Abstract
The utility model relates to a pile upper-stacked and lower-hung static load testing device. Main beam steel brackets are arranged on the ground at two sides of a foundation pile; two ends of the main beam are disposed on the main beam steel brackets; a jack is arranged between the main beam and the foundation pile; a secondary beam is arranged on the main beam along the direction vertical to the main beam; the secondary beam and the main beam form a counterweight platform; an upper-stacked steel load reinforcing box is arranged on the secondary beam; a secondary beam support saddle also serving as a lower load box and a lower load box are hung at two sides of the secondary beam in the width direction through connecting pieces; a reinforcing baffle taking the shape of the Chinese character Kou(mouth) or Jing(a well) is positioned and fixed in the upper-stacked steel load reinforcing box; and a displacement sensor is arranged on the side wall of the jack, close to the lower load box, to measure the settlement of the foundation pile. The pile upper-stacked and lower-hung static load testing device adopts a hoisting device to add a counterweight to the upper-stacked steel load reinforcing box, and after the static-load testing of the pile is finished, the upper-stacked steel load reinforcing box is taken down at one time. The pile upper-stacked and lower-hung static load testing device is safe and quick in construction and high in efficiency, and adopts mechanical hoisting manner and saves man power and cost.
Description
Technical field
The utility model relates to the preloading device of a kind of construction work ground and the detection of static load of pile foundation lotus vertical bearing capacity, 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 purpose of this utility model is a kind of upper-stacking and lower-hanging combined load static load test pile apparatus.
The utility model technology 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 reinforcement case on pair beam, the both sides paying the beam width direction are symmetrical in foundation pile, pay beam support double load case and following load case down by extension under the connector; 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 the close load case down of jack, displacement transducer is housed, in order to measure the settling amount of foundation pile.
The described road clearance of hanging the load case down is than paying beam support the double big 5-30 centimetre of load case of hanging down.The outer wall of strengthening case at last heap steel work load is equipped with cat ladder and scale.
The beneficial effects of the utility model are:
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 utility model 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.

Fig. 4 is the A-A generalized section of Fig. 2.
The specific embodiment
The road clearance of hanging load case 7 down is bigger 16 centimeters than paying the double extension down of beam support load case 6.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.
