Description
Technical field
The present invention relates to municipal construction field of tool, particularly the anti-native slag dropping device of one.
Background technology
In Municipal Road Engineering construction, road range check well is numerous, for ensureing that accessible paving is carried out smoothly, improve service efficiency and the job area of decking and rolling machinery, the construction quality improving each deck of road (reduces mixture segregation, improve planeness), we need manhole shaft position to cover hidden under road foundation, dig opening after treating the construction of road structure layer, expose shaft location, build and build pit shaft, well lid is installed, intermediate demand repeatedly hidden and excavation repeatedly, backfill and digging process in, originally concrete cover plate covers hidden, more than 20 centimetres above ground level, do not meet the design concept of the accessible construction that paves, form the new obstruction that paves, the reason such as mechanical collision during subsequent job, position offsets, well head covers imprecision, soil slag very easily enters well indoor, flowing line is easily caused to block, the accidents such as special pipelines destruction.Because the well interior space is narrow and small, later stage cleaning is very difficult, and workload is very large.
Summary of the invention
In order to make up above deficiency, the invention provides structure simple, native slag etc. can be avoided to fall into anti-native slag dropping device in manhole.
Technical scheme of the present invention is:
A kind of anti-native slag dropping device, is characterized in that: comprise and fall groove 3, described in fall groove 3 top and be provided with groove along 6, the external diameter of described groove along 6 is less than the internal diameter of manhole; Described groove is provided with sealing ring 2 outside 6; Described groove is along 6 end faces being fixedly installed a pair handle 4, and described groove is also fixedly installed at least three bolts hole 1 along on 6 end faces; Screw rod 5 is threaded with bolt hole 1, and screw rod 5 is horizontally disposed with.
Preferably, described groove is along 6 end faces being fixedly installed three bolts hole 1.
Further, three described bolts hole 1 are homogeneous is distributed in described groove along on the end face of 6.
Preferably, external diameter than the internal diameter of the manhole little at least 20mm of described groove along 6.Lateral gap sealing ring 2 regulates.
Preferably, described sealing ring 2 is rubber seal.
In the hidden backfill of well head or digging process, in order to prevent and treat native slag and road structure compound falls in manhole, install anti-native slag dropping device of the present invention additional at well head.During construction, the well inwall close to well head adds a circle spacing collar, and on the borehole wall, add several fixing hole; Hand-held handle, will fall groove 3 and put into well head place, after putting down, groove just in time contacts with spacing collar along 6, rotary screw 5, and the end-to-end distance borehole wall of screw rod 5 is more and more nearer, finally, screw rod 5 is threaded in the fixing hole on the borehole wall, and the installation realizing the anti-native slag dropping device of the present invention is fixed.Because groove is provided with sealing ring 2 outside 6, ensure further to avoid native slag and road structure compound to fall into manhole.
Beneficial effect of the present invention is:
Structure of the present invention is simple, and install and convenient disassembly, avoid in the hidden backfill of well head or digging process cleverly, native slag and structure compound fall in manhole; Soil slag etc. falls into and falls in groove 3, and native slag falls in falling in groove 3, is convenient to cleaning.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the anti-native slag dropping device of the present invention;
1-bolt hole; 2-sealing ring; 3-falls groove; 4-handle; 5-screw rod; 6-groove edge.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, anti-native slag dropping device of the present invention falls groove 3, and do not have particular/special requirement to the degree of depth falling groove 3, generally its degree of depth is between 30mm-300mm.Fall groove 3 top and be provided with groove along 6, external diameter than the internal diameter of the manhole little at least 20mm of groove along 6.Groove is provided with rubber seal 2 outside 6.
Groove, along 6 end faces being fixedly installed a pair handle 4, is convenient to move; Along 6 end faces are also fixedly installed, three bolts hole, 1, three bolts hole 1 are homogeneous is distributed in described groove along on the end face of 6 to groove.Screw rod 5 is threaded with bolt hole 1, and screw rod 5 is horizontally disposed with.
In the hidden backfill of well head or digging process, in order to prevent and treat native slag and road structure compound falls in manhole, install anti-native slag dropping device of the present invention additional at well head.
During construction, the well inwall close to well head adds a circle spacing collar, and on the borehole wall, add several fixing hole; Hand-held handle, will fall groove 3 and put into well head place, after putting down, groove just in time contacts with spacing collar along 6, rotary screw 5, and the end-to-end distance borehole wall of screw rod 5 is more and more nearer, finally, screw rod 5 is threaded in the fixing hole on the borehole wall, and the installation realizing the anti-native slag dropping device of the present invention is fixed.Because groove is provided with sealing ring 2 outside 6, ensure further to avoid native slag and road structure compound to fall into manhole.
Use the present invention, native slag etc. fall into and fall in groove 3, thus avoid in the hidden backfill of well head or digging process, and native slag and structure compound fall in manhole.
