Abstract
The invention discloses a soil slag falling prevention device, and belongs to the field of municipal construction tools. The soil slag falling prevention device comprises a falling groove (3). A groove edge (6) is arranged at the top end of the falling groove (3). The outer diameter of the groove edge (6) is smaller than the inner diameter of an inspection well. A sealing ring (2) is arranged on the outer side of the groove edge (6). A pair of handles (4) is fixedly arranged on the top face of the groove edge (6). At least three bolt holes (1) are further fixedly arranged on the top face of the groove edge (6). Screws (5) are in threaded connection with bolt holes (1) and are horizontally arranged. The structure is simple, mounting and dismounting are convenient, and the situation that soil slag and structural mixtures fall into the inspection well in the wellhead hidden backfill or excavation process is ingeniously avoided; and the soil slag and the like fall into the falling groove (3), and cleaning is facilitated.
Description
Technical field
The present invention relates to municipal construction field of tool, particularly to one kind anti-soil slag dropping device.
Background technology
In Municipal Road Engineering construction, road range check well is numerous, is smoothed out for accessible the paving of guarantee, improves service efficiency and the job area of decking and rolling machinery, improves the construction quality of each structure sheaf of road（Reduce mixture segregation, improve flatness）, we need hidden for the covering of manhole shaft position under road foundation, dig opening after the construction of road structure layer finishes, expose shaft location, build and build pit shaft, well lid is installed, intermediate demand is repeatedly hidden and excavates repeatedly, in backfill and digging process, originally concrete cover plate is used to cover hidden, more than 20 centimetres above ground level, do not meet the design concept of the accessible construction that paves, form the new barrier that paves, the reason such as mechanical collision during subsequent job, position offsets, well head covers imprecision, it is indoor that native slag easily enters well, easily cause flowing line blocking, the accidents such as special pipelines destruction.Because the well interior space is narrow and small, later stage cleaning is extremely difficult, and workload is very big.
Content of the invention
In order to make up above deficiency, the invention provides structure is simple, native slag etc. can be avoided to fall into the anti-soil slag dropping device in inspection shaft.
The technical scheme is that：
A kind of anti-soil slag dropping device it is characterised in that：Including falling groove 3, described groove 3 top of falling is provided with groove along 6, and the external diameter along 6 for the described groove is less than the internal diameter of inspection shaft；Described groove is provided with sealing ring 2 along outside 6；Described groove is fixedly installed a pair of handle 4 along along 6 top surfaces, and described groove is also fixedly installed at least three bolts hole 1 along along 6 top surfaces；Screw rod 5 is threadeded with bolt hole 1, and screw rod 5 is horizontally disposed with.
Preferably, described groove is fixedly installed three bolts hole 1 along along 6 top surfaces.
Further, three described bolts hole 1 are uniformly distributed in described groove along along 6 top surface.
Preferably, the external diameter at least 20mm less than the internal diameter of inspection shaft along 6 for the described groove.Lateral gap sealing ring 2 is adjusted.
Preferably, described sealing ring 2 is rubber seal.
In the hidden backfill of well head or digging process, fall in inspection shaft to prevent and treat native slag and road structure compound, install the anti-soil slag dropping device of the present invention in well head additional.During construction, add a circle spacing collar close to the well inwall of well head, and several fixing holes are added on the borehole wall；Hand-held handle, will fall groove 3 and put at well head, after putting down, groove is just contacted with spacing collar along 6, rotary screw 5, and the end of screw rod 5 is more and more nearer away from the borehole wall, finally, screw rod 5 is threaded into the fixing in the hole on the borehole wall, and the installation realizing the present invention anti-soil slag dropping device is fixed.Because groove is provided with sealing ring 2 along outside 6, it is further ensured that and avoids native slag and road structure compound to fall into inspection shaft.
Beneficial effects of the present invention are：
Present configuration is simple, installs and convenient disassembly, cleverly avoids in the hidden backfill of well head or digging process, native slag and structure compound fall in inspection shaft；Native slag etc. falls into and falls in groove 3, and native slag falls in falling in groove 3, is convenient to clean.
Brief description
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing of required use in embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, without having to pay creative labor, other accompanying drawings can also be obtained according to these accompanying drawings.

Specific embodiment
Embodiment 1
As shown in figure 1, the anti-soil slag dropping device of the present invention falls groove 3, there is no particular/special requirement to the depth falling groove 3, typically its depth is between 30mm-300mm.Fall groove 3 top and be provided with groove along 6, the external diameter at least 20mm less than the internal diameter of inspection shaft along 6 for the groove.Groove is provided with rubber seal 2 along outside 6.
Groove is fixedly installed a pair of handle 4 along along 6 top surfaces, is easy to move；Groove is also fixedly installed three bolts hole 1 along along 6 top surfaces, and three bolts hole 1 are uniformly distributed in described groove along along 6 top surface.Screw rod 5 is threadeded with bolt hole 1, and screw rod 5 is horizontally disposed with.
In the hidden backfill of well head or digging process, fall in inspection shaft to prevent and treat native slag and road structure compound, install the anti-soil slag dropping device of the present invention in well head additional.
During construction, add a circle spacing collar close to the well inwall of well head, and several fixing holes are added on the borehole wall；Hand-held handle, will fall groove 3 and put at well head, after putting down, groove is just contacted with spacing collar along 6, rotary screw 5, and the end of screw rod 5 is more and more nearer away from the borehole wall, finally, screw rod 5 is threaded into the fixing in the hole on the borehole wall, and the installation realizing the present invention anti-soil slag dropping device is fixed.Because groove is provided with sealing ring 2 along outside 6, it is further ensured that and avoids native slag and road structure compound to fall into inspection shaft.
Using the present invention, native slag etc. falls into and falls in groove 3, thus avoiding in the hidden backfill of well head or digging process, native slag and structure compound fall in inspection shaft.
