Abstract
The invention relates to a construction method for connection part of a bridge lapping slab and a cement stabilized base. In the prior art, since a cement stabilized base and the like are constructed generally after a bridge lapping slab is poured, a blind grinding area exists at a connection part between the bridge lapping slab, especially a sawtoothed lapping slab, and the cement stabilized base, thus influencing the construction quality. The construction method comprises the following steps of: first, paving and grinding the cement stabilized base, and excavating the end of the cement stabilized base at one side of the lapping slab, thus forming a toothing part corresponding to the toothed end of the bridge lapping slab; and finally pouring the bridge lapping slab so as to correspondingly match the cement stabilized base with the toothed end of the bridge lapping slab. Therefore, the compactness and flatness at the connection part of the bridge lapping slab and the cement stabilized base can be guaranteed, soil and/or water and the like at the lower part of the cement stabilized base can be effectively prevented from exuding from the connection part, and sinking of the lapping slab at the connection part and premature damage of a road surface due to loosening of the base and the like can be prevented, so that the construction quality of the road can meet the design requirements and the driving comfortableness and safety can be ensured.
Description
Technical field
The present invention relates to the job practices of a kind of bridge attachment strap and the steady basic unit of water junction
Background technology
Estimate the service property (quality) and the service quality of a highway, a very important evaluation criterion is exactly whether end of the bridge has the car of jumping phenomenon.It is meant that the nature road surface deformation, fracture even hole groove occur with the zone that is connected of the bridge platform back of the body, thereby makes vehicle ' be subjected to impacting the phenomenon that the back generation is obviously jumped, jolted through this zone.The bumping at bridge-head phenomenon not only has a strong impact on the comfortableness of driving, also can reduce the travel speed of vehicle and the traffic capacity of road, even can cause road traffic accident.How resolving problem of bumping at bridge-head, is a lot of highway designs and the problem that the builder is paid close attention to, effective attachment strap wherein is set behind abutment, and attachment strap is connected well with natural road, and be an important measures.
In the prior art, bridge attachment strap 1 ' all is designed to zigzag (as shown in Figure 1) usually with the junction of the steady basic unit 2 ' of water, be to build bridge attachment strap 1 ' earlier during construction, re-lay and roll the steady basic unit 2 ' of water, this makes the bridge attachment strap 1 ' and the toothed area 3 ' of the steady basic unit of water 2 ' junction be difficult to be rolled (promptly exist and roll the blind area), cause the toothed area degree of compaction between the steady basic unit of bridge attachment strap and water not meet design requirement, even the hole appears, the steady basic unit of bridge attachment strap and water can not fully link, and influences construction quality
Summary of the invention
Technical problem to be solved by this invention is to have the problem that rolls the blind area when overcoming in the prior art construction of bridge attachment strap and the steady basic unit of water junction, and the job practices of a kind of improved bridge attachment strap and the steady basic unit of water junction is provided.
For solving above technical problem, the present invention takes following technical scheme:
The job practices of a kind of bridge attachment strap and the steady basic unit of water junction comprises the steps: at first, and the laying steady basic unit of water also rolls; Then the corresponding tooth pick division of toothed area that forms with bridge attachment strap one side is dug in an end of the steady basic unit of water; At last, build the bridge attachment strap, make the profile of tooth end of bridge attachment strap and the tooth pick division corresponding matching of the steady basic unit of water.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
The job practices of bridge attachment strap of the present invention and the steady basic unit of water junction is owing to having carried out the laying of the steady basic unit of water earlier and having rolled and dig the tooth pick division again, therefore can guarantee that the degree of compaction of toothed area meets design requirement, the steady basic unit of bridge attachment strap and water is fully linked, also can make toothed area have better planeness simultaneously.
Description of drawings
The present invention will be further described in detail below in conjunction with accompanying drawing and concrete embodiment:
Fig. 1 is the structural representation of bridge attachment strap and the steady basic unit of water junction in the prior art;
Fig. 2 is the enforcement schematic diagram of job practices of the present invention;
Wherein: 1,1 ', bridge attachment strap; 2,2 ', the steady basic unit of water; 20, tooth pick division; 3 ', toothed area.
The specific embodiment
The present invention will be further described in detail below in conjunction with specific embodiment, but be not limited to these embodiment.
Embodiment
As illustrated in fig. 1 and 2, carry out as follows according to the bridge attachment strap of present embodiment and the job practices of the steady basic unit of water junction:
At first, lay the steady basic unit 2 of water and also roll, make the width of the steady basic unit 2 of water satisfy construction requirement, and an end of the steady basic unit 2 of water stretches into about 50 ~ 60 centimetres of bridge attachment strap section, so that dig; Then, the end of stretching into bridge attachment strap section of the steady basic unit 2 of water is dug and toothed area 3 ' the corresponding tooth pick division 20 of formation and bridge attachment strap 1 one sides; At last, build bridge attachment strap 1, make the profile of tooth end of bridge attachment strap 1 and tooth pick division 20 corresponding matching of the steady basic unit 2 of water.
The present invention has guaranteed the degree of compaction and the planeness of steady basic unit of water and bridge attachment strap junction, can effectively stop the steady basic unit of water bottom soil or/and water etc. ooze out from this junction, the attachment strap that prevents place, this junction sinks and because of destroying too early etc. on the loosening road surface that causes of basic unit, thereby the road construction quality can be met design requirement, and guarantee the comfortableness and the safety of driving a vehicle.
More than the present invention has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences of doing according to spiritual essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention
