Description
Technical field
This utility model is related to a kind of water sealing structure for concrete for hydraulic structure movement joint.It is applied to Hydro-concrete Structures
Engineering water-stop technology field.
Background technology
Xoncrete structure, under temperature change, humidity change and the unequal effect of load assignment, often can deform, lead to
Structure crack even destroys.For this reason, often pre-setting build joint (movement joint 1), structure is disconnected, being deformed with commensurate structure is needed
Will.
To underwater concrete structure, for preventing outer water from leaking out to inside configuration along seam face, should arrange reliable at movement joint 1
Measures of preventing water.To water-retaining structures such as concrete dam, Factory Building, sluice, as shown in figure 1, movement joint sealing generally adopts twice sealing
Copper sheet 2, in the equal embedded concrete structure in the every side of copper seal 23, is spaced 50～100cm between twice copper seal 2.Should be only
Because of the dry-shrinkage deformed impact of concrete itself, along with sealing, nearby concrete is difficult to vibration compacting to water-bound, causes sealing copper
Combine not tight between piece and concrete, and leakage passage occurs and leads to water slop failure.
Content of the invention
The technical problems to be solved in the utility model is：A kind of water sealing structure for concrete for hydraulic structure movement joint is provided,
Pattern is simple, sealing is reliable, easy construction, to solve the problems, such as movement joint water slop failure.
This utility model be employed technical scheme comprise that：For the water sealing structure of concrete for hydraulic structure movement joint, described deformation
Seam is set in advance in from the xoncrete structure of upstream face to back side, because the presence of movement joint makes xoncrete structure be divided into a left side
The concrete block of right two parts and substage construction is it is characterised in that arrange twice copper seal, two sealing copper along the movement joint junction of the edges of two sheets of paper
Pre-embedment grouting pipe in movement joint between piece, pre- in the movement joint between the copper seal of nearly back side and back side concrete wall
Bury drain pipe.
The copper seal of nearly upstream face, apart from upstream face concrete wall 50cm, is spaced 50～100cm between two copper seals,
Described drain pipe is apart from the copper seal 50cm of nearly back side.
Described copper seal is processed using soft state pure copper strips, and copper strips thickness is 1.8～1.6mm, the nose of copper seal
Sub- opening is arranged towards the upstream face junction of the edges of two sheets of paper, and the both wings of copper seal imbed the concrete block 20～25cm of both sides, copper seal
Filled bitumen flax silk being closed by adhesive tape in nose opening.
Described grout pipe adopts seamless steel pipe to make, caliber 4～5cm, and pipe shaft has a hole of Φ 10mm, and pitch-row 10～
15cm, in quincuncial arrangement.
Described drain pipe adopts non-fine concrete prefabricated, caliber 6～8cm.
The beneficial effects of the utility model are：1st, this utility model pre-plugged grout pipe, later stage between twice sealing
Copper seal region can be carried out with reinforcement of being in the milk, stagnant water effect is reliable.2nd, this utility model buries in advance in copper seal downstream
If drain pipe, residual leak water in seam can be collected and cause in drainage system it is ensured that inside configuration environmental drying is clean and tidy.3rd, this practicality
New water-proof scheme is simple, grout pipe and drain pipe all can field fabrication, construction and installation are simple.

Specific embodiment
This utility model is a kind of water sealing structure for concrete for hydraulic structure movement joint, by twice copper seal 2, grout pipe
4th, drain pipe 5 and grouting material composition.
Copper seal 2 is processed using soft state pure copper strips, and copper strips thickness is 1.8～1.6mm, and copper seal is in " } " type,
As shown in figure 3, Bituminous hemp fiber 6 fills up blend compounds band paper 7 and closes in nose.
Grout pipe 4 adopts seamless steel pipe to make, caliber 4～5cm, as shown in figure 4, pipe shaft has the hole 4-1 of Φ 10mm,
Pitch-row 10～15cm, in quincuncial arrangement.
Drain pipe 5 adopts non-fine concrete prefabricated, caliber 6～8cm.
Grouting material adopts soluble polyurethane material, is elastomer after consolidation, and can water-swellable.
Implementation process of the present utility model：Because of the setting of movement joint 1, xoncrete structure 3 is divided into two parts in left and right.?
Before concreting, as shown in Fig. 2 imbedding twice copper seal 2, grout pipe 4 and drain pipe 5 in advance along movement joint 1, and take
Reliable erection fixation.
Copper seal 2 junction of the edges of two sheets of paper is arranged, 20～25cm in every side embedded concrete structure 3.First copper seal distance
Upstream face 50cm, is spaced 50～100cm between twice copper seal, nose opening is towards inflow direction.Copper seal 2 should be along change
