Abstract
The utility model discloses a tunnel waterproof board fixing and lap-jointing structure, and relates to the technical field of underground engineering construction. The fixing and lap-jointing structure comprises an initial concrete support (1), a waterproof board (2), a pre-embedded steel sheet piece (3) and a three-way groove rubber connecting piece (4), wherein one end of the pre-embedded steel sheet piece (3) is pre-embedded in the initial concrete support (1), while the other end of the pre-embedded steel sheet piece (3) is connected into the three-way groove rubber connecting piece (4), and one end of the waterproof board is also connected into the three-way groove rubber connecting piece (4). The fixing and lap-jointing structure achieves a novel connection way which is simple in construction and materials.
Description
Technical field:
The utility model relates to the Construction Technique of Underground Works field, is specifically related to a kind of anchor bar of waterproof plate in tunnels and fixes and bridging arrangement.
Background technology:
In the underground engineering construction of railway, highway, subway tunnel, the most frequently used method of tunnel lining is first on the tunnel metope, to spray the sprayed mortar of 5-20 centimetre of one deck as the preliminary bracing layer, then lay the geotextiles cushion coat, splash guard is installed again, and rear mold is built the concrete secondary liner of 30-50 centimetre.
Waterproofing course is comprised of geotextiles and splash guard usually, and effect is the path between blocking groundwater and secondary lining.Usually the job practices of splash guard is for first saying that the nail nail is in supporting in the early stage, then splash guard is fastened on nail, ailhead easily punctures splash guard like this, destroy the globality of splash guard, affect result of use, and construction is trouble comparatively, inefficiency, be improved to afterwards first floor splash guard nail propped up on mask in the early stage, then with second layer splash guard, covered fixed position, be welded on first floor, in this job practices, rosin joint easily appears in welding position, and the phenomenons such as few weldering, easily cause and leak, and construction sequence is more, quality is wayward.The overlap joint of splash guard typically uses welding, rosin joint easily occurs, the situation of few weldering or destruction splash guard, and construction is comparatively complicated, and efficiency is very low.
The utility model content:
The purpose of this utility model is to provide a kind of anchor bar of waterproof plate in tunnels and fixes and bridging arrangement, and it utilizes steel disc built-in fitting and the combination of three-dimensional groove rubber connector be embedded in the concrete preliminary bracing, and fixedly splash guard and preliminary bracing, can overlap splash guard again.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises concrete preliminary bracing 1, splash guard 2, steel disc built-in fitting 3 and three-dimensional groove rubber connector 4, one end of steel disc built-in fitting 3 is embedded in solidifying native preliminary bracing 1, the other end of steel disc built-in fitting 3 is connected in three-dimensional groove rubber connector 4, and an end of splash guard 2 is connected in three-dimensional groove rubber connector 4.
Described steel disc built-in fitting 3 is for bar shaped steel disc structure and be provided with pawl shape structure, can increase like this its contact area, has well improved the connection of two parts.
Described splash guard 2 for gapless is connected, can better be realized the effect of waterproof with three-dimensional groove rubber connector 4 like this.
The utility model operating principle: steel disc built-in fitting 3 was first fixed along the tunnel cross section hoop before sprayed mortar preliminary bracing 1, and reserve concrete preliminary bracing face 1-2 centimetre, to inject three-dimensional groove rubber connector 4 after steel disc built-in fitting 3 daubs that reserve, after glue is dry, respectively the splash guard on both sides 2 edge daubs are inserted to three-dimensional groove rubber connector 4.
The utlity model has following beneficial effect: improved the method for attachment of splash guard and tunnel metope, do not destroy the globality of splash guard fully, very high bonding strength is arranged, job practices is simple, step is few, efficiency of construction improves 2-3 doubly, and waterproofing course especially full-packaging waterproof layer is had very important significance.Improved the bridging method between splash guard simultaneously, avoided the overlap joint crack fully, good according to the waterproofing course planeness after this structure construction, tight with the laminating of tunnel metope, very high globality and planarization are arranged, facilitate the construction of secondary lining, construction technology is simple, overlap joint speed is very fast, has very high production efficiency and economic benefit.Waterproofing course with this structure overlap joint has very high scalability, can prevent from that the splash guard caused because of the secondary lining concrete deformation from destroying to cause waterproofing course to lose efficacy.
The accompanying drawing explanation:
Fig. 1 is the cross-sectional view strength of the utility model node;
Fig. 2 is the plan view of the utility model node.
The specific embodiment:
Referring to Fig. 1, Fig. 2, this specific embodiment is by the following technical solutions: it comprises concrete preliminary bracing 1, splash guard 2, steel disc built-in fitting 3 and three-dimensional groove rubber connector 4, one end of steel disc built-in fitting 3 is embedded in solidifying native preliminary bracing 1, the other end of steel disc built-in fitting 3 is connected in three-dimensional groove rubber connector 4, and an end of splash guard 2 is connected in three-dimensional groove rubber connector 4.
Described steel disc built-in fitting 3 is for bar shaped steel disc structure and be provided with pawl shape structure, can increase like this its contact area, has well improved the connection of two parts.
Described splash guard 2 with three-dimensional groove rubber connector 4 for gapless is connected, the effect that realizes waterproof that can follow like this.
This specific embodiment operating principle: steel disc built-in fitting 3 was first fixed along the tunnel cross section hoop before sprayed mortar preliminary bracing 1, and reserve concrete preliminary bracing face 1-2 centimetre, to inject three-dimensional groove rubber connector 4 after steel disc built-in fitting 3 daubs that reserve, after glue is dry, respectively the splash guard on both sides 2 edge daubs are inserted to three-dimensional groove rubber connector 4.
This specific embodiment has following beneficial effect: it is a kind of simple structure, material is simple, the simple Novel connection type of constructing, it has improved the method for attachment of splash guard and tunnel metope, does not destroy the globality of splash guard fully, and very high bonding strength is arranged, job practices is simple, step is few, and efficiency of construction improves 2-3 doubly, and waterproofing course especially full-packaging waterproof layer is had very important significance.Improved the bridging method between splash guard simultaneously, avoided the overlap joint crack fully, good according to the waterproofing course planeness after this structure construction, tight with the laminating of tunnel metope, very high globality and planarization are arranged, facilitate the construction of secondary lining, construction technology is simple, overlap joint speed is very fast, has very high production efficiency and economic benefit.Waterproofing course with this structure overlap joint has very high scalability, can prevent from that the splash guard caused because of the secondary lining concrete deformation from destroying to cause waterproofing course to lose efficacy.
