Description
Technical field
Stake, which is poured, the present invention relates to precast concrete mends slurry technical field of construction, it is especially a kind of novel for Composite Bolt
The benefit paste-making method and device of stake.
Background technique
At present when bridge, tunnel pour, often (tube wall and pipe end offer the one of through-hole to pre-buried benefit slurry pipe inside it
Root long pipe), the pre-buried effect for mending slurry pipe is on the one hand to promote the entire compression of bridge using slurry pipe is mended as the skeleton of bridge
Property, on the other hand slurries can be poured into inside benefit slurry pipe by grouting pump after bridge concrete placings, slurries are under pressure
By mend the injected hole that opens up on slurry pipe flow through between bridge wall and tube body because concrete generates gap caused by bubble
In, so that gap filling is improved the degree of packing of concreting, it then will mend in slurry pipe again and fill slurries, improve bridge
Pouring quality.
Nowadays there is drawback using when mending slurry pipe progress slip casting:
1) length for mending slurry pipe itself first is longer, and during slurry stream warp, resistance can be generated to slurries by mending slurry tube wall, from
And the slurries flowing velocity injected can slow down；And when the slurries for mending slurry tube end fill, slurries can generate reflux, to injection
Slurries cause further resistance, the slurries of confluence when passing through injected hole, can not by grouting pump pressure act on
Into grouting port, the injection process of slurries can only be caused by the gravity overflow of itself into the gap between wall and tube wall
Slowly, at the same mend slurry manage each position slip casting uniformity it is poor, influence grouting quality.
2) simultaneously according to the characteristic for the injected hole aperture for mending slurry pipe itself, injected hole is located at surrounding and the end of tube wall, infuses
When slurry, when slurries are flowed out from bridge beam gap, it was demonstrated that the slurries in gap have filled up, and due to note during slip casting
Slurry hole is that the tube wall surrounding for mending slurry pipe is evenly distributed on along axle center, and when slip casting, the slurries for causing the injected hole of front end to inject are mentioned
It is preceding to be flowed out from the gap of bridge, it has been filled up so that people be allowed to be mistakenly considered gap, and stop slip casting, gap is not filled actually,
Slip casting mistaken ideas are caused, causes slip casting incomplete, influences grouting quality.
3) current slurry injection technique (using pressure pump toward the interior slip casting of pre-buried benefits slurry pipe, not assisting the device of slip casting) is more
Single, functional poor, the slurry flow rate in slip casting end is unstable, and slip casting effect is poor.
Based on this, the novel benefit paste-making method and device for Composite Bolt stake of one kind is needed to solve to exist in the prior art
The problem of.
Summary of the invention
