Abstract
The utility model relates to an underground works construction field specifically is a modular curtain, including steel pipe and connecting piece, the steel pipe include interior steel pipe and cover establish including the outside outer steel pipe of steel pipe, interior steel pipe passes through floor fixed connection with outer steel pipe, the both sides of outer steel pipe are equipped with the interpolation slit, the both sides of connecting piece are equipped with the limiting plate, and the connecting piece inserts in the interpolation slit of two adjacent outer steel pipes. Compared with the prior art, the utility model discloses modular curtain and underground continuous wall's beneficial effect does: simple structure, cost are hanged down, the rigidity is high and can form a continuous mask, and it is effectual to keep off soil, can directly excavate the soil body under this modular curtain's of the strutting.
Description
Technical field
The utility model relates to underground engineering construction field, specifically a kind of combined type curtain.
Background technology
Current underground construction preliminary bracing mainly adopts the support forms such as pipe shed support, grid+ductule+in-network processing supporting, cement mixing method supporting, freezing process supporting.Wherein, pipe shed support can not form continuous print and prop up mask, and keep off native weak effect, rigidity is low, can not realize the soil body and directly excavate.Grid+ductule+in-network processing supporting construction is complicated, and cost is higher.Cement mixing method, the equal cost of freezing process supporting are higher, and directly excavate under being difficult to realize supporting.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides that a kind of structure is simple, cost is low, rigidity is high and can form the technical scheme of the combined type curtain in continuous supporting face.
Technical problem to be solved in the utility model realizes by the following technical solutions: a kind of combined type curtain, comprise steel pipe and connector, described steel pipe comprises interior steel pipe and is set in the outer steel pipe of interior steel pipe outside, described interior steel pipe is fixedly connected with by floor with outer steel pipe, and the both sides of described outer steel pipe are provided with interpolation slit; The both sides of described connector are provided with limiting plate, and connector inserts in the interpolation slit of adjacent two outer steel pipes.During construction, treat to hole in supporting position first in underground construction, then steel pipe is inserted in the hole, then connector is inserted in the interpolation slit of adjacent outer steel pipe, namely form combined type curtain of the present utility model.
The technical solution of the utility model also has: described interior steel pipe is provided with extravasating hole.Adopt the technical program, slip casting in interior steel pipe, space between steel pipe and outer steel pipe in cement paste overflows and fills from extravasating hole, then from interpolation slit, spilling is combined with connector and surrounding soil and solidifies, and improves the rigidity of combined type curtain.
The technical solution of the utility model also has: the bottom of described connector is provided with stiffener.Adopt the technical program, stiffener can be combined with cement paste and solidify, and can increase the contact area with surrounding soil, thus improves the rigidity of combined type curtain.
The technical solution of the utility model also has: described stiffener is the arc be bent upwards.
The technical solution of the utility model also has: described interior steel pipe is fixedly connected with by two panels floor with outer steel pipe.
The technical solution of the utility model also has: described floor is fixed with interior steel pipe and outer steel-pipe welding respectively.
Relative to prior art, the beneficial effect of the utility model combined type curtain and diaphragm wall is: structure is simple, cost is low, rigidity is high and can form continuous print and prop up mask, gear soil is effective, directly can excavate the soil body under the supporting of this combined type curtain.

Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, with reference to the accompanying drawings the utility model detailed description of the invention is described further below.
Fig. 1, Fig. 2 show embodiment one of the present utility model, as shown in the figure, a kind of combined type curtain, comprise steel pipe 1 and connector 2, described steel pipe 1 comprises interior steel pipe 3 and is set in the outer steel pipe 4 of interior steel pipe 3 outside, described interior steel pipe 3 is fixedly connected with by two panels floor 5 with outer steel pipe 4, and described floor 5 is welded and fixed with interior steel pipe 3 and outer steel pipe 4 respectively, and the both sides of described outer steel pipe 4 are provided with interpolation slit 6; The both sides of described connector 2 are provided with limiting plate 7, and connector 2 inserts in the interpolation slit 6 of adjacent two outer steel pipes 4.
During construction, treat to hole in supporting position first in underground construction, then steel pipe 1 is inserted in the hole, then connector 2 is inserted in the interpolation slit 6 of adjacent outer steel pipe 4, namely form combined type curtain of the present utility model.
Fig. 3, Fig. 4 show embodiment two of the present utility model, as shown in the figure, are different from embodiment one, and the interior steel pipe 3 in embodiment two is provided with extravasating hole, and the bottom of connector 2 is provided with the stiffener 8 of the arc be bent upwards.By slip casting in interior steel pipe 3, space between steel pipe 3 and outer steel pipe 4 in cement paste overflows and fills from extravasating hole, then overflows to be combined with connector 2 and surrounding soil and solidifies, improve the rigidity of combined type curtain from interpolation slit 6.
By reference to the accompanying drawings embodiment of the present utility model is elaborated above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
