Embodiment 1
[0023] see figure 1 , the product of the embodiment of the present invention includes the first prefabricated panel 1, the second prefabricated panel 2, the third prefabricated panel 3, the fourth prefabricated panel 4, the first adjustable rotating rod 5, the second adjustable rotating rod 6, the insertion rod 7. The first embedded sleeve 8 and the second embedded sleeve 9. The first prefabricated slab 1, the second prefabricated slab 2, the third prefabricated slab 3, and the fourth prefabricated slab 4 are all reinforced concrete prefabricated slabs with a certain strength. It is a plane, and there is a first embedded sleeve 8 or a second embedded sleeve 9 in the middle of each prefabricated panel; the first embedded sleeve 8 and the second embedded sleeve 9 are high-strength lifting sleeves, It can be penetrated into high-strength steel bars and fixed in reinforced concrete. The inner walls of the first pre-embedded sleeve 8 and the second pre-embedded sleeve 9 are distri...

The invention discloses a novel combined type open caisson and a using method thereof. The technology is suitable for deep foundation support construction for bridge and building foundation in soft soil and sandy soil, operation is easy, safety and feasibility are achieved, so that damage to surrounding environment caused by large-area excavation can be avoided; open caisson foundation construction is achieved through using prefabricated plates, adjustable rotating rods, an inserting rod and pre-buried sleeves; firstly, the site is leveled, two prefabricated plates are hoisted, blade foots areinserted into a preset position, the prefabricated plates are sunk to a certain depth under the action of an external force, and the other two prefabricated plates are hoisted by the same method; then the first adjustable rotating rod and the second adjustable rotating rod are rotated in a rotating mode, the lengths of the adjusting rods are adjusted freely, so that four 45 degree inclined surfaces of the prefabricated plates are completely meshed, and the inserting rod is inserted to be fixed at the moment; and finally, digging or upper stacking is carried out in a closed structure formed bythe four prefabricated plates, so that the prefabricated plates fall to a designed position, after the internal construction of a barrel body structure is completed, the adjustable rotating rods canbe detached, and circulating utilization is achieved.
Description
technical field [0001] The invention relates to the field of foundation construction, in particular to a novel combined caisson and its use method. Background technique [0002] In today's field of foundation engineering, often due to factors such as complex surrounding environment and weak soil quality, large-scale excavation cannot be carried out or large-scale excavation will increase construction costs. In order to overcome the above difficulties, a new type of combined caisson and its application method are designed. By using prefabricated slabs, adjustable rotating rods, inserting rods, and pre-embedded sleeves, deep foundation pit support is realized. The method is simple to operate, safe and feasible, and can avoid large-area excavation. Contents of the invention [0003] The object of the present invention is to provide a new type combined caisson and its use method, through the use of prefabricated plates, adjustable rotating rods, inserting rods, and pre-embedd...
