Description
Technical field
Invention belongs to science of bridge building field, is related to a kind of anchorage of large-tonnage Hoisting with Cableway System for bridge construction, special
It is not the large-tonnage Hoisting with Cableway System Combined light anchorage that soil body lateral pressure can be made full use of to carry and construction method.
Background technique
Hoisting with Cableway System is the common hanging device of bridge construction, and anchorage is the important load-carrying construction of Hoisting with Cableway System
Object, the type of anchorage have gravity type, tunnel type, rock anchor formula etc..Since tunnel type, rock anchor formula anchorage have landform and geological conditions
Special requirement, therefore gravity anchor is the anchorage form being most widely used, it is rubbed by the level that anchorage self weight generates
Power is wiped to resist main rope horizontal direction component.In recent years, arch bridge erection lesser for tonnage also develops some light
Type anchorage structures, using the reinforced concrete pile in buried rock stratum as primary load bearing structure, so that concrete material dosage is saved,
Reduce anchorage volume, reduces construction cost.
For large-tonnage Hoisting with Cableway System, since its rated load weight is big, the Suo Li of main rope often reaches kiloton or more.If adopting
With gravity anchor, then the volume of anchorage will be very big, and concrete amount is more, and takes up a large area, and is unfavorable for environmental protection；According to
Conventional light anchorage structure, then be difficult to provide enough bearing capacities.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the shortcomings of existing anchorage structures, provide that a kind of structure is simple, peace
Full Combined light anchorage and its construction method reliable, easy for construction, reduce the dosage of anchorage concrete, abundant Combining with terrain
Condition allows massif to participate in stress jointly, provides enough bearing capacities.
To solve the problems, such as techniques described above, the technical solution adopted by the present invention is that, one kind being used for large-tonnage cable crane system
Bottom beam is arranged in the Combined light anchorage of system, including club-footed pile, bottom plate, parados, floor, batter post and anchor beam, the bottom plate lower section,
Small floor is arranged in the back soil face of the parados, and the anchor beam is fixed on the side of batter post by built-in fitting, and wirerope bypasses anchor beam
After anchor.
Further, club-footed pile of the present invention, bottom plate, parados, floor, batter post, bottom beam, small floor etc. are one-piece casting
Reinforced concrete member；
Further, the longitudinal reinforcement of the club-footed pile and batter post is elongated arrangement.
Further, the anchor beam is welding steel member, and arc plate, arc plate is arranged at the position that anchor beam is contacted with wirerope
Internal fill concrete.
Further, a certain number of element soil can be filled out on the plate top surface.
Further, the parados meets the soil body after native face is former massif or is backfilling and compacted, to utilize earth pressure balance
The part of horizontal component of wirerope.
Preferably, artificial digging pile can be used in hole-expanding pile, stake diameter can be 2.0m~2.0m, and bellend diameter is than pile body
Big 1.5m of diameter or so.
A kind of construction method of Combined light anchorage, comprising the following steps:
Step 1) acts on total Suo Li T of anchorage according to cable crane under least favorable hoist state, determines Combined light
Type anchorage structures need vertical bearing capacity and horizontal direction bearing capacity to be offered；In conjunction with Combined light anchorage structures and landform,
Geological conditions carries out bearing capacity calculation, determines the length of club-footed pile and the specific size of anchorage structures other components, according to
Stress or detailing requiments configuration reinforcement；
Step 2) excavates the hole body of club-footed pile and club-footed pile of constructing, and the longitudinal reinforcement of club-footed pile and batter post is elongated arrangement；
Step 3) excavates anchorage structures foundation pit, binds anchorage structures reinforcing bar, and built-in fitting, and casting concrete, coagulation is arranged
Soil wants integral concreting to form；
Step 4) makes anchor beam, and anchor beam is welded on the pre-embedded steel slab of batter post side, and stiffened steel plates are arranged.
Step 5) fills out plain soil above plate top surface, and the steel such as main rope, hoisting rope, hauling rope and wind cable are hung on anchor beam
Cord completes anchoring
Preferably, when total Suo Li T is 11000kN~12000kN, taking club-footed pile pile body diameter is 2.0m, and bellend is straight
Diameter is 3.5m, base plate thickness 1.0m, to length is 9.1m along rope, and parados is highly 7.0m with a thickness of 1.0m, floor with a thickness of
1.5m, batter post cross dimensions are 2.0 × 2.0m, and the box-shaped primary structure member of anchor beam uses to be welded with a thickness of the Q345B steel plate of 30mm
It is formed, box section height is 0.8m.
Preferably, in the step 1), total Suo Li T includes the active force of main rope, hoisting rope, hauling rope and wind cable.
Preferably, in the step 2), when the anchorage of Hoisting with Cableway System is set on massif, using the side of manually digging hole
Formula pore-forming.
Combined light anchorage of the present invention, the steel such as main rope, hoisting rope, hauling rope, wind cable of Hoisting with Cableway System
Cord is anchored on anchor beam, and anchor beam and built-in fitting are welded to connect, and Jiang Suoli is transferred to built-in fitting, is transferred to tiltedly by built-in fitting
Column, motive power is transferred to club-footed pile, bottom plate and floor by batter post, and is finally transmitted to foundation soil body.The horizontal direction of Suo Li
Component is mainly met passive earth pressure, the club-footed pile in native face by the horizontal direction frictional force between anchorage structures bottom plate and the soil body, parados
Passive earth pressure of side etc. partial equilibrium；The vertical force component of Suo Li is mainly by filling out above the self weight of anchorage structures, bottom plate
Soil self weight, club-footed pile side frictional resistance etc. partial equilibrium.
The invention has the advantages that the Combined light anchorage structures fill while giving full play to itself bearing capacity
Divide Combining with terrain condition, the Suo Li of a big chunk Hoisting with Cableway System is balanced using the passive earth pressure of the soil body after wall, thus aobvious
The self weight and volume for reducing anchorage structures are write, with structure is simple, bearing capacity is strong, safe and reliable, easy for construction, adaptability
The advantages that good, low in cost, has significant economy and applicability.
