Abstract
The utility model provides a leading slip casting ductule construction equipment of tunnel, including loop bar (2), sleeve (1) and backing plate (3), the one end in loop bar (2) is overlapped in sleeve (1), and backing plate (3) are overlapped below sleeve (1), during the construction insert the device the tail end of slip casting ductule. The processing of this device is simple and convenient, can dismantle in the construction, and reuse is assembled at the scene. Taking in the work progress and tearing open portably, safe practical, the construction efficiency is high, with low costs. And can guarantee that the installation of slip casting ductule is once successful, be applicable to the slip casting ductule construction and installation of soil cave section.
Description
Technical field
This utility model belongs to engineering construction field, specifically a kind of tunnel grouting small pilot pipe constructing device, is suitable for
In the section slip casting ductule construction of soil property hole.
Background technology
Subterranean tunnel slip casting ductule advance support, is often mud horsestone or full soil poor geological region, and construction first adopts handss
Air drill drills, then installs slip casting ductule.Due to features as poor geologic condition, generally rich groundwater, easily collapse hole bit freezing, slip casting
Ductule installation success rate is low, difficult during installation to reach bottom hole.Traditional slip casting ductule pore-creating is carried out using handss air drill, is pacified after pore-forming again
The dress slip casting ductule body of rod, due to often showing as native clitter product or loose earth, peace using slip casting ductule advance support hole section
Easily collapse hole during dress slip casting ductule, need again or repeatedly cleaning bottom of hole, affect work efficiency and destruction Rock Slide Stability.
Utility model content
The purpose of this utility model is to provide a kind of tunnel grouting small pilot pipe constructing device, to improve slip casting ductule
Success rate is installed, it is ensured that slip casting ductule pore-creating, installation one-shot forming, it is to avoid country rock is repeatedly disturbed, and improves slip casting ductule
Construction efficiency, it is ensured that construction is fast and safely.
To ensure slip casting ductule installation quality, this utility model reference self-feeding anchor pile construction technology, with " heading into method "
The impact of slip casting ductule handss air drill is headed into the soil body by operation.By field test, well-designed this practicality of technical staff is new
The tunnel grouting small pilot pipe constructing device of type.
Concrete structure is：Tunnel grouting small pilot pipe constructing device includes loop bar, sleeve and backing plate, and sleeve is enclosed within loop bar
One end, backing plate is enclosed within below sleeve, and the device is inserted during construction the tail end of slip casting ductule.
During construction, the device is inserted after the tail end of slip casting ductule, then note is headed into in country rock body after covering air drill of starting with
Slurry ductule, to design hole depth stops top punching, removes handss air drill and extract the device rod member, then carry out next hole construction,
The successful effect of slip casting ductule once mounting is reached.
Subterranean tunnel of the present utility model heads into the constructing device of slip casting ductule, and simple processing is detachable in construction, existing
Assembled material can be reused, can flexible combination, take and tear easy, safe and practical open, turnover utilization rate is high, it is adaptable to mollisol
The construction of matter, can reduce the hole that collapses, accelerating construction progress, efficiency of construction height, low cost, and can guarantee that slip casting ductule is installed once
Success, improves slip casting ductule and installs success rate, it is adaptable to the slip casting ductule installation of soil cave section.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is construction operation schematic diagram；
Reference：1- sleeves, 2- loop bars, 3- backing plates, the hand-held handss air drills of 4-, 5- slip casting ductules.
Specific embodiment
As shown in figure 1, tunnel grouting small pilot pipe constructing device of the present utility model includes loop bar 2, sleeve 1 and backing plate
3, sleeve 1 is enclosed within one end of loop bar 2, and backing plate 3 is enclosed within below sleeve 1, and the device is inserted during construction the tail of slip casting ductule
End.
This device using steel make, set shank diameter match with handss air drill bayonet socket bore, sleeve, the thickness of backing plate and
The visual practical situation processing of planar dimension, builder's staging are fixed using detachable scaffold clasp, can guarantee that slip casting is little
Conduit installs once success, it is adaptable to the slip casting ductule installation of soil cave section.
During construction, as shown in Fig. 2 operating personnel's specific implementation step is for example following：
Step 1：First drilling rod is inserted in handss air drill, in slip casting ductule hole position draw hole depth to direction " drawing hole " by hole
For 3～5cm, it is beneficial to slip casting ductule and heads into.
Step 2：Drilling rod is transferred to, slip casting ductule guide head is inserted in " drawing hole ", along slip casting ductule hole to a people
Slip casting ductule is held up in front end, device insertion slip casting ductule end will be headed into.
Step 3：Air drill of starting with is covered device end is headed into, the tight handguard air drill of a people, a people hold in the palm steady slip casting ductule, open
Rig trigger valve, is impacted into the soil body by the angle of regulation and heads into slip casting ductule.
Step 4：Steady slip casting ductule is held in the palm during heading into, prevents the slip casting ductule body of rod sagging, to ensure that Kong Xiangcheng is straight
Line, at the uniform velocity slow-motion during jacking, to reduce the disturbance to the soil body.
Step 5：After slip casting ductule is rushed to summit in place, rig trigger valve is closed, remove handss air drill, dial-out heads into device, enters
The construction operation in the next hole of row.
