Abstract
A kind of precast inspection well reserved opening circular apparatus, including pipe and supporting rack, support frame as described above is set in pipe, and supporting rack is connected by two reinforcing bars in right-angled intersection, screw hole is respectively equipped at the tie point of two reinforcing bars, bolt is connected and fixed also cross after the screw hole of two reinforcing bars by nut.When the utility model is used for casting concrete, it is used as opening mould plate, has certain rigidity；Holder is used to fix pipe, and pipe is made to keep firm, convenient for disassembly and assembly.The device is easy to process, stability is good, it is easy to operate, repeatable utilize, concrete forming works well, greatly improve reserved opening Pipe installing antiseep effect, improve work efficiency, entrance construction is connect with pipeline suitable for precast inspection well.
Description
Technical field
The utility model is related to a kind of precast inspection well reserved opening circular apparatus, especially a kind of to be suitable for precast construction
The midget plant of template-setup at object reserved opening.
Background technology
Reserved opening formwork construction often has common quality defect in armored concrete precast inspection well work progress.It is traditional pre-
Inspection shaft reserved opening construction processed is clogged with geotextiles or fired brick is piled up, and easily causes hole to seep water with pipeline junction and leaks
Water, the common quality defects such as reserved opening cavity, pitted skin, poor, the dimension of opening deviation of appearance.Also, reserved opening construction quality is good
It is bad to be closely related with whether pipeline junction leaks with precast inspection well.Dimension of opening and shape influence inspection shaft reserved opening with
Gap size when pipeline connects, it is big to fill up difficulty when gap is excessive, easily junction is caused to leak.
Invention content
The utility model aim is the shortcoming that overcome in existing working measure, provides a kind of reserved opening size conjunction
Preferably, highly practical a kind of precast inspection well reserved opening circular apparatus.
To achieve the above object, technical solution provided by the utility model is：A kind of precast inspection well reserved opening is round
Device, including pipe and supporting rack, support frame as described above are set in pipe, and supporting rack is connected by two reinforcing bars in right-angled intersection,
The connection of two reinforcing bars, which is pointed out, is respectively equipped with screw hole, and bolt is connected and fixed also cross after the screw hole of two reinforcing bars by nut.
The pipe is made by PE pipes.
The pipe length is longer than the depth of reserved opening, and the pipe outer diameter is slightly larger than reserved opening diameter.
Setting supporting rack is bearing coagulation during precast inspection well casting concrete in the pipe of the utility model
Without being deformed while soil dead weight generates downwards extruding, and the reserved opening lines of forming is made to keep mellow and full.
Advantageous effect：It is even closer that the utility model can be such that precast inspection well reserved opening is connect with pipeline junction, with
Traditional reserved opening construction is compared to more time and labour saving, and easy for installation, effect is more preferable.It has the following advantages that：
（1）Simple structure, it is easy to use, it can voluntarily process, and can repeat to construct.
（2）Installing and dismounting is simple, which is connected with, i.e., dress is torn open, time and labour saving, economy.
（3）Prefabricated component inspection shaft reserved opening after molding is uniform with pipeline junction gap and gap is smaller, convenient for using
Mortar is filled up, and antiseep effect is preferable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is sectional schematic diagrams of the Fig. 1 when precast inspection well is constructed.
Specific implementation mode
The utility model will be further described for embodiment in below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, the precast inspection well reserved opening circular apparatus of the utility model, including pipe 1 and supporting rack
2, support frame as described above is set in pipe, and supporting rack is connected by two reinforcing bars in right-angled intersection, and the connections of two reinforcing bars is pointed out point
Not She You screw hole, bolt is connected and fixed also cross after the screw hole of two reinforcing bars by nut.Wherein pipe 1 through PE pipes process and
At outer diameter is more bigger than inspection shaft reserved opening caliber, and length is more each stretching 20cm than prefabricated well barrel thickness both ends.Supporting rack 2 is by two
25 steel bar meters of root Ф form, and are fixed in pipe by bolt and nut 3.Bolt and nut 3 is solid for Steel bar rack when installing
Calmly, Steel bar rack loosens when dismounting.
Working method and principle：Step 1：After precast inspection well template installs, the pipe of machine-shaping is put into
In template reserved opening, so that template edge is contacted with pipe and be close to well.Step 2：Steel bar rack is put into pipe, and shape
At " cross " shape.Step 3：Connecting bracket nut is tightened, pipe is supported firm.Step 4：Concrete dismounting to be achieved
Nut is unscrewed after intensity, unloads reinforced bar support and pipe, is reused next time.
