Description
Technical field
The present invention relates to building trade pile foundation construction field, relate in particular to that the overweight steel reinforcement cage of a kind of caisson manually transfersMethod, the steel reinforcement cage that is applicable to caisson artificial colligation transferring at the construction field (site),
Background technology
Generally, steel reinforcement cage is after factory or on-the-spot colligation complete, then is sling and transferred by crane gear and be arranged onIn pile foundation, but in the time of practice of construction, often there will be scene cannot park crane gear, or the lifting scope of crane gear withoutMethod covers all pile foundation positions etc. and can not or be difficult to transfer the situation of steel reinforcement cage,
Summary of the invention
The object of this invention is to provide the method that the overweight steel reinforcement cage of a kind of caisson is manually transferred, solved construction siteCrane gear cannot put down the situation of steel reinforcement cage, utilizes under the square bearer and steel reinforcement cage on the armored concrete retaining wall that is shelved on pile foundationThe fixing nylon rope of four U-shaped draw-in grooves of portion, manually carries out the colligation of steel reinforcement cage and transfers, and this method has been avoided having used and resetedThe variety of issue occurring when standby has been saved construction cost simultaneously; Contrast other and manually transfer steel reinforcement cage method, this method only needs 2Individually manually just can complete the colligation of steel reinforcement cage and transfer, and utilizing four U-shaped draw-in grooves, providing four supports to steel reinforcement cagePoint, has ensured the balance and stability that framework of steel reinforcement is transferred,
To achieve these goals, the present invention is by the following technical solutions:
A method that steel reinforcement cage manually transfers that caisson is overweight, comprises the following steps:
Step 1, making steel pipe square bearer, prepare the steel pipe of four, and wherein two is pressure-bearing pipe, and pressure-bearing length of tube is greater than reinforced concreteThe diameter of soil retaining wall; Another two is tube connector, and tube connector length is less than the diameter of armored concrete retaining wall, by the end of four sleeve pipesMouth cuts into interior circular arc and is divided into two pairs, and every pressure-bearing pipe two ends are symmetrically welded a pair of sleeve pipe, then tube connector is inserted in sleeve pipe,Finally obtain steel pipe square bearer, finally steel pipe square bearer is placed on armored concrete retaining wall.
Step 2, four plain bars are curved to four U-shaped draw-in grooves with angle bender, the width of U-shaped draw-in groove will be wider than Buddhist nunLong Sheng,
Make first segment steel reinforcement cage:
The first hoop of putting more energy into is carried out decile and carries out gauge point, and isodisperse equates with steel reinforcement cage lengthways main steel bar quantity, according to gauge point,Put more energy into and bind round outside welded reinforcement cage lengthways main steel bar successively at first,
According to the position of steel reinforcement cage lengthways main steel bar, four U-shaped draw-in groove notches making are symmetrically welded to first of steel reinforcement cage downPut more energy into hoop below and a side of U-shaped draw-in groove be welded on steel reinforcement cage lengthways main steel bar in road, and at two adjoining U-shaped draw-in groovesOn be welded with reinforced steel.
Step 3, two nylon ropes of preparation, every nylon rope one end is fixed on a pressure-bearing pipe with fast knot, and the other end is successivelyThrough two U-shaped draw-in grooves, on another root pressure-bearing pipe, be wound around three circles and then remaining nylon rope after winding be fixed on to pressure-bearing pipeEnd, stretching two nylon ropes, are shelved on nylon rope the first hoop level of putting more energy into.
Step 4, progressively upwards colligation when prosthomere steel reinforcement cage.
Step 5, after the colligation of prosthomere steel reinforcement cage, untie respectively the slip-knot of two nylon ropes, simultaneously slowly loosen twoNylon rope, steel reinforcement cage is stressed and steadily decline by being wrapped in the nylon rope of pressure-bearing Guan Shangsan circle, until the suitable for reading of steel reinforcement cage put more energy intoHoop stops while falling hole, then remaining nylon rope after being wound around is fixed on to the end of pressure-bearing pipe, returns to step 4 and continues colligationNext saves steel reinforcement cage, and repeating step 4, step 5 are until the bottom of steel reinforcement cage arrives projected depth.
In step 4 as above, the connection of steel reinforcement cage lengthways main steel bar adopts sleeve to connect, and the rate of plugging in same cross section is not superCross 50%, the every 2m of hoop that puts more energy into upwards arranges one, and steel reinforcement cage tie hoop is wrapped in steel reinforcement cage lengthways main steel bar outside, steel reinforcement cageTie hoop is firm with the contact point welding of steel reinforcement cage lengthways main steel bar.
Four U-shaped draw-in grooves of steel reinforcement cage as above bottom are as four strong points of steel reinforcement cage.
Advantage of the present invention and beneficial effect are:
(1) in the lifting scope that has solved crane gear is difficult to cover that pile foundation position, hoisting machinery are difficult to put in place, caisson overhead is subject toBrace summer obstruction etc. and can not or be difficult to transfer the problem of steel reinforcement cage,
(2) steel reinforcement cage is in the vertical colligation in foundation ditch hole, low to the stockyard site environment requirement of steel reinforcement cage,
(3) making of square bearer and U-shaped draw-in groove is simple, and it is easy to operate that cooperation nylon rope is transferred,
(4) only need two workmans just can complete the making of steel reinforcement cage and transfer, reduced engineering cost,
(5) position of employing four point control steel reinforcement cages, the laborsaving balance that can ensure again steel reinforcement cage while transferring.
