Logical, in order to make earth enter the first plate body 1 and the second plate body 2 during the press-in soil body
Inner chamber；
The left and right sides of the first plate body 1 caves inward and forms the first groove 11, the second plate body 2
The left and right sides there is the first outwardly plush copper 21, the first plate body 1 and the second plate body 2
Realize removably connecting by the first groove 11 and the first plush copper 21；
The left and right sides of the first plate body 1 is provided with the first screw 4, the left and right sides of the second plate body 2
Being provided with the second screw 5, the first screw 4 and the second screw 5 level are through, and bolt passes first
First plate body 1 and the second plate body 2 are screwed together, to enter one by screw 4 and the second screw 5
Step is by strong first plate body 1 and the bonding strength of the second plate body 2；
The top of the first plate body 1 and the top of the second plate body 2 are equipped with cornical 3, described cornical
In 3 cavitys being horizontally set on the first plate body 1 and the second plate body 2, and the two ends of cornical 3 are solid
It is scheduled on the internal face of the first plate body 1 inner chamber or the second plate body 2 inner chamber；
Before and after first plate body 1, before and after two sides, the second plate body 2, two sides is equipped with through rising
Pull out hole 6.
Present invention additionally comprises turning connecting plate 7, described first plate body 1 and the second plate body 2 are turning
Crook is connected by turning connecting plate 7, and the front facade of described turning connecting plate 7 is provided with and first
The second plush copper 72 that groove 11 matches, the side of described turning connecting plate 7 is provided with and first
The second groove 71 that plush copper 21 matches；Or, the second plush copper 72 is arranged on turning and connects
The side of plate 7, the second groove 71 is arranged on the front facade of turning connecting plate 7.
The angle of the second plush copper 72 and the second groove 71 is 90 °.
Described first screw 4 is arranged vertically on the boss of the first groove 11 both sides,
Described second screw 5 is arranged vertically on the side of the first plush copper 21 both sides.
Or, described first screw 4 is arranged vertically at the bottom land of the first groove 11,
Described second screw 5 is arranged vertically on the convex surface of the first plush copper 21.
On described turning connecting plate 7, corresponding first screw 4 and the second screw 5 are respectively equipped with the 3rd
Screw 9 and the 4th screw 8.
The top of described turning connecting plate 7 also is provided with cornical 3, and cornical 3 is horizontally set on turning
In the cavity of connecting plate 7, and the two ends of cornical 7 are fixed on the inwall of turning connecting plate inner chamber；
Before and after described turning connecting plate 7, two facades also are provided with rising of symmetry and pull out hole 6.
The two ends of described cornical 3 are fixed on the first plate body the 1, second plate body 2 or turning connecting plate
Before and after 7 on the back side of two facades.And cornical 3 distance the first plate body the 1, second plate body 2 or turn
The optimal distance at angle connecting plate 7 top is 0.5m.
On first plate body the 1, second plate body 2 and turning connecting plate 7 rise pull out hole 6 be easy to reclaim
Time, insert to pull out and used equipment.
Cornical 3 is welded on first plate body the 1, second plate body 2 and turning connecting plate 7, both may be used
To strengthen the first plate body the 1, second plate body 2 and intensity of turning connecting plate 7, reduce by the first plate
Body the 1, second plate body 2 and turning connecting plate 7 deform in pressurized process, when also allowing for reclaiming,
Put and pulled out with rope, it is simple to risen and pull out.
In Excavation Process, first by special several the first plate body 1 and second plate bodys 2
Alternately it is pressed into the periphery needing excavation pit, the first plate body 1 and the press-in of the second plate body 2 bottom
The degree of depth exceed foundation depth, the first adjacent plate body 1 and the second plate body 2 are by concavo-convex chimeric
Connect into an entirety, and be bolted the most fixing.Around the corner, turning is used
Connecting plate 7 realizes the first plate body 1 and the connection of turning round of the second plate body 2.Treat that base pit engineering terminates
Time, first plate body the 1, second plate body 2 and turning connecting plate 7 all can be extracted and recycle.
The present invention has simple in construction, it is simple to processing and the advantage of construction and installation, and the first plate
Body the 1, second plate body 2 and turning connecting plate 7 immediately just can play effect after being pressed into the soil body,
Stability is provided for foundation ditch.
Cornical 3 within first plate body the 1, second plate body 2 and turning connecting plate 7 also improves
The intensity of self, decrease first plate body the 1, second plate body 2 and turning connecting plate 7 under press
With the deformation risen during pulling out.
First plate body the 1, second plate body 2 and turning connecting plate 7 are all by concavo-convex fitting connection,
And it is bolted reinforcing further, go along with sb. to guard him intensity high；And concavo-convex fitting connection makes this
The water-impervious performance of bright entirety is strong, does not haves obvious gap.
The present invention is low for the requirement in place, is applicable to most of base pit engineering, is suitable for
Property is good, and globality is strong；Special steel beam column and connector is recyclable reuses, greatly reduces
The cost of foundation pit enclosure, low-carbon environment-friendly.
The construction method of installation of the present invention is as follows:

In, and guarantee that the first plush copper 21 of the second plate body 2 is inserted into the first groove of the first plate body 1
In 11, together with adjacent second plate body 2 is embedded in the first plate body 1, constitute an entirety；
The static pressure compression distance of the first plate body 1 and the second plate body 2 determines according to specification and design.
2) bolt connects: bolt penetrates the first screw 4 and the second plate on the first plate body 1
The second screw 5 on body 2, is twisted the first adjacent plate body 1 and the second plate body 2 by bolt
The most together, several first plate bodys 1 and the second plate body 2 form a more firm entirety.
3) corner connects: static pressure press-in turning connecting plate 7 around the corner, to pass through turning
Connecting plate 7 realizes the first plate body 1 and the connection of turning round of the second plate body 2, by turning connecting plate 7
The second plush copper 72 embed in the first groove 11 of the first plate body 1, the first of the second plate body 2
Plush copper 21 embeds in the second groove 8 of turning connecting plate 7, because the second plush copper 72 and second is recessed
The angle of groove 71 is 90 °, and the first plate body 1 and the second plate body 2 achieve vertical connection；First
Plate body the 1, second plate body 2 and turning connecting plate 7 are fitting to connection and form an entirety.
4) corner adds strong ties: the first screw 4 He being penetrated by bolt on the first plate body 1
The 3rd screw 9 on turning connecting plate 7, meanwhile, penetrates on the second plate body 1 by bolt
The 4th screw 8 on two screws 5 and turning connecting plate 7, by bolt the first plate body 1,
Turning connecting plate 7 and the second plate body 2 are screwed together, the first plate body 1, turning connecting plate 7
Connect further with the second plate body 2, form a more firm entirety.
5) complete whole Foundation Pit Support Engineering according to aforementioned four step, form foundation pit enclosure body
System.
6) after Foundation Pit Support Engineering terminates, by rise pull out arrange insert be previously provided with rise pull out in hole
Or rope is enclosed within cornical 3, by the first plate body 1, turning connecting plate 7 and the second plate body
2 extract recovery one by one.
Content described in this specification embodiment is only the example of the way of realization to inventive concept
Lifting, protection scope of the present invention is not construed as being only limitted to the concrete form of embodiment statement,
Protection scope of the present invention also and can be thought according to present inventive concept in those skilled in the art
The equivalent technologies means arrived.
