preceding method carries out according to the following steps:
1., chisel the layer of concrete that ftractures, sinks with pneumatic pick, and by dark the back fill course cleaning 300mm under layer of concrete;
2., between residue back fill course, vertically squeeze into φ 500mm steel pipe until bearing layer; 3., in the gap of steel pipe and steel pipe, again insert backfill to former backfill absolute altitude;
4., be backfilled to terrace absolute altitude with the thick graded sand and stone of 300mm, area mat is smooth;
5., lay one deck steel mesh reinforcement, steel mesh reinforcement and steel-pipe welding on graded sand and stone layer surface;
6., in extremely former design elevation of steel mesh reinforcement upper layer of concrete;
7., by standard, layer of concrete is carried out to maintenance.
in preceding method, described step 2. in the length of steel pipe when inadequate, allow to lengthen by welding manner.
in preceding method, when described step is inserted backfill in 3. again, require layered rolling compacting, do not allow to be all filled to and require to tamp again after absolute altitude.
in preceding method, the gauze wire cloth of described step in 5. adopts crisscross reinforcing bar binding or is welded, and rebar surface carries out processing of rust removing; Gauze wire cloth and every steel pipe reliably weld.
in preceding method, described step is 6. when at steel mesh reinforcement upper layer of concrete, with vibrating head, concrete is closely knit.
the floor structure forming according to preceding method, comprises foundation ditch; Foundation ditch is provided with back fill course, graded sand and stone layer and reinforced concrete floor from the bottom to top; In back fill course, be provided with equally distributed vertical steel tube, in reinforced concrete floor, be provided with gauze wire cloth.
in aforementioned floor structure, described vertical steel tube lower end extends to underground bearing layer; Vertical steel tube upper end is positioned at reinforced concrete floor.
in aforementioned floor structure, the gauze wire cloth welding in described vertical steel tube upper end and reinforced concrete floor.
compared with prior art, the steel pipe that the present invention uses can adopt common scaffolding steel pipe, with low cost, supports and meets design requirement as bearing stratum; Steel mesh reinforcement also can be connected to form with plain bars, easily buys; Again fill out the easily construction such as backfill, graded sand and stone laying, pouring concrete; Technical scheme integral construction program of the present invention is uncomplicated, simple in structure, easy construction, and effect is remarkable, novel, and the present invention is specially adapted to terrace in use procedure or mini-plant basis to occur the processing after sedimentation, is worthy to be popularized.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
being labeled as in accompanying drawing: 1-back fill course, 2-graded sand and stone layer, 3-reinforced concrete floor, 4-vertical steel tube, 5-gauze wire cloth.
The specific embodiment
below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
a kind of terrace sedimentation processing method, as shown in Figure 1, the method is in existing backfill layer, to squeeze into uniformly one group of vertical reinforcing bar, vertical reinforcing bar bottom contacts with underground bearing layer, steel mesh reinforcement in top and the reinforced concrete floor of vertical reinforcing bar is welded into a whole, by one group of vertical reinforcing bar by the weight transmitting of terrace surface to bearing layer, in case there is sedimentation.
preceding method carries out according to the following steps:
1., chisel the layer of concrete that ftractures, sinks with pneumatic pick, and by dark the back fill course cleaning 300mm under layer of concrete;
2., between residue back fill course, vertically squeeze into φ 500mm steel pipe until bearing layer; 3., in the gap of steel pipe and steel pipe, again insert backfill to former backfill absolute altitude;
4., be backfilled to terrace absolute altitude with the thick graded sand and stone of 300mm, area mat is smooth;
5., lay one deck steel mesh reinforcement, steel mesh reinforcement and steel-pipe welding on graded sand and stone layer surface;
6., in extremely former design elevation of steel mesh reinforcement upper layer of concrete;
7., by standard, layer of concrete is carried out to maintenance.
described step 2. in steel pipe can adopt common scaffolding steel pipe, when the length of steel pipe is inadequate, allow to lengthen by welding manner.When described step is inserted backfill in 3. again, require layered rolling compacting, do not allow to be all filled to and require to tamp again after absolute altitude.The gauze wire cloth of described step in 5. can adopt the crisscross colligation of plain bars or be welded, and rebar surface carries out processing of rust removing; Gauze wire cloth and every steel pipe reliably weld.Described step is 6. when at steel mesh reinforcement upper layer of concrete, with vibrating head, concrete is closely knit.
