Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but implementation of the present utility model
Mode is not limited only to this.
As shown in figure 1, a kind of buried plastic tube passes through the waterproof construction of exterior wall, including the exterior wall 1 perpendicular to ground, exterior wall
The water string 2 for installing plastic tube 5 is equipped with 1.
In order to improve waterproof effect, water string 2 is embedded on the outer wall of exterior wall 1 and is circumferentially provided with seal ring 8 along it.Sealing
Ring 8 has blocked the penetrating passage between exterior wall 1 and water string 2, makes effectively block within the specific limits around water string 2
The seepage flow of water.Water string 2 can use rigid waterproof sleeve or soft waterproof casing, and 5 place through walls of plastic tube is not subject to pipe
When road is vibrated with dilatation, using rigid waterproof sleeve；Plastic tube 5 receives vibration through wall part or has tight waterproof will
Ask, using soft waterproof casing, so as to meet different buildings waterproof requirements.
In order to further improve waterproof effect, the side of exterior wall 1 is provided with retaining wall 3 in parallel, retaining wall 3 and exterior wall
Cavity 4 is formed between 1.Its axial direction of the interior edge of water string 2 is equipped with plastic tube 5, and the inwall of water string 2 and the outer wall of plastic tube 5 are tight
Closely connected conjunction.Plastic tube 5 sequentially passes through exterior wall 1, cavity 4 and retaining wall 3, is filled with cavity 4 anti-with caking property
Water packing layer 6, water tight packing layer 6 can use pitch.Plastic tube 5 can use PE to manage, and there is PE pipes excellent resistance to stress to open
Fragility, chemical resistance, resistance to ag(e)ing, so as to improve the service life of waterproof construction, reduce maintenance cost.
Pitch fills up gap of the plastic tube 5 at retaining wall 3 and exterior wall 1, avoids water from entering inspection shaft at gap
It is interior；Because pitch has caking property, asphalt adhesive in the outer wall of plastic tube 5 and retaining wall 3 side wall relative with exterior wall 1,
Sealing is formed, when plastic tube 5 expands with heat and contract with cold, pitch is not readily separated with plastic tube 5, retaining wall 3 and exterior wall 1, so as to keep away
Exempt to produce gap, further improve waterproof effect, reduce maintenance cost.

Plane.Exterior wall 1 and retaining wall 3 play certain supporting role to plastic tube 5, and the direction of support force is consistent, further improve
Waterproof effect.
As shown in Fig. 2 in order to avoid pitch separates with plastic tube 5, retaining wall 3 and exterior wall 1, plastic tube 5 is located in cavity 4
Outer wall on be provided with multiple raised 7, a side wall of retaining wall 3 and exterior wall 1 towards cavity 4 is provided with multiple raised 7.Plastic tube
Projection 7 in 5 outer walls, retaining wall 3 side wall relative with exterior wall 1, increases its roughness with Asphalt Contactor face, so as to increase
The adhesive force of big pitch, avoids producing gap between pitch and plastic tube 5, retaining wall 3 and exterior wall 1, improves waterproof effect.Plastics
The outer wall that pipe 5 is located in cavity 4 can use frosting, and the side wall relative with exterior wall 1 of retaining wall 3 can also be frosting.
Working principle and beneficial effect of the present utility model is as follows：
Pitch fills up gap of the plastic tube 5 at retaining wall 3 and exterior wall 1, avoids water from entering inspection shaft at gap
It is interior；Exterior wall 1 and retaining wall 3 play certain supporting role to plastic tube 5, reduce plastic tube 5 and are produced because unbalance stress deforms
Gap, further improve waterproof effect.
Because pitch has caking property, asphalt adhesive is in the outer wall of plastic tube 5 and retaining wall 3 side relative with exterior wall 1
On wall, sealing is formed.Projection 7 in the outer wall of plastic tube 5, retaining wall 3 side wall relative with exterior wall 1, increases itself and pitch
The roughness of contact surface, so as to increase the adhesive force of pitch.When plastic tube 5 expands with heat and contract with cold, pitch and plastic tube 5, gear
Cob wall 3 and exterior wall 1 are not readily separated, and avoid producing gap between pitch and plastic tube 5, retaining wall 3 and exterior wall 1, improve waterproof
Effect, reduce maintenance cost.
