Abstract
The utility model discloses a seepage prevention structure used at a combining part of a concrete cofferdam and a permanent building. The seepage prevention structure comprises the permanent building and the concrete cofferdam arranged on the permanent building, wherein expanded sealing rods and cement nails for fixing the expanded sealing rods on the permanent building are arranged at the combining part of the concrete cofferdam and the permanent building. The seepage prevention structure has the benefits that due to the adoption of the expanded sealing rods for preventing seepage, a relatively good seepage prevention effect is achieved in the operation period of the concrete cofferdam, the construction of a dry foundation trench is ensured, the structure of the permanent building is not affected, structural ribs are not affected, meanwhile no residues are left inside the permanent building after the expanded sealing rods are disassembled, a structural plane of the permanent building is flat and free of damage, functions of the permanent building are brought into play, safe operation is ensured, and moreover the seepage prevention structure has the characteristics of convenience and rapidness in mounting, reliable techniques, economy and feasibility.
Description
Technical field
The utility model relates to a kind of leakage preventing structure for concrete cofferdam and permanent building junction, belongs to building leakage preventing structure technical field.
Background technology
In the time of above concrete cofferdam is arranged in permanent building, between the two, very easily seep water in junction conventionally.For guaranteeing foundation ditch dry work; its antiseepage mode generally takes to bury underground copper seal, rubber strip etc. in concrete cofferdam and permanent building; or dabbing processing is carried out to as constuction joint in the two junction, make the two concrete cementing better to reach the object of junction antiseepage.Because concrete cofferdam is generally temporary structure, before the permanent operation of engineering, need to remove, after dismounting, will leave the residues such as part copper seal, rubber strip in permanent building, or after concrete cofferdam dismounting, junction is constuction joint, seam face is uneven, do not reach permanent building service requirement, affect the normal performance of permanent building function and safe operation; In addition, due to more in copper seal or rubber strip embedding permanent building structure, affect structural integrity, and cause permanent building structure reinforcing bars difficult arrangement.Therefore, the leakage preventing structure of existing concrete cofferdam and permanent building junction or not ideal enough.
Summary of the invention
The purpose of this utility model is to provide a kind of leakage preventing structure for concrete cofferdam and permanent building junction, can overcome the deficiencies in the prior art, can reach good anti-seepage effect at concrete cofferdam run duration, guarantees the construction on the dry ground of foundation ditch.
The purpose of this utility model is achieved through the following technical solutions: a kind of leakage preventing structure for concrete cofferdam and permanent building junction, comprise permanent building and be arranged in the concrete cofferdam on permanent building, described concrete cofferdam and the junction of permanent building are provided with expansion sealing strip and expansion sealing strip are fixed on to the cement nail on permanent building.
Described concrete cofferdam is grinding concrete structure or normal concrete structure.
The beneficial effects of the utility model are: adopt expansion sealing strip antiseepage, at concrete cofferdam run duration, reached good anti-seepage effect, guaranteed the construction on the dry ground of foundation ditch, do not occupy permanent building structure, structural reinforcement is unaffected, expansion sealing strip can not leave residue after removing in permanent building simultaneously, guarantee that permanent building structural plane is smooth harmless, the function of permanent building obtains normally bringing into play safe operation, and have install convenient, technology is reliable, economically viable feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the scheme of installation of the utility model expansion sealing strip.
Wherein, 1-concrete cofferdam, 2-permanent building, 3-expansion sealing strip, 4-cement nail.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As shown in Figure 1, Figure 2, a kind of leakage preventing structure for concrete cofferdam and permanent building junction, comprise permanent building 2 and be arranged in the concrete cofferdam 1 on permanent building 2, described concrete cofferdam 1 and the junction of permanent building 2 are provided with expansion sealing strip 3 and expansion sealing strip 3 are fixed on to the cement nail 4 on permanent building 2.
Described concrete cofferdam 1 is grinding concrete structure or normal concrete structure.
After expansion sealing strip 3 is met water, start to expand, fit tightly with concrete cofferdam 1 and permanent building 2, prevented the junction infiltration of concrete cofferdam 1 with permanent building 2, avoid water to flow into foundation ditch and affect construction.
Compared to existing technology, the utility model adopts expansion sealing strip antiseepage, leakage preventing structure is simple, it is convenient to install, antiseepage quality is easy to guarantee, because expansion sealing strip cross dimensions is less, and do not embed in permanent building, can not affect permanent building structural plane planeness, also can not affect concrete structure arrangement of reinforcement, expansion sealing strip can not leave residue after removing and affect its normal function performance and safe operation in permanent building simultaneously; Expansion sealing strip expands after meeting water, fits tightly with concrete cofferdam and permanent building, and anti-seepage effect reliability is strong.
The utility model is not only simple in structure, safe, reliable, invest littlely, reached good anti-seepage effect, and economic and practical, after dismounting, can not affect the normal performance of permanent building function and safe operation, for concrete cofferdam and permanent building junction leakage preventing structure have been established technical foundation.
Claims (2)
1. the leakage preventing structure for concrete cofferdam and permanent building junction, comprise permanent building (2) and be arranged in the concrete cofferdam (1) on permanent building (2), it is characterized in that: the junction of described concrete cofferdam (1) and permanent building (2) is provided with expansion sealing strip (3) and expansion sealing strip (3) is fixed on to the cement nail (4) on permanent building (2).
