Abstract
The invention relates to an upward-stacking and downward-hanging combined loading static load pile test device, wherein a steel structure bracket of a main beam is arranged on the ground at two sidesof a foundation pile; two ends of the main beam are arranged on the steel structure bracket of the main beam; a jack is placed between the main beam and the foundation pile; a secondary beam is arranged on the main beam along a direction vertical to the main beam, and the secondary beam and the main beam form a ballast platform; an upward-stacking steel structure load reinforcing box is arranged on the secondary beam, and a secondary beam support saddle which also serves as a lower load box and another lower load box are hung downwards on two sides of the secondary beam along the width direction of the secondary beam through connecting pieces; a square reinforcing baffle or a reinforcing baffle with the shape like a Chinese character 'jing' is positioned and fixed in the upward-stacking steel structure load reinforcing box; and the side wall of the jack close to the lower load boxes is provided with a displacement sensor for measuring the settling amount of the foundation pile. The upward-stacking and downward-hanging combined loading static load pile test device adopts lifting equipment to add counterweight materials into the upward-stacking steel structure load reinforcing box, and the upward-stacking steel structure load reinforcing box is lifted off once when a static load pile test is finished. The upward-stacking and downward-hanging combined loading static load pile testdevice has the advantages of safe and fast construction, mechanical lifting, high efficiency, and labor and cost conservation.
Description
Technical field
The present invention relates to the preloading device that a kind of construction work ground and static load of pile foundation lotus vertical bearing capacity detect, particularly a kind of upper-stacking and lower-hanging combined load static load test pile apparatus.
Background technology
The construction of construction-engineering project, particularly highrise building, large-scale structure needs to use a large amount of pile foundations.According to the requirement of country about ground and pile foundation engineering inspection of quality standard, reply foundation pile test pile and engineering piles are carried out the bearing capacity static load and are detected, to determine and to check its bearing capacity of single pile, as the mandatory term of pile quality acceptance requirement.Traditional static loading test ballast platform counterforce device is to use the sand pocket counterweight on the ballast platform; Stack sand pocket very heavy, feel unwell complete, consume a large amount of sand pockets, speed is slow, efficiency of construction is low.
Summary of the invention
The objective of the invention is a kind of upper-stacking and lower-hanging combined load static load test pile apparatus.
The technology of the present invention realizes by following technical proposal: a kind of upper-stacking and lower-hanging combined load static load test pile apparatus, in the foundation pile both sides along same straight line, with the equidistant girder steel structure support of settling on the ground of foundation pile, the two ends of girder are placed on the girder steel structure support, place jack between girder and foundation pile; Pay beam along in a row arranging perpendicular to the direction of girder, the length direction of paying beam is symmetrical in foundation pile and is placed on the girder, pays beam and girder and forms the ballast platform; Settle heap steel work load to strengthen case on the beam paying, the both sides paying the beam width direction are symmetrical in foundation pile, hang double as down by connector and pay second time extension load case that first time of beam support hung the load case and do not made to pay beam support; Heap steel work load is strengthened in the case on described, and positioning and fixing strengthens plate washer with " mouth " font of the big muzzle osculum of foundation pile vertical centre axial symmetry or plate washer strengthened in " well " font; On the sidewall of jack, displacement transducer is housed, in order to measure the settling amount of foundation pile near second time extension load case.
The road clearance of described second time extension load case is hung the big 5-30 centimetre of load case than first time.The outer wall of strengthening case at last heap steel work load is equipped with cat ladder and scale.
The invention has the beneficial effects as follows:
1. adopt hanging device upwards to pile the steel work load and strengthen case and add the counterweight material, after the static load test pile is finished, disposablely last heap steel work load is strengthened case hang down; Construction safety, fast, mechanization lifting, efficient height, save manpower and cost.
2. descend the extension casing to alleviate the counterweight on ballast platform top, help reducing the desired height of going up heap steel work load reinforcement case; Also reduce the whole center of gravity of upper-stacking and lower-hanging combined load static load test pile apparatus, improved the stability of ballast platform and integrally.
3. strengthen being provided with in the case " mouth ", " well " font reinforcement plate washer at last heap steel work load, last heap steel work load is strengthened the lateral wall pressure of case in order to reduce filler, box height be can increase as far as possible, under the identical situation of floor space, maximum volume and preloading weight obtained.The volume that last heap steel work load is strengthened case is determined according to the heap(ed) capacity of test requirements document.
4. the load of static load test pile is very large, and assembly of the present invention adopts the high strength steel member, to guarantee construction safety.
5. the outer wall of strengthening case at last heap steel work load is equipped with cat ladder 2 and scale 3, watches situation and the quantity thereof that load is strengthened the counterweight material in the case for the constructor.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is schematic perspective view of the present invention (foundation pile and the jack that are positioned at the center are blocked by the girder steel structure support).
Fig. 2 is structural representation of the present invention (removing the girder steel structure support of termination, to show foundation pile and jack).
Fig. 3 is the vertical view that heap steel work load is strengthened case of going up of Fig. 2, and strengthens plate washer to show " well " font that heap steel work load is strengthened in the case.
Fig. 4 is the A-A generalized section of Fig. 2.
The specific embodiment
It is big 16 centimeters that the road clearance of hanging load case 7 second time is hung load case 6 than first time.
The outer wall of strengthening case 1 at last heap steel work load is equipped with cat ladder 2 and scale 3, watches situation and the quantity thereof that heap steel work load is strengthened the counterweight material in the case 1 for the constructor.
