Description
Technical field
The utility model relates to a kind of underground construction, particularly a kind of water-stopping structure of underground waterproof engineering.
Background technology
During existing water conservancy or other underground waterproof engineering are constructed, its adjacent structure all adopts copper sheet setting-in to carry out sealing, current known construction method is all " pre-buried method ", namely before concrete placings pre-buried copper sheet half, second half give over to adjacent structure connect method.Adopt " pre-buried method " construction, first want excavation construction, excavation operation can cause harmful effect to the ground of surrounding, can cause the problems such as surrounding building differential settlement, for overcoming this problem, a kind of top-down construction method is also had in prior art, namely first face down from ground and excavate the slotted eye of certain depth, arrange in the circle that connects between adjacent slot, to hole concrete perfusion in backward boring, firm diaphragm wall is formed after solidification, diaphragm wall generally encloses closed shape, excavation construction is carried out again after structure completes, the harmful effect to Adjacent Buildings can be avoided, it is applied in subway station, basement, during supporting and protection structure etc. are built, its problem brought is that copper sheet sealing cannot be pre-buried, expanded rubber can only be adopted at present to be installed between the shrinkage joint of adjacent structure, the expansion of expanded rubber is utilized to carry out sealing.It affected by field condition, building surface planeness, method of attachment, self-strength and life-span etc., was difficult to effectively solve leakage problems.
Utility model content
The purpose of this utility model is to provide a kind of underground waterproof engineering water-stopping structure, is intended to solve the difficulty of carrying out the installation of copper sheet sealing in existing concrete structure, to overcome the deficiency of rubber seal in anti-seepage effect in contrary sequence method.
The purpose of this utility model is achieved in that a kind of underground waterproof engineering water-stopping structure, comprises diaphragm wall and concrete floor, leaves shrinkage joint between diaphragm wall and concrete floor, and described diaphragm wall is dug sealing part mounting groove; Be coated with bottom sealing part mounting groove and be brushed with epoxy resin prime coat; Epoxy glue mud layer is coated with on the upside of epoxy resin prime coat, copper sheet sealing part is provided with between diaphragm wall and concrete floor, a bending part is provided with in the middle part of described copper sheet sealing part, described bending part is in shrinkage joint, copper sheet sealing part side is connected on epoxy glue mud layer, above described copper sheet sealing part side, be provided with epoxy mortar layer, epoxy mortar layer fills up the sealing part mounting groove on the upside of copper sheet sealing part, and the opposite side of copper sheet sealing part is embedded in concrete floor.
It improves further and is that described epoxy mortar layer surface smear has closed top layer.
The degree of depth of described sealing part mounting groove is 6 ~ 7cm, and the height of sealing part mounting groove is 12 ~ 15cm.
In the utility model, epoxy resin prime coat can add the switching performance between reinforced concrete and epoxy mortar; Epoxy mortar is made up of epoxy resin and ethylenediamine curing compound, is plastic material, and its cementitiousness is strong, and be easy to hardening time control, after connecting, watertightness performance is good, reliably can be connected with copper sheet; And epoxy mortar is dry material, be convenient to filling.After epoxy mortar primary solidification, form at its surface smear one deck epoxy coating pore and the gap that epoxy mortar can be filled up in closed top layer, reach the effect of closed allround.Finally, coagulate in soil by the coagulation opposite side of copper sheet sealing part being cast in adjacent structure, also good sealing effectiveness can be reached at the opposite side of copper sheet sealing part, the bending part of copper sheet sealing part is stayed in shrinkage joint, the situation such as differential settlement, shrinkage strain can be compensated, ensure that there is good sealed waterproof effect.This structure is used for, in the construction of contrary sequence method underground waterproof engineering, having the sealed waterproof effect same with pre-buried method.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 diaphragm wall, 2 concrete floors, 3 shrinkage joint, 4 copper sheet sealing parts, 5 epoxy resin prime coats, 6 epoxy glue mud layers, 7 epoxy mortar layers, 8 close top layer.
Detailed description of the invention
As shown in Figure 1, be underground waterproof engineering water-stopping structure, comprise diaphragm wall 1 and concrete floor 2, leave shrinkage joint 3 between diaphragm wall 1 and concrete floor 2, diaphragm wall 1 is dug sealing part mounting groove; The degree of depth of sealing part mounting groove is 6 ~ 7cm, is highly 12 ~ 15cm.Be coated with bottom sealing part mounting groove and be brushed with epoxy resin prime coat 5; Epoxy glue mud layer 6 is coated with on the upside of epoxy resin prime coat 5, copper sheet sealing part 4 is provided with between diaphragm wall 1 and concrete floor 2, a bending part is provided with in the middle part of copper sheet sealing part 4, this bending part is in shrinkage joint 3, copper sheet sealing part 4 side is connected on epoxy glue mud layer 6, above described copper sheet sealing part side, be provided with epoxy mortar layer 7, epoxy mortar layer 7 fills up the sealing part mounting groove on the upside of copper sheet sealing part, and the opposite side of copper sheet sealing part 4 is embedded in concrete floor.Also be coated with epoxy coating on epoxy mortar layer 7 surface and form closed top layer 8.
During its construction, in turn include the following steps:
1) build diaphragm wall 1, then carry out soil excavation, expose the inner side body of wall of diaphragm wall 1, body of wall needs the position of sealing dig sealing part mounting groove; The degree of depth of sealing part mounting groove is 6 ~ 7cm, is limited not destroy reinforcement cover, and the height of sealing part mounting groove is 12 ~ 15cm.
