Abstract
The utility model discloses a semi-overlapped underground structure for cut and cover tunneling. The semi-overlapped underground structure comprises an underground continuous wall and lining side walls, wherein the lining side walls are connected with lining plates having a supporting effect; the underground continuous wall is connected and fixed with the lining plates through steel bar connectors and steel bars. Spraying film waterproof layers are arranged on the contact surfaces of the underground continuous wall and the lining side walls. According to the semi-overlapped underground structure disclosed by the utility model, a lining top plate, a lining middle plate, a lining bottom plate and the underground continuous wall form an overlapped structure to commonly bear a bent torque and a shearing force of a node part so that the thickness of a lining structure can be effectively reduced; compared with a composite structure, the economical efficiency is good; the spraying film waterproof layers are arranged on the contact surfaces of the underground continuous wall and the lining side walls so that the effects of reducing cracks generated in a pouring process of lining walls and improving the waterproof quality are realized when being compared with those of an overlapped wall.
Description
Technical field
The utility model relates to the underground structure of underground cut and cover tunneling, is specially adapted to adopt diaphragm wall as half superimposed underground structure of the cut and cover tunneling of going along with sb. to guard him.
Background technology
In adopting the underground construction of cut and cover tunneling, can be divided into three kinds of structure typess according to the stressed relation of space enclosing structure and inner lining structure: single structure, composite construction and iterative structure, all there are corresponding pluses and minuses in three kinds of structures:
1) single structure be with space enclosing structure directly as the side wall of agent structure, bear simultaneously the construction period and the operation phase whole load, internal construction is not established inwall.Single structure generally adopts diaphragm wall as space enclosing structure, and due to without inwall, its waterproof effect is poor, and because the construction quality of diaphragm wall is wayward, the poor durability of structure, present domestic underground water is grown the area and is seldom adopted this structure.
2) composite construction is between space enclosing structure and inner lining structure, splash guard to be set, and space enclosing structure had both been born the load of construction period, runs the phase load as a part and the inwall shared of agent structure again.Owing to adopting the splash guard isolation between space enclosing structure and inner lining structure, thereby inner lining structure can form totally-enclosed waterproof, and waterproof effect is better; But can't Transfer of Shear due to the bonding surface of inwall and space enclosing structure, inner lining structure needs larger thickness, and when inner support is more, splash guard need multiple welding affects the integral waterproofing effect.
3) iterative structure is that splash guard is not set between space enclosing structure and inwall, and its bonding surface carries out dabbing to be processed and has shear bar to connect.Because the bonding surface of iterative structure and space enclosing structure can Transfer of Shear, thereby inwall and space enclosing structure be overall structure, and desired structure thickness is less, better economy.But without waterproofing course, the waterproofing system of inner lining structure does not seal due to bonding surface, and waterproof effect is poor, particularly the inwall concrete directly is cast in the space enclosing structure inner surface, is subjected to the constraint of space enclosing structure during its concrete setting, as easy as rolling off a log generation crack, reduce durability, also increased the risk of leaking.
Summary of the invention
The purpose of this utility model is to provide a kind of half superimposed underground structure of cut and cover tunneling, can strengthen the globality of inner lining structure and space enclosing structure, reduces the thickness of inner lining structure, improves the waterproof reliability of waterproofing course.
For achieving the above object, half superimposed underground structure of the designed a kind of cut and cover tunneling of the utility model, it comprises diaphragm wall and liner side wall, is connected with passive interior lining panel on described liner side wall; Be connected and fixed by reinforcing bar connector and reinforcing bar between described diaphragm wall and interior lining panel.
Further, the contact surface of described diaphragm wall and liner side wall is provided with spray film waterproofing course.
Again further, the junction of described interior lining panel and liner side wall is provided with vertical constuction joint.
Again further, described interior lining panel comprises plate and interior underboarding in the liner top board of arranging successively from top to bottom along liner side wall vertical direction, one or more liner.
Again further, described interior lining panel comprises liner top board, the interior underboarding of arranging successively from top to bottom along liner side wall vertical direction.
The utility model is connected diaphragm wall by reinforcing bar connector, reinforcing bar are set with the inner lining structure at interior lining panel place, form the Type Composite Structure System of position of joints, to reach diaphragm wall and inner lining structure in the purpose of shared load operation stage; (this constuction joint is arranged definite according to inner support by spray film waterproofing course being set between diaphragm wall and liner side wall and being provided with vertical constuction joint in interior lining panel and liner side wall junction, can not arrange during the execution conditions license), reduce to reach inwall produces the crack, improves waterproof quality in casting process effect.
The beneficial effects of the utility model:
1. interior lining panel and diaphragm wall are iterative structure, jointly bear moment of flexure and the shearing of position of joints, can effectively reduce the thickness of inner lining structure, compare good economy performance with composite construction;
2. the inner lining structure side wall spray film waterproofing course after-pouring is set, is compared with superimposed wall, can reach to reduce inwall produces the crack, improves waterproof quality in casting process effect.；
3. the contact surface of diaphragm wall and liner side wall is provided with spray film waterproofing course, spray film waterproofing course has self-healing function, although the reinforcing bar of position of joints has penetrated waterproofing course, little on water tight integrity and waterproof effect impact, avoided the poor shortcoming of iterative structure waterproof effect;
4. spray film construction of waterproof layer technique simple, convenient, thereby avoided the composite construction splash guard to need multiple welding to affect the shortcoming of waterproof effect at the inner support position.
