As depicted in figs. 1 and 2, Fig. 1 is shown as the sectional drawing of the foundation pit enclosure structure of the present embodiment; Fig. 2 is shown as the front view that staff sees from foundation ditch.
The foundation pit enclosure structure of the present embodiment, comprising:
The bottom of campshed 100 is inserted in soil layer successively along campshed 100 arranged in a straight line to be arranged at some of foundation ditch side, and the top of campshed 100 is connected by top syndeton 200, and some campshed 100 intervals are arranged;
Some longitudinal structural parts 300, be arranged at the close foundation ditch side of campshed 100, some longitudinal structural parts 300 are evenly arranged from top to bottom, each longitudinal structural part 300 is all connected with some campsheds 100, every root longitudinal structural part 300 is provided with several anchor cable permanent positions, and each anchor cable permanent position is between adjacent two campsheds 100; Some longitudinal structural part 300 intervals are arranged, and the quantity of longitudinal structural part 300 can adjust according to foundation depth;
Some rotary churning pile anchor cables 400, be arranged at campshed 100 away from foundation ditch side, and homocline is inserted in soil layer, rotary churning pile anchor cable 400 and anchor cable permanent position one_to_one corresponding, some rotary churning pile anchor cables 400 are arranged in several rows from top to bottom, and adjacent two rotary churning pile anchor cables 400 are parallel;
Every root rotary churning pile anchor cable 400 comprises rotary churning pile body 410, anchor cable body 420 is provided with in rotary churning pile body 410, one end of each anchor cable body 420 is fixedly connected with block 500 by one and is connected with the anchor cable permanent position of longitudinal structural part 300, and the quantity being fixedly connected with block 500 is identical with the quantity of rotary churning pile anchor cable 400.
Top of the present utility model syndeton 200 makes some campsheds 100 arranged in a straight line connect as a whole; In order to make rotary churning pile anchor cable 400 can be fixedly connected with campshed 100, arrange some longitudinal structural parts 300, each longitudinal structural part 300 is all connected with some campsheds 100, makes longitudinal structural part 300 be connected as a whole with campshed 100; One end of stretching out from rotary churning pile body 410 of the anchor cable body 420 of each rotary churning pile anchor cable 400 is through the interval adjacent two campsheds 100, and one end of anchor cable body 420 is fixed on the anchor cable permanent position of corresponding longitudinal structural part 300 by being fixedly connected with block 500.
Rotary churning pile anchor cable 400 of the present utility model by longitudinal structural part 300, be fixedly connected with block 500 and be firmly connected with campshed 100, between rotary churning pile anchor cable 400 and weak soil, anchored force is strong, can effectively improve soil body physical and mechanical property.What structure of the present utility model both effectively ensure that deep pit digging goes along with sb. to guard him requirement, effectively shortens the duration, additionally reduces the arrangement space of space enclosing structure, reduce excavation difficulty.
Top syndeton 200 is concrete Guan Liang.This structure ensure that the top of some campsheds 100 firmly can be linked together by concrete Guan Liang.
Be fixedly connected with block 500 for steel waist rail or concrete breast beam.This structure makes one end of anchor cable body 420 be anchored on the anchor cable permanent position of longitudinal structural part 300 by being fixedly connected with block 500, ensures rotary churning pile anchor cable 400 and longitudinal structural part 300 stable connection.
The stake footpath of the rotary churning pile body 410 of rotary churning pile anchor cable 400 is more than or equal to 500mm.Because the stake footpath of rotary churning pile body 410 is comparatively large, make rotary churning pile anchor cable 400 can be supplied to the stable pulling force of campshed 100, and between rotary churning pile body 410 and weak soil, anchored force strengthen.
The tilt angle alpha of rotary churning pile anchor cable 400 is 15 ° to 25 °.The angle of inclination of rotary churning pile anchor cable 400 is configured such that this structure stress is best.
During structure construction of the present utility model, first construct campshed 100 and top syndeton 200, carry out part excavation of foundation pit, construction rotary churning pile anchor cable 400; Be arranged at by anchor cable body 420 in rotary churning pile body 410, the axis of anchor cable body 420 and the axis conllinear of rotary churning pile body 410, this structure makes rotary churning pile anchor cable 400 can be supplied to the stable pulling force of campshed 100; After rotary churning pile anchor cable 400 reaches design age, longitudinal structural part 300 is installed on campshed 100, the anchor cable body 420 of rotary churning pile anchor cable 400 locks by being fixedly connected with block 500 with longitudinal structural part 300, carries out the excavation work of foundation soil below foundation ditch subsequently.
The utility model has following technique effect:
1, the utility model foundation pit enclosure structure, can strengthen anchored force between anchor cable body 420 and weak soil, and what can meet again deep pit digging goes along with sb. to guard him requirement;
2, the utility model space enclosing structure, the degree of depth that can be suitable for excavation of foundation pit is large, reduces the arrangement space of space enclosing structure, alternative traditional to support structure, again reduce excavation difficulty, be particularly useful for periphery situation complexity, limited situation is arranged to support supporting and protection structure;
3, compared with traditional foundation pit enclosure structure constructure scheme, the utility model can not be arranged to support body architecture in foundation ditch, and the increase of construction space in foundation ditch, significantly improves excavation of foundation pit efficiency, for later stage main structure construction provides more rich space; The expense of temporary works measure when simultaneously significantly decreasing construction, reduces construction cost;
To sum up, a kind of foundation pit enclosure structure of the utility model can reduce deep pit digging and go along with sb. to guard him difficulty of construction, significantly shortens the space enclosing structure construction period, effectively solves a deep foundation pit construction excavation difficult problem.The utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
