Abstract
The invention provides a steel die for prefabricating a concrete sewage inspection well, which comprises a die cavity I for forming a round base plate of a sewage inspection well and formed by the involution of two semi-circular arc plates I, wherein each semi-circular arc plate I is provided with an arc plate II coaxial with the semi-circular arc plate I with the same diameter and having a central angle less than 180 degrees; a side opening of each arc plate II is closed by a vertical plate in involution connection with the arc plate II; the vertical middle part of the inner surface of the vertical plate is provided with an arc surface which is coaxial with the arc plate II in involution therewith but differs by the wall thickness of a well body; and the arc plate II and the vertical plate are in involution to form a die cavity II for forming part of the well body of the sewage inspection well. By adopting the steel die for prefabricating the concrete sewage inspection well, the finished product of the standard component replaces field masonry, thus the dimensional accuracy of the product is improved; and moreover, the product has great bearing capacity and stable quality and is not easily damaged, thus the quality of the inspection well is effectively improved, and the quality problems of water seepage, cracking, collapse and the like of the inspection well caused by the heat expansion and cold contraction of the pipe of a brick sewage inspection well are thoroughly solved.
Description
technical field
The invention belongs to technical field of mold, relate in particular to a kind of precast concrete steel die for sewage inspection well.
background technology
Sewage inspection well is on sewerage system, to be check and clear up the inspection shaft that pipeline is set up, and also works the draught effect that connects pipeline section and pipe-line system simultaneously.At present, sewage inspection well mostly is the brick setting that standard brick and masonry of cement mortar form.Brick setting sewage inspection well, due to insufficient strength, there will be infiltration, crack, the phenomenon of even collapsing.Meanwhile, brick inspection shaft needs scene to build by laying bricks or stones, and speed of application is slow, and is easy to be subject to the impact of the many factors such as job site landform, construction environment, weather conditions, and site operation has a lot of uncertain existence, and this has had a strong impact on construction speed and construction quality.
summary of the invention
The technical problem to be solved in the present invention is to provide a kind of precast concrete steel die for sewage inspection well.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of precast concrete steel die for sewage inspection well, comprise by two involutory die cavity I that form moulding sewage inspection well circular shim of semi-circular arc plate I, in each semi-circular arc plate I, be located and the coaxial isometrical and arc II that central angle is less than 180 ° of this semi-circular arc plate I, the side opening of each arc II is by sealing with the riser of the involutory connection of this arc II, the vertical middle part of inner surface of riser has the arc II involutory with it coaxially but radius differs the arc surface of well bore wall thickness, the die cavity II of the involutory formation moulding of arc II and riser sewage inspection well part well bore.
Above-mentioned precast concrete steel die for sewage inspection well, described two arc II are oppositely arranged.
Above-mentioned precast concrete steel die for sewage inspection well, described arc II central angle is 90 °.
Above-mentioned precast concrete steel die for sewage inspection well, described arc surface has the protruding rectangular cross section stile to die cavity II.
Above-mentioned precast concrete steel die for sewage inspection well, described semi-circular arc plate I upper end cantilever support can form the arcuate member of one section of arcuate furrow near sewage inspection well circular shim top surface edge, arcuate member is two that are oppositely arranged, and is arranged between two risers and lays respectively at riser both sides.
Above-mentioned precast concrete steel die for sewage inspection well, is also provided with dismountable stull between described two risers.
Above-mentioned precast concrete steel die for sewage inspection well, the described involutory side flange by setting is connected realization with bolted.
Above-mentioned precast concrete steel die for sewage inspection well, is provided with arc reinforcement on the outer surface of described semi-circular arc plate I and arc II.
Above-mentioned precast concrete steel die for sewage inspection well, arranges horizontal bar on described riser outer surface.
Be the integral type precast concrete sewage inspection well that backing plate, top are well bore by die cavity I and die cavity II moulding bottom.By this cover punching block precast concrete sewage inspection well, build by laying bricks or stones with standardized member finished product replacement scene, improve product size accurate, and product bearing capacity is large, not fragile, steady quality, has effectively improved inspection shaft quality, has thoroughly solved brick setting sewage inspection well skirt material expand with heat and contract with cold inspection shaft infiltration, the crack of causing, the quality problems such as collapse.In addition, precast inspection well product size is accurate, steady quality, fast and manufacturing process of production cycle is not subject to the impact of field condition (as weather, geology), the work on the spot efficiency that has improved inspection shaft, has shortened construction period, has avoided that sewage closed-water test is defective cannot carry out next procedure, accelerate project progress, guaranteed construction quality.
accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the fractionation structural representation of Fig. 1.
In figure: 1 semi-circular arc plate I, 2 die cavity I, 3 arc II, 4 risers, 5 arc surfaces, 6 die cavity II, 7 rectangular cross section stiles, 8 arcuate members, 9 stulls, 10 arc reinforcements, 11 horizontal bars.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of precast concrete steel die for sewage inspection well, comprise by two involutory die cavity I 2 that form moulding sewage inspection well circular shim of semi-circular arc plate I 1, in each semi-circular arc plate I, be located and the coaxial isometrical and arc II 3 that central angle is less than 180 ° of this semi-circular arc plate I, the side opening of each arc II is by sealing with the riser 4 of the involutory connection of this arc II, the vertical middle part of inner surface of riser has the arc II involutory with it coaxially but radius differs the arc surface 5 of well bore wall thickness, the die cavity II 6 of the involutory formation moulding of arc II and riser sewage inspection well part well bore.
Particularly, described two arc II are oppositely arranged.
Particularly, described arc II central angle is 90 °.
The concrete sewage inspection shaft well bore of making by above-mentioned punching block has two relative reserved opening, be used for holding pipeline, in erecting bed, pipeline is placed in reserved opening place and uses Concrete Filled, tubing and xoncrete structure are integrated, improved the intensity of inspection shaft, and precast inspection well anti-permeability performance is good, has solved the defective series of problems causing of brick inspection shaft closed-water test.The integral installation of employing inspection shaft, has solved pipeline installation rate soon but the slow problem of inspection shaft speed of application has effectively shortened the duration.
