Detailed Description
As shown in fig. 2, a bridge crack reinforcing apparatus includes foundation fixing portions 21 at left and right sides, the fixing portions 21 are vertically fixed in a foundation, the upper, middle and lower layers of the foundation fixing portion 21 at one side and the foundation fixing portion 21 at the other side all pass through a beam 30, wherein the middle layer of the foundation fixing portion 21 passes through at least one set of beams 30, if the gap is deep, the middle layer can also be provided with several sets of beams 30 arranged up and down (for convenience of drawing, only one beam 30 is drawn in fig. 2).
The fixing portion 21 is a vertical beam (or a vertical column).
The cross beam 30 comprises three sections, wherein two side ends are both provided with connecting columns 31, the middle part is provided with tension springs 32, one end of each connecting column 31 is provided with a fixing ring 311, the fixing ring 311 is sleeved on the vertical beam (the fixing part 21), the other end of each connecting column 31 is provided with a connecting hole 312, and two ends of each tension spring 32 are respectively fixed in the connecting holes 312 on two sides.
The whole connecting column 31 is buried in the roadbed, the inner end part of the connecting column is exposed in the crack 11, the sleeve 33 is sleeved outside the tension spring 32, two ends of the sleeve 33 are hermetically fixed at one end of the connecting column 31, and a cavity where the tension spring 32 is located is a sealed cavity.
For ease of installation, the sleeve 33 comprises two symmetrical sleeve halves.
When the foundation fixing part 21 on one side is fixed to the foundation fixing part 21 on the other side, there are two cases:
as shown in fig. 4, the foundation-fixing portion 21 of one side is fixed to only one foundation-fixing portion 21 of the other side, and each set of fixed foundation-fixing portions 21 is independent.
As shown in fig. 5, the foundation fixing portion 21 on one side is fixed to the two foundation fixing portions 21 on the other side. Two tension springs 32 are connected to the connecting columns 31 of the remaining foundation fixing portions 21 except for the two foundation fixing portions 21 at the ends of the slit 11, so that the overall installed cross beam 30 has a W-shaped plan view.
Obviously, in the latter method, the traction force on the foundations on the two sides is greater and safer.
Referring to fig. 1-3, when the roadbed 10 is provided with long slits 11 along the direction of the road bridge, the installation method is as follows:
firstly, cleaning broken and loosened foundation residues in the crack 11 until foundations (a left foundation 12 and a right foundation 13) on two sides are firm foundations;
secondly, measuring the length and the depth of the crack 11, and calculating the number of the needed foundation fixing parts 21 and the needed beams 30;
thirdly, drilling a vertical hole 15 at the position of a foundation fixing part 21 on the left foundation 12 and the right foundation 13, drilling a transverse hole 16 at the position of a mounting cross beam 30, and mounting the foundation fixing part 21 and a connecting column 31;
fourthly, fixing the vertical holes 15 and the transverse holes 16 with the components inside by structural adhesive;
fifthly, fixing the two ends of the tension spring 32 in the connecting holes 312 at the two sides respectively;
sixthly, installing a sleeve 33;
seventhly, backfilling concrete: and (3) planting reinforcing steel bars 41 on the foundation of the crack surface, and pouring concrete in the crack 11 to harden the concrete.
Therefore, when the landfill is rolled by vehicles, the tension springs can reduce the vibration amplitude of the landfill to two sides, form the prestress of three-dimensional protection, reduce the probability that the roadbed continues to extend to two sides, prevent gaps from continuing to expand and ensure the normal use of roads and bridges.
