Abstract
The invention relates to a prefabricated reinforced concrete box culvert which comprises a box culvert body, wherein a bell mouth is arranged at one end of the box culvert body; a socket is arranged at the other end of the box culvert body; a steel ring is sleeved outside the bell mouth end; and a flexible sealing interface which extends outward from a clearance between an inner circle of the steel ring and an outer circle of the bell mouth end is arranged between the inner circle of the steel ring and the outer circle of the bell mouth end. According to the invention, the interface of the prefabricated reinforced concrete box culvert is designed as a steel bell mouth, the interface is flexibly sealed by a rubber ring in the steel bell mouth, and the flexible connection of box culverts is realized in the manner of flexibly sealing the interface; sealing elements, such as an expanding rubber ring, a sealing plaster slot, and the like, can be added according to different demands on sealing property, so that the prefabricated reinforced concrete box culvert is suitable for different environments; and compared with the traditional box culverts in rigid connection, the prefabricated reinforced concrete box culvert has the advantages that the sealing property of a prefabricated reinforced concrete box culvert pipeline is promoted, the pipeline is undamaged during a long-term running process when a foundation settles unevenly, and the safety of the pipeline running is increased.
Description
Technical field
The invention belongs to the design that relates to connecting interface in the underground assembling concrete box culvert pipeline, belong to the conduit coupling technical field.
Background technology
The municipal public use pipeline of China mainly is to use concrete pipe, has: raw material are cheap, production is simple, and price is low; Concrete pipe rigidity is big, in the reciprocal pressure process of vehicle, does not produce distortion, can not destroy the functional performance of pavement of road function; Concrete products is a low energy consumption of low pollution product, environmental sound; The concrete products good endurance, service life is long.
The box-shaped RCCP is also referred to as square RCCP (abbreviating " box culvert " or " Fang Han " as), because of its pipe section is shaped as rectangle or square gaining the name.
The box-shaped pipeline can reasonably be adjusted the width and the height of box culvert according to the terms and conditions such as geographical environment of engineering, satisfies the traffic requirement of pumped (conveying) medium and reasonably takies the underground space.And the pipeline of circular cross section does not possess such advantage, and in large-scale underground pipeline, under the equal flow condition, circular pipe is compared with the box pipeline, can take more space, more cubic metre of earth of excavation.
As the sleeve pipe of municipal public use pipeline, as using box culvert, because of section in it is that straight wall is square, mounting bracket on sidewall, discharging cable or pipelines such as feedwater, heating power, simple and convenient, space availability ratio is high.
Because box culvert has these unique advantages, along with the growth of national power, box culvert more and more is widely used.
Box culvert is developing product in China, also exists not enough.Become pipeline such as connecting into integral body in the construction of prefabricated reinforced concrete box culvert, mostly the interface that former box culvert connects is that flat mouthful the connection of rigidity or the tongue and groove of rigidity connect.
What the bonding pad of flat shape of the mouth as one speaks interface or tongue-and-groove type interface used is cement mortar filler, expansive cement filler or asbestos cement filler; These three kinds of fillers all are rigid filled; When relative displacement or corner took place between box culvert, interface was broken into two with one's hands, airtight and watertight padding is by drawing crack, and sealing is damaged; The line transportation medium is from interface generation seepage, and the function of use of pipeline is affected.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide between a kind of box culvert through flexibly connecting the prefabricated reinforced concrete box culvert that forms pipeline.
The technical scheme of the present invention's employing is for this reason: the present invention includes the box culvert body; One end of said box culvert body is established bellmouth, the other end is established socket; Said female end is arranged with one one outward and is in the outer steel ring of female end, establishes the flexible sealing interface that extends outward from both gap locations between circle and the female end cylindrical in the said steel ring.
The outer ends of said flexible sealing interface is within the steel ring outer end.
The junction of circle and socket cylindrical is provided with the expansion cushion rubber in the said bellmouth.
The junction of circle and socket cylindrical is provided with the lute in groove in the said bellmouth.
The aprons slot that cushion rubber is installed is established in said socket end.
The reinforcement steel ring of protrusion is established in said socket end.
Advantage of the present invention is: the present invention becomes the steel bellmouth to the Interface design of prefabricated reinforced concrete box culvert, in the steel bellmouth, adopts rubber ring flexible sealing interface, realizes flexibly connecting of each box culvert through the flexible sealing interface; And the present invention can increase seals such as expansion cushion rubber and lute in groove, so that the present invention is applicable to the use of varying environment according to the demands of different of sealing performance; The present invention compares being rigidly connected of traditional box culvert, improved prefabricated reinforced concrete box culvert pipeline sealing, allow pipeline in the long-time running process, pipeline is not destroyed during ground generation differential settlement, has improved the safety of pipeline operation.

Fig. 5,6,7, the 8th, the bellmouth sketch map of the various form of structure of the present invention.
1 is that socket, 2 is that bellmouth, 3 is that steel ring, 4 is that aprons slot, 5 is that expansion cushion rubber, 7 is the lute in groove for strengthening steel ring, 6 among the figure.
The specific embodiment
As shown in Figure 1, the present invention includes box culvert body and bellmouth that is arranged on box culvert body both sides 2 and socket 1, said bellmouth 2 comprises the steel ring 3 of indent, steel ring 3 places are arranged with the flexible sealing interface that fits tightly with steel ring 3, said socket 1 and said bellmouth 2 correspondences.
Like Fig. 2, Fig. 3, several kinds of socket forms shown in Figure 4: wherein socket shown in Fig. 21 is the socket of band aprons slot 4, and 1 end of socket shown in Fig. 3 is equipped with steel stiffening ring 5, and socket shown in Figure 5 is the slope shape interface.
Like several kinds of steel bellmouth forms shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8 are: water-swellable cushion rubber 6 and lute in groove 7 are installed on steel bellmouth 2 interfaces shown in Figure 5; 2 of steel bellmouths shown in Figure 6 are installed lute in groove 7; Steel bellmouth shown in Figure 7 is only installed water-swellable cushion rubber 6, and shown in Figure 8 is that steel bellmouth 2 interfaces are not installed water-swellable cushion rubber 6 and lute in groove 7.Impervious seal request according to requirements for pipes can be selected multi-form steel bellmouth respectively for use.
