Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing.

[0042] figure 1 A connection device 100 according to the invention is shown. Such as figure 1 As shown, in the direction from the first end to the second end, the connection device 100 includes a connection device 1 , a conduction device 3 and an injection device 5 which are sequentially connected and conducted. Wherein, the connecting device 1 is used for communicating with the grouting pipe for channel grouting, so as to receive the grouting liquid in the grouting pipe. The conduction device 3 is detachably arranged downstream of the connection device 1 to receive the grouting fluid from the connection device 1 . The injection device 5 is detachably arranged downstream of the conduction device 3, and is used for delivering the grout received from the conduction device 3 to the bridge tunnel. And the inner cavity of the conduction device 3 is configured to conduct in t...

Abstract

The invention provides a connecting device for duct grouting of bridge prestress. The connecting device comprises a connecting device body for being connected with a grouting pipe of duct grouting ina communicated mode, a conduction device capable of being communicated and detachably connected with the connecting device body, and an injection device capable of being communicated and detachably connected with the conduction device, wherein an inner cavity of the conduction device is conducted in a first state and interrupted in a second state. By means of the connecting device, grouting operation becomes quite convenient, grouting fluid can be well controlled, the grouting fluid utilization efficiency is improved, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a connection device for channel grouting of bridge prestress. Background technique [0002] With the rapid development of my country's economy, the transportation industry is playing an increasingly important role in economic development, but my country is still facing problems such as incomplete road coverage, insufficient transportation capacity, and unformed road network planning. In the next ten years, with the development of road network planning, especially in mountainous areas, river areas and the development of urban viaducts, bridges will be used more and more. [0003] In the prior art, there is no special connecting device for connecting the grouting pipe and the bridge channel, so that the grouting operation is inconvenient, and at the same time, the waste of grouting fluid is serious. Contents of the invention [0004] Aiming at part or all of the abov...
