Description
Technical field
The present invention relates to underground construction field, is that the diaphragm wall of shared same diaphragm wall in the middle of a kind of two Adjacent Pits is to support built-in fitting construction method specifically.
Background technology
Share same diaphragm wall in the middle of two Adjacent Pits and make supporting and protection structure, and realize synchronous excavation and construction, for ensureing the safe construction at the shared diaphragm wall vertically needed under multiple tracks supporting condition and foundation ditch, the accurate centering of axial force of the supports of common land wall both sides foundation ditch should be guaranteed, to realize the pressure effect that ground wall only bears supporting member.Reach this point, steel supporting component must be instructed to be in place to measure, but because steel supporting component is long, large heavier again, installed by loop wheel machine and not easily accurately put in place, and the site operation regular hour need be taken, namely at the construction field (site) implement difficulty large, long in time limit, be difficult to accurately be in place.
Summary of the invention
The object of this invention is to provide a kind of diaphragm wall of constructability to support built-in fitting construction method.
To achieve these goals, technical scheme of the present invention is: a kind of diaphragm wall, to support built-in fitting construction method, is characterized in that the method comprises the following steps: A, make support built-in fitting in advance; B, with diaphragm wall fabrication of reinforcing cage while this is formed integrally to support installation of embedded parts in reinforcing cage; C, lifting reinforcing cage are seated in the diaphragm wall deep trouth formed in advance, then concreting in deep trouth; D, carry out soil mass of foundation pit excavation construction; E, be excavated to support built-in fitting time cut top layer plain concrete in time, erecting and welding fixing steel plate also installs bracing members.
The present invention utilizes support built-in fitting, install convenient, do not need to measure, axial force of the supports can accurate centering, to reach safety, convenient construction, the object of saving duration.

Detailed description of the invention
The present invention is described further as follows by reference to the accompanying drawings with case history.
The two pieces of bracing members flange 1 be arranged in parallel are comprised to support built-in fitting, the exterior bottom of two pieces of bracing members flange 1 is respectively equipped with one piece of absolute altitude locating piece 2, be provided with sleeve pipe 6 between two pieces of bracing members flange 1, the two ends, outside of two pieces of bracing members flange 1 are equipped with one piece to support built-in fitting locating piece 4.Also be provided with when some connecting reinforcement 5(make support built-in fitting soldered between described two pieces of bracing members flange 1).Fixing steel plate 3 is arranged on absolute altitude locating piece 2.Bracing members 7 ends rest is on fixing steel plate 3, and described bracing members 7 two pieces of the same side to support built-in fitting locating piece 4 between, described bracing members end is provided with screw hole, screw rod, through after the sleeve pipe 6 screw hole of bracing members end and two pieces of bracing members flange 1, is fixed with pad and nut.
In the middle of certain two engineering shares, supporting and protection structure made by diaphragm wall, and former design scheme is that two foundation ditches of two engineerings are cut the earth, agent structure stage construction, after due to the duration tight, owner requires that namely two engineering synchronism constructions synchronously carry out excavation of foundation pit.
Be designed to realize synchronous construction excavation, adopt diaphragm wall (being called for short ground wall) both sides foundation ditch to realize support, in shared Diaphragm Wall Support Structure, namely devise diaphragm wall to support built-in fitting.
As shown in the figure, entirely wall is made up of three parts support built-in fitting, is respectively built-in fitting, fixing steel plate and to wearing bolt.Built-in fitting comprises the rhombic steel plate in two pieces of bracing members flange 1(of ground wall 8 liang of side external surfaces and the present embodiment), each one piece of the every side of absolute altitude locating piece 2(, for determining fixing steel plate 3 elevation), to support each two pieces of the every side of built-in fitting locating piece 4(, for controlling during fabrication of reinforcing cage support built-in fitting location), connecting reinforcement 5 and sleeve pipe 6(be used for wearing bolt 9), each component mutually welding production forms one, as shown in the figure.Fixing steel plate 3 is triangular steel plate, as shown in the figure, fixing steel plate should be welded into one with absolute altitude locating piece 2 to after cutting top layer plain concrete during support built-in fitting at excavation of foundation pit, bracing members 7 end is shelved by fixing steel plate 3 and is located and be located at two pieces between support built-in fitting locating piece 4, removable bracing members 7 end makes the screw hole of described bracing members end and the bolt hole centering of sleeve pipe 6, after both sides bracing members is in place, screw rod passes through sleeve pipe 6, can install wearing bolt 9 and by fastening nuts diaphragm wall both sides bracing members.
A kind of diaphragm wall, to support built-in fitting construction method, is characterized in that the method comprises the following steps: A, make support built-in fitting in advance; B, with diaphragm wall fabrication of reinforcing cage while this is formed one to support installation of embedded parts in reinforcing cage, mounting method adopts welding or directly shelves and fixes, and only needs to be fixed in reinforcing cage interior; C, lifting reinforcing cage are seated in the diaphragm wall deep trouth formed in advance, then concreting in deep trouth; D, after concrete curing, carry out soil mass of foundation pit excavation construction; E, be excavated to support built-in fitting time cut top layer plain concrete in time, erecting and welding fixing steel plate also installs bracing members.
According to this embodiment, the spacing between described two pieces of bracing members flange 1 is by the THICKNESS CONTROL of ground wall, and the thickness of described bracing members flange 1 is considered by actual conditions, generally can be 18 ~ 22mm, and the described thickness to support built-in fitting locating piece 4 is 8 ~ 12mm.Groove is adopted to weld bottom described absolute altitude locating piece 2 with bottom bracing members flange 1.By absolute altitude locating piece 2, fixing steel plate 3 is welded on bracing members flange 1.Bracing members flange 1 is provided with casing pipe hole opening, and the tube wall of sleeve pipe 6 is welded on the casing pipe hole opening position of bracing members flange 1 by weld all around.As shown in the figure, four angles of described bracing members flange 1 arrange sleeve pipe, and wherein each angle arranges two sleeve pipes, and the caliber of described sleeve pipe is determined by connecting screw rod diameter, and the screw diameter arranged in sleeve pipe is 16 ~ 20mm.Be connected with between described two bracing members flange 1 when some D25 diameter connecting reinforcement 5(make support built-in fitting and weld), the horizontal spacing between two adjacent connecting reinforcements and longitudinal pitch are respectively between 150 ~ 250mm.Connecting reinforcement diameter 20 ~ 30mm.
