Description
Technical field
The utility model belongs to building, water conservancy construction field, relates to the antiseep process between PVC pipeline, pipe spreading shutoff leakage preventing structure in the pre-buried pvc pipe cover of especially a kind of concrete wall.
Background technology
Pipe grafting technique in the pre-buried pvc pipe cover of Reinforced Concrete Retaining Walls, is widely used in building, hydraulic engineering.Reinforced concrete wall behind ponding is discharged often through wall pre-embedded water pipe, and water pipe need extend to the outer 2-5 rice of body of wall, by Waterflow-guiding to assigned address.But when practice of construction, affecting by template restriction or extension tube front-end architecture can not one-shot forming, need first pre-buried pvc pipe between reinforced concrete wall, by pipeline spreading after wall construction is complete, because reinforced concrete wall requires restriction by antiseepage requirement and pipeline gradient, adopt the direct spreading of inner connecting tube cannot reach antiseepage requirement, therefore to need to adopt in cover close measure after pipe spreading, workable, anti-seepage effect is very good.
Retrieved by patent document, not yet find the patent document identical with the utility model.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art part, pipe spreading shutoff leakage preventing structure in the pre-buried pvc pipe cover of a kind of concrete wall is provided, this structure seeps water can obtain effective block wall after pvc pipe spreading after, ensures that occluding member is the same with concrete guard wall anti-seepage effect.
The utility model is that technical solution problem adopts following technical scheme:
Pipe spreading shutoff leakage preventing structure in the pre-buried pvc pipe cover of a kind of concrete wall, pre-buried pvc pipe is inclined and mounted in impervious concrete barricade, in pre-buried pvc pipe, coaxial installation in PVC is managed, asbestos cement sealant is adopted to seal between pipe and pre-buried pvc pipe in this PVC, it is characterized in that: be coaxially installed with in the asbestos cement sealant in PVC between pipe and pre-buried pvc pipe and combine waterproof packed layer, the structure of this combination waterproof packed layer is: coaxial installation one hydro-expansive rubber sealing collar on pipe in the PVC in asbestos cement sealant, be symmetrically installed with spunyarn in asbestos cement sealant in the PVC of these hydro-expansive rubber sealing collar both sides between pipe and pre-buried pvc pipe and soak polyurethane water-swellable water stop gel ring.
And, clog by polyurethane water-swellable water-stop glue between the hydro-expansive rubber sealing collar between spunyarn leaching polyurethane water-swellable water stop gel ring and pre-buried pvc pipe inwall.
And the difference of the external diameter of pipe is not less than 5cm in the external diameter of described pre-buried pvc pipe and PVC.
Advantage of the present utility model and good effect are:
1, the utility model adopts the method for pipe spreading in cover, and decrease the fixation problem that front pvc pipe sponson built by steel concrete, technological operation is easy, and constructor is easy to grasp, safe and reliable, and pvc pipe spreading synchronously can carry out with rolling earth behind retaining wall.
2, the utility model carries out after reinforced concrete wall construction, eliminate built-in pipe in concrete construction and pass template spillage problem, avoid the generation of hidden danger of quality, within can being widely used in DN500, impervious concrete pipe built-in pvc pipe overlaps interior pipe spreading, workable, anti-seepage effect is very good.
Accompanying drawing explanation
Fig. 1 is cross section schematic diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
Detailed description of the invention
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, it should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
Pipe spreading shutoff leakage preventing structure in the pre-buried pvc pipe cover of a kind of concrete wall, pre-buried pvc pipe 4 is downward-sloping to be arranged in impervious concrete barricade 1, in pre-buried pvc pipe, pipe 7 in coaxial installation PVC, adopts asbestos cement sealant 6 to seal between pipe and pre-buried pvc pipe in this PVC.
Innovative point of the present utility model is:
Be coaxially installed with in asbestos cement sealant in PVC between pipe and pre-buried pvc pipe and combine waterproof packed layer, its structure is: coaxial installation one hydro-expansive rubber sealing collar 3 on pipe in the PVC in asbestos cement sealant, is symmetrically installed with spunyarn and soaks polyurethane water-swellable water stop gel ring 5 between this hydro-expansive rubber sealing collar both sides and asbestos cement sealant.
In order to improve barrier performance further, polyurethane water-swellable water-stop glue 2 is clogged between pipe in hydro-expansive rubber sealing collar between spunyarn leaching polyurethane water-swellable water stop gel ring and PVC, this structure can ensure the bonding of pvc pipe and water expandable waterstop, can prevent the capillary water seepage flow between packed layer and pvc pipe wall.
In the present embodiment, in the external diameter of described pre-buried pvc pipe and PVC, the difference of the external diameter of pipe is not less than 5cm.
In the present embodiment, the thickness of described water-swelling rubber water bar is not less than 2.0cm.
In the present embodiment, described spunyarn leaching polyurethane water-swellable water stop gel ring take PN-220 as material.
In the present embodiment, be water in mass ratio in described asbestos cement sealant: asbestos: cement=1: 3: 7, asbestos cement sealant is used for outer sealing, also claim asbestos expansive cement, these asbestos are 4 grades or 5 grades of asbestos wools, and cement adopts the portland cement being not less than No. 425, asbestos cement packing seal layer should be finished in 1 hour, otherwise exceeding jelling time can affect sealing effect, the maintenance of asbestos cement sealant need more than 24 hours; Asbestos cement has higher-strength and good shock resistance, watertightness and bonding force good;
In the present embodiment, described water-swellable sealing collar rubber strip used is by the quality of rubber materials with water-swellable characteristic, meets water and start expansion and make waterproof, stagnant water effect better under expanded rubber effect.
When in PVC, pre-buried pvc pipe put into by pipe, the center of interior pipe and concrete embedded pipe to be ensured on the same axis as far as possible, before the filling carrying out asbestos cement sealant, need to carry out the process of brush polyurethane water-swellable water-stop glue to tube wall, asbestos cement sealant needs filling closely knit in interlayer, after completing filling, use water-repellent paint brushing, complete the work of pipeline spreading.
