This utility model be the technical scheme is that a kind of glass reinforced plastic pipe water test unit, including fixing seat, fixes
Support, drive end bearing bracket and rear end cap, described fixed support is arranged on described fixing seat, described drive end bearing bracket and described fixed support
Hinged, it is provided with pressure testing inner tube between described drive end bearing bracket and described rear end cap, installs between described drive end bearing bracket and described rear end cap
The pressure testing glass reinforced plastic pipe coaxial with described pressure testing inner tube, is formed circular between described pressure testing inner tube and described pressure testing glass reinforced plastic pipe
Pressure testing hydrospace, described pressure testing inner tube is provided with vent valve, described fixing seat is provided with support described pressure testing fiberglass
The cushion block of pipe.
As preferably, one end of described pressure testing inner tube is fixing with described drive end bearing bracket to be connected, and its other end passes through nut bolt
Structure is detachably fixed with described rear end cap and is connected.
As preferably, described vent valve is arranged on the described pressure testing inner tube position, top side, one end near described drive end bearing bracket.
As preferably, described drive end bearing bracket and described rear end cap are all coated on described pressure testing glass reinforced plastic pipe outer wall, described pressure testing
Glass reinforced plastic pipe outer wall is provided with on sealing ring, described drive end bearing bracket and described rear end cap to be provided with and embeds cooperation for above-mentioned sealing ring
Seal groove.
The beneficial effects of the utility model are: owing to this utility model uses said structure, in pressure testing glass reinforced plastic pipe
Portion arranges pressure testing inner tube so that pressure testing hydrospace is formed circular, reduces the pressure testing water yield so that drive end bearing bracket and the water of rear end cap
Pressure thrust less (generally can arrive about the 1/10 of tunneling boring thrust, the least), it is easy to accomplish seal, it is to avoid occur oozing
Leakage；Drive end bearing bracket is hinged with fixed support simultaneously, and rear end cap side is the most unsettled so that this assay device is more flexible, installs more square
Just, by rotating pressure testing glass reinforced plastic pipe, the position of vent valve can be made higher than other pressure testing inner tube position, be more convenient for pressure testing water
Air emptying in space；And sealing ring is set outside pressure testing glass reinforced plastic pipe, set inside steel drive end bearing bracket and rear end cap
Put the seal groove of cooperation so that be prone to hydraulic pressure deformation GRP pipe touch tightly during pressure testing be difficult to hydraulic pressure deformation
Steel enclosing cover, formed and reliably seal, the hydraulic pressure in pressure testing hydrospace is the biggest, and the connection of sealing ring and seal groove is tightr, close
Seal pressure is high.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of glass reinforced plastic pipe water test unit, including fixing seat 1, fixed support 2, drive end bearing bracket 3
And rear end cap 4, described fixed support 2 is arranged on described fixing seat 1, and described drive end bearing bracket 3 is hinged with described fixed support 2,
Pressure testing inner tube 6, one end of described pressure testing inner tube 6 and described drive end bearing bracket 3 it is provided with between described drive end bearing bracket 3 and described rear end cap 4
Fixing connection, its other end is detachably fixed with described rear end cap 4 by nut bolt structure and is connected, described drive end bearing bracket 3 and institute
State the pressure testing glass reinforced plastic pipe 5 that between rear end cap 4, installation is coaxial with described pressure testing inner tube 6, described pressure testing inner tube 6 and described pressure testing glass
Forming circular pressure testing hydrospace 7 between glass steel pipe 5, described pressure testing inner tube 6 is provided with vent valve 8, described vent valve 8 sets
