Description
Technical field
The present invention relates to Lining Technique fields, and in particular to a kind of concrete pumping lever arm and the coagulation containing this lever arm
Native material distributing machine.
Background technology
When tunnel double-lining concrete construction, need concrete pumping to template and excavation face through different location in template
Between cavity in complete to pour.It is desirable to need to be by manually by clip, the pump on pump line when replacing concrete pumping interface
Pipe is removed, and is replaced the pump line for being suitble to length and is installed after being docked again with next pumping interface behind the outlet of adjustment conduit positions.
Such mode has the following defects：(1) it needs frequently to replace pumping interface in constructing, more alias is both needed to every time
It tears pipe open, changes pipe, cleans, taking over and fixing, workload and labor intensity are big, and time-consuming；(2) disconnect pipe needs to stop in the process
Pump concrete, because the slump loss that dead time length is trapped in pump line easily causes plugging；(3) for a long time
Pump concrete, newly-laid concrete and the concrete poured before are easy to form cold seam again after pause, influence pouring quality；
(4) pumping interface is frequently replaced, can remain and overflow part concrete in pipe, cause the pollution of waste and scene；(5) pump is replaced
It send and needs to be operated in trolley middle and upper part when interface, the higher easy initiation safety accident in position.
In conclusion being badly in need of a kind of structure simplifies, is easy to use, construction efficiency is high grouting equipment to solve the prior art
The problem of.
