Description
Technical field
The present invention relates to prefabricated steel concrete manhole system.
Background technology
For implementing a scientific outlook on development and adhering to resource-effective theory; The ban of forbidding loam brick without exception about all cities in 2010 according to nation-building portion, the Committee of Development and Reform, Ministry of Land and Resources, four ministries and commissions of the Ministry of Agriculture; And " about in town road is built, progressively eliminating the notice of brick formula manhole " spirit is assigned by Hefei City's in April, 2011 town and country capital construction commission; My scientific research personnel of company organization, a line technical backbone in production; Prefabricated steel concrete manhole is produced in research and development, and succeeds in developing in March, 2012.This product design is beautiful, structure is excellent, intensity is high, anti-leakage is strong, compliance is extensive.Product has used proof in engineering, operation is simple and easy when construction, installation is fast, the time and labour saving, and each item technical indicator all satisfies the national building standard requirement.
Summary of the invention
The purpose of this invention is to provide prefabricated steel concrete manhole system, assembled steel reinforced concrete inspection well is built formal check well construction more convenient and quicker by laying bricks or stones than other, and resistance to overturning is better; Intensity is higher; Impermeability is stronger, and cost is low, the outstanding mature production technology of rolling; Producing flexiblely, is to substitute other to build the ideal product of formula manhole by laying bricks or stones.
Technical scheme of the present invention is following:
Prefabricated steel concrete manhole system; Include well chamber, well closing in section, pit shaft, walling crib; It is characterized in that: lower end, well chamber employing tenon tongue-and-groove grafting base plate, upper end, well chamber and well close up and adopt the tenon tongue-and-groove to be plugged with well chamber regulating block between the section, adopt the tenon tongue-and-groove to peg graft between the upper end of the lower end of pit shaft and well closing in section; Adopt the tenon tongue-and-groove to be plugged with the pit shaft regulating block between pit shaft upper end and the walling crib lower end; The upper end of walling crib is equipped with well lid, leaves hole for hoist respectively on well chamber, well closing in section, pit shaft, walling crib, well chamber regulating block, the pit shaft regulating block, and pit shaft, well leave pipe joint on the chamber.
Described well chamber and well close up, and interface is provided with the watertight rubber circle between the section.
Compared with present technology, beneficial effect of the present invention is following:
1, good integrity.Manhole base plate, well chamber, the big tongue and groove flexible interface connection of employing (placing the watertight rubber circle in the tongue and groove) between section, the pit shaft of closing up; Regulating block also adopts big tongue and groove flexible interface to connect between the well chamber, between pit shaft; The manhole base plate also can use the groove type interface to be connected with the well chamber; Fill with the 1:2 waterproof cement mortar, the manhole resistance to overturning is good.
2, save time, the saving of labor.Because easy construction is quick, has saved the engineering time, has accelerated construction speed.Minimum needs of the manhole in-place forming time that common brick is built by laying bricks or stones are more than 2 days, and the minimum needs of concrete building block manhole are more than 1 day, and prefabricated steel concrete manhole only needs 2 hours, saves a large amount of artificial simultaneously.
3, the inside and outside borehole wall need not to whitewash.The outside gets final product with the jointing of 1:2 waterproof cement mortar in only needing.
4, adopt big tongue and groove step tenon, tongue-and-groove kiss connection interface (placing the watertight rubber circle in the tongue and groove).The water shutoff performance is good, and is impervious strong.
5, intensity is high, and cost is low.Since adopted the prefabricated production technology of batch production, stream curing, the roll welding reinforcing bar, shaft bottom plate, well chamber, the section that closes up, pit shaft design concrete strength reach design standard C30, and its cost is lower than concrete building block manhole.
6, be applicable to airport, square, park, building sub-district, general industry and municipal drainage engineering.
7, low-carbon (LC), environmental protection.Produce, use assembled steel reinforced concrete manhole can save limited land resources and run off, need not to use coal and clay resource, belong to the green building material product.
Three, the specification of prefabricated steel concrete manhole and index
1, strength grade of concrete>=C30, impervious grade>=S6, maximum water/binder ratio are 0.5, and minimum cement dosage is 300kg/m3, and maximum chloride ion content 0.1%, maximum alkali content are 3.0 ㎏/m
3
2, longitudinal stress reinforcing bar and helical ring muscle adopt HRB400 level hot-rolled reinforced bar, and stirrup adopts HRB335 level hot-rolled reinforced bar.The longitudinal stress reinforcing bar adopts φ 8, and the helical ring muscle adopts φ 8, is double-layer double-direction.Shaft bottom slab muscle adopt φ 10HPB235 level hot calendering round bar with
φ12HRB335 level hot-rolled reinforced bar adds ring muscle and stirrup and is linked into an integral body with the base plate reinforcing bar on the base plate tongue and groove.The hoisting ring reinforcing bar adopts HPB300 level φ 12 hot calendering round bars respectively.
3, Minimum Concrete Protective Coating Thickness: well chamber base plate lower floor muscle and cover plate lower floor tendon protective layer are 40mm, and other positions are 35mm.
4, manhole wall thickness 15cm; Base plate thick 10cm in well chamber establishes the high steel bar concrete annular of 10cm tongue and groove on the base plate of well chamber, adopt 4 φ, 8 plain bars and connect into an integral body with stirrup and base plate reinforcing bar, and this interface is again a little outrigger of annular.Both save material, alleviated base plate weight again, and stressed better, strengthened base plate entire compression intensity, strengthened trust, the interface of satisfying socket purposes is arranged, better effects if.
