Description
Technical field
The invention belongs to the water supply and drainage construction methods of architectural engineering, more particularly, to a kind of precast concrete well and steel band wave
The construction method of line pipe connection.
Background technique
Currently, rainfall and sewage pipes road and the connection of precast concrete well are close in the outdoor drainage engineering of Collapsible Loess District
The construction method of envelope is general are as follows: pre- on the borehole wall of prefabricated reinforced concrete well (abbreviation precast concrete well) when well room is constructed
Radial hole (abbreviation reserving hole) is stayed, one end section of rainfall and sewage pipes road (usually steel band bellows) is inserted into reserved
In hole, the connecting portion of the borehole wall of rainfall and sewage pipes road and precast concrete well fills real using waterproof mortar, in connecting portion
Concrete pack is arranged in outside；This method existing defects: first, waterproof mortar fills real not in place, and not can be carried out effective vibration
Construction is smash, easily there is gap, well room is caused to leak；Second, concrete pack setting only serves fixed function, not can guarantee waterproof
Quality.
Summary of the invention
The purpose of the present invention is to propose to a kind of encapsulating methods that precast concrete well is connect with steel band bellows, guarantee steel band
The sealing waterproof performance of bellows connection, improves construction quality, reduces construction cost, reduces the construction period, realizes quality and ring
Protect synchronous improve.
A kind of the object of the present invention is achieved like this: sealing side that precast concrete well is connect with steel band bellows
Method, it is characterized in that: after precast concrete well and steel band bellows (abbreviation bellows) installation (inserting) are in place, adjustment is fixed
Connecting portion between steel band bellows and precast concrete well, by the inside hole of the reserving hole on the precast concrete well borehole wall
It mouthful is blocked using baffle and support, then from the outside of the reserving hole on precast concrete well by free of contamination waterproof material
Steel band bellows, are finally located at the periphery waterproof at the medial and lateral hole of reserving hole by filling, the space for being tightly connected position
Mortar carries out shell nosing treatment.
A kind of encapsulating method that precast concrete well is connect with steel band bellows, construction procedure is:
One, adjust, the position of fixed precast concrete well and bellows, two, on the inside of reserving hole hole temporary plugging,
Three, waterproof material, four, waterproof mortar closing in, five, closed-water test, detection are filled.
Wherein:
One) it, adjusts, the position of fixed precast concrete well and bellows: (see Fig. 1)
After precast concrete well 1 is in place according to the absolute altitude installation of drawing, according to design, steel band bellows 2, this steel are installed
Right section with bellows 2 reserving hole put on 1 borehole wall of precast concrete well and the inner wall for stretching out precast concrete well 1 are adjusted
The position of whole precast concrete well 1 and steel band bellows 2 in reserving hole will close on the left-external side well of precast concrete well 1
One section of steel band bellows 2 on side take general bracket to be temporarily fixed, and reserve the outer of steel band bellows 2 in reserving hole
The space of the filling waterproof layer 5 on wall periphery.
Two), the temporary plugging at reserving hole inside hole: (see Fig. 1)
1), according to the diameter of the reserving hole on 1 borehole wall of the caliber of steel band bellows 2 and precast concrete well, steel is made
The baffle 3 of matter, the baffle 3 are the disc-shaped plate in arc surface, and the disc radius of the baffle 3 should be bigger than the radius of reserving hole
The ㎜ of 150mm~200,3 available thickness of baffle are made of the steel plate of 4 ㎜, the radius and precast concrete of the arc surface of the baffle 3
The inside radius of well 1 is consistent, opens up centre bore on baffle 3, the outer radius phase of the radius and steel band bellows 2 of this centre bore
Together, this baffle 3 is sleeved in the well inner end section of steel band bellows 2, while this baffle 3 is blocked on precast concrete well 1
Reserving hole inside hole on.
2), radial support 4 is installed in the inner cavity of precast concrete well 1, reinforcing is supported to baffle 3, the support 4
It can be made of the lumps of wood, which is respectively corresponded and is arranged on upper and lower, forward and backward four positions of 2 periphery of steel band bellows,
The vertical lumps of wood is added in left part positioned at two supports 4 in front and back of 2 periphery of steel band bellows, to enhance the reinforcing to baffle 3
Effect, meanwhile, while each support 4 is fixed using timber wedge.
Three) waterproof material: (see Fig. 1), is filled
Waterproof layer 5 is filled in the peripheral space of steel band bellows 2 in reserving hole, which is to use
Ordinary cement: asbestos: water according to (percentage) ratio: 1:4:0.5 is mixed and stirred, which divides five layers of filling to ram
It is real, using hand compaction, make tight between the reserving hole wall on steel band bellows 2 and precast concrete well 1.
Four), waterproof mortar closes up:
After waterproof layer 5 is filled, after conserving 2~3 hours, baffle 3 and each support 4 are removed, using logical
Outside portion of the waterproof mortar course 6 to the inside and outside hole for the reserving hole of steel band bellows 2 being located on precast concrete well 1
Position is sealed, and is then conserved according to conventional.
5), closed-water test, detection:
After waterproof mortar course 6 conserves qualification, using conventional method, to precast concrete well 1 and steel band bellows 2 according to
Section carries out closing water experiment detection, and whether observation precast concrete well 1 and the connecting portion of steel band bellows 2 have infiltration phenomenon,
Observation 30 minutes, no infiltration phenomenon, sealing are qualified.
The encapsulating method that precast concrete well proposed by the invention is connect with steel band bellows is reduced using reliable
The consumption and waste of sealing material, reduce construction cost, improve the effect of sealing waterproof.
