DETAILED DESCRIPTION
[0017] As Figure 1 shown is a kind of crossing current box-type drainage ditch's driving structure of construction space being effectively saved, which can protect drainage facilities.The driving structure includes current box-type drainage ditch 1, the top of current box-type drainage ditch is opened and is closed by detachable concrete cover plate, the driving structure further includes support block 2, buffer transition filling body 3 and beam-type concrete pavement 4, support block 2 is arranged on the excavated foundation of both sides of current box-type drainage ditch in width direction respectively, beam-type concrete pavement 4 is crossed in the upper of current box-type drainage ditch 1 by support block 2, buffer transition filling body 3 is connected between beam-type concrete pavement 4 and the concrete cover plate of the top of current box-type drainage ditch.The technical scheme provided in the application is based on the existing current box-type drainage ditch, combined with the structural characteristics that the top of current box-type drainage ditch is opened and is closed by detachable concrete cover plate, by increasing the setting support block, buffer transition filling body and beam-type concrete pavement, the driving structure of the application is formed, then support block is set to the excavated foundation of both sides of current box-type drainage ditch in width direction, and makes beam-type concrete pavement cross in the upper of current box-type drainage ditch by support block, then makes buffer transition filling body connect between beam-type concrete pavement and the concrete cover plate of the top of current box-type drainage ditch.In this way, when the traffic tool runs, it does not run directly on the concrete cover plate of current box-type drainage ditch, but directly runs on beam-type concrete pavement, and load is transmitted to the foundation of both sides of current box-type drainage ditch by support block, which can protect drainage facilities and effectively save construction space, without the need to change the existing drainage facilities, realize the original drainage structure to continue to run, and can move the original municipal road on the drainage facilities without damaging the original drainage structure, save the space requirement of construction.
[0018] Combined with the actual situation of production site, in order to facilitate construction, the beam-type concrete pavement 4 and the support block 2 of the application are integrally formed, and at least the beam-type concrete pavement 4 is a reinforced concrete pavement.Meanwhile, in order to improve the strength and support effect, the projection of the integrally formed beam-type concrete pavement 4 and the support block 2 in the axial vertical plane is in the shape of an eight-character arch bridge.The inclination of the two groups of support block inclined surfaces constituting the eight-character arch bridge is preferably 30-45°, and the thickness of the buffer transition filling body 3 composed of foamed plastic is not less than 100mm.
[0019] Further, in order to avoid the foundation settlement of the driving structure in operation, the excavation foundation below the support block is filled with a rough flat concrete pouring layer 5, and the thickness of the rough flat concrete pouring layer 5 is not less than 50 mm. At this time, a compacted hardened ground layer 6 is further arranged below the rough flat concrete pouring layer 5, and the thickness of the compacted hardened ground layer 6 is not less than 150 mm. Meanwhile, the compacted hardened ground layer 6 is arranged on the excavation compacted bottom foundation layer 7. More specifically, the thickness of the beam type concrete pavement 4 is not less than 300 mm. The thickness of the support block 2 is not less than 900 mm. The depth of the excavation foundation is not less than one third of the depth of the existing box type drainage ditch 1.
[0020] In summary, the technical scheme of the present application is to transmit the driving load to the gap of the structure which is at least 100 mm away from the top surface of the drainage ditch, so as to ensure that the stress influence line of the two ends of the foundation is not conducted to the existing drainage facility, thereby protecting the drainage facility and ensuring its drainage function while ensuring the passage of automobile load. It is suitable for traffic diversion in narrow space and short construction time. From the structure, the driving structure of the present application is similar to a small bridge, which uses the principle of bridge structure to suspend the protected drainage facility, uses the foundation to conduct stress, and then realizes the function of protecting the existing drainage structure and realizing the passage of automobile. The present application can not only use reinforced concrete material as the foundation and the panel, but also use I-beam as the foundation, and use the steel plate welded with the I-beam as the panel to cross the protected facility.
[0021] The technical scheme of the present application will be further described below through specific examples:
[0022] Example 1
[0023] In order to divert traffic when there is no additional construction space for drainage ditch relocation at the construction site and in order to quickly realize the demand of traffic diversion, the technical scheme of the present application can realize quick traffic diversion, and the driving lane can be diverted to the drainage facility which cannot bear the driving load originally, and the drainage facility after the pavement structure can continue to be used.
[0024] The specific technical scheme is as follows:
[0025] 1) Excavate on both sides of the existing ditch to the designed depth and the required width of the foundation, fully compact the soil of the bottom foundation layer to achieve the designed compaction degree;
[0026] 2) Then, lay 150 mm thick graded gravel and fully compact it to form a certain strength base layer;
[0027] 3) Pour 50 mm of rough flat concrete to form a relatively flat base layer by using concrete to prevent uneven settlement of the foundation of the driving structure in the later stage;
[0028] 4) Then the present situation box type drainage ditch top pavement is laid a layer of 100mm thick foam plastic, to avoid load transmission to the box type drainage ditch;
[0029] 5) According to the design drawing, the steel bars are bound;
[0030] 6) The concrete is poured in layers, and is maintained in time, and when the strength is formed, the structure can be used as a carriageway to bear the automobile load, the automobile load is transmitted to the foundations on both sides through the structure, the drainage ditch is protected, and the traffic is successfully kept open.
[0031] The technical scheme of the application not only protects the original drainage facilities of the municipal pavement, guarantees that the original drainage facilities can continue to be used, but also can move the road traffic to the road drainage facilities, and can also transfer the driving load to the foundation of the driving structure, so that the original drainage facilities are not stressed. On the other hand, space is saved for traffic diversion, especially suitable for places where the construction space is particularly narrow, and new drainage facilities do not need to be newly built, not only saving time, but also saving money, having considerable economic benefits.
