Description
Technical Field
The utility model relates to a piping lane waterproof construction, more specifically the theory relates to a construction joint waterproof construction.
Background
The city underground pipe gallery can integrate engineering pipelines such as electric power, communication, fuel gas and the like. As the leakage and water leakage can cause fire disasters of the power pipeline, even gas pipeline explosion disasters and the like in serious conditions, and the urban operation safety is influenced.
The construction joint refers to a joint formed between the concrete poured before and after the concrete is poured in sections due to design requirements or construction requirements in the concrete pouring process. The construction joint is not a real existing joint, and only because the initial setting time of the first poured concrete is longer than the initial setting time, a joint surface exists between the first poured concrete and the later poured concrete, and the joint surface is called as the construction joint. Avoiding this department's seepage during construction is one of the key step of preventing the piping lane from leaking, and although there are a lot of leak protection treatment to the construction joint at present, its leak protection effect is all unsatisfactory, and the condition of seepage into water takes place occasionally, awaits urgent need to improve.
SUMMERY OF THE UTILITY MODEL
Not enough to exist among the prior art, the utility model aims to provide a movement joint waterproof construction has solved the easy seepage problem of construction joint among the prior art.
In order to achieve the above object, one of the technical solutions of the present invention is as follows:
the waterproof structure of the longitudinal horizontal construction joint of the inner wall and the outer wall of the pipe gallery comprises a water stop belt which is perpendicular to the construction joint surface, and a cement mortar leveling layer, a waterproof coiled material layer, a protective layer and a protective drainage plate which are sequentially arranged on the outer wall of the pipe gallery; waterproof paint is coated on the joint surface of the construction joint and the leveling layer; the water stop is a steel plate water stop, and two sides of the water stop are fixed with concrete steel bars; the waterproofing membrane layer is unanimous with the whole waterproofing membrane of piping lane.
Compared with the prior art, the technical scheme has the following beneficial effects:
the steel plate water stop is fixed on the concrete reinforcing steel bar, so that the position deviation caused by displacement is not easy to occur during pouring; set up multilayer structure waterproof outside the piping lane to set up waterproof coiled material layer and the piping lane outer waterproof coiled material layer in unanimous position, conveniently lay in succession, can also stagger handing-over department and the construction joint on two waterproof coiled material layers, realize better water-proof effects.
Additional advantages, objects, and features of the above-described aspects will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the above-described aspects.
Drawings
Fig. 1 is a cross-sectional view of a pipe gallery construction joint.
Wherein, construction joint 1, waterstop 2, screed-coat 3, waterproof coil stock layer 4, protective layer 5, drain bar 6, enhancement layer 7.
Detailed Description
In order to make the technical means, creation features, achievement purposes and effects of the technical scheme clearer and easier to understand, the technical scheme is further described in the following combined with specific embodiments:
as shown in fig. 1, the utility model provides a vertical and horizontal construction joint waterproof structure for the inner and outer walls of a pipe gallery, which comprises a water stop 2 arranged perpendicular to the joint surface of a construction joint 1, and a cement mortar leveling layer 3, a waterproof coil material layer 4, a protective layer 5 and a protective drainage plate 6 which are arranged on the outer wall of the pipe gallery in sequence; waterproof paint is coated on the joint surface of the construction joint 1 and the leveling layer 3; the water stop 2 is a steel plate water stop 2, and two sides of the water stop 2 are fixed with concrete reinforcing steel bars; waterproofing membrane layer 4 sets up on same layer with the whole waterproofing membrane of piping lane.
According to the above technical scheme, the utility model discloses a technical thought does: the seam face of perpendicular to construction joint 1 sets up waterstop 2, and various protective layers 5 that the cooperation piping lane outer wall set up reach multiple waterproof effect. Waterproof coiled material layer 4 keeps unanimous with the holistic waterproof coiled material layer 4 of piping lane to do not set up the handing-over department on waterproof coiled material layer 4 near construction joint 1, guarantee the biggest waterproof ability. The drainage plate 6 is arranged outside the construction joint 1, so that the waterproof pressure part at the construction joint 1 is reduced to be dispersed to other positions, and multiple waterproof protection at the construction joint 1 is realized.
Preferably, 2 waterstops are located and bury underground in side wall central line department, 2 turn-ups of steel sheet waterstop are to the outer perk of piping lane. The one side outside towards the piping lane is the upstream face, and the lateral buckling of stagnant water board width direction's edge towards the upstream face can increase one-way waterproof ability.
Preferably, a waterproof reinforcing layer 7 is arranged between the waterproof roll material layer and the protective layer 5, and the width of the waterproof reinforcing layer 7 is larger than that of the drainage plate 6. The waterproof ability of further increasing construction joint 1 department on waterproof coiled material layer is strengthened in the setting, and waterproof enhancement layer 7 wide in drain bar 6's width simultaneously can reduce the waterproof pressure of 6 border positions of drain bar.
Preferably, the overlapping length of the two overlapped water stops 2 is more than 50mm, and the two sides are both welded. The length of the waterstop 2 is generally not consistent with the length required outside the pipe gallery, so that the overlapping condition can be involved, and the strength can be ensured by longer overlapping length and more comprehensive welding. Meanwhile, the lap joint position is far away from the corners of the pipe gallery and the positions of the male corner and the female corner. Because the corners are generally provided with other waterproof structures and the waterproof requirements are different, the overlapping is not suitable.
Preferably, in the concrete on both sides of the casting construction joint 1, the joint surface of the concrete cast first is roughened. During construction, concrete on two sides of the joint surface of the construction joint 1 is poured in different time periods, and the occlusion degree is increased through roughening treatment. The water stop 2 is fixed in a welding mode, and when the water stop 2 intersects with a concrete reinforcing steel bar, for example, when the water stop 2 penetrates through the stirrup, the stirrup can be cut off and then the water stop 2 is welded on two sides of the water stop respectively.
It is worth to be noted that when the construction joint 1 is arranged, the construction joint is arranged at a position where the structure is small in shearing force and convenient to construct; locations where the foundation is too wet should be avoided as much as possible. The half side of the water stop 2 is poured and fixed along with the first section of concrete. Leveling layer 3 adopts cement mortar, and waterproofing membrane adopts the polymer self-adhesive waterproofing membrane that can creep, and when covering planting soil, protective layer 5 is the filter layer and sets up root resistance type self-adhesive geotechnological cloth. And when no planting soil exists, a fine aggregate concrete protective layer 5 is arranged.
Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
