Abstract
The invention discloses a protective cover for tunnel arc arch bar planting and wall protection construction, relates to the technical field of tunnel construction, and provides a protective cover for tunnel arc arch bar planting and wall protection construction, which can prevent stone slag and slurry from falling in the bar planting drilling process. The protective cover for tunnel arch bar planting and wall protection construction comprises a protective cover bottom plate and a plurality of protective cover vertical plates connected with the protective cover bottom plate; each protective cover vertical plate is arranged at intervals, and a dirt groove is formed between every two adjacent protective cover vertical plates; the protective cover bottom plate is provided with a cross-shaped notch and a fixing hole, and the edge of the protective cover bottom plate is provided with a connecting hole. The invention is fixed on the tunnel arch, covers the tunnel arch, and the stone slag and the slurry fall into the dirt groove and are discharged along the dirt groove, so the invention can avoid the stone slag and the slurry from falling, thereby not only improving the construction efficiency, but also ensuring the safety of constructors.
Description
Technical field
The present invention relates to technical field of tunnel construction, particularly relate to a kind of protective cover for tunnel arch bar planting and panelling construction.
Background technology
For the bar planting construction before tunnel arch retaining wall, first will hole to bar planting hole, what generally adopt is water drilling.Execute in drill-through journey, necessarily have rock ballast and come off from arch wall, also have mud simultaneously and overflow from boring.Rock ballast and mud both can affect constructor's operation, the safety of entail dangers to constructor again, but current not good mode solves this problem.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of protective cover for tunnel arch bar planting and panelling construction that rock ballast and mud in bar planting boring procedure can be avoided to drop.
In order to solve the problem, the technical scheme adopted is: some protective cover risers that the protective cover for tunnel arch bar planting and panelling construction comprises protective cover base plate and is connected with protective cover base plate; Each protective cover riser interval is arranged, and is dirt groove between adjacent protective cover riser; Protective cover base plate is provided with cross type cut and fixing hole, protective cover bottom edge is provided with connecting hole.
Further: protective cover base plate and protective cover riser are made by rubber and the two makes one.
The invention has the beneficial effects as follows: the present invention is fixed in tunnel arch, the present invention covers tunnel arch, rock ballast and mud are fallen into dirt groove and are discharged along dirt groove, and the present invention can avoid rock ballast and mud to drop, and has both improved the safety that efficiency of construction in turn ensure that constructor.
Accompanying drawing explanation
Fig. 1 is the front view of the protective cover for tunnel arch bar planting and panelling construction;
Fig. 2 is the lateral view of the protective cover for tunnel arch bar planting and panelling construction;
Be labeled as in figure: connecting hole 1, protective cover riser 2, cross type cut 3, fixing hole 4, protective cover base plate 5, dirt groove 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As depicted in figs. 1 and 2, for some protective cover risers 2 that the protective cover of tunnel arch bar planting and panelling construction comprises protective cover base plate 5 and is connected with protective cover base plate 5; Each protective cover riser 2 interval is arranged, and is dirt groove 6 between adjacent protective cover riser 2; Protective cover base plate 5 is provided with cross type cut 3 and fixing hole 4, protective cover base plate 5 edge is provided with connecting hole 1.
Utilize the present invention to carry out tunnel arch bar planting and panelling construction process as follows: A, in tunnel arch, beat hole for the expansion bolt, expansion bolt is passed fixing hole 4 and inserts hole for the expansion bolt, this protective cover is fixed in tunnel arch by expansion bolt, when fixing this protective cover, pressure should be avoided to collapse protective cover riser 2; B, repetition step A, fixing multiple protective cover is until protective cover covers tunnel arch completely, and adjacent protective cover is connected by connecting hole 1; Reinforcing shored by C, seal closure; D, use short drill pipe rig, adopt water drilling through cross type cut 3 and bore bar planting hole in tunnel arch; E, bar planting is installed and is in the milk in brill bar planting hole; F, dismounting protective cover; G, extension steel fabric sheet; H, sprayed mortar retaining wall.
Bore in the process of bar planting hole, the present invention covers tunnel arch, and rock ballast and mud are fallen into dirt groove 6 and discharged along dirt groove 6, and therefore the present invention can avoid rock ballast and mud to drop, and has both improved the safety that efficiency of construction in turn ensure that constructor.
Bore in the process of bar planting hole, protective cover will be fitted with tunnel arch, and therefore protective cover should be flexible, and the present invention recommends protective cover base plate 5 and protective cover riser 2 to make by rubber and the two makes one.
The effect of cross type cut 3 facilitates drill bit to pass protective cover; And when drill bit is through protective cover, the protective cover base plate 5 near cross type cut 3 is fitted with drill bit, makes substantially to seal between protective cover base plate 5 and drill bit, rock ballast and mud can be avoided to drop out between drill bit and protective cover base plate 5.
Claims (2)
1., for the protective cover of tunnel arch bar planting and panelling construction, it is characterized in that: the some protective cover risers (2) comprising protective cover base plate (5) and be connected with protective cover base plate (5); Each protective cover riser (2) interval is arranged, and is dirt groove (6) between adjacent protective cover riser (2); Protective cover base plate (5) is provided with cross type cut (3) and fixing hole (4), protective cover base plate (5) edge is provided with connecting hole (1).
