There are two, 32 interconnection of the first positioning beam 31 and the second positioning beam is played and starches what sleeve body 1 was limited and fixed to seat
Effect, while also reinforcing the structural strength of concrete.
Specifically, the first positioning beam 31 and the second positioning beam 32 are respectively set two, the first positioning beam 31 is longitudinal to be extended, the
Two positioning beams 32 are laterally extended, and the first positioning beam 31 is intersected with 32 transverse and longitudinal of the second positioning beam, and is welded and fixed, the first positioning beam
31 and second positioning beam 32 be also welded and fixed in present slurry sleeve body 1, simple installation.
Further, seat slurry, grafting longitudinal reinforcement 5 in locating groove 2, the choosing of seat slurry are filled in seat slurry sleeve body 1
With Special stand slurry, first longitudinal reinforcement 5 is inserted into locating groove 2, then will be in Special stand slurry filling seat slurry sleeve body 1.
Seat slurry sleeve body 1 is fixed in piping lane bottom wall 6, is equipped with transverse steel 7 in piping lane bottom wall 6, locating rack 3 and laterally
Reinforcing bar 7 is welded and fixed, and realizes the fixation to seat slurry sleeve body 1；In seat slurry sleeve body 1 after grafting longitudinal reinforcement 5, it is poured seat
Slurry realizes the positioning to longitudinal reinforcement 5, to be poured piping lane interior wall 4.
One preferred embodiment of the construction method of pipe gallery of the invention, constructs in accordance with the following steps,
Step 1 prepares material, including seat slurry, seat slurry sleeve, connection reinforcing bar；
Step 2, sets up template, assembling reinforcement, and seat starches sleeve body welding positioning, the hole protection of locating groove；
Step 3, base plate member pour, maintenance；
Step 4, upper reinforcement are inserted into the hole of locating groove, reinforcing bar contraposition, and wall is installed, and wall is fixed；
Step 5, the configuration of Special stand slurry, fluidity inspection；
Step 6, grouting hole seat slurry.
Wherein, seat slurry uses quick-hardening cement, and the preferably materials such as graded aggregate, slurry thixotroping improvement and hole regulation are prepared
Seat slurry, be able to satisfy the required mobility of seat slurry, crack resistance, impermeability, micro-expansibility energy, cohesiveness and can reach
It is required that intensity, further promote pipe gallery construction quality and construction efficiency.
Slurry thixotroping, which improves material, can select inorganic thixotropic agent or organic thixotropic agent, such as clay mineral class, sulfuric acid
The chelates such as salt, metal carbonate or mixed metal hydroxides or triethanolamine titanium.
Galvanized metal bellows is the metal bellows product produced using galvanized steel strip by rolling, due to adopting
With above-mentioned galvanized steel strip, there is good antiseptic property, is more contacted compared to having for general black steel band
Anti-corrosion and antirust ability.
When by piping lane interior wall bottom reinforcement bars insertion seat slurry sleeve body, ungauged regions seat slurry is filled into seat slurry sleeve sheet first
Body reaches one to ungauged regions seat slurry then by the locating groove of the reinforcing bar insertion seat slurry sleeve body of piping lane interior wall bottom
When determining intensity, wall connecting is completed.
For seat slurry sleeve body using the zinc-plated bellows of back cover and reserved steel bar hole, slurry sleeve body of being present and base plate member are logical
Positioning device connection is crossed, by the way that locating groove is arranged, starches sleeve body being fixedly connected in the production phase convenient for seat.
Bar spacer slot is arranged in present slurry sleeve body bottom, solves that reinforcing bar is unable to rapid-aligning, component is equipped with
The problem of deviation.
The structure of seat slurry sleeve of the invention overcomes the tired of delay-pour joint complex process at conventional sleeve connection or node
Difficulty is inserted into piping lane interior wall reinforcing bar by being first perfused after ungauged regions seat slurry, the connection between completion reinforcing bar and seat slurry sleeve body,
The joint efficiency of piping lane component is improved, and reduces the cost of production.
Further for the reinforcing bar of different-diameter, seat starches the length of sleeve body and of different sizes.
In order to reinforce the intensity of base plate member, bottom plate longitudinal reinforcement is additionally provided in base plate member.
Preferably, seat starches the tapered construction of sleeve body, and base diameter is greater than upper diameter, enhances sleeve and coagulation
Bond effect between soil, strengthens the connection extraction-resistant behavior of reinforcing bar and sleeve, and seat slurry sleeve body can also use zinc-plated
Bellows production.
The seat slurry sleeve body of reinforcing bar connection uses the zinc-plated bellows with back cover, adds on the back cover of zinc-plated bellows
If locating groove, reinforcing bar is inserted into locating groove.When construction, zinc-plated bellows is connect with piping lane bottom wall by locating rack.Construction
When, it needs to carry out the safeguard measure of pore before casting concrete, concrete is avoided to enter in pipe, ungauged regions Special stand slurry is infused
It has a full house and starches sleeve body, (wherein, the intensity of 1 day age of seat slurry not preferably less than 25MPa, the intensity of 28 day age is not preferably less than
60MPa), then wall is completed when seat slurry reaches intensity and is connected by the locating groove of upper wall body reinforcing bar insertion seat slurry sleeve
It connects.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
