Description
Technical field：
The utility model is related to a kind of prefabricated whole box culverts, belong to assembled municipal works field.
Background technology：
Existing integral prefabricated box culvert, majority use prestressing force type of attachment, tube coupling to need to connect one by one after installation is complete
Point tensioned prestressing bar, connection type is complicated, and Engineering Speciality is strong, and cost is higher, and quality is not easy to control.Each tube coupling is to reach
The construction measures such as groove are arranged in waterproof purpose, tube coupling end, and mold complicated production cost is higher, and production efficiency is relatively low.Between tube coupling
It needs that waterproof sebific duct, item are arranged in advance, when component is stacked and is transported, be easy to cause destruction, easily cause to leak after the completion of construction
Water phenomenon, once there is leak, to remedy difficulty big, of high cost.Tensile materials are reinforcing bar in tube coupling, and tie point position by answering in advance
Power bar connecting, it is inconsistent due to tension effect, the stress concentration of tube coupling link position must be caused, destruction is be easy to cause,
Construction quality is influenced, security risk is in turn resulted in, influences the service life of box culvert.
Utility model content：
The purpose of this utility model is to solve existing integral prefabricated box culvert, and using prestressing force type of attachment, connection type is multiple
Miscellaneous, of high cost, quality problem not easy to control provides that a kind of structure stress is continuous, is not in answering for prestressing force type of attachment
Power concentration phenomenon extends the service life of box culvert, and speed of application is fast, and prefabricated components are high-quality, the prefabricated entirety of short construction period
Box culvert.
Above-mentioned purpose is realized by following technical scheme：
A kind of prefabricated whole box culvert, the box culvert include by exterior sheathing and be arranged inside the exterior sheathing one group
The cyclic structure that inner template is formed, between the exterior sheathing and the inner template between the two neighboring inner template
It is respectively arranged with one group of ring steel reinforced bar and is prefabricated into integral structure with the exterior sheathing and the inner template.
The prefabricated whole box culvert, the length of the inner template bottom are less than the length of the ring steel reinforced bar.
The described prefabricated whole box culvert is provided with a circle water-stopping steel between the inner template described in the exterior sheathing and one group
The length of plate, the steel plate for sealing water is less than the ring steel reinforced bar length.
A kind of connection method of prefabricated whole box culvert, this method comprises the following steps：Prefabricated whole box culvert completes
Afterwards, transport is to erecting bed, after the construction of live box culvert bottom cushion finishes and reaches mounting condition, hoisting prefabricated whole case section by section
Contain, ensure each angle installed height mark of whole box culvert both ends bottom plate and design position, ensures the gap of 2-4cm between each box culvert, it is adjacent pre-
Ring steel reinforced bar position between the whole box culvert of system is corresponding, and the ring steel reinforced bar structure of each box culvert both sides is identical, in two whole casees
Additional bar ring, the ring steel reinforced bar stretching of additional bar ring and two prefabricated whole box culverts are set between the ring steel reinforced bar section of stretching out of culvert
Section overlaps certain length respectively, and pin joint is inserted into the space that lap position is formed and indulges muscle and binds, in two whole box culvert gaps
Using gap between sealing strip and template two box culverts of closure, cast-in-place concrete, which reaches, between two box culverts is higher by the positions bottom plate 10-20cm,
The multiple connecting node concrete of continuous placing after concrete initial set, complete two box culvert nodes connection, then, carry out backfill and it is extensive
The processes such as multiple top road.
Advantageous effect：
1. the utility model provides a kind of prefabricated whole box culvert, it is used for municipal project, avoids " road slide fastener " problem, it will
It the centralized management of the professional facilities such as municipal administration gives, drains, electric power, communication, heat supply and safeguards.
The utility model solves the whole box culvert of prestressing force type of attachment, and connecting node is strongly professional, and linker is complicated,
Quality of connection such as is not easy to ensure at the disadvantages.
For the connecting node reinforcing bar of the utility model with arrangement of reinforcement inside tube coupling, either prefabricated tube coupling or connecting node are same
Poured for Reinforced Concrete Materials binding, structure stress is continuous, be not in prestressing force type of attachment stress concentration it is existing
As extending the service life of box culvert.
The utility model poured in place concrete amount is small, more traditional cast-in-place structural box culvert, template usage amount less 95% with
On, have speed of application fast, prefabricated components are high-quality, short construction period, small to existing traffic impact, come into operation morning, save
The many advantages such as construction cost.
The included integrated concrete blinding in the box culvert connecting node position of the utility model, connecting node cast-in-place concrete with
Precast concrete seam path is bent, and conducive to the waterproof that underground is constructed, coordinates the use of steel plate for sealing water, waterstop, waterproof effect
It is excellent.
The component installation of the utility model is simple, passes through additional circular reinforcing bar and pin joint bar connecting, component connection precision
It is required that it is relatively low, it is smooth vertical and horizontal between guarantee connecting elements.
The member profile of the utility model is simple, and corresponding production mould is simple, and each tube coupling form is identical, and mold repeats
Utilization rate is high, and die cost is low, and entire project cost is greatly reduced.
