The embodiment of lattice column water-tight device in foundation pit described in the utility model described below with reference to the accompanying drawings.Ability
The those of ordinary skill in domain will recognize, can be with various without departing from the spirit and scope of the utility model
Different mode or combinations thereof is modified described embodiment.Therefore, attached drawing and description are regarded as illustrative in nature,
It is not intended to limit the scope of the claims.In addition, in the present specification, attached drawing is drawn not in scale, and identical
Appended drawing reference indicate identical part.
It is hereinafter illustrated by taking foundation pit in subway station as an example, but the present embodiment is not intended to limit it and is applied only to subway
In the foundation pit stood.As shown in Figure 1, subway station lattice column water-tight device includes the waterproof construction and lattice that lattice column passes through bottom plate
Column passes through the waterproof construction of top plate.First illustrate that it passes through the structure of bottom plate below.Be layed in the bottom is waterproof roll 20.?
The surrounding intersection of waterproof roll 20 and lattice column 10 is laid with a circle sealant 30.Preferably, which selects polyurethane
Sealant.The pea gravel concreten protective layer 70 that no less than 5cm thickness is also poured on waterproof roll, in pea gravel concreten protective layer
Bottom plate 40 is poured on 70.Also, in the top of pea gravel concreten protective layer 70, it is swollen that two circles chance water is laid with along 10 surrounding of lattice column
Swollen water-stop glue 60, also, the surrounding of the lattice column 10 between two circle water-swellable water-stop glues 60 is additionally provided at least one circle and stops
Water steel plate 50.The thickness of the steel plate for sealing water is no less than 2mm.Wherein it is preferred to which the steel plate for sealing water 50 is located at lattice column in bottom plate
The middle position of middle length.
Illustrate that lattice column passes through the waterproof construction of top plate below, as shown in Fig. 2, including being laid with two circles along lattice column surrounding
Water-swellable water-stop glue, also, the surrounding of the lattice column between two circle water-swellable water-stop glues is additionally provided at least one circle and stops
Water steel plate.The thickness of the steel plate for sealing water is no less than 2mm.Wherein it is preferred to which the steel plate for sealing water is located at lattice column in top plate 80
The middle position of length.
In one alternate embodiment, being set respectively around the outer wall of lattice column up and down in each circle water-swellable water-stop glue
