacking, the air in the mud jacking process in the pipeline is by the venting gas appliance exhaust, up to mortar throttle down when valve 4 flows out, finish mud jacking exhaust construction.
For the needs that are fit to connect between the prestress pipe, this reality made the novel venting gas appliance (see figure 3) that proposes a kind of cylindrical shape joint chair again, during use two sections prestress pipes is inserted in joint chair and fixes to get final product.
Claims (2)
1, a kind of mud jacking venting gas appliance that is used for prestress pipe is characterized in that: chew the outlet pipe that has screw thread to spin giving vent to anger of joint chair, the exhaust outlet valve that the other end of outlet pipe has screw thread to spin.
2, venting gas appliance according to claim 1 is characterized in that: joint chair is a cylindrical shape.
