According to the invention, the problems of poor integrity and unreliable force transfer of the existing steel support system are solved efficiently, the construction safety is improved, strong operability, safe and fast construction and convenient detachment are achieved, the hoop type adjustable head can be used repeatedly, the unsafe method of driving a steel wedge in the steel support adjustable head to bear and transfer the axial forces via a point contact way is replaced, and promotional values and development foreground are achieved.
Description
Technical field
The present invention relates to a kind of hood type segmented head and job practices thereof for base pit engineering inner support, for steel is supported and applies brace pre axial force, belong to base pit engineering inner support technical field.
Background technology
Foundation ditch steel is supported on extensive use in the construction of subway station cut and cover method, in steel support process is installed, applying controlling stratum horizontal movement of brace pre axial force is significant, and steel supports and applies the segmented head of pre-last item power employing Double-cylinder jack support top or the segmented head of single cylinder jack support top at present.These two kinds of methods are applying after brace pre axial force with jack, squeeze into gad piece, after stable, remove jack.Shortcoming is, steel supports and encloses purlin and adopt to put and contact, mode of transfer force is unreliable, easily cause stress to concentrate and eccentric force, node is unstable, and globality is poor, can not bearing tension, particularly, when stratum soil property is softer, first floor steel support place stratum is prone to the distortion outside foundation ditch, causes steel to support and comes off.Along with being on the increase of China's building foundation pit, the potential safety hazard that steel supports is urgently to be resolved hurrily, and for overcoming the poor shortcoming of steel support system globality, steel support segmented head needs new structure innovation, to strengthen steel support and to enclose purlin, is rigidly connected.
Summary of the invention
Based on the problems referred to above, the present invention proposes a kind of hood type segmented head and job practices thereof for base pit engineering inner support, solved that present steel support system globality is poor, the insecure problem of power transmission, it bears and transmits steel axial force of the supports by the frictional force between anchor ear and inner tube and snap-in force after installation.Hood type segmented head has changed the some connected mode of gad, can bear steel back shaft pressure, also can bear the outwards pulling force of distortion of soil layer, encloses purlin and is improved with steel support globality.
Technical scheme of the present invention is as follows:
A hood type segmented head for base pit engineering inner support, described hood type segmented head comprises anchor ear and inner tube; Described anchor ear is mainly comprised of thick walled steel tube I, anchor ear wing plate, anchor ear place flange, screw block carrier, and thick walled steel tube I one end is welded with anchor ear place flange; In thick walled steel tube I cross section both sides, be symmetrically set with screw block carrier, described screw block carrier respectively with thick walled steel tube I and anchor ear place flange welding; In the upper and lower both sides of thick walled steel tube I, be welded with respectively one group of anchor ear wing plate, every group of anchor ear wing plate is two, and be arranged in parallel, is provided with wing plate high-strength bolt hole and the wing plate floor of putting more energy on anchor ear wing plate; The cut opening that forms in the position of described thick walled steel tube I between two blocks of parallel anchor ear wing plates;
