Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The invention provides a construction method of a circular inspection well template, which comprises the following steps:
the method comprises the following steps: and binding steel bars of the inspection well, pouring bottom plate concrete, and determining the side lines of the inner mold and the outer mold on the poured bottom plate concrete.
Step two: and building an inner mold 12 and an outer mold 11 of the brick molding bed according to the side lines of the inner mold and the outer mold. The brick die inner die 12 and the brick die outer die 11 are penetrated through by a drain pipe from the middle, the building height of the brick die inner die 12 and the brick die outer die 11 is determined according to the diameter of the drain pipe, and the two bricks need to be built above the top of the drain pipe to fix the drain pipe. Meanwhile, in order to prevent slurry leakage at the joints of the brick mould outer mould 11, the brick mould inner mould 12 and the drain pipe, mortar is required to be used for plugging the joints, so that the connection between the brick mould 1 and the drain pipe is sealed.
Step three: positioning an inspection well inner mold 21 side line at the top of the brick mould inner mold 12, wherein the inspection well inner mold 21 consists of two semicircular wood molds which are spliced together on a flat terrain to form a cylindrical inspection well inner mold 21, and brushing a stripper on the inspection well inner mold 21. Meanwhile, the cross bracing 41 is adopted to reinforce the inspection well internal mold 21, the cross bracing 41 is provided with adjustable threaded rod pieces, the cross bracing 41 is respectively arranged in the inspection well from top to bottom, and the threaded rods on the cross bracing 41 are adjusted, so that the cross bracing 41 and the cross bracing 4141 support the inspection well internal mold 21 at 4 fulcrums, and the inspection well internal mold 21 is reinforced. And (4) conveying the reinforced inspection well inner die 21 to the brick moulding bed inner die 12, wherein the inspection well inner die 21 is fixed to the brick moulding bed inner die 12 along the side line of the inspection well inner die 21.
Step four: according to the construction requirement, a concrete prefabricated strip with the same wall thickness as the wall thickness of the manhole chamber is selected, the prefabricated strip is attached to the outer portion of the inner manhole 21, and then the outer manhole 32 is wrapped on the outer portion of the concrete prefabricated strip. The inspection well external mold 32 is formed by splicing 4 arc-shaped modules, and a stripper is also coated on the inspection well external mold 32. After the manhole outer die 32 is used for coating the prefabricated strips, reinforcement treatment is performed on the outer portion of the manhole outer die 32.
And after the inspection well external mold 32 is fixed, checking and accepting the inspection well internal mold 21 and the inspection well external mold 32 according to the engineering specification, and performing the next step after the setting is confirmed to be correct.
Step five: and concrete is poured between the inner inspection well mould 21 and the outer inspection well mould 32, and the concrete and the prefabricated strips are solidified together to form the well wall of the inspection well under the positioning of the inner inspection well mould and the outer inspection well mould. After the concrete pouring is completed, the next step is performed after the concrete is completely solidified.
Step six: removing the reinforcement outside the inspection well external mold 32, detaching 4 arc molds of the inspection well external mold 32 from the inspection well, detaching the cross butt support 41 and the cross butt support 4141 inside the inspection well internal mold 21 from top to bottom, prying the staggered opening along the splicing part of the inspection well by using a crowbar after detaching the cross butt support 41 and the cross butt support 4141. The detached arc-shaped die and the half-round wood die can be reused.
Compared with the traditional mode of adopting a shaped steel die or a narrow strip wood die to pour the inspection well, the construction method provided by the embodiment greatly reduces the construction difficulty, the mode of combining the inner die and the outer die of the inspection well with the brick bed mould 1 improves the construction effect of the inspection well, the template can be repeatedly utilized, the construction cost is reduced, meanwhile, the construction method is high in construction speed, the construction period is shortened, and good social benefits and economic benefits are achieved.
In one embodiment of the invention, the heights of the inner brick molding bed 12 and the outer brick molding bed 11 are higher than the height of the pipeline by more than 30cm, so that the drain pipe is fully wrapped by the brick molding bed 1 and protected. And simultaneously, mortar is used for plugging joints of the inner mold 12 of the brick molding bed, the outer mold 11 of the brick molding bed and the pipeline. Preventing the slurry leakage.
In one embodiment of the present invention, in step three, the manhole inner mold 21 is formed by splicing two semicircular wood molds into a cylinder. The semi-circular wood formers are manufactured according to the size of the inspection well to be built, and the two semi-circular wood formers are spliced together to form a cylinder for supporting and shaping the interior of the inspection well.
In one embodiment of the present invention, the cross brace 41 and the cross brace 4141 are fixed with the arc plate 42 at the end, and the arc of the arc plate 42 is matched with the semicircle wood pattern. The cross counter support 41 and the cross counter support 4141 respectively abut against the splicing part of the two semicircular wood formers and the middle part of the semicircular wood formers. The arc plate 42 of setting can laminate to the semicircle wood pattern on, enlarges the support area to the semicircle wood pattern, makes the support that the semicircle wood pattern received more even, non-deformable. .
In one embodiment of the present invention, the manhole outer mold 32 and the manhole outer mold 3232 are externally reinforced by steel hoops 31. When the 4 arc-shaped molds are positioned and decocted on the concrete prefabricated strip, the concrete prefabricated strip is wrapped by the steel hoop 31, the tightness of the steel hoop 31 is adjusted by screwing the screws on the steel hoop 31, the screws are screwed, so that the arc-shaped molds tightly clamp the concrete prefabricated strip, and the deformation of the inspection well external mold 3232 of the inspection well external mold 32 is effectively controlled.
In one embodiment of the invention, a concrete setting period not less than 24 hours needs to be reserved between the fifth step and the sixth step, so that the poured inspection well is ensured to be sufficiently set, and collapse caused by insufficient setting is avoided.
In one embodiment of the invention, after the inner mold 21 of the inspection well is removed, the inner mold 12 of the brick mould is chiseled. After the inner mold 12 of the brick molding bed is removed, the outer mold 11 of the brick molding bed can be reserved according to the actual situation and the use requirement.
In one embodiment of the invention, after the concrete is poured in the fifth step, the concrete is vibrated by a vibrating rod. The vibration elimination of the vibrating rod prevents the foaming in the poured concrete, and prevents the honeycomb pitted surface from appearing inside the well wall, thereby preventing the strength of the well wall from being influenced.
In an embodiment of the invention, after the outer inspection well mold 32 and the inner inspection well mold 21 are removed in the sixth step, the surface of the inspection well is maintained by covering with a thin plastic mold. The surface of the concrete is sealed by an anti-evaporation material, so that the water in the concrete is prevented from evaporating, the concrete is kept or close to a water saturation state, and the normal operation of the hydration reaction of the cement is ensured.
